What Is The Problem?
The mission hospital does not have a water supply in the true sense of the word, i.e. there is no running water.
There is a hand pump on the premises, but it is defective. As it is not a branded product, there are no spare parts. Quite apart from that, a hand pump cannot be used to establish a water supply, but only to fill jerry cans.
At the moment, water is fetched with canisters from a stream about 1 km away and filled into plastic containers in the rooms. These have a tap under which there is a bowl to collect the dirty water. The bowl serves as a washbasin. The hygienic conditions are correspondingly poor.
Can We Get Water?
The management of the mission hospital has asked us if they can get a water supply like the hospital in Adi. From our point of view, the conditions are unsustainable for a hospital where people are supposed to get well again. That is why we decided to tackle this project.The project includes the following work:
- Check whether the old borehole in which the defective hand pump is installed has enough capacity (litres per hour). A pumping test is carried out for this purpose.
- If the borehole provides enough water, a solar pump will be installed there. Otherwise, a new location for a borehole has to be found on the hospital grounds with a geophysical measurement. A solar pump is installed in it.
- The water is pumped into a 10-metre-high elevated tank when the sun is shining. From there, the water flows with sufficient pressure into the supply pipes to the hospital, which are yet to be built.
- Washbasins will be installed in the rooms.
- The polluted wastewater will be piped to septic tanks. The septic tanks will be located outside the catchment area of the groundwater.
We Have Already Carried Out The Following Work
December 2019 - Drilling
The Mission Hospital has hired a hydrogeologist and a drilling company to locate a promising site for a borehole on the premises.
Unfortunately, the hydrogeologist's work was not very good. At the calculated location, there was only 500 litres of water / hour at a depth of 84m. That is too little for a water supply.
2020 - No Works
During the Covid-19 pandemic, travel to Uganda and from there to the Democratic Republic of Congo was not possible.
We dismantled the existing defective hand pump and carried out a pumping test. The result of the 24-hour pumping test is that a maximum of 1,100 litres of water per hour are available.
The well was not drilled professionally in 2007 and was therefore very silted up. It is only 31 m deep and is therefore not suitable for the construction of a water supply.
The Next Steps ...
- The first drilling is done at the newly calculated location - 120m deep.
- Then a pumping test is necessary to measure how much water is available per hour.
- Based on this value, the pump is selected and an elevated tank is built.
- From there, a main water line will be laid to the hospital.
- If there is enough water, the school about 300m away is also connected to the water supply.
