Trip Summary

I was asked to write a Reader's Digest version of my last 2 1/2 months in Nigeria for a newsletter. I figured I would write a summary blog on my last day here. I am mostly packed and ready to head to the airport in about 5 hours. In all this was a successful trip. There were some frustrations. I had delayed my trip a few weeks so I would arrive after the Health Board had there two weeks of administrative training. Their training got delayed two weeks. At the end of the trip there was problems with transferring money to a driller and that delayed the drilling of the Waya borehole to the very end of the trip.

I should introduce myself for those who do not know me. I am Jay Johnson. I am a professional engineer. I am a retired Lt. Colonel from the US Army and Army Reserve. I have traveled extensively in my military and professional careers. Since 2006 I have been traveling to Nigeria annually. The first two trips were short two week visits with the Minneapolis Areas Synod / Global Health Ministries Public Health Evaluation Team. Starting in 2008 I visited by myself for visits of 6 week to 10 weeks. In 2008 my purpose was to start learning the people and culture. I visited all the Dioceses of the Lutheran Church of Christ in Nigeria and over 100 villages. This is when I composed my three priorities for village water. 1. A village wants to have enough water to survive. 2. They want the water as close to their village as possible. 3. They want safe water.

The Lutheran Church of Christ in Nigeria is based out of Adamawa State. Adamawa is a rural state in the northeast part of Nigeria on the border with Cameroon. It is mostly savannah. Deforestation is almost complete except in a few preserves and hillsides too steep to farm. They have two seasons. Dry season is from October to June. Rainy season is from June to October. In the southern part of the state the rainy season is longer and in the northern area it is even shorter. In the capital Yola the annual rainfall is about the same as Minneapolis. Except it is concentrated in a short period of time. Farming is mainly a rainy season business. We have had several rainfalls and the countryside is turning green. The vacant farm fields are now busy with people with hoes, or cattle pulling plows and tractors plowing. The sorghum has sprouted in some areas and the maize is being planted. On weekends the people from the cities head to their villages and plant their crops.

My original purpose in coming to Nigeria was to start my retirement career as a non-denominational water, sanitation and development consultant. All of my trips have been centered on clean water and sanitation, but have included work in community development. The three main organizations I work with are the LCCN Health Board Water and Sanitation/Hygiene (WASH) Team, the LCCN Deaf Centre and Spring of Hope HIV/AIDS Support Group. Over 90 percent of my efforts are with clean water.

This trip had a slow start as my main contact Yakubu Bulama the Water Coordinator for the Health Board and Projects Coordinator for the LCCN was working with the Health Board Administrative training for the first two full weeks I was in the country. I spent these weeks setting household in the old mission house on the LCCN Compound and visiting with the Deaf Centre. The guards at the Cathedral Church in the adjoining compound called my house the "falling down house."

 My travels this 10 weeks has probably totaled around 4,000 kilometers (2,500 miles) by road in public transportation and in LCCN owned vehicles. This was the most dangerous part of my time. Many of the drivers are not licensed. Some went from riding bikes to driving cars. Others drove motorbikes and drive their cars the same way. Few know the rules of the road. When I got my license I paid an extra 1,500 Naira ($10) so I did not have to talk to the driving examiner. The manager just gave me my license and told me that was what the extra money was for. 

Water accomplishments: There are more accomplishments than disappointments. Some of the disappointments are actually accomplishments (or steps towards accomplishments.)  The main two accomplishments were fixing the water distribution system at Banjiram and drilling two productive boreholes at Waya and a third at Polchi. (Waya and Polchi are in Bauchi State and are mission villages of the LCCN churches in Jos, Plateau State). We also were able to go to Timbukum, in the southern part of Adamawa State to start the review of the non-functional solar powered borehole that the Nigerian Government with money from the US Government had installed and never worked. We found that the pump was installed at the very top of the water table. The next phase which will do done after I leave will be to determine if the borehole is deep enough to lower the pump to under the water. We be a preliminary survey of the broken water system at the Government Secondary School in Hong that the PTA had asked for our assistance. In Pella we got to review the large hand dug well near the LCCN Maternity Clinic to determine the possibility and estimated cost to clean out the bottom of the well, cover the well and add a hand or powered pump. This is a highly productive well that has had continuous water for several decades. The water was over 6 feet deep. The hardest part of this project will be to find pumps capable of de-watering the well so the well diggers can enter and remove the several decades of debris that has accumulated.

