We're back in Delaware. THANKS TO ALL!

We returned to Delaware last night - safely, without any delays, tired but happy. About half of my "tan" has come off in the shower.
Supporters of EWB-UD, we thanks you so much.  Knowing we were travelling on the basis of contributions, large and small, and knowing that you are following our work, makes a huge difference.  The folks in the villages know that too, and Mayor Mukam has expressed his own appreciation many times.
A few final notes:
 - getting back to Yaoundé, we got a call from the U.S. embassy and they met us to do an audio interview about the project. They promised it would be posted on their web site. Watch for it here.
 - it looks like I will have to have my tooth extracted. See earlier post for why.
 - our wonderful ally, Olivia Mukam, has posted her story of our project here. Take a look!
More pictures to come!

The final days

Yesterday was a roller coaster.  It started off generally crazy and nervous while we got ready for the Big Occasion.  Olivia had come up with her mom and two friends and she was extremely helpful in converting my short speech into real French from Franglais.  They also spent a lot of time putting together a big board with dozens of photos illustrating our project over the years, which went off to the school to be exhibited for the ceremony.  The school was whitewashed and decorated with woven palm fronds.  Announcement banners were hung across the road from Ndang to the school.  Tents were set up to shade the plastic chairs being set up for the occasion.  A carpenter built wooden steps to enable dignitaries to easily climb up and look into the water reservoir.  The school’s tapstand was remortared for appearance’s sake.  A slow leak at the reservoir’s exit pipe was patched and reinforced.  I called the U.S. Ambassador’s staff to confirm their arrival at 10 am.

In the mean time Felix, our plumber, was doing last minute repairs. We had located a significant leak in a feed line to the reservoir the day before, so this was repaired. Flow to the reservoir from the well at Bakang II went way up, but this caused a new leak adjacent to the ceremony site, discovered about 9 am. I heard a rare expletive from Felix, but he replaced that pipe section quickly, and sealing these leaks gave a higher flow rate into the tank, which increased significantly as the sun rose.   

We returned to the Mayor’s house in time for a call from the Ambassador’s entourage. They were arriving in Bamendjou, so we met their vehicles at the Ndang intersection and escorted them to Mr. Mukam’s house for introductions and a nice breakfast in the large dining room.  We enjoyed speaking with Ambassador Jackson and his wife, as well as Jon and Katy Koehler, the Cultural Attaché and his spouse. There was spirited conversation about development strategies, involving the other officials also at the table.

We then continued to the village school.  For me, this has sometimes been the most peaceful place to reflect on what we’re doing, as the mild wind blows through the eucalyptus trees. But today, it was abuzz.  Hundreds of school children, three different crowds of uniformed women, a microphone system, officials directing cars where to park among the rocks, and a voter registration table.  Most of the local people were in their traditional dress, including many of the area chiefs. The Ambassador was presented with flowers by a schoolgirl, another student read a poem, and we went through a long line shaking hands with folks (some of whom I’ve now known for years). 

After everyone sat down, there were speeches by numerous people of import, plus me (I will add my speech at the end of this blog).  The most entertaining was the lead-off, by the chief of Bakang I, but it was in patois  and we never got a translation to go along with the gestures and laughter. The representative of the state’s Governor spoke, then the Mayor, then our U.S. Ambassador, then me, and then Mike, with translations into patois (and Mike’s from English to French, too).  I presented Mr. Mukam with a pipe wrench that we had spray painted in gold, and Mike presented him with the maintenance manual. There was a lot of singing and dancing, and presents given to the Ambassador and to me (more on that later).

Olivia was given the headdress of a village queen—a great honor, well deserved for her work in getting our project off the ground six years ago.

We then walked up to the water reservoir.  I explained the system for the Anglophones, and the Mayor explained for the (vast majority) Francophones.  The VIPs peeked into the reservoir, which had a nice flow coming in, and checked out the water at the school’s tapstand.  Below, you see the United States Ambassador to Cameroon, Robert P. Jackson, approving of our water!!!  After that crucial test, and a few more formalities, we proceeded to the Town Hall in Bamendjou for a sumptuous lunch.

Then it was over. We went back to the house, changed clothes, and 30 minutes later we were again bushwacking along the Bakang II distribution line, in a cloud of dust, trying to locate a leak or blockage.  By the end of the day, we had located the flow problem and came back to the house sweaty, dusty, and exhausted. No water or electricity. It seemed to me like the ceremony had been days ago!
That evening we opened two wrapped presents that had been given to us. One was an Oumbé cane, decorated with shells, and the other was a locally made basket.  Nice.

