Solar lighting
UCT will be researching the possibility of solar
lighting for these homes although electricity is available in many
areas thought out Africa this is a wonderful green alternative.
We are researching this option at the moment.
Pour-flush pit latrines
Pour-flush pit
latrines overcome the problems of flies, mosquitoes and odour
by having a pan with a water seal (a U-shaped conduit partly
filled with water) in the defecation hole. Excreta deposited
in the latrine pan is flushed by pouring 2 to 3 litres of
water into it. Water remains in the U-shaped conduit blocking
air flow and odour. The mixture is directed into a pit and
organic wastes are biodegraded. Sludge has to be regularly
emptied from the pit. The use of two adjoining pits alternately
enables the sludge in a full pit to undergo further decomposition
while the other pit is being used, and enables manual sludge
emptying after further sludge decomposition. More water percolates
through the soil surrounding the pit, and the potential for
groundwater pollution is higher. A pour flush toilet with
a pit is therefore not suitable when groundwater table is
close to the surface

Play Pumps www.waterforpeople.org
While children have fun spinning on the PlayPump
merry-go-round (1), clean water is pumped (2) from underground (3)
into a 2,500-liter tank (4), standing seven meters above the ground.
A simple tap (5) makes it easy for adults and children
to draw water. Excess water is diverted from the storage tank back
down into the borehole (6).
The water storage tank (7) provides a rare opportunity
to advertise in outlaying communities. All four sides of the tank
are leased as billboards, with two sides for consumer advertising
and the other two sides for health and educational messages. The
revenue generated by this unique model pays for pump maintenance.
The design of the PlayPump water system makes it
highly effective, easy to operate and very economical, keeping costs
and maintenance to an absolute minimum.
Capable of producing up to 1,400 liters of water
per hour at 16 rpm from a depth of 40 meters, it is effective up
to a depth of 100 meters.
UCT is researching the possibility of working in
partnership with Water For People to introduce this concept into
this new building development to being water to the PowerPlay Child
Care Centers and Child Care Homes within the complex.
