1 Executive Summary

BFD funded by UNICEF implemented Water and Solar Energy Projects in Al Marashi

District, Al Jawf Gov. In which water networks were installed with a length of 23,883 m,

and an elevated reservoir 100 M 3 as well as control room were constructed. Moreover,

solar panels 40,960 Watt were installed in order to help to operate the process of

transforming water from the borehole to the elevated reservoir. All in all, these

implemented components relieved Al Marashi householders from the suffering, family

hardship, and strife of walking far distances to provide daily water sustenance in small

buckets, pans, and plastic jerry cans.

5.1 FIELD VISITS

On Sep 5th, 2018, BFD's engineers descended to the project site in order to figure out all

the details of the borehole status, surrounding boreholes and any other obstacles that may

happen during the implementation. They found that the borehole is with no infrastructure,

and no consumption; moreover, it was closed by a tree trunk for a very long while.

5.3 CLEANING THE BOREHOLE

On Jan 7th, 2019, a rotary digger (T4W), as well as a Volvo truck were sent scarcely to Al-

Marashi District in order to clean and save the borehole. 13 pipes were lowered into the

borehole, each pipe has a length of 7.6 m, which means the whole 13 pipes have a length

of 99 m, where the obstacle is located. The pressure of the rig was placed at 150 rpm,

followed by the pressure of the air on the waste from the cleaning work to the outside of

the borehole. The excavator continued to reach a distance of 170 m; yet, it was stopped

at this distance and the cleaning was continued at 150 rpm for 3 hours. The foam helped

to facilitate the process of removing the sediments.

5.4 PUMPING TEST

On Jan 10th, 2019, BFD handed over the site of the project to the contractor in order to

commence conducting the pumping test. The pumping test was carried out in two stages,

the first step was a step-drawdown test; whereas, the other one was a constant pumping

test. The pumping test lasted for 5 days in a row, and according to it, the borehole yield

was determined to be 12 liters / s.

1) The step-drawdown test

The step-drawdown test consisted of three steps, with each consecutive step being

pumped at a higher rate than the previous step. The total pumping of the three steps lasted

270 min, with each step lasting for 90 min. The 270-minute stress test commenced

immediately after the conclusion of the step-drawdown test.

2) The constant pumping test

The static water level was measured at (51.6m), and then the constant pumping test was

carried out. The final step approached the estimated maximum yield of the borehole which

is 12 l / s. As the pumping process continued, there was a gradual decrease in both water

and productivity levels. The water dropped to 100 m after 10 hours with the drop-in

productivity to 12.50 l / s after 16 hours of pumping. Both the level and yield were

sustainable at 103 m; in addition, the yield was 11.80 l / s until the end of the 30-hour

continuous pumping process.

Recovery Test

The constant pumping test was stopped, and a recovery test was conducted. It was

observed that the water returned to the static level (51.6 m) after 11 hours of stopped

pumping.

5.5 IMPLEMENTATION

1- On Mar 31st, 2019, BFD handed over the project site to the contractor in order to commence

implementing the work of the water project, in which an elevated reservoir and a control

room were constructed. Moreover, water network lines have been installed, and a wall for

the solar panels was built.

2- On Jun 24th, 2019, BFD handed over the project site to the contractor in order to commence

implementing the work of the Pumping Solar Energy Project, in which a complete pumping

solar energy was installed.

5.6 HAND OVER THE PROJECT SITE

On Oct 1st, 2019, BFD handed over the project site to the committee of bens of Al Dhalah

Project in order to look after it and make sure that the water is pumping to each HH in the

district. The site was handed over to the committee of bens in the presence of the Director

of GARWP, Director of the District, and engineers from Al Jawf governorate Office.

6 Challenges / Issues and Solutions Taken

Challenges / Issues Solutions Taken

Demanding the Chairman of the Beneficiary Committee to increase the productivity of the pump as well as increase the number of panels.

A committee was set up to investigate this problem, and it was proven that the yield of water is 11 liters per day to each HH in the district, which means that the pump covers triple the daily production of water.

The borehole casings are corroded, making the water pretty much salty; besides, the ruined casings let the dust fall and fill the borehole.

Using Borehole's camera to check up the borehole and evaluate the damage in the casing after extracting all the pipes from the borehole; furthermore, renting a drilling rig to dig the borehole for almost 150 meters depth, then replacing all the damaged casings, and the final step would be the pumping test.

