Refer to drawing of typical tank
installation.
The solar pumps pump water from the wells to the various water points
(tanks) near to the users' houses. The chosen pumps can easily transport the
water for several kilometres from the wells to the water tanks through
polyethylene pipelines. The above-ground tanks will each have a capacity large
enough for three days' water for the community to which they are dedicated.
Back-up hand pump systems will also be available at the well sites in case of
need. The water in the tanks at schools and clinics will be purified using ultraviolet
solar purification units. Water purification can be extended to other community
supply tanks at a later stage of the project. The water tanks will be fitted
with double stainless steel ball valve sets. The ground surface at the water
points will laid with shingle and kept dry so that the users' feet always
remain dry. A sink-pit with stones and shingle will be used to drain any spill
water. The tanks will be made locally from gypsum composite materials.
List
of drinking water requirements.
The assessment of drinking water requirements is carried out on the
basis of an average distance not exceeding 10-200 meters between each home and
a drinking water point. A basic drinking water supply of at least 25 litres per
person per day is foreseen. A further 25 litres per person per day is usually
made available as a back-up at protected boreholes and wells, which are placed further away. The project also provides for domestic
rainwater harvesting systems designed to supply an extra 25 litres per person
per day of non-potable water for personal uses such as washing and cleaning.
Water is not required for sanitation purposes, as dry composting eco-sanitation
toilet systems are expected to be used.