But I was most struck by the first gift presented to us earlier in the day: a heavy bag full of potatoes.  Really. This was a small field’s worth of cultivation and care, of considerable value to the women who gave it to me.

Later, one of them had thanked me personally and, looking me straight in the eye, had said that they were thinking of how their potatoes would be enjoyed by our families far away in the U.S.  I told her I love potatoes, and thanked her deeply.  Of course we must leave them with acquaintances here, but the gift was very memorable.

Today we’ve wrapped up some loose ends in Bakang and Bamendjou, and are now in Bafoussam for the internet.  Tomorrow early, we take off for Yaoundé and home.   Sorry for so few pix - we'll add more when we have real internet.

"If we had known it was illegal, we would do it again." aka "Dentel Problems"

Today was the big day!  Everything that everyone has been working on for the past six and a half years is getting commemorated today in the ceremony, and everyone's tensions are running high.  It started off on a high note during breakfast when Dr. Steve took a bite of his peanut butter sandwich, only to discover a tooth in it.  It was not his tooth.  And apparently it hurt his already aching tooth.  Dentel problems, indeed.

The mayor went out to the site early in the morning and reported that nothing was working and called us sounding very alarmed.  Because of this we went to the community in our nice clothes, and inspected everything.  It appeared that everything was in working order and would just take some time before the PE tanks were full enough to have the wet wells start pumping.  There was a big tree that was shading the solar panels at Bakang 1, and when Dr. Steve told this to the Mayor, Ramsey and I joked that the tree would be down by the time we got down the hill from the reservoir to the crossroads.  However, during the middle of Dr. Steve's phone call, we could all hear a chain saw start up, and everyone had a good laugh.  Fortunately, that tree is still standing, and hopefully will be for a while.  After we decided that the system was in working order, we headed back to the Mayor's to greet the US Ambassador to Cameroon, Robert P. Jackson.  We met the ambassador at around 10:00 and the Mayor had prepared an early morning treat for everyone.  We dined in his main dining room, which is pretty incredible as people who have seen it will remember.  Ramsey, Erica and I met the two other embassy staff members, Jon and Katy, who had some pretty cool development projects planned and sounded really interested in our projects, current and upcoming.

We eventually made it out to the school, about an hour and a half later than was planned on the ceremony program (Cameroon time I guess).  Once there, the ambassador was given a hearty greeting by all of the dignitaries there.  The ceremony went off without a hitch, with Dr. Steve and me delivering speaches.  Dr. Steve gave Mr. Mukam a golden pipe wrench, while I presented him with the (almost) final draft of the operations and maintenance manual.  After everyone had given their speeches, it was time to actually go look at the tank and see water coming out of the tap there.  Everyone was really impressed with what our chapter accomplished, as am I!  Thanks to everyone who has ever worked at all on this project!  After we visited the tank everyone started clearing out, but we hung around and took pictures.  Thanks to Ramsey's previous trip knowledge, Dr. Steve's rock is now a little less lonely.

After Dr. Steve's adventerous jump off of his rock, we went to the town hall where a celebretory lunch was being held.  Dr. Steve was seated at the table of honor, along with the ambassador, while Ramsey, Erica and I ended up sitting with a really interesting rural engineer with the Department of Energy and Water.  The lunch was fantastic with all kinds of traditional Cameroonian dishes (yes there were plantains and chicken).  Lunch went surprisingly quickly, and was over by 3:00.  After lunch was over, we headed back to the Mayor's to change clothes and head back out to Bakang 2 to see if we could find a possible leak in the distribution line.  Erica and Ramsey stayed at the Bakang 2 panels to take some measurements for this float switch issue, while Dr. Steve and I went with a couple locals to try to find where this break was.  Marcel had told some of them that the line was disconnected somewhere, but neither I nor Dr. Steve knew anything about this.  When we called Marcel, he told us the line was complete.  Because of this, there were plenty of people upset with Marcel.  Dr. Steve and I watched as there was a big argument about who to blame, which was definitely more interesting given I couldn't understand anything being said.  Marcel eventually showed up and we spent maybe an hour and a half searching for where there was water in the pipe.  After all of this time, we found a spot that did have water, but it quickly disappeared.  Felix was trying to explain that there wasn't enough pressure in the line to push the water through the pipe, but I didn't really buy that as the run out is pretty much entirely downhill.  Eventually, someone had noted that Marcel disappeared because there was a cleanout in the line upstream that everyone had forgotten about.  All of a sudden, there was water coming out of the cut pipe again.  The good news was that we had figured out the main issue with the Bakang 2 distribution line, but now we have to fix the parts that we cut testing for water and check for leaks tomorrow which shouldn't take too long.

