Abstract
The Junagadh Agricultural University campus is located in Junagadh, which lies in western Gujarat. The human population on the campus is multiplied distinctively due to the establishment of new schools and hostels.The university campus had a population of 1418 in the year 2013 when the supply of water was 152 lit/day per person and the sewage generation was 0.0084 m3/s (725.76 m3/day).Hence, a sewage treatment plant (STP) with suitable capacity is needed to deal with the elevated sewage. The recycled water can be utilized for agricultural purposes. This paper discusses about the design of STP and its major components such as skimming, grit chamber, and screening chamber, active sludge, sedimentation tank and secondary clarifier in the end sludge drying beds. The proposed design is suitable for 0.0672 m3/s sewage and would help to provide58 MLD process capacity. In the end, treated water will have been used for irrigation purpose in the research field of a university.

Materials and Methods Location of Sewage Treatment Plant (STP) Sewage treatment plant must be placed as near the land at such an area from wherein the dealt with sewage can immediately go with the flow under gravitational force closer to the disposal factor
Summary
Water is one of the important and precious natural resources. Efficient use of water is important for agricultural production. Treated sewage water is rich both in organic matter and nutrients which fulfil the requirement of plants ( phosphorus and potash). It's far estimated that the projected wastewater from the urban area may pass 1,20,000 MLD via 2051 and that rural India will even generate not less than 50,000 MLD on the basis of water supply designs for community components in rural regions (see table 2). That means one receiver chamber is required for collecting 24 hr sewage discharge in that way plant is run in two shifts of 1.5 hr in a day.[7] Proposal site for STP in JAU has shown in fig.[1]
