Processing performance of Communal WWTP is still low at this time. Communal WWTP performance evaluation is needed to determine the cause. Study was conducted on WWTP Tlogomas in Jalan Rona Tirta I Malang, which has the configuration of the processing unit that consist of Anaerobic Decomposer Tank, Phytoremediation Pond with water hyacinth and Filtration with the media of plastic bottles and glass bottles. Communal WWTP performance evaluation method using the method of measuring the level of the removal for BOD, COD, TSS, NO3, and PO4. Furthermore, the design parameters such as organic loading rate and residence time in the reactor was evaluated their feasibilityfrom related literature and design criteria. Evaluation results showed very low performance. Maximum processing performance 41.17% to 28.68% for COD and BOD. TSS removal level in the phytoremediation pond is quitegood (70.2%). While the level of maximum removal for a Nitrate is 28.14% on minimum flow. The level of maximum removal of Phosphates occur at maximum flow as big as 35.46%. Maximum performance of the filtration processing unit for BOD removal only reached 23.05% at the minimum flow. COD concentration at the outlet even increased. This low performance due to the low of the residence time (HRT) and organic loading rate (OLR). This condition is caused by lack of maintenance in the processing reactor unit. Efforts to improve theperformance of the WWTP are the intensive maintenance and the optimization of WWTP performance with the operating parameters among other are organic loading rate, hydraulic loading rate and residence time.