Disappointments: We performed a geophysical survey of two points in the community around the Sabon Gari B District Church on the edge of Mayo Belwa. The survey indicated that there was not a significant amount of groundwater for a productive borehole at the two locations surveyed. However, there are several productive motorized boreholes operating in the area. The next thing for the community to do is to go to the owners of the productive boreholes and find out how deep they are and if possible measure the static and dynamic water levels. Likewise, the geophysical survey of the area where they want to install a borehole at Gada Biyu in Bauchi State found very little indication of groundwater. We have asked the geologist if an improved hand dug well might be possible. This village may require some more innovative system for obtaining water during the dry season.

Other Work: LCCN Deaf Centre is moving towards being able to serve more of the Deaf Community of Adamawa. Last week the Yola Bishop requested that the paperwork for the Ordination of Ruth Ulea as the first deaf pastor in the LCCN be forwarded to the Jimeta District Church. By tradition a candidate's home district is suppose to call pastors.Ruth's home church is in Arewa Diocese in Hong. They have sat on her application because she does not serve their community and for some other reasons. The LCCN Constitution on specifies that a District Church will call a pastor. In Ruth's case she provides Sunday School and church services in Jimeta and several other locations in the Yola Diocese. We fixed most of the roof leaks in the patio area where Ruth holds Sunday Services and I bought 7 sets of jewelry and some bracelets that some of the women make to support the Centre. They normally sell them for 300 naira in the local market. I talked them into sell them to me for 500 naira. I will be putting them up for bid on a website for a minimum of $10 (1,570 naira) with the profits going back to the Centre. I have started work on some concept designs for improvements to the LCCN Deaf Centre and improvements to the location that Church services are held at until a new church can be located, designed, financed and built. I was able to attend a meeting of the Spring of Hope HIV/AIDS Support Group. A part of the group has been trained in soap making. They only need $400 to buy the molds and ingredients for their first batch of soap. They have test marketed some of the soaps in their home villages and found that market to be more viable than in the more competitive Yola market. I hope to raise the $400 as a micro-loan when I get back to the US. I have made progress on fixing my "falling down house". The main opening that rats and mosquitoes come in through has been screened. There are two major roof problems that are washing away some of the mud bricks in the kitchen wing that will need attention soon or the kitchen wing will fall down. For the first time in the last three trips I have been able to stop and shop at Women of Hope store in Jos. I will be leaving the country broke but I purchased 71,000 naira of their merchandise. It will be for sale at the Mount Calvary Annual Fair Trade Fair the first weekend of November. I have a great tan from the elbows down and since I have driving the last month the left arm is now balanced with my right arm.


I almost forgot. After three years of sitting in Gaye Guyton's living room. The boxes of books that were collected for the Remi Foundation, the books I collected for the Bronnum Lutheran Seminary and the LCCN Deaf Centre arrived in Jos and I picked them up Saturday when we were there for the Waya borehole drilling. They were all distributed on Monday. The Deaf Centre library went from about a dozen books to almost 100. They are considering allowing the students to take some of the books home to read overnight. I have been in locked libraries at schools. Most schools to not have a library at all. The Jimeta Cathedral school has a room in their new expansion designated for a library but does not have books. The culture of reading is very small. Most students only read text books and some have workbooks.

Sabon Gari District Church in Mayo Belwa

Goggle Earth Image from 2006. VES 1 is by the church VES 2 further up hill past the exist broken borehole.



I do not know how many times I have been to the area around the Sabon Gari District Church since 2008. The community is on the edge of the town of Mayo Belwa. But it is not in the Mayo Belwa Local Government Area. They are in Furfore Local Government Area. Across the highway and down the road a little way is the Secretariat for the Mayo Belwa Local Government. An easy walk from this community. But they do not get any services from Mayo Belwa. Furfore where their local government is located is about an hour by car south of Jimeta and they are about two hours north and east of Jimeta. Fufore LGA does not give them much services either.

