Disappointing Day in Dumne

Today was a disappointing day in Dumne. Yakubu, Adams and I drove to Dumne for our third trip there. We planned on re-installing the pump, tank and cylinder I fixed over the weekend. When I tore apart the cylinder I could understand why they say they used to pump and pump and get little water. The foot valve gasket was worn through and the piston cups worn. Today we discovered leaks in the pipes also. Water was leaking out almost as fast as it was being pumped. Our hope was to get this the pump at the school working as a slow recharge pump. This is a pump where you get three or four buckets of water and then wait for water to come back into the borehole. That is the best this borehole at the school will ever do until it is either deepened or replaced. While we are in Dumne we also will check on the status of the Danish Borehole we got working last Friday.

At the edge of the village just before Dumne I saw someone standing by the side of the road up ahead. It turned out to be a straw man near the Primary School. You can see Dumne in the background. The road to the right goes to the Market we went to Friday and to the left goes into the main part of Dumne, (See last Blog).

When we left last week the plumber and driller we hired to work with us had disassembled the borehole by the school and due to a broken head, the tank being stuck to a pipe, and a bad cylinder we decided not to re-install it. We had stored 3 new pipes and the 9 pipes we had removed at the Pastor's house next to the borehole and took the broken parts back to Yola for repair.

Mistake number 1. I ASSUMED that the plumber, being the paid "expert", had inspected the pipes as they removed them and we did not need more pipes. Wrong. Disappointment number 1. Almost all of the pipes that were removed needed replacing. The threads on most had rusted through. As we were re-installing the pipes I realized the mistake. We had left a few pipes stored up the hill near the Danish borehole last week. Yakubu and Adams drove up there and got three better pipes. At the same time they asked the women at the borehole if is had a constant flow. Disappointment number 2. The borehole is slow to recharge and after they have been pumping for a while the water runs out and they go wait in the shade. We will have to bring more pipe and rods from Yola and lower the cylinder another 9 meters. This will put the cylinder at just beyond the maximum depth recommended for this pump. It also makes it doubtful that the borehole will be able to support a solar pump and tank.

Adams decided that only 3 of the 4 pipes stored the Danish borehole could be used. The school borehole was installed by a Chinese driller and the casings were not installed straight. They also used too thin of pipe and when threaded the threads almost went all the way through the pipe. Due to corrosion, they now go all the way through. We decided on the nine pipe to install. From the 5th pipe on the misaligned casing started to cause us problems. We were using a pipe clamp that was bolted to the pump stand. It is suppose to center the pipe over the center of the borehole. That works when the pump base is installed with the casing centered in the pump base. Unfortunately, the pump base was not centered over the borehole. The pipes were going down the side of the borehole and the cylinder was carching at each casing joint. We had to open the clamp all the way and remove the pipe from the clamp at each joint, get it past the joint and put it back into the clamp. Until we were installing the 8th of the 9 pipes we were going to install. We could not get it past the joint with the clamp attached to the pump base. So we told the boys who had the lifting tool (C-wrenches) to hold the pipe while we removed the clamp. Mistake number 2. We did not watch the boys while Yakubu was taking the bolts off that held the clamp to the base. They relaxed. Someone touched the clamp release bar just enough to loosen the clamp from the bar. The  eight 3 meter long pipes quick slide down the borehole. I yelled. The clamp did its job and stopped the pipe when the top coupling hit the clamp. No one was hurt.

Now mistake number 3. This mistake probably prevented a serious injury. We had not installed the T-handle on the 8th rod sticking up out of the 8th pipe. We looked at the pipe now flush with the clamp and someone said where is the rod. The rod was no longer sticking out the top of the pipe. That means that a pipe joint in the borehole had broken. The fall never hurts you. It is the sudden stop at the bottom. The sudden stop had ripped the eighth pipe out of the coupling from the lower seven pipes. If the T handle had been installed. It may have caught the lower seven pipes and we would not have 7 pipes and 8 rods at the bottom on a 9 1/2 pipe deep borehole. On the other hand. Yakubu had leaned over the pipe clamp to unloosen the bolts and if the tee handle had hit him with the weight of 8 pipes falling three meters the T handle would have caused him serious injury. Safety, Safety, Safety. We get so focused on the task at hand we do not step back and look at the whole picture. We had too many people around the work site. It is good to learn lessons when no one is hurt. As we used to say at Home Depot. Many of the safety rules were made after blood was on the floor.

On Friday we arrived with a non-functional borehole and left with a non-functional borehole. Today we are leaving with a non-functional borehole with a cylinder, 7 pipes and eight rods resting on the bottom. Adams will return after I leave with a "Fishing Tool" that can be lowered into the pipe and catch onto the rod that is about 5 meters down. They can then lift the string of pipes and rods out. They will bring along new pipes for this borehole and a few more pipes for the Danish borehole. We will lower the pump cylinder to the maximum recommended depth on the Danish borehole and the women should be able to pump more water with less stopping each day.

On good thing happened today. The bailer I built and brought last year got it first use today. We successfully demonstrated that we can pull the mud out of the bottom of a borehole without a compressor.To have completely removed the mud from this borehole we would have had to bail for several hours. We did not have that much time. We quit after four 5 gallon buckets. We got most of the sand and grit out but the fine mud just mixes with the water. The common way to remove mud and sediment is to hire a compressor at around 40,000 to 60,000 naira depending on how far from Yola the work site is. We could hire local labor at 1000 naira per day in most villages (in a town the size of Dumne we would have to pay more.) If we hired 4 young men per day we could have them bail for five days for 1/2 the price of a compressor and it put money into the village rather than a Yola based contractor's pocket. I also sent the video camera down the hole. The water was clearer than other boreholes but the focus changed once under water and I could not see the any detail of the pipe or screens (assuming the Chinese contractor installed any screens.)

On our way out we stopped at the straw man for more pictures.
this will be my new Facebook Profile Picture. When we stopped in the village the women who we resting under the a large Neem tree broke out on clapping and laughing when they realized that  Bature (White Man) was stopping to get his picture taken with the School Crossing Guard. They told us that when the Primary School is in session they put up this straw man to tell people to slow down.
