People growth and area development need clean water as primary needs acquirement of its society. Because of its important role, there needed clean water reserve, whether in quantity or quality. City development and all life asect in indirect way influenced the huge needs of clean water. The existing distribution network in gravity way with heterogen pipe variation. Exaggerate pipe construction and many turn in pipes caused many reduction to pressure. Control to pressure tried to plan clean water needs service of the consumer. In distribution network system development, network plan was simplified to minimize exaggerate network and minimize reducing caused by pipes turn. This development hoped to increase wealth and life quality of Gondanglegi sub-district people about clean water, along with people growth and society level which increased. From analysis there found citizen in 2019 counted with Geometric method for 20026 soul, for water needs in 2019 found average water needs 10.5 lt/sec, maximum daily needs 12.0 lt/sec, and peak hour needs 15.7 lt/sec. Pipe network of Gondanglegi sub-district needs pipe exchange from existing condition into development 2019 with 15 amounts. Simulation with water Net software found pipe network dimension for 2019. Development distribution network pipe dimension from the source to customer were: 110 mm, 90 mm, 75 mm, 63 mm, 50 mm, 40 mm, and 30 mm.