The community got organized and hired a “so called driller” to drill them a borehole. He did not have a very strong rig and he did not charge a lot. He drilled down to his limit and had barely hit water. The people talked him into drilling deeper. After he drilled a little deeper he told them that his mud pump was not powerful enough to pump the mud out of the hole so he installed the casing and screen into the drilling mud and left. Long story short, they went through several “so called drillers” before they finally agreed to work with the LCCN WASH program and got the pump working. It did not last long as the pump stand and casing are misaligned and people pump on it from morning into the night.Today they told us that they hired someone from Jalingo in Taraba State to come and repair the pump and it is broken again. Adams and I agree that the rod is probably disconnected from the piston. I am going to figure the cost to put a small borehole pump into the casing that does not matter if it is misaligned. To give them the same amount of water flow as the hand pump which as about all this borehole will produce will probably be the smallest borehole pump made. Since the pump will probably cycle on and off as the water level drops it would waste a lot of expensive fuel to use a generator. A small solar system will make more sense for a daily operating costs. 

We were not in the area today to fix the pump.The community is interested in a second borehole and we had brought a geologist from the Upper Benue River Authority to do the geophysical survey to find a good spot for the new borehole. It had rained the night before and remained overcast to the weather was nice for working. Julius started by dowsing the area using two wires. If they opened up the water was getting less and if they closed the water was increasing. He first worked the area around the Sabon Gari church and decided on a spot. We set his equipment to do a resistance survey to determine the apparent depth to the water. 

I was first introduced to dowsing in the mid 1980’s when investigating a grain elevator explosion in southwest Minnesota. A local farmer informed me that there were old drain tiles running from the building that exploded out to a creek about a mile away. He grabbed some wire from the rubble and bent them into an L shape and proceeded to dowse for the pipe. He marked where the pipe was. I thanked him. Later that evening I took the wires and crossed back and forth where he said the pipe was and got the same reactions. I figured it was just my subconscious controlling the wires where the farmer had shown me. I continued doing cross sections out into the fields and found the outlet of the pipe about a mile away. Since then I have dowsed for wires and pipes, but I have never tried it for water. For me there was water everywhere and some areas where they diverged indicating less water. I would rather review aerial photographs and geological maps. But in built up areas like this the land has been disturbed and geological features have been obscured. I have an open mind. I still think there are some clues your mind is seeing in the area that makes you manipulate the wires.

After the finished the resistance test at the church site, Julius set out around the community looking for more areas that his wires told him there was water. He did not get much of an indication and decided on the second test area after about a half hour of walking around the area. This spot happened to be near the house of the man that was showing him around. This has already created talk about “why at his house. Why not at my house”. The second site is up hill and in from the dirt road that leads through the area. Its main advantage is that it is up hill. So when you walk to the site with your empty containers you are walking uphill and then downhill with the full containers. Most of the community will not have to walk uphill with their full water containers.The church site will be downhill for almost the whole community. 

After we finished the resistance surveys of both sites Julius choose we were invited by the Water Committee Treasurer to go to Twin Sisters Restaurant for lunch. They had four tables inside and two on the outside. The twin sisters are the Treasurer's sisters. I had my regular, rice with soup (red sauce, spicey, with two pieces of beef). Today they just had rice or pounded rice and soup.The area behind the sisters in where the food is dished up. I think the actual cooking is done out the behind the building where they can hand the food in through the window.
 As I was typing this into the computer, I was at my desk in the middle of the room under the ceiling fan. A young boy maybe 10 years old yelled from the street "White Man, How are you?" He was more polite than most of the street kids that yell through the fence. I noticed he was selling sachets of cool water. So I walked out to the fence and bought two sachets from him. The water in my frig was colder. so I put his in to cool down and went back to work.

Timbukum Another Government Project That Does Not Work


Timbukum
Our day started early. Yakubu Bulama showed up at a little after 6 AM. He is driving his old Toyota van today. The Health Board is using the Hi-Lux to visit one of the Community Based Public Health Care (CBPHC) sites. They are doing community surveys of the villages around the Bingia and need the four wheel drive truck. We will be headed south to the village of Timbukum. It will be several hours of pothole dodging. The section of road from Mayo Belwa to Ganye is one of the worst in Adamawa. Not as bad as the Lamurda road but much longer. Each way will be nearly 4 hours. Our original plan was to drive down the night before, stop at Dashen Bible College to look at their pump problem. Stay overnight in Ganye and meet with the Bishop in the morning before driving the last hour down to Timbukum. We found out that the Bible College did not have a problem and the Bishop was going to Yola for a meeting. So we decided to make it a long day trip.
Roadside Food Stand

I was up at 5 to shower and make some breakfast. We stopped and got gas, cool water to drink and some engine coolant at a station on the edge of Yola and headed out of town. Yakubu and Adams had not had breakfast. So we stopped at the first village outside of Yola to buy some roadside eats. The lady had fried yams, fried sweat potatoes and bean cakes. We got a small bag of the combination of all three and headed on. Yams here are a large tubular without a lot of taste. 