P.S. The title of this blog is courtesy of a story Dr. Steve told us about speaking bad french. Forgot a negative, apparently.

Egotistical Chemical Engineers Learn How To Actually Build Things

Today we woke up and were feeling confident about getting everything done that needed to be done.  Over breakfast, Ramsey and Dr. Steve were talking about how awesome the local church is and how cool the service is.  Because of this, Erica and I decided to go to the service and then head down to the community after.  Unbeknownst to us, the services in Cameroon are a lot longer than at home, so over two hours after the service had started, we had made it back to the Mayor's to pick up Dr. Steve and Ramsey.  We went out to the community with all of our diagonal braces for the solar rack prepared to fix them.  As we were driving, I got this sinking suspicion that although our holes lined up with the flat pieces, they wouldn't line up with the rack because of the fact that the c-channel could attach to the rack two ways (flipping 180 degrees around its long axis).  This fear was augmented when we got to the site and two of the Bakang 1 pieces didn't fit onto the rack in any feasible way.  However, our local mechanical expert (Dr. Steve) quickly sorted out our problem for us by explaining that we should put bolts in as placeholders and then tighten everything down later.  Although our holes were still not perfect matches, this let us put everything together.  It's a good thing that chemical engineers learn this kind of thing in school.

After the racks were assembled, I called Dr. Steve to see what he and Ramsey were up to, and he told me that we should walk up the Bakang 2 line checking for any breaks.  When Erica and I got to the top, Felix was just finishing replacing a bit of pipe in the Bakang 2 line that had apparently been bludgeoned with a pick axe.  It was kind of mind boggling that someone would have done that, but luckily it was an easy fix and so we began to inspect the rest of the system for any kind of tampering.  Dr. Steve and I bush-wacked our way through head high grass from the Bakang 2 chief's to the junction box, which is how we spotted two leaks in the supply line to the ferrocement.  Unfortunately, we still didn't know why there was no water in the Bakang 2 distribution line, but we hope to figure that out tomorrow.

Mike Relearns His Multiplication Tables

Today Mike and I woke up early (6am) to beat Dr. Steve out to the work area, something that has not been accomplished on the past few trips.  We watched the sun rise as we drilled holes in the aluminium for the replacement pieces of the solar racks.  After breakfast, the team headed to Bafoussam in order to check e-mail and post all of the blogs we had written while here.  The first internet cafe we tried was closed, the second only had one open computer in a cramped corner.  The third internet cafe that we found had internet that was so slow after 15 minutes we gave up. Luckily, Dr. Steve knew of a nicer hotel (Talotel) that we could connect to their wifi using his laptop.  A couple hours later, the blogs were succesfully posted, e-mails had been sent to our parents, and a copy of the book had been downloaded.

When we got back to Bamendjou, Mike and I stayed at the mayor's to finish drilling the holes in our solar rack while Ramsey and Dr. Steve went out to the system to take another look at the float switches and see what had been accomplished.  While drilling, Mike and I learned that the previous holes on the two racks were 5/16" while the bolts we had now were 3/8".  However, upon counting the number of bolts that had been bought before the trip, we learned that we were quite a few short.  Mike realized that he somehow managed to multply 6x8 and get 24 rather than 48.  This wasn't an issue though as we decided to use the old nuts and bolts that will fit in the holes on the racks in those holes, and the new, slightly larger bolts for the connectors.  The new issue is that we were 7 nuts and bolts short.  A quick trip into Ndang allowed us to pick up the remaining pieces, and Mike and I were able to finish putting together the supports.

When we finished this, we needed to spray paint a pipe wrench gold for the ceremony on Monday.  Unfortunately, the nozzle of the spray paint came off in the tool bag while in transportation to Cameroon.  Mike managed to get the nozzle back on, but in the process of painting, gold paint covered his hand, giving him the "Midas touch."

Ramsey has packed the team a few surprises, and has been down in the kitchen with Martine cooking, and we are excited to find out what this surprise will hold.

Dr. Steve Drinks Wine and Sleeps

This morning we got a tour of George's (the chief of Batougouong) compound and even got shown the central building of the compound where all of his ancestors were buried (very cool!).  After he showed us around his house we took a walk out to the tapstand nearest Bamendjou, on the road from the cow pond into town.  Here we discussed what would be done with this tapstand to prevent overuse.  Once we had finished at George's we drove over to the chief of Bakang II where there was a meeting going on to discuss the plans for the day.  At this meeting we were introduced to the chief and discussed some of the things that we wanted to get done.

