Funded by Central Government, Local Government,

Community and BORDA

Approach for Implementation Consulting—supervision

Executing Agency DEWATS-LPTP

Supporting Organisations

Client Islamic Centre An Nawawi Location Indonesia; Central Java Province, Purworejo,

Technical Description

Treatment capacity 35,8 m3

Technical components - WWTP-communal system con-tained of : Inlet (V= 0,2 m3), Di-gester (V= 24,07 m3 ), expansion (V= 9,03 m3 ), Sedimentation (V= 19,5 m3 ), anaerobic baffle reactor (V= 70,2 m3 ) and expan-sion chamber (V= 23,4 m3 ) which consisting of 7 compart-ments. The effluent is discharged into river/ water body.