Yakubu’s van is 16 years old. As you go up hill the temperature rises and as you go down is lowers. We had to stop once on the way there and once on the way back to let it cool down. The mechanics here do not believe in thermostats. Most vehicles have had them removed. They also do not add coolant just straight water. I told Yakubu that the coolant helps the radiator from boiling over. He had purchased some coolant when we stopped for fuel. He added it to the radiator when we stopped the first time. The engine is behind the front seat and the radiator and fan is between the driver and passenger seats

 We passed the Bonotem Bishop in Jada as we were finishing the bad part of the road and he was headed into it. We arrived in Timbukum around 10:15. I went to look at the old pump that was slow to recharge back in 2008 when I last visited here and found it was still slower now. When you stop pumping you can hear the water leaking out of the riser pipes. Yakubu could not find the church chairman but a white man walking around the village drew a crowd. We spent about a half hour talking to the people about the hand pump. Then we got directions to get to the solar powered borehole.

Timbukum is a village north of Toungo in the south end of Adamawa State. At the request of the local church through the Bonotem Bishop the village has requested assistance in finding out why the Millennium Development Goal solar powered borehole and tank does not deliver water. This is one of the government projects that the village did not know about until the driller showed up and started drilling. The borehole, tank and tap stand are located at the government Dispensary. If you click on the picture you will get a larger picture you can see better.

Upon arrival at the pump we could hear the distinctive sound of the pump trying to pump water and air. The people present reported that in the morning they get one or two buckets of water then it only drips all day. It appears that the pump is set at the water table rather than below. We found water at 70 feet with the water level indicator. We shut down the pump and waited a half hour. There was no significant recharge. Also, indicating the pump is set at the top of the water. We decided to pull the pump but discovered that the power cable does not have any slack. It enters the borehole through the cap and is cemented into the concrete base. To lift the cap and pull or add pipes to the pump will require the cable to be cut and additional cable spliced on. We did not have the additional cable or tools to do this work. We could not determine the depth of the borehole without removing the pump.
After listening to the pump I climbed the tower to see how the solar panels were connected to the pump. The wiring job was very professional, with all loose wires secured. The circuit breaker that I turned off at the top of the tank had never been switched off since it was installed in 2008. After switching off the pump I laid under the solar panels waiting to see if there was any recharge. After they determined that there was no significant recharge we decided to pull the pump. As I swung around to climb down the steel ladder I smashed my right shin on something. I climbed on down and then we discovered that we could not pull the pump. So I went back up to turn the pump back on. It did not want to turn back on. Yakubu climbed up with a screw driver and I disassembled the case and cleaned out are the wasp nests and mud wasps nests and still could not get the circuit breaker to stay in the on position. I removed one of the two plastic bars that were holding the two switches together and pushed as hard as I could and it finally clicked into position. We will be leaving with the pump working the same as before. No worse and no better.
Best Case: The best case for this project is that the borehole was drilled to over 100 feet deep and the pump can be lowered into the water by three or more pipe lengths (30 or more feet). Lowering the pump will provide more water above the pump to be pulled into the pump. The pump will draw the water down in the borehole causing the water in the ground to flow into the borehole. Pumps will operate best at a minimum of 3 pipes under the water table in an aquifer that is quick to recharge. In slower recharging aquifers the pump will need to be much deeper. There are indications from the other water sources in the area that this will be a slower recharging aquifer. If the pump can be lowered then a water level probe needs to be added to the pump to switch the pump off when the water level starts to reach the inlet to the pump. This will create a non continuous flow but will increase the pump life. Pumping air is not good for a pump.

