Provide a locked access to the pump with 2 sets of keys. Provide a manual pump option to the well if the electric pump fails. New wells must be

11-Feb-21 Page 16 of 55 located a minimum of 30 m, but 50 m is preferable, from all septic systems or pit latrines.

To provide a reliable pressure and flow rate to the building, provide an elevated water tank between the well and the building. Provide a water storage tank size and elevation for the operational requirements of the facility. Tanks must be designed, fabricated and constructed for drinking water use. The water tank and piping must be UV resistant and include appropriate features (i.e. shading, insulation) to ensure water temperatures stay at an acceptable level for facility use. The water tank must have the ability to be filled by truck delivery, and include an access ladder and man-way for interior access for cleaning. The location of the fill connection must be convenient and labeled. The fill point and cleaning access must be secured and locked.
