Abstract

The demand for clean water continues to increase along with population growth and the development of community activities. Hamparan Perak District is one of the service areas of PDAM Tirta Deli that experiences annual population growth, which has the potential to increase clean water demand in the future. This study aims to analyze population projections, calculate community clean water demand until 2044, and evaluate the suitability of PDAM Tirta Deli’s production capacity and raw water availability in meeting clean water demand within the SPAM IKK Hamparan Perak service area. The research method used is descriptive quantitative analysis utilizing both primary and secondary data. Population projections were calculated using arithmetic, geometric, and least square methods, after which the best method was selected based on correlation coefficient and standard deviation values. The clean water demand analysis was carried out based on domestic and non-domestic water demand, water losses, maximum daily factors, and peak hour factors in accordance with the standards of the Directorate General of Human Settlements. The analysis results indicate that the population within the SPAM IKK Hamparan Perak service area will continue to increase until 2044. This growth directly affects the annual increase in clean water demand. Total clean water demand is projected to rise from 106.695 L/s in 2024 to 114.303 L/s in 2044. Meanwhile, the current production capacity of PDAM Tirta Deli Hamparan Perak is 70 L/s with a raw water capacity of 90 L/s, which is insufficient to meet clean water demand under both existing and projected conditions. Therefore, efforts to develop production capacity and optimize the clean water supply system are required to sustainably fulfill community water needs.