Once we had talked with them, we decided to get on our way so that we could get everything finished.  We first headed out to the ferrocement tank at the top of the hill to see what was happening up there.  Felix and Felix had found some burned conduit that needed to be replaced on the Bakang II float switch line.  Unfortunately, this had never been buried, so a brush fire had destroyed part of it.  Erica and I headed down the hill to take care of the conduit while Ramsey finished the connections at the tank and Dr. Steve parleyed with the mayor.  Once word got out that the mayor was present everyone burying the conduit to Bakang II left except for one very helpful local, Justin.  He showed Erica and I a very quick way to splice the conduit and replace the parts that needed to be fixed and sped up the process greatly.  After the conduit was finished, we headed back up the hill to see what was happening at the tank.  By this time, Ramsey was finished with the connections, and he and Dr. Steve went to the Bakang II tapstand down the road near the chief's house.  In the meanwhile, Erica and I walked down the hill to Bakang I and then over to Bakang II to see what the situation was at both sites.

At Bakang II we found some of the locals hanging out underneath the shade of some avacado trees.  Erica and I saw that they had cut down the bamboo grove that had been surrounding the borehole and it looked a lot better which I tried to tell them in butchered French.  We then learned that one of the locals there, Pedro, knew English very well.  I told him that we were trying to get the solar panels and tanks cleaned, and we also wanted to get access to the wet well cleanout which had been buried.  At around this time, Dr. Steve, Ramsey, and Felix drove up and came to see what was going on.  Pedro greeted Dr. Steve and almost immediately offered him a glass of boxed (Spanish) wine.  Dr. Steve said the wine was quite delicious and so Ramsey tried some as well.  After this very hearty greeting, we saw Marcel cleaning the solar panels, and he helped us to unbury the cleanout.  On testing the cleanout, we determined that the water inside was very clean (hooray!) but that mud got back in because the cleanout trench wasn't sloped enough.  Once this was taken care of we all headed back to the spot that I had located in the Bakang I line as most likely having the break (with Ramsey's Dad's awesome Christmas present).  Ramsey located the spot more exactly, and we and some of the locals started digging while Dr. Steve went to look at another tap stand location.  Ramsey soon found what looked like a fox hole, and was pretty confident that that is what caused the break in the line which soon afterward he triumphantly proved.

As Ramsey worked on fixing the break in the line, Erica, Dr. Steve, and I went up to the school to unload all of our gear out of the truck because Felix and Felix needed to go to Bamendjou for tap stand materials.  While we were up at the top of the hill, we decided that it would be good to test the float switches once again as they should all be operational at this time.  I walked the Bakang II line down the hill and mapped it on Ramsey's GPS so that we have that information in the future.  After getting to Bakang II, I saw that the tanks were empty after being cleaned, so there would be no way to test the float switches there.  Instead, I walked down to Bakang I where I met Ramsey who had finished connecting the line and had determined that the float switches were just awful because they still weren't working.  I decided to take the AM radio and toner up the hill while Ramsey placed the exciter on the Bakang I float lines.
The tank is almost full!
Meanwhile, at the top of the hill Dr. Steve had decided to take a nap on top of the control box, which Ramsey has renamed the water sarcophagus.  When I got up to the top of the hill he looked plenty comfortable, and Ramsey called just as I got up to the tank.  We checked the line and determined that the lines were continuous all the way to the float switches, which was a good thing.  I decided to walk down to Balatsit and check on the float switches there and see if they were working (they weren't :-( ).  When I came back up, I took a look in the tank, and the water was covering the last of the concrete steps and was probably six inches from the float switches.  It was really awesome to see so much water in the tank, but also kind of nerve-wracking as the tank could possibly overflow tomorrow.  Ramsey has put on his thinking cap to try to figure out how to get these float switches working (the theory right now being that there is too small of a current in the wire for the controller to sense).  Tomorrow we have plans to fix the solar racks that were constructed with flat pieces of aluminum rather than C-channel or L-beams, and head into Bafoussam to prepare for the ceremony coming on Monday.  Everything seems to be wrapping up nicely here, thanks for all of your support!

The obligatory Dr Steve sleeping photo.

Dr. Steve reflects, plus a couple pix!

