Abstract

Sidayu District is one of the 7 Districts that have not been served by PDAM Giri Tirta Gresik. Mirza's research results, 2022 stated that the groundwater in Sukorejo Village, Sidayu District was moderately to heavily polluted. Therefore, it is necessary to plan a drinking water supply system so that the people of Sidayu District can enjoy clean water. The purpose of this study is to plan a clean water supply system in Sidayu District and calculate the Bill of Quantity (BOQ) and Budget Plan (RAB) in planning the SPAM network distribution system in Sidayu District, Gresik Regency. This planning methodology uses quantitative methods. The quantitative method is a type of research that is structured, planned, and systematically clear from the start to the creation of the research design. SPAM planning in Sidayu Sub-District flows through the villages of Raci Tengah, Asempapak, Bunderan, Kauman, Sidomulyo, Purwodadi, Srowo and Lasem. The raw water source comes from the Gerak Sembayat Dam, so the reservoir is located in Melirang Village, Bungah. The total need for clean water is 197.85 liters/second. The total Junction is 842. So that the air does not experience negative pressure, 2 reservoirs are added so that there are 3 reservoirs with 3 pumps. The output head on pump 1 is 50 meters, with a flow of 197.85 l/s, the head output on pump 2 is 50 meters, with a flow of 68.77 l/s and the output head of pump 3 is 50 meters, with a flow of 14.30 l /s so that water can be served up to the customer. The bill of quantity needed for planning a drinking water supply system in Sidayu District, Gresik Regency, namely the volume of land surface cleaning and stripping is 11,859.953 m2., The volume of excavation is 10,897.64 m3. , the volume of sand filling was 4,430.50 m3., the volume of backfilling was 5,101.543 m3., the pipe length was 21,022.1 m, the pipe accessories were 26 pieces. The total budget plan required for the development of the drinking water supply system for the villages of Betro, Wedi and Ketajen is IDR 49.398.746.460.
