Study on Drinking Water Distribution System at Sekaran District Service Area in Lamongan Regency

Drinking Water Supply System (SPAM) organizers needs to carry out its duties and functions to fulfil the quality, quantity, and continuity for the community. From all SPAM service areas in Sekaran District, there are three villages, namely Manyar, Jugo, and Trosono Village which lack access to water. The three villages water pressure falls below the minimum pressure requirements of Minister of Public Works and Housing Regulation Number 27/RT/M/2016. Seeing that the continuity is not optimal, it is important to study the drinking water distribution network of one of the SPAM in District Sekaran service areas. Recommendations for pipeline network restoration involves conducting hydraulic simulation using EPANET 2.2 which identified the need to parallelize existing pipes and establish a new pipe with a diameter of 200 mm and a length of 1960 m that connects Ngarum Village and Jugo Village. In addition, expanded reservoir capacity is required to meet water demand because it will increase during the development year. Furthermore, based on the results of the demand pattern measurement, the pump schedule must be modified, as well as the quantity of functioning pumps to be able to meet the water supply demand when the development occurs.