We’re doing it.  On Monday, we officially hand over the water system to the community. There will be a big shebang, for sure. The town officials are tense and keep asking us if the reservoir will be full on Monday when everybody arrives (the answer is yes).  Tomorrow, all FOUR water committees will be out in force, cleaning up the neighborhoods in expectation of all the government officials who will be here.  Banners will be hung across the roads and the school may even get a coat of paint.  Our system is gaining recognition as a crucial resource in the dry seasons, when it’s the only open source of potable water for many miles, remarkable for villages that aren’t even on the electrical grid.  We’re told it’s being looked at as a potential model for other areas in Cameroon. We’ve done something special, and you, our members, alumni, parents, and financial supporters, should be very proud.

As planned, we’re putting the finishing touches on the system.  Ramsey has already given you the details.  Just a couple pix here, ‘cuz the internet is pretty non-existent.

Here’s a cool thing Ramsey brought, being demonstrated by Erica and Mike. Ramsey is down the hill in Balatsit with an AM exciter attached to the wire comes up the hill to a float switch in the tank, to tell the pump when to shut off. To tell if it’s connected, and even where there might be a disconnection underground, Erica listens to a beep – beep-beep sound with a little AM radio. Mike is talking to Ramsey, telling him yes, we have a good connection. Bravo! On the Bakang side though, we found a place we have to dig up to reconnect.  But hey, we would have to dig up the whole thing without this gizmo!
Mike and Erica using the wire exciter and AM radio
This other picture is the inside of our 20,000 liter water reservoir at the school. There is a LOT of water pouring in, because all three wells are busy sending it up.  We re-did the float switch setup inside the tank to make maintenance easier, as also shown.  This tank supplies water for lots of folks!

The inside of the ferrocement tank.
So that’s where we are. Friday is a big work day for everybody and we will try to relay news to you asap!

As Julie says - Peace, Love, and EWB  !

Today We Fixed More Things Than We Broke

What a great day we had today!  We fixed some things.  But most crucially Felix the driver and I figured out that his car MP3 player could play the music on my phone's microSD card.  We spent all day jamming out to Fela Kuti, Michael Franti, James Taylor, and probably about 20 CDs worth of live Phish.  Everyone had a certain spring in their step today.  I think the rest of the team was down with the tunes.  Maybe they liked them.  But more than likely they were just happy to listen to anything besides 10 or so American pop songs that we had been hearing on repeat for the last three days.  I will definitely be leaving some music with Felix before we leave Bamendjou.

First thing this morning we stopped at the metal man's shop and drove him, his generator, and his welding gear out to the ferrocement tank to install a new bracket for holding the float switches.  His welding set up was pretty amazing, and he made quick work on the job.

Once the welder was finished, Felix (the driver) and Dr Steve took him back to town and met with some local officials, while the rest of us got to work on diagnosing the pump issues at the Balatsit wet well.  Based on controller errors from the day before we suspected an issue with the connection to the pump and began the process of draining the wet well so we could pull the pump and check connections.  The disconnecting of the poly pipe into the wet well led to a pretty significant amount of water spraying everywhere.  I imagine it looked pretty hilarious to anyone watching.  Erica and Mike went to make sure that there was no water flowing from other wet wells or the ferrocement tank back to Balatsit (there shouldn't have been).  However, eventually the water drained completely, and Felix and I were able to completely remove the pump.

I was overjoyed to find the problem was not a bad pump.  As suspected there was an issue with poorly waterproofed connections in the wet well.  Most of them had been soaked all the way down to the wire and up the insulation, leading to significant corrosion.  In fact when I was removing electrical tape one of the connections just fell apart in my hands.  I stripped back some wire, but ended up replacing almost all the wire that had been submerged.  Connections were waterproofed using waterproof butt splices, waterproof heatshrink, and finally waterproof electrical tape.  By this time the whole team was back at the well site, and the pump was reinstalled in the wet well and we performed a test successfully.  For the first time in a very long time, possibly ever, all 6 pumps are now functioning correctly.
Ramsey making test connections which were later redone with waterproof crimps, heat shrink, and tape
We also found out that Felix (the plumber) knows more English than originally thought.  He was able to yell, "STOP IT!", when he realized one of the connections was loose and spraying water everywhere again.

Once we had sorted out the pump, we directed our attention to testing the float switches.  As best we could tell some or all of the float switches were not functioning properly.  This hadn't really been a problem since not all of the wet wells were always running, and the ferrocement tank had never been full.  But with all pumps working, it looks like it will be a matter of days before the tank completely fills, and the float switches will be essential in preventing any overflow.

