Wait and see
Fresh faeces is building up. The pit looks too wet, but it looks
recent rather than chronic, as there appears to be
vermicompost, which means that the pit has been working
well. This could be a case of water infiltration after rains or high
water table. Monitor in 1-3 weeks (depending on rain) to see if
the pit is drying and fresh faeces reducing. Empty if the faeces
reaches the pipe.
OK, Ensure a proper pit seal
Vermicompost around the edges shows that the pit is
functioning. Fresh faeces appears to be building up a little.
Check again in 1-3 weeks (depending on rain) if the amount
of fresh faeces is reducing. The cockroaches are not harmful
for the worms, but if the pit is not well sealed, they can leave
and transmit diseases. Make sure the pit and latrine are well
sealed.
OK
Coconut husk bedding layer. Fresh faeces in the centre, around
15% coverage. Vermicompost appears to be building up
around the edges and looks like dark, bobbly soil. This pit is
working well.
OK
Looks ok. Fresh faeces building up a bit. Check under dark
surface around edges. Looks like vermicompost, but if bright
colour under the surface, then it is fresh faeces.
