Organic Wastewater-Grey Water Management In The Residential Area

Abstract

Grey Water wastewater in residential areas near Gisik Cemandi river has a COD value range of 146 – 516 Mg / L and the BOD value is in the range of 76 – 280 Mg / L. While Gisik Cemandi River is included in Class III rivers with COD values of 22 – 31 Mg / L. For the water quality of the Gisik Cemandi river to be maintained and not go down, the residential area must have structured Grey Water wastewater management. The management needed is technical, institutional, and financial management. Technical management planning is carried out by providing recommendations so that residential area has management activities in the form of maintenance and repair by adjusting the available facilities and infrastructure. In addition, a Wastewater Treatment Plant is needed that is used for biological treatment because the BOD/COD ratio of Residential Grey Water is 0.528 or biodegradable. Biological processing of gray water can utilize plants as BOD and COD reducers. In carrying out technical management, it is necessary to have institutional management as a monitoring role between implementers and citizens. The recommendation of institutional management is to be able to follow the institutional practical guidance of the Ministry of Public Works. All technical and institutional management activities require financial management as capital in every implementation of Grey Water organic wastewater management in residential areas. Financial management calculations must be adjusted to regional regulations and calculated for the next few years by considering the value of inflation.
