Toilets with a biogas/anaerobic digester

Here a few information concerning conection of the pipes from the toilets to the digester:
- route the 3 pipes from the toilet cubicles into one "inlet chamber" and from there with one pipe into the digester. With this you minimize possible leakage problems in the area of pipe-wall connection.
- if available take 4" pvc pipes (4 or 6kg/cm2) from the toilte cubicles to the inlet chamber. Give a slope of 1%.
- If available take a 6" (or 4") pvc pipe from the inlet chamber into the digester.
- make the pipe inlet into the digester below the water level in the digester to prevent gas leakage.
