Incorporating
innovative social, financial, economic, local administrative and productive
structures, numerous renewable energy applications, with an important role for
women in poverty alleviation in rural and poor urban environments.

Edition 10:
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.
