Abstract

The village of Mekar Rahayu was selected as the site for the design of a wastewater treatment plant in Margaasih District. This sub-district is located in the Citarum River Basin, which does not yet have a domestic wastewater management system. Domestic wastewater is discharged into septic tanks or into drainage canals, which eventually ends up in rivers. This requires efforts to plan a domestic wastewater management system, considering that the domestic sector is the largest contributor to the pollution load in the Citarum River. The aim of this research is to determine an appropriate domestic wastewater management system to be implemented in the village of Mekar Rahayu. The research method is field observation and planning with reference to the regulations in force in Indonesia. The results of the research on local communal wastewater management systems can be applied in this region.  It is planned that 2 future community wastewater treatment plants will serve 25 out of 28 community units in this sub-district. 3 communes that do not fall within the service area of the treatment plant because the settlements are small and dominated by agricultural land, so they can still use the local system.  The calculation results for the total domestic wastewater generation are 118.16 litres/second. Based on the analysis of land requirements, ease of operation and other things, the selected series of domestic wastewater treatment plants are bar screen units, collection tanks, grit chambers, equilibration ponds, activated sludge, sedimentation II and disinfection.

Abstract

The construction of a wastewater treatment plant (WWTP) in Sayati Village is still required in order to dispose of the village's wastewater in an appropriate manner. One potential location for wastewater disposal is the Cikahayangan River. However, the discharge of sewage into the Cikahayangan River results in water pollution, which in turn disrupts the river's natural functions. It is imperative that Sayati Village devise a WWTP that can effectively and efficiently treat wastewater, while also adapting to the existing conditions of the village over the next few years. This is crucial to prevent any adverse impacts from water pollution. The BOD/COD ratio for Sayati Village is 0.809, indicating that the wastewater is treated biologically. The unit selected from the scoring method is activated sludge. However, the land available in Sayati Village is limited, so the WWTP unit refers to the 2022 Sanimas Technical Instructions, which describe a compact WWTP for 100 families with a land availability of 3 meters in width. The domestic wastewater treatment plant (WWTP) processing unit planned for Sayati Village, Margahayu District, consists of primary, secondary, and tertiary domestic processing units. The secondary processing unit selected is an anaerobic filter, which is in accordance with the 2022 Sanimas Technical Guidelines. The units that will be planned in Sayati Village are a bar screen, a grease trap, a screw pump, a grit chamber, an equalization tank, an anaerobic filter, a disinfection unit, and a sludge processing unit.

Abstract

Soreang District is the capital of Bandung Regency, with a population that continues to grow due to infrastructure development. This area falls within the Citarum River basin. The domestic sector is the largest contributor of pollutants to this river.  This area already has a wastewater treatment plant, which was built in 1991. The aim of this research is to evaluate the capacity of the constructed WWTP in order to determine whether or not it is still able to cope with the wastewater produced. The methods used are field observation, measurement and comparison with current design criteria. Based on the research results, the existing plant can only serve 250 heads of families. It is necessary to increase the capacity of the plant to cater for the growing population. The current condition of the plant is sub-optimal due to plant maintenance issues. In addition, the sewerage network is damaged and there are no experts available to operate the plant. The research findings call for efforts to rehabilitate existing wastewater treatment plants and increase their capacity. Domestic wastewater treatment will reduce the pollution load of the Citarum River.
