Access to clean water is a fundamental and sustainable necessity for the well-being of human beings, requiring consistent provision. Given the ongoing population growth in Karo Regency, especially in terms of the use of clean water, a significant increase in demand for clean water is anticipated in the coming years. This research aims to understand the demand and availability of clean water required by the community in Karo Regency until the year 2033. The study involves an analysis of the demand for clean water at the PDAM Tirta Malem unit in Karo Regency, using data such as population figures from the last decade, the number of customers over the past ten years, andinformation on the water needs of the population in Karo Regency. The research findings indicate that the projected increase in the number of customers in Karo Regency will result in a demand for 212,644.7 liters per second of clean water in the service area. However, it is anticipated that the existing sources of clean water will be sufficient to meet this demand by the year 2033. This statement is supported by the total demand for clean water based on projectionsfor various types of customers in the service area of Karo Regency in 2033, which is 212,644.7 liters per second, still within the total availability of water that can be produced by the existing springs, which is 373 liters per second.