Worst Case: The borehole is drilled to less than 100 feet and less than three pipes can be added. A new borehole will need to be drilled. The first step in this process will be to perform a geophysical survey of the area to determine the apparent depth to water and the thickness of the water. Unfortunately, the location of the tank tends to restrict the location of the borehole to a reasonable distance to the tank for pumping and electrical wiring. Based on a short review of the general geology of the area it is anticipated that the borehole will be drilled through a shallow layer of overburden and into weathered and hopefully fractured basalt or other volcanic formation. The area is shown on some maps as recent volcanic activity. Recent in geological time scale. If this is true than it is possible that below the volcanic formation can be layers of formations which could be contain significant water. Drilling through the assumed volcanic layer will be quite costly. The geophysical survey will provide a more accurate estimation of the hydrogeology of the area. Since the village never requested or were not consulted about the borehole they do not feel it is their borehole. They may not be willing to spend much money to fix the situation.

We left Timbukum around 1 pm and headed to Dashen Bible College. Earlier as we had crossed a bridge we saw some boys in the middle of the walkway of the bridge selling mangos. We stopped and bought mangos. The were selling them at 10 Naira each. Fresh and tree ripened. We each washed one off and eat as we drove to the Bible College.

Dashen Bible College provides education to Evangelist and Catechists and also has a Secondary School. They have posted some of the highest scores on their various levels of exams in all of Adamawa. Their PTA had raised money and drilled a borehole on the school grounds. They had not consulted with the WASH Team and hired a driller without doing any geophysical survey. The borehole was successful but they had some problems with the pump. Back in February the principal had asked Gary of Global Health Ministries for some help. This was the first chance that the WASH Team had to come down this way. In the mean time the pump had been repaired. 

 
After a short visit we headed back towards Jada. We drove around Jada looking for a place to eat. None of the spots we found looked to clean. We headed back out of town when I spotted a small spot with cooking pots out front. It was a two table restaurant. The kitchen is at entrance. That is Yakubu's van out parked outside. They had pounded rice with sauce or vegetables. I had the red sauce with a couple bits of beef and a almost cool Pepsi. The even had spoons, forks and knives in a basket at the table. We were not in Numan. (That is a story from last years blog. Eating at a restaurant in Numan we asked for a spoon and knife and the waitress said “This is Numan.” )


 We also had time to stop in Mayo Belwa to see the pump that we have been working with for the last three years. It appears to have a broken rod. There is a rather long story about this pump, bad driller, followed by bad driller, and then the water committee chairman making off with the funds. The use is so heavy on the pump that it tends to break a lot. There may be an alignment problem The second bad driller had trouble aligning the pump over the borehole and ended up taking a cutting torch to the tank to make it fit. Then kids through rocks through the opening and jammed the pump. This year the rod is broken. I would not be surprised to find debris in the pump again. I think they need a new tank and head. The profits from the 2008 fair trade sale at Mount Calvary were used to support this project. Part of the stolen money.

In all we had a successful day. I am fairly confident of our findings in Timbukum and it is now three days later and I have not gotten sick from the roadside meals. I no longer limp and the shin only hurts when I twist the knee.

Ngbekendiwe - New Water Source Proposal



Ngbekendiwe: Try to pronounce that three times fast.  The "Ng" is mostly silent. With my level of hearing loss it is silent. The name means “place where grains are stored”. The village asked the Todi Diocese for assistance and the Bishop referred the project to the Health Board WASH Program. This was the WASH Team’s third trip to the village (my first). The WASH Program emphasizes community participation. In many past projects the participation was limited to contributing a little labor and collect sands and gravels for the concrete. The WASH team has learned that this limited participation did not produce community ownership. Now they are requiring a minimum of 10% up-front cash. People get serious when Naira is involved. But they have never been asked by a church or the government to participate in this way. This is something new to them. The WASH Team tries to emphasize that they are not here to give a gift to the village but to help the village to build create a sustainable project that they will own and operate.

Small Store near the LCCN Church.
This is not a very poor village, but not a rich village either. It has small stores and other local conveniences.  The village structures are mostly made of mud brick and thatch. There are a scattering of concrete block buildings with aluminum roofs. It is a clean and well kept village. There are several clay pits in the village for making mud bricks. This will be mosquito breeding grounds in the rainy season. The village lies above a tributary to the Benue River. This whole area was alluvial at one time. The village is a linear village along a small ridge line.


Dry borehole. Tank and all pipes have been removed.
The government has sent “so called driller” to install boreholes in the village. Mostly, around election time. Of the four that they told us about only one ever produced any water and the water is “salty”. Here salty means hard not necessarily tasting like table salt. Many time the driller can go deeper and get better tasting water. The trouble is that here they drill will not seal the boring between upper layer of “salty” and lower layer of water. 


