Due to explosive urbanization in Bangkok, it was realized that it would be difficult to adapt the conventional sewerage system to cope with the increased load. It was more feasible to collect wastewater by the existing drains and to adopt a modified aeration method for treatment of typical municipal wastewater, namely effluent from on-site septic tanks. An experimental test plant was constructed to evaluate the treatability of municipal wastewater generated from the major drainage area, in comparison with that of conventional wastewater from a new community with a separate sewer system. The results verified the higher treatability of the municipal wastewater compared to the communal wastewater with respect to effluent water quality, settleability of mixed liquor, solids production, etc.
