Practical Action
barrels.
Add some engine oil to the pit. By doing this the rusting of the barrels can be reduced
and help to avoid mosquitoes breeding.
By adding a weight on top of the barrel, the pressure
can be increased.
By applying a coat of paint
every six months, the
barrels can be used for a
longer time.
The maintenance and the use of the other pipe
system and the other equipment should also be
done in the same manner.
In removing the waste….
It is best to collect the new raw material before
removing the old waste material (then the gas can be re-
obtained very quickly).
Open the lid of the digester; this can be kept open for about
two to three days.
Afterwards remove all the
waste from the pit.
The black water, which is
in the bottom of the pit,
can be collected and used
as a fertiliser and a
pesticide.
Now refill the pit.
