The wait

The major displacement of people in Darfur is challenging the access to water. In Garsilla, West Darfur ACT/Caritas is working full speed to drill boreholes in order to meet the need of the people.

One can spot the dark shadows of women placing their jerry cans in a long line in front of the taps in Ardeba camp outside Garsilla town. It is not even five o' clock in the morning.

The women sit down patiently and wait for the guard to turn on the generator that pumps water into a big water bladder that is connected to several taps. At about 6:30 a.m. the water starts running and the women rush to guard their jerry cans.

A young woman explains that she spends five to six hours every day fetching water, although she lives only 500 meters away from the bladder. The water runs out of the taps three times a day, but the line is long if your jerry can is not among the first ones in the line.

The 25-year old woman is in charge of fetching water for her family of six — her two brothers, mother, her husband and two children. The family uses about ten to twelve jerry cans a day for drinking, cooking, washing and bathing.

Before ACT/Caritas put up the water bladder, she used to fetch water from a wadi — a streambed that carries water during the rainy season — two kilometers away. It took her two to three hours there and back, and the line was shorter, but she prefers to wait for the water closer to her shelter.

"When you do not have a donkey and you have to carry all the water on your head, the distance to the wadi was too far," she says.

Ardeba Camp is only one out of three camps surrounding Garsilla where ACT/Caritas provides water. Garsilla camp, with its population of 32,000 displaced people, and the host community of more than 42,000 people, are in great need of water to accommodate the large number of people who have fled their villages.

"Before we came to this area of Ardeba camp there was only one well for more than 1,000 families, and now it has dried out. The need for water was really big," says the ACT/Caritas Water Engineer, Prafulla Shrestha.

How do you find water?

FIRST
An assessment of the need for water is carried out. Criteria like the walking distance to a water source, the number of people relying on that water source, and time spent waiting at the water points are all taken into consideration.

SECOND
If the need is there, a geophysical assessment is carried out to find out where to dig or drill. Highly advanced technical equipment is used for this, and there is a 70 percent chance of success.

Different layers of stratum are defined. If the rocky layer continues, there is no water, but if there are cracks and/or layers of sand beneath the rocky layer, water can be found.

ACT/Caritas hires people from the Sudanese Ministry of Irrigation and Water Resources to conduct the geophysical investigation.

THIRD
The geophysical assessment will indicate where to dig or drill. If the aquifer (a layer under the ground where there is water) is missed by an inch, the team will not find water. So far, ACT/Caritas has had a success rate of more than 90 percent.
 
             
 
 

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.
 

A hand dug well or a borehole?

There is an upside and a downside to both solutions...

A well
On one hand, a hand dug well requires community participation. When it is built, many people have access to water at the same time. A well is sustainable, as it does not need major maintenance.

On the other hand, to dig a hand well is time consuming. It can take up to three months to dig a 14-meter deep well, and it is only possible to find water close to a wadi where there is water in the higher ground. The formation should not be too rocky, like in Garsilla, as it makes it too hard to dig.

Price: $2,500-$3,000 USD
for one shallow well

A Borehole
It is very fast to drill a borehole — one day. The quality of the water is better assured than the water in a well because the borehole is sealed.

The downside to drilling a borehole is that there is no community participation. A professional drill team does everything. If the yield of the borehole is good, a bladder can be set up that will allow many people access to water at the same time. If the yield only allows for hand pump, the access to the water is limited. A hand pump or a bladder is less sustainable, as it has to be maintained and needs technical skills for repairs.

Price: $9,000 USD

submersible pump, generator and bladder

Because of the magnitude of the crisis, ACT International and Caritas International have joined forces to respond to the ongoing humanitarian emergency in Sudan's Darfur Province. Both organizations are faith-based networks representing Protestant, Orthodox, and Catholic churches and their related agencies across the world.
