SPATIAL MAPPING OF WATER SUPPLY & DISTRIBUTION NETWORK OF KCAET CAMPUS USING TOTAL STATION SURVEY & GIS

Abstract

Water supply and distribution system conveys water from source to different outlets. For the ease of handling, maintenance and other services mapping of water supply and distribution network of KCAET campus is done. The study focuses on mapping using on GIS, GPS and Total Station. Through reconnaissance survey two major sources intake well and open well near the farm were identified. The hostels in the campus are supplied by intake well after filtering through slow sand filter. Rest of the area is supplied by open well near farm house. After making an index sketch from reconnaissance survey, Total Station survey was carried out to locate all the points of the water supply and distribution system in the field. The survey started from north - west part of the campus and finished at north-east part. The Total Station data was exported to ArcGIS 10.7 for mapping. Different thematic layers such as supply lines, distribution and service lines, valves, buildings roads and boundary were prepared. These thematic maps were overlaid for preparing the map of Water Supply and Distribution Network. The capacity of overhead tank was identified as 75000 L and of the slow sand filter was 150-200 L/hr. The open well near the farm office was found as 1,30,000 liters per day. The spatial map of the Water Supply and Distribution System of KCAET Campus can give proper information and pattern of supply and distribution network. Further it forms a reference for future expansion works of the network.
