MODELLING AND VALIDATION OF A SEWERAGE SYSTEM WITH ON-SITE SEGREGATION AND TREATMENT FOR WATER SHORT HABITATIONS IN DEVELOPING COUNTRIES

Shri. M. Dhinadhayalan Dr. A.K. Nema

Abstract

The practice of piped sewer collection is basically an inheritance from advanced countries with high water usages at about 350 - 400 liters per capita per day (lpcd) which ensures adequate flushing velocities and do not result in night-soil lumps settling down in pipes and do not result in choking and sulphide gas generation whereas in the Indian scenario, the lpcd is just about 70 - 100 and that too intermittent and this results in the said, settling down of night-soil, choking, gasification etc which necessitates very often the extreme remedies of cutting open the roads to access and break open the pipes and rectification etc. This further necessitates the need to approach the decentralized sewerage system with a possibility of solubilizing of the night soil by appropriate on-site treatment before its collection and conveyance
