The lack of domestic wastewater management services in the Cibabat River Basin has resulted in the Cibabat River being a place to collect domestic wastewater. This of course can reduce water quality  as well as reduce the function of the river itself.  The Cibabat river is known to be a sub-watershed of the Citarum River with a surface   area of  1,855 km2. Activities in the Cibabat watershed  contribute  to the pollution load that  causes the water quality of the Cibabat River to decline, which of course has an impact on the decrease  in the quality of the river and increase  in the polluting  load that the river will receive. The research method uses the calculation of the pollutant  load based on Permen LH 115/2003. The data used are  secondary data from DLH Cimahi City, which  conducted a water quality analysis at three points during  three different seasons in 2019. One of the steps to overcome and control the pollution that occurs is to determine the actual pollutant load so that it can easily determine the application of effective technology  for controlling river water pollution  in the Cibabat River at theCimahi City.

The increase in population causes the need for clean water and community activities to increase and has an impact on increasing the amount of waste water produced. The amount of waste water that is generated depends on the large number of the population on the need for clean water used in every existing human activity. Domestic waste management in the Cibabat watershed area, Cimahi City is still minimal, in an effort to improve the quality of the Cibabat river and support the acceleration of pollution control in the Citarum watershed which is part of the Citarum Harum program in 2018, so a planning system for the distribution of domestic wastewater is needed Cibabat watershed, Cimahi City with the aim of producing domestic waste water that can be channeled and treated properly so that it does not pollute the aquatic environment. The method used in the planning of the domestic wastewater distribution system refers to the PUPR Regulation No. 04 of 2017 concerning guidelines for the implementation of the domestic wastewater management system. With the wastewater distribution system in the Cibabat watershed, it is hoped that it can improve the quality of water in the Cibabat River, Cimahi City in the planning period of the next 20 years. This study will determine the type of application of an effective domestic wastewater management system adapted to the existing conditions of the Cibabat watershed, Cimahi City.
