Pipelines:

Pipelines need to be laid: a supply line to convey water from borehole in Infiltration Gallery to the storage reservoir and distribution line to take the water from storage reservoir to the distribution points.

The pipeline needs to be protected to ensure a lifespan of 20 – years. Recommendations for laying pipelines include:-

  1. Preparing the trench: the nature of the ground will determine the choice of flexible or rigid jointed pipes .Flexible joints are preferred to rigid joints to allow for settlement which is likely .It is very important to ensure the alignment and bottoming up of the trench .Larges stone must be removed from the bed of the trench.
  2. Back filling all the trenches in hard formation need to be backed filled with 200 mm of sand or any soft materials especially where the ground is stony, the materials of the back filling must be soft and cannot contained lumps of rock or large stones .The pipe should be covered with a minimum cover of soft materials.
  3. Handling and laying of pipes: pipes must be handled with rope slings to preserve to protective coating and prevent puncturing which could lead to corrosion. Care must be taken, to ensure that the pipe ends ratline their circular shape. Upon delivery, every pipe must be inspected and rechecked before it is lowered into the trench.
  4. Testing pipes: Pipeline should be tested in reasonable length leaving the joints exposed to view. The test involves filling the pipeline with water under pressure, which exerts pressure of about 50% in excess of the working pressure. it could also be of extra pressure of known value say 30m to 50 water head

Galvanized iron (GI) Pipes

GI are usually supplied with tapered threads at the ends with one straight connector per pipe. It is preferable to cut the pipe to length with a pipe cutter rather than hacksaw.

To enable pipes and fittings to be removed for repair, threaded GI pipes should be joined with screwed unions on at least one side of a valve or fitting and in long length (>100m) GI pipes have flinched joints . Flinch dimensions can vary widely so new fitting must be carefully matched to existing pipe work. Ensure that there are sufficient gaskets for each flange joint. GI pipes can be welded, but this should be reserved for critical joints and for making up adaptors and special fitting.

Firmly anchor exposed GI pipes using pipe anchors of steel and concrete .Exposed empty GI pipes can became very hot in a warm and sunny climate. Care must be taken when filling hot pipes with cold water as the sudden contraction can damage threaded joints causing them to leak.

The following precautions should be taken when handling and storing GI pipes:

  • Protect the threads in transit and when loading and unloading as they can be easily damaged. A new GI pipe is normally bundled with a straight connector on one end and thread protector on the other
  • In transit ensure connectors are firmly screwed on each pipe as they can vibrate loose.
  • In hot, sunny conditions, store a GI pipe under cover as pipe may become too hot to handle.

Installation of submersible pump unit:

 

  • The contractor will be responsible for providing expert Engineers and technicians for installing submersible pump.
  • The contractor shall Provide and check truck Crane and all accessories before installing submersible pump unit in suitable depth, based on the attached pumping test report and the materials should be test before installing.
  • The contractor shall secure the Borehole after installing submersible pump unit by covering the top of well.
  • The contractor provides on-going report engineering support through completion of the Work.

Construction of distribution point:

 

  • Distribution point should be able to accommodate Um Koaro water users, humans, and small livestock. Arrangement of all these to distribution points should facilitate water collection for the users and water supply provider. Distribution points are demonstrated.
  • Maxing ratio of concrete according to BS.
  • The contractor should construct one water stand for humans with wall and concrete slap and raised at 1.0 m wall with 10 taps I inch, 5 taps in each side with high quality according to attached BOQ and direction of site engineer.
  • The contractor shall install a drainage system and plain concrete around water distribution points if needed.

 

Installation of solar system:

 

  • The contractor shall provide a total of xx Solar PV-Module poly crystalline of 180 -200 Watts, or equivalent to the total power demand with junction box. The panel should have a period of warranty of up to 10 years.
  • The contractor should provide inverters with good quality and warranty for at least 2 years.
  • The solar panels should be placed, and spot welded in an elevated position with a height of at least 4- 5m of the generator room to avoid stealing and damaging using beams 14 mm and heavy angles, 15-tilt angle with high stand and high wind speed (50km/h) the support fixed into line.

 

Construction of the Generator room and fencing:

  • Size 3x3x2.5, the contractor shall fabricate and install 2 windows made with both expanded good quality metal and 30-gauge zinc sheet. The generator room should have one steel door and plain concrete floor (1:2:4) 10 cm thick. The room should be constructed for simple assembling and dismantling, and the generator should place on foundation 20 cm above the floor level.
  • The solar panels should be in the top of the generator room according to BOQ and instruction of site engineer.
  • The contractor should ensure that the generator room would be able to carry the loads of the solar panels stands, using beams on the four angles and heavy angle for solar panels stand.
