composting area, a concrete open channel is constructed. The longitudinal slope 

of the channel is 0.20%. The channel has a rectangular cross section with a 

variable depth that increase in the direction of the slope (towards the north). At 

the end of the channel a manhole a rectangular manhole covered with concrete 

aluminum gratings. At the outlet of this manhole, a PVC pipe is to be constructed 

to connect the composting area drainage system to the thickener supernatant 

back flow pump. The mixing area is drained using a rectangular manhole 

constructed at the middle of the concrete floor. 




The manhole is covered with aluminum gratings. At the outlet of this manhole, a 

PVC pipe is to be constructed to connect the mixing area to the drainage open 

channel of the composting.
