Abstract

Abstract –In the distribution of clean water in the city of Surabaya, it is divided into 5 zones including
zone 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 clean
water 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 will
realize a pressure equalization program for water distribution to all customers.In this study, an analysis
was carried out to determine the amount of discharge needed in the Kalimas Baru area based on the
number of customers in the area which is projected until 2028. The results of the research obtained
were in the form of the method chosen to project the water demand for the Kalimas Baru area, namely
the arithmetic method with the result that the amount of water demand after being projected until 2028
is 0.01495 m3/s, with details of the water demand in residential homes of 0.013153 m3/s, in hospitals
of 0.00 1509 m3/s and in elementary schools it is 0.000227 m3/s.
