Repair and Rehabilitation Procedures 

 

For installing or dismantling a borehole, at least two trained people are required to oversee 

and guide the unskilled labour  force. The technicians should ensure that they have a  com-

plete tool box with all the required tools for installing / dismantling including an extension 
rod of about 30-50cm length.  
Various steps and tools are used for each step as illustrated in the  U2-installation manual, 
which is expected to be in the training package (and beyond the scope of this training). 

 

The Roles of the Water User Committee in ensuring the functionality of 

the Water Point 

 



Mobilize 

community members to participate in water source protection e.g .   Building 

the fence, and regular cleaning of the surrounding. 



 Keep an updated list of the 

water users 

in the community. 



 Collect and keep contributions towards the construction cost and the O&M funds 



 Regularly 

visit and monitor 

the condition and performance of the water point 



 

Verification 

of the purchase of materials needed for the repair or maintenance of the 

water  source. 



 

Pay 

for any repairs carried out by  a mason or hand pump mechanic. 



 Supervise and provide 

support 

to the water source caretakers. 

 

       The Roles of the Caretakers 

 

Show people how to use the water point properly 

  Carry out regular maintenance of the water point e.g. sweeping and slashing around 

the borehole. 

  Keeping record of all the maintenance work carried out on the source either directly 

 

by the caretaker 

or by a  (HPM) Hand Pump Mechanic,  plumber or mason. 

  Mobilize  community  members  to  participate  in  maintenance  activities  e.g  regular 

 

cleaning of   the surrounding of the water source,  advice the community on regular 

cleaning of containers both for  storage and collection.
