Organic
Latrines A great many of the
solutions to the clean water and personal hygiene
issues facing rural Cambodians require hardware to
facilitate their implementation. RDI is actively
involved in the process by both designing and building
much of the needed equipment and structures.
For example, simple and effective organic latrines
are being built at homes that have previously had
no method of waste disposal available. These
latrines consist of two cylindrical holes. One
hole is the active side, the other remains unused
for a time. A rectangular concrete base is placed
over the active hole. In order
to keep costs down, the base has no walls but is fitted
with four PVC pipes from which modesty screens can
be hung. A lid to reduce ambient odor and insect
attraction is also provided. A family can use
this active side - being careful to sprinkle ash into
the hole after each use - until it is filled (about
18 months.) At that time, the base is moved
over the other hole which now becomes active.
A round concrete lid is placed over the exposed hole
and the contents are allowed to compost into usable
fertilizer. When the second hole becomes filled,
the process is reversed.
