Design and Detailing of a Waste Water Treatment Plant for a Small Community

Abstract

The water supplied to a community receives a range of chemical substances and microbial flora during its use such that the waste water acquires a polluting potential and becomes a health and environmental hazard. Communicable diseases of the intestinal tract such as; cholera, typhoid, dysenteries and water borne diseases like infectious hepatitis etc. can be spread from uncontrolled disposal of waste water and therefore, prevention of communicable diseases and protecting public health attracts the primary objective of sanitary waste water disposal. Little is known about the viability of WWTP. Therefore this research paper has been undertaken to provide a comprehensive study to establish guidelines for their application. In the context it is not pre-requisite to find the best sanitation technology for a given problem but to list the conditions where WWTP represents an efficient alternative to either conventional sewage or on-site wastewater treatment/disposal technologies. Design and detailing of such a waste water treatment plant has been undertaken to avoid a breach of polluting environment for a small community of 7000 people approximately.