We were able to quickly determine that the float switches themselves were functioning correctly.  This left the connections and wiring running down the hill to all the wet wells.  Very quickly we realized that all the connections at the ferrocement tank were suspect, and much like before, some were corroded or physically fell apart.  Dr Steve and Mike used the wire exciter and bush whacked their way down the line to locate a single break in the wire to Bakang I.  This will be dug up and repaired tomorrow.  We also found that the conduit running to Bakang II had never been completely buried, and some of it had been melted due to the slash and burn agriculture used in the area.  As best we can tell the line to Balatsit is intact and will just need to be reconnected at the ferrocement tank.  This work will probably take up at least the first half of tomorrow.  While some of the team addresses these issues, the rest of the team will be checking all the tap stands in the community to insure they are functioning.

The local villages have called a special work day tomorrow in preparation for the hand off ceremony on Monday.  Significant cosmetic work will be performed around the wells, school, and ferrocement tanks.  This is a good thing since I leaned on a rickety fence today and broke part of it.  Everyone is really excited for the ceremony on Monday, and I can't wait to see all the work the community is going to be doing.

One thing that has been very concerning is that Dr Steve forgot to bring his gold and silver stars on this trip.  We've had to resort to intangible "credibility points".  While my credibility is pretty high these days, I'd trade it all for a single gold star.

Wire Exciters Are Awesome

This morning I woke up feeling like a million bucks.  I set up my hammock outside to escape Mike's snoring, and even though I was woken up by a squawking peahen it was probably one of the best nights of sleep I've ever had in Africa.  Not one mosquito bite, either!

Sleeping Easy
We discovered that our generator had been broken while we were out of country.  This was mildly frustrating, but considering our drill is locked away where we can't reach it, the generator wouldn't be much use anyway.  We put these issues aside, and dived headlong into addressing the electrical system issues we had diagnosed yesterday.

One of the biggest problems I anticipated was that we only had a foggy idea of where the wires running from the ferrocement tank float switches back to the wet well controllers were located.  I had spent many hours helping my dad locate breaks in the invisible dog fence around my parents' yard, and it was never fun.  With roughly 4km of underground wire in Cameroon, I was even more apprehensive.  I recently picked up an underground wire exciter for $50 from Brackmann Engineering.  While something much fancier would have been nice, we have a limited budget, and I was fairly confident it would do the trick.  It basically works by sending an AM radio signal down the wire, and then you can use a portable AM radio to locate the wire to within a 5 feet or so.  It's not super precise, but it's good enough for wire finding, and great for determining if there are breaks in the line.  It was pretty fantastic Christmas present for my dad which I immediately confiscated and took to Cameroon.  Dad, if you're reading this, I promise to bring it home and help you fix the dog fence again.  It should be easy this time.

While Felix the plumber, repaired a leak in some of the plumbing at the top of hill, I repaired a break in one of the float switch lines.  Most wires, are not designed to be exposed to the elements, and unfortunately, this wire had not been properly sealed/waterproofed in conduit and buried.  Because it wasn't buried, it was a fairly straight-forward repair.  Before completely sealing the lines, I also used the wire exciter to determine if there were any other breaks in float switch wires, and was very happy to find that they were functioning as expected.  With the help of Mike and Erica, we have already GPS mapped the path of one of the wires, and given time and a machete we hope to map the other two lines.

After completing the repairs to the float switch wires, we turned our attention to repairing the faulty controllers.  At Bakang 2 wet well we swapped in a brand new controller and determined that the pump was functioning perfectly and that the controller was indeed faulty.  Since the old controller seemed to have limited functionality we decided we put it back in place and took the new controller to Balatsit 2 to replace the controller that was seemed to be completely non-functioning.  After making the replacement though, the CU-200 presented an F3 error, indicating no connection to the pump.  Some diagnosis using both the wire exciter and a wire toner indicated that there were connections all the way to the bottom of the pump (where the wire enters the pump housing).  Measurements of the resistance through the pump indicated that there was still a connection through a motor coil in the pump.  It's a perplexing problem that may require us to pull the pump from the wet well to check all connections.

While we did this work Dr Steve and Felix went around installing the new push taps at all the tap stands.  The new taps are wonderfully simple, and should prevent water waste, while also preventing the spread of germs from the tap to the water.  Almost every tap stand we visited on Tuesday had dripping, leaking, or left-open taps.  The new taps should really prevent this.  Even the youngest kids were quickly able to understand and use the taps.