Ngbekendiwe was about 1.5 kilometers long in this 2007 Google Earth Image.
 At today’s meeting the WASH Team met with the Chairman (also the local Imam), the Secretary and one committee member of the local water committee and the pastor of the local church. The other four members could not be found. They reported that they have formed subcommittees in different wards of the village and they have gone to the Local Government and received the proper papers to be a recognized social agency and can now open a bank account. They did not know how much money has been committed to do the project. Yakubu encouraged them to get the subcommittees working and collect the money needed to meet the 10% minimum. Open an account at the nearest bank and deposit the money collected. Soon the rains will start and they will be busy planting their fields. 

Yakubu , Adams, Chairman, Secretary , Committee Member and the Pastor
In earlier meetings they had been told several options creating a new water source. They had chosen to have a motorized borehole with a generator, pump, tank and a distribution system. The cost estimates they were given were general in nature. Specific, design and detailed cost estimating have not been done. I currently, have my doubts that this project will happen this dry season. The road to the village looks like a stream bed in many places. If they get the funds together by the end of April the new borehole could be drilled before the main part of the rainy season begins in June.

Back to Banjiram

Goggle Earth Image of Banjiram and the location of the taps. At the end of the blog is a view wider view.
My idea of by-passing the tank and pressurizing the water line to get water to flow at the remote taps was a little off base We went back to Banjiram last week to check out some details. One of the main items was to find the specifics of the pump data from the pump box. The box is gone. Someone had a use for it so it was taken out of the storage room and the paperwork is gone. Another was to check the actual distances the water had to travel. I was told 75 meter to a junction and then 150 meters in two directions to the remote tap stands. Actually it is 160 meters and 200 meters. These lengths make my idea not feasible except if you wanted to take 10 minutes to fill a 20 liter container.
Tank outlet configuration
 The next thing was to see what was buried underground. Once we had finished digging up the connection of the tank outlet to the remote taps Yukubu showed me the picture he took when they buried them. This is the pipe coming down from the tank outlet. The 2 inch pipe has two elbows to get around the foundation and underground it has a Tee. The right side stays at  2 inches and only goes about 6 meters where it goes into the School Tap Stand.
School Tap Stand with school in background
The school does not want the people from the town coming to the school to fetch water. They have allowed their borehole and tank to be used to supply more people in the village but they built two remote tap stands closer to the homes.

The picture on the left is the North Tap Stand and on the right is the South Tap Stand. You can see the school and the tank in the background of the North Tap Stand. Notice there are pots only lined up at the end two taps at the North and a well worn path to the school. The South Tap Stand has  buckets at all of the taps but mostly on the north end where the water comes in. The North Tap Stand is actually up hill from the school and the south is slightly down hill. We did an experiment and turned off all the taps at the School Tap Stand and we opened the tank. All the taps at the South got water. Only a little water on the North. Based on my hand level I am guessing the North Tap Stand is 2.5 meters higher than the borehole.

The two remote taps stands get little flow when the school tap stand is open. Resulting in people walking to the school every afternoon to fetch water when the tank is opened at 3:30.

I spent much of the weekend and Monday doing manual mathematical modeling of the piping system trying to come up with a solution that will work. There are also village politics involved. My best solution would not work because the farmer who owns the field will only allow one trench through his field. He had to be convinced to even allow one. He has a tractor plow his field. The plastic pipe will not withstand a plow hit.


Here is the solution I am currently proposing. We will still use a new pipe to by-pass the tank and pressurize the pipes with the pump. This should add up to 2 more meters of water pressure. But the 2 1/2 inch by-pass pipe will now continue down the trench along side the existing 1 1/2 inch pipe and go all the way to the north end of the North Tap Stand and connect there. In my models this solution started to work at a 2 inch pipe. But there are several unknowns that I could not put into the model. The exact elevations is one and the capabilities of the pump and pump controller. This was the first time since college I have run mathematical models by hand. Fortunately, I found a website that would calculate pressure drops for me. I several liters of fuel in my little generator while doing it. I ran the calculations for around 10 different combinations of pipes. If someone like me shows up in the future and sees the way this is piped, they will wonder "What kinds of drugs was the this guy on, when he decided to run the pipes like this?".

Just tot he south of this Google Earth Image is the dry river bed where much of the town gets its water by digging.
