Evaluation and Planning of Domestic Wastewater Management in Simokerto District

Simokerto District has 45 communal wastewater treatment plants (WWTPs), but they face several issues such as effluent not meeting quality standards, poorly maintained physical conditions, unsuitable designs, and residents not managing their domestic wastewater properly. Therefore, an evaluation and planning for future domestic wastewater management are needed. This study conducts evaluation and planning through the analysis of primary and secondary data. Primary data were collected through direct observation and interviews with Simokerto residents, covering the existing conditions of domestic wastewater management. The evaluation results indicate that the communal WWTP on Jalan Sidoyoso Wetan can still increase its service capacity by 238 people but requires a redesign with the addition of an equalization tank, pumps, and a disinfection unit. Meanwhile, the communal WWTP on Jalan Granting needs repairs for leakage, the construction of a dedicated domestic wastewater channel, and a redesign to enlarge the overall dimensions of the WWTP, including the addition of an equalization tank, pumps, and a disinfection unit.
