In Asemrowo sub-district 89.6% of the community has a private latrine. This article attempts to design a domestic sewage and wastewater treatment plant in Asemrowo District based on Surabaya City Regulation Number 12 of 2016 concerning Water Quality Management and Wastewater Control.

The processes of the design includes acquiring primary data from field observations, distributing community questionnaires with random sampling of 105 respondents and analyzing the quality of wastewater for references in the wastewater treatment plant (WWTP) design. The domestic wastewater distribution system uses Shallow Sewerage which is divided into 4 blocks. The diameter of the wastewater pipe used in this plan is 114 mm, 140 mm, 216 mm and 267 mm. WWTP used in blocks A, B and C use Aerobic Biofilter and Clarifier. As for WWTP block D, it uses Aerobic Biofilter.
