The Junagadh Agricultural University is located in south-west of Junagadh city, Gujarat. The population within the campus is increased by virtue of establishment of new colleges and new hostel. But still now there is no Sewage treatment plant. So it is required to construct a Sewage Treatment Plant with sufficient capacity to treat the increased sewage and recycle the water for the agricultural purpose, it is also required to provide septic tank at each building unit with enough capacity and intergrade these septic tanks with properly designed drainage network which leads to proposed STP.
