<![CDATA[Access to clean water is a fundamental community need that requires careful planning based on population growth and the capacity of existing water supply infrastructure. Telawang District, East Kotawaringin Regency, continues to face limitations in clean water services, as the existing non-PDAM water supply system serving the Ibu Kota Kecamatan (IKK, district administrative center) has a production capacity of only 10 L/s and serves 394 household connections, equivalent to approximately 1,576 people or 9.6% of the total population of 16,397. This study aimed to project population growth and estimate clean water demand to support the development of the Drinking Water Supply System (Sistem Penyediaan Air Minum, SPAM) within the Sebabi IKK service area, particularly Sebabi Village and Sumber Makmur Village. Data were collected through official documents and field surveys, while population projections were calculated using the geometric growth method in accordance with relevant water supply planning guidelines. The results indicated that the combined peak-hour water demand was projected to increase from 11.39 L/s in 2023 to 37.39 L/s in 2032 and 67.73 L/s in 2043. To meet the projected demand through 2032, the estimated raw water flow requirement was 35 L/s, which was increased to a design capacity of 40 L/s to account for pumping efficiency, while the proposed water treatment plant capacity was 35 L/s. The study concluded that projected population growth would substantially increase clean water demand, highlighting the need to expand SPAM infrastructure and align production and distribution capacities with future service requirements.]]>