The coverage of the internet is very weak in Al Jawf; as a result, BFD team encounter difficulties in sending daily, weekly and monthly reports.

BFD team travel from Al Jawf to Sana'a to submit reports, and sometimes they send them to Sana'a by cars that belong to the foundation.

During the excavation of the water network lines, BFD team did not know that there was a telephone network underground, which destroyed the telephone network during the excavation.

BFD repaired the telephone network, which cost $ 3500.

The difficult terrain of the district as well as overlap and high density of HHs, which made it difficult to identify the paths.

Divided the district into squares and made a sketch for each square which shows all the HHs.

7 Lessons Learned

• Before excavating the ground, asking the residents whether there is a telephone network

or not. In case there is, asking about the places of them is a must.

• Avoid engaging with contractors who have limited resources.

Without complementary components, the project will not be sustainable. For example,

rehabilitating boreholes will make no difference to health if community members are not

educated on the benefits of using clean water and maintaining the water systems.

• It is necessary to count all the houses in the target district accurately.

8 Recommendations

It is recommended that:

• When conducting the population census, never ever forget taking with you the chairman of

bens to make sure that all the houses and residents in the district have been counted.

• Carrying out regular field visits to the project site after finishing the implementation and

handing over the project site to the bens.

• An inspection of the borehole should be carried out every 2 years to confirm that its

condition has not altered in the preceding years.

• Further to the elevated reservoirs, it is recommended to distribute small tanks to each HH

in the target area.

Cleaning and Rehabilitating a Borehole Save Thousands of Lives

“Is it possible to conduct a project on a mountain, and how would you rehabilitate that closed borehole by a tree

trunk?” Ahmed Salah said, a fifty-seven-year-old man who resides in Al Dhalah Village. When it comes to humanity,

everything becomes possible, period. Human lives are more important than anything else. For vulnerable and

conflict-affected populations residing in Al Dhalah Village, Al Marashi District, Al Jawf Governorate, access to safe

drinking water often requires long, arduous hours of walking to the nearest borehole; and what is more, the village is

situated in a mountain, 50-meter-high above the ground level. The worst part of this, is the world’s largest acute

watery diarrhea/ suspected cholera outbreaks caused by contaminated water, especially in Yemen including Al Jawf

Gov. “There are 56 cholera cases, and what makes me happy now is that the residents of Al Marashi District are

aware of the danger of cholera which caused by unclean water.” Dr. Amar Ali said, one of the doctors at Al Marashi

Health Center.

BFD (Building Foundation for Development) funded by UNICEF knew that implementing the project will take a

supreme effort. “We found that the borehole is with no infrastructure; moreover, it was closed by a tree trunk for a

very long while.” Abdusalam Al-Asad said, one of BFD’s engineers (WaSH Officer). He also added saying, “The

issue is not how to clean and carry out the pumping test on that borehole, but how can a rotary digger (T4W), as well

as a Volvo Truck reach the project site, especially the borehole?” Therefore, many meetings were held to come up

with solutions, and hopefully, all WaSH staff were determined to implement that project. “No matter how much does

it cost, and no matter how long time does it take, the project must be implemented to help the residents of Al Dhalah

Village.” Ahmed Al-Theeb said, the program manager of BFD. He added saying, “If a Pressure Digger cannot reach

that site, I myself and all BFD staff will travel to Al Dhalah Village and clean the borehole ourselves to help those

in a dire need for clean water and to end the outbreak of cholera.”

“Yes, BFD faced difficulties in taking permissions to let the Rotary Pressure Digger enters to the project site since

the project is situated in a conflict-affected area and the Saudi-led coalition aircrafts might carry out raids on that the

Rotary Pressure Digger, thinking that it is a launching pad of missiles.” Mohammed Al-Sanabani said, the project

manager of WaSH Sector. He added saying, “Despite the challenges that BFD encountered, the project was

implemented fruitfully, in which an elevated reservoir 100 m was constructed, water networks with a length of 23883

m were installed, solar energy system 40960 W was installed. Moreover, a control room, as well as a wall for the

solar panels, were built.” Currently, 3448 the populations of Al Dhalah Village do not need to walk long distances

to collect water since they have easy access to clean water for drinking, cooking, and cleaning. On the whole, the

intervention of BFD ensured clean water provision to host communities and IDPs with quantities no less than 15L

per person, which rest assured them that the outbreak of cholera has been reduced due to the clean water.
