Locations: 1/ Beltabe; 2/ Deblong
Locality: Um Dukhun and Nertiti localities respectively.
State: Central Darfur
Conditions: the bidder should have:
- Valid registration certificate with the government of Sudan.
- Specialized in water-wells drilling industry with previous experience in similar technical and geographical areas.
- Have qualified technical staff, geologists, civil, drilling engineers, technicians, skilled labor etc.
- Have technical capacity, equipment including combined (rotary and hammer) drilling rig and devices required to carry out the water wells’ drilling and completion of work.
- Capable to use (if needed) both drilling methods (rotary and hammer) in each location.
- Should have financial capacity to start and complete the work on time.
- Should be aware of standards and policies of the Water and Environmental Sanitation Project’s (WES).
Scope of work:
Primary Functions:
Under the overall guidance and direct supervision of CRS and WES project Engineers, the vendor should bring and use his own drilling rig, equipment, devices, and materials and should complete the drilling of three boreholes at the specific points recommended by the geophysical survey as stated hereinafter with coordinates at each location.
The minimum diameter of the borehole is 6”, and inside diameter of uPVC casing and screens is 5.5”with suitable slot size range from (0.02” to 0.06” preferable 0.04”) depend of the aquifer grain size and sorting.
Based on the recommendation after pumping test results and the proved productivity, each well will be completed according to feasibility of one of the following two options (hand pump or water yard operated with submersible pump):
- After pumping test, if the water-well is productive but not feasible for installation of submersible pump, it should be equipped with hand pumps Indian Mark II, concrete apron, drainage, animal trough and fence. The work should be completed according to or exceeds WES technical Guidelines.
- Productive wells which are feasible and fit for operation with submersible pump should be completed as low-capacity (mini) water-yard comprises but not limited to:
- Water-tank, made of steel, cylindrical-shaped, with storage capacity of 10000 liters.
- The tank elevated on erected steel tower 5 meters height fabricated of iron beams.
- the water well to be equipped and pumped with electrical submersible pumps (size, head, and capacity, depend on pumping test results).
- Install discharge pipe to connect the pump with the elevated storage tank.
- Install distribution pipe to connect the elevated water-storage-tank to the distribution tabs and pipe work for community usage and filling of carts.
- Solar energy complete units with accessories including connecting cables, control panels, switches etc. to operate the submersible pump.
- Fencing the whole water yard with barbed wire and iron angles fixed into ground with cement-sand-gravel concrete, the main gate equipped with heavy-duty door made of steel.
- construct waste-water’s drainage from the distribution tabs.
- Any other addition(s) proposed by the vendor.
The vendor should submit quotations for both options (1 and 2), but the final settlement will be based on the selected option and the actual work done.
As option 2 require more specific data derived from pumping test, the bidder quotation for option 2 will be considered as a proposal that can be adjusted after the test.
The main objective of this work is to supply safe water supply to the health facilities and community of the target locations.
The geophysical survey recommended two specific points for each location option 1 and 2 in case of failure of drilling at point 1 the contractor should drill point 2; the following table summarize the recommendation:
