The drilling team
Not far from the water bladder where people are crowding, the ACT/Caritas drilling team is busy sinking other boreholes.
A team of eight manages the rig that has the capacity to drill a borehole in one day. The team plans to drill twelve boreholes altogether in Garsilla with the drilling equipment, which is small enough to be towed by a car.
"If the yield is good we set up a water bladder, but if the yield is not so good we put up a hand pump," says the supervisor of the drilling team, Adam Mohamed Abdalla.
A bladder allows for setting up taps so that more people have access to water at the same time. This is not the case with hand pumps, which can only be used by one person at a time.
The drilling team has already set up two water bladders in Garsilla, and three more bladders are on the way.
Before the drilling bit hits water, it has to bore its way through layers of clay, rock, and sand.
"It normally takes five to six hours to reach the water. It depends on the formation," explains Adam Mohamed Abdalla, who has five more boreholes to drill in Garsilla before heading west to Um Kher.
Every one and a half to two meters, the team takes a sample of the formation in order to know which bit to use. The boreholes can be as deep as 48 meters in Garsilla.
When the bit hits water, a blue plastic casing is put down and water is pumped up until it is pure. The drilling team takes a sample of the quality of the water and sends it to a laboratory before constructing the platform around the borehole.
ACT/Caritas does not have any plans of digging new wells in Garsilla, because the ground is very rocky, making it tough to dig, but ten wells will be rehabilitated to accommodate the needs of the host community.
According to international sphere standards, each person is supposed to have 15 liters of water per day to sustain livelihood, but to reach this quantity is difficult. Every day ACT/Caritas receives requests from villages that need water. The needs are simply bigger than the capacity of the operation. However, a second drill rig is expected to arrive in Darfur soon, to help fill the gaps. |
