Abstract –In the distribution of clean water in the city of Surabaya, it is divided into 5 zones includingzone 1 (southern region), zone 2 (eastern region), zone 3 (northern region), zone 4 (part of the northwest region) and zone 5 (west region). As the population increases each year, the distribution of cleanwater is also expanding which causes uneven distribution of water, especially in areas far from the DC(Distribution Center).Based on these problems, in 2023 PDAM Surya Sembada City of Surabaya willrealize a pressure equalization program for water distribution to all customers.In this study, an analysiswas carried out to determine the amount of discharge needed in the Kalimas Baru area based on thenumber of customers in the area which is projected until 2028. The results of the research obtainedwere in the form of the method chosen to project the water demand for the Kalimas Baru area, namelythe arithmetic method with the result that the amount of water demand after being projected until 2028is 0.01495 m3/s, with details of the water demand in residential homes of 0.013153 m3/s, in hospitalsof 0.00 1509 m3/s and in elementary schools it is 0.000227 m3/s