We ended up heading back to the Mayor's house relatively early at 4PM, so that we could test a broken pump.  I had done this previously back in the DE so the process was fairly straight-forward, but as always some in-country ingenuity was required so that we could plug in the pump directly to mains power and submerge it in a make-shift wet well.  Resistance measurements of the pump indicated an open circuit, and it wasn't much of a surprise that when we did hook up the pump it didn't work.  Little Guy (one of the little boys who lives at the Mayor's house) seemed somewhat disappointed we were unable to soak him with water.
Using local materials to make a VERY leaky testing wet well.
Dr. Steve left us to test the pump while he tried to use the local internet cafe (again).  We have some exciting guests expected for the hand-off ceremony on Monday, and Dr Steve is busy orchestrating things as best as possible with limited internet.

As I write this post, Mike and Erica are busy cutting aluminum to replace some parts of a couple racks, and Dr Steve is reviewing video and photos we've been taking.

Tomorrow the metal man (welder) will be helping us remount the float switches while most of the team plans to attack the Balatsit wet well.  Assuming the pump is not completely broken and we can get it pumping again, the entire 6 pump system will be working and we will be leaving the system to the community in working condition.  It will be no small feat, and has taken 10 trips, 6 years, and a lot of hard work by many dedicated people to make it happen.  Crossing our fingers!

Making Up For Lost Time

We arrived in Bafoussam Monday night, after a 4 hour very uncomfortable bus ride.  Erica ended up sitting in a Economy Minus (a wooden box in the aisle with an armrest in each kidney).  I have never been so close (physically) with one of my advisers   Needless to say this was a great sacrifice for Dr. Steve since there was no water at our hotel and I hadn't showered in a couple days.  We were picked up by George Takam, a local chief, who helped us find some much needed dinner before taking us back to Bakang.  Upon arrival in Bamendjou we found out there was also no running water there, so showers had to wait another day.

Despite the delayed start for this trip, things are moving along nicely.  Today was our first day on site, and we spent much of the day taking stock of all the borehole and wet well pumping systems.  We were very pleased to see that the all of the borehole systems were functioning as expected, with all tanks filling each day, despite the dry season.

Unfortunately only one of the wet well/lift systems was working, which meant that the ferrocement tank was not filling fast enough to keep pace with demand from the gravity fed distribution system.  This problem has become more pronounced recently.  Due to the dry season and municipal water shortages in Bamendjou, many people had been travelling to the edge of Bakang to get water from the system we had installed.  On one hand, it was encouraging that the system was so well known and trusted for safe drinking water.  The downside is that there has been additional demand from a userbase that has little invested in the system.

We also inspected the 20000L ferrocement tank, plumbing, and various tap-stands.  The ferrocement tank is in great condition, and will only require a minor modification which will allow for easy changing of the float switches, without draining the tank so somebody can climb in it.

Based on some initial evaluations we determined that the wet well at the Balatsit crossroads was completely non-functioning due to a faulty controller which had been exposed to direct sunlight and has been suspect since the last implementation trip.  At Bakang 2 the wet well was functioning sporadically, but apparently correctly.  However there was no read out or status information on the CU-200 controller and internal diagnostics indicate the controller is at least partially faulty.  The wet well at the Bakang 1 crossroads was functioning exactly as expected.  Tomorrow we will attempt to confirm that the controllers are the faulty component by substituting in working controllers

Testing electrical connections in the pump controller
One observation we made, which has been made before, is that the controllers are very popular nests for insects.  We removed bee/hornet nests from every controller we opened.  I also spent an hour in the afternoon attempting to clean "insect glue" off the circuit boards of old controllers using alcohol.  While we may not get a complete working controller, hopefully there will be some spare parts.  Quarterly cleaning of the controllers will need to be part of the recommended quarterly maintenance.

While I was cleaning the rest of the team went to Baffoussam to pick up some supplies.  Wire was purchased, along with some reducers for the specially selected push taps that Dr Steve found.  Felix, the plumber, and Felix the driver, have both been very helpful through all of this.  Dr Steve picked up an overpriced Union Jack towel to use in the now working shower.  Mike and Erica grabbed some local fabric which we later delivered to the local seamstress.  Later in Bamendjou attempted to send an email to my roommates, but was foiled by a power cut right as I was signing my email.  Going forward, all correspondence will be prepared ahead of time on a laptop.

Arrived in Yaounde!

Last night we officially reached Yaounde!  The team made it through the airport fairly quickly with all of our baggage and got to the hotel.  Today we are trying to do a few things in Yaounde, and then we will be taking a bus to Bafoussam, so we will be in Bamendjou by tonight!

