Philippe Lacour-Gayet is currently Founder and Treasurer of IDO, an NGO working on helping people in Africa with drinkable water supply. From 1997 to 2007, he was Vice-President and Chief Scientist of Schlumberger, a large oil service company, in charge of the R&D function and managing directly the five Research Labs of Schlumberger.
Philippe spent all his career in Schlumberger, starting in France in 1974. He worked in the US, UK, France and Japan, in Research, Engineering and Marketing positions. Prior to 1997, he managed Schlumberger Technology Centers in France and in Japan.
A mining engineer and physicist by training, he graduated from “Ecole des Mines de Paris” in 1969, and obtained a Ph.D. in Physics from University of Paris in 1974.
The Logone Oriental region is one of the most populated regions of Southern Chad. It is a rather flat savannah, where most of the population lives in villages with an average population of 500 people. The regional capital, Doba, has roughly 100,000 people, and the region around 600,000. Most people work in farming, raising cattle and small artisanal industry. People are quite poor. Villages have no electricity or running water, but there are water wells in most villages.
It rains around 1,300 mm a year: supply of water is not an issue. There are two types of improved water systems: open large diameter wells and drilled wells equipped with pumps. Since the early 1990’s, there has been a significant effort to equip villages with wells, either from large international donors (Unicef, AFD, EU), religious organisations (Catholic Church, World Vision), oil companies, who exploit several oilfields in the Kome area (Esso) or the government of Chad, who has a program devoting 5% of the oil revenue to the local area.
The large diameter wells have a big advantage: they do not break down, and water is always available, except in the case of a severe drought. But the quality of water is not very good: polluted items can fall in the well, and the water needs to be treated. Drilled wells equipped with pumps provide usually excellent quality of water, but the pumps can and do fail.
Our IDO volunteers come from the oil industry working in the Kome area. They are all Chadian, often originally from the area and are technicians working in the oilfields. Most of them are technically very competent. IDO employs a full time person who runs the organisation in Chad, who is a Chadian from the area and speaks the local language (Ngombay). We have a pickup truck and a guesthouse in Doba to house our volunteers during their missions.
IDO started operations in the Logone Oriental in December 2009.
We started first by doing an inventory of the water wells in our area. As of June 30th 2011, roughly 18 months after we started, we have inventoried 214 wells in 124 villages. Out of these 214 wells, only 64 (i.e. 30%) were operational when we saw them first. Some of the broken wells had been down for 5 or 10 years, but there were also some very recent wells, less than 12 months old, that were down.
We found 4 types of pumps: Vergnet, India, UPM and electric. We counted 7 electric pumps, (2 working), 24 UPM pumps (2 working), 29 India pumps (10 working) and 154 Vergnet pumps (50 working). We have concentrated on Vergnet and UPM pumps, and we have not yet addressed the India or electric pumps. The situation of electric pumps is very disturbing: often they replaced working manual pumps, yet most of them are down because the electricity supply, either generators or solar panels have been stolen. In this paper we concentrate on the Vergnet and UPM pumps.
When we asked a village if they had tried to repair the broken pumps, most responded that they had tried, but were not successful, either because they could not find a reliable artisan-repairman, or that spare parts were difficult to get. We also noted that the village chief, invariably a man, is not above asking the village women to walk to the next working well sometimes many kilometers away, and carry back the water. When we asked the artisans-repairmen why they did not repair more wells, they said they had difficulties in getting paid, and that repair was not a very good business, so they had to do something else (bicycle repair is popular). Yet, we found 5 artisans-repairmen in the area who have been trained at the time of the drilling of the wells. We also found reliable spare parts suppliers in Moundou, a large city on the western border of our region. The suppliers have parts for Vergnet and India pumps. UPM is a different issue we discuss at the end of this section.
After some early trials and field training of our volunteers, we developed a strategy we call Awareness- Diagnostic- Repair (ADR).
In about half the cases so far the village does not call back after the diagnostic and estimate. However, this is becoming less frequent as our reputation for getting pumps to work becomes known in the region.
For UPM pumps, which are quite old (most were installed in the late 80’s), there is the added issue of the French pump manufacturer gone bankrupt: spare parts were not available. To solve this problem, we have designed and manufactured ourselves these spare parts, and we have installed them in one of the pumps, with great success so far. After confirming that our spare parts work well, we plan to follow exactly the same ADR approach as described above.
When we started in Chad in 2008/2009, IDO received from Planet Action both satellite pictures from Chad and two copies of the ArcInfo software, which have been extremely useful to map our progress. We thank again Planet Action for its support!
All our results have been mapped using ArcMap and we have produced large maps (A0) that are given to local authorities and our partners. These maps play an essential role in showing the real situation in the field, making local authorities realise the seriousness of the situation. Region map.
Using our ADR strategy, we have made 51 repairs on 45 pumps (some pumps failed more than once). The average total cost of repair for the village is 125$, 110$ for spare parts, 15$ for the repairman. This compares with an amount of 10,000$ for drilling and equipping a new well. The most expensive repair so far was 950$, and the less expensive around 1.3$, yet in all cases there was no problem for the villages to pay.
We were quite surprised by this, but we understood that because of our approach, the villages trust that the well will work afterwards, and that they will not be overcharged for unnecessary spare part replacement (something the artisans-repairmen used to do, impossible now under the watch of our technically competent volunteers). As a result of our action, the percentage of working pumps went from 30 to 50%. If we look at the Vergnet pumps only, out of 154 pumps, the number of working pumps went from 50 to 94, and the percentage from 32% to 61%.
The lessons learned are as follows:
