In this modern world of advanced techniques, sewage treatment works are considered to be one of the most popular procedures carried out to use the treated wastewater for agricultural purposes or to dispose off on to the land. The primary objective of this study is to design a Sewage Treatment System for Sri Satya Sai Urban Development Authority (SUDA) in Andhra Pradesh and studying the possibilities for usage of treated wastewater for irrigation. The study area, Puttaparthy being a pilgrim center attracts people all over the world and during some special occasions the place gets over crowded. Hence, sewage treatment units were designed specially keeping in view of the peak population. In the present study, design of the various sewage treatment units like screens, grit chambers, primary settling tanks, trickling filters, secondary settling tanks, sludge digestion tanks, sludge drying beds were carried out. Puttaparthy and its surrounding areas come under drought prone areas of Anantapur district. Hence large numbers of people are migrating for works due to lack of irrigation water for growing of crops. Hence, the treated wastewater of SUDA can be used effectively for raising some suitable crops in that area. The National Water Policy of India also emphasizes the need for recycling and reuse of wastewater.