Ramsey Vents and Eats Waffles

Due to the snafu with our flight from Dulles, we were unable to get any of our clothes last night in DC.  But we were assured that during our 26 hour unplanned stopover in Brussels we would be able retrieve our bags, so that we could get showered and put on some clean clothes.  United did not want to guarantee us accommodations in Brussels but after some belligerence we were given an assurance that we'll probably have a room when we get to Brussels.

This morning I logged into United's site and reserved aisle seats towards the front of economy class for myself and Erica.  When I got on the plane though, I realized that our seats had been changed to the back row of the plane, with me sitting in a window seat.  Despite having plenty of open seats on the plane, it took a certain amount of conflict to convince the stewardesses to find me an aisle seat.  I have to say they were really friendly, but it was a bit off putting that they were worried about being disciplined for giving me a replacement seat (that was empty) for the one I had reserved that morning.

We arrived safely in Brussels this morning around 6:30AM.  We spent the next 5 hours waiting at the airport for our bags to come out.  Which was just as well since the hotel did not have any open rooms because they were all filled with United passengers who had missed connections the night before.  Best we can tell the watches and clocks used by the folks at Brussels airport do not operate on a linear time scale.  Five minutes is apparently longer than an hour but sometimes shorter than 15 minutes which ranges from half an hour to 2 hours.  After hours of waiting we did retrieve some of our bags.  But unfortunately for Mike, his bag is still MIA.  As well as our med kit which is a pretty serious issue.  We have been assured that they know where the bags are (somewhere in Brussels airport).  The baggage attendants have told us that our bags will make it to Yaounde because they know exactly where they are.  Unfortunately in the 18 hours since we arrived they have not been able to bring them to us at the luggage desk, or our hotel that is literally across the street from the baggage claim.  At this point I've stopped giving them the benefit of the doubt, and I'm getting nervous about our tool bag, which we agreed to leave checked for the flight to Yaounde.

Honestly, this might be the worst air travel experience I've ever had.  United Airlines has failed on just about every front.  Missed flight, missed connections, missing bags, last minute changes to our seat reservations, etc.  All along the way the employees have been very nice, but somewhat clueless.  Thanks to the US and EU passenger rights laws, they were forced to put us up in a hotel and give us food vouchers.  Unfortunately the food vouchers didn't cover one meal at the hotel in DC.

So as it stands we have already lost two days of project time.  And without our med kit we stand to lose more days waiting for it in Yaounde.  I'm not sure United could pay me to fly on their airline again.  Luckily for them I'll be eating my words when I have to fly home on United.

Mannekin Pis
So in the mean time we've been trying to make the best of our time.  We did get to spend some time in central Brussels which was really beautiful.  We did a rapid speed tour of Brussels, and managed to visit three churches, Mannekin Pis, Brussels Town Hall and some parks along the way.  We also had a delicious Belgian waffle for lunch out of a waffle truck (a great idea for back home!).  I had been hoping to get some Belgian fries, but Dr. Steve had a bit of a scare when he couldn't find his passport.  Luckily for all of us, it was back in his room.
La Fontaine Egmont et de Hornes
We also had some constructive conversations over breakfast about future EWB-UD projects.  With the Cameroon and Guatemala projects coming to an end, the chapter has been discussing a lot of great project ideas.  It should be exciting to see what the new project(s) end up happening.

So tomorrow morning we expect to leave for Yaounde, arriving that night.  We are all excited to get to Bamendjou and finish the project.  I'm personally excited to get back to Bakang and see all the work the team has done since I was last there and also to see how my work has held up.  We're also excited to reconnect with all the community members who have helped make this project happen.

I imagine our internet access will be getting scarcer in the near future, but we will do our best to keep the blog posts coming.

Status update

Hey Everyone,

Unexpectedly, we have traveled 126mi ( in a little over 15 hours.  This is pretty good mileage, for horseback.... Fortunately, we are not traveling by horseback.  Planes should be a little faster, but faulty engines do slow them down.  After our flight out of Dulles being delayed by 2.5 hours and then aborting a take off attempt, the flight was eventually cancelled.  We ended up at a nearby resort for the night and will have a new flight tomorrow afternoon at 4:50.  The new flight is as follows:
UA 1763 to Brussels, at which point we will spend 26 hours in Brussels.  After that we are on BA 371 into Yaounde.  We will still be letting Amy know when we touch down in Yaounde, at which point everyone will be updated.  As for right now, we have utilized local in country contacts to find a local eatery for a late night dinner as Ramsey and Dr. Steve missed it.  Hopefully the rest of our trip goes smoother.  Will post at the next available location (Brussels?).
