Design of Grey Water Treatment Using Community Soak Pit Method

The wastewater produced by homes is separated into two types grey water and black water, with grey water making up the majority of the flow. Grey water from residential apartments makes up 50–70%. Grey water’s composition varies widely depending on where it comes from (e.g., bathroom, laundry, or kitchen grey water), and it is affected by the local water quality. Preliminary data has been collected and surveying has been done for these selected village Honnakalasapura village with a population of 509. After surveying these villages, community soak pits are provided at the end of drainage points prior to mixing with black water. If any houses are not connected with drainage, then the individual soak pits are given for a particular house. Villages with Grey water pipelines that are directly connected with sanitary lines are the villages not considered for treatment. Reusing and Recycling of Grey water can be achieved by providing a community soak pit as well as individual soak pit. The design of the community soak pit is according to the population of village. Based on this 24.48 KLD greywater is produced per day. Based on this the diameter of the soak pit is given as 1.80 m, depth = 4.3 m and 7 numbers of rings are provided, the main aspect of this method is cost effective and easy to use.
