The method used in this research were preliminary study, data collection, data analysis, discussion, conclusions, and suggestions. Data collection was divided into primary data consisting of the existing condition of SPAM IKK Perbaungan, while secondary data consists of pipeline network, service data, and population data. At the same time, the data analysis was in the form of population projections, water demand projections, and evaluation of SPAM based on technical and institutional aspects. The questionnaire results showed that over 60% of the population who are not PDAM customers are interested in becoming customers and agreed to pay connection fees. SPAM IKK Perbaungan would serve four villages, namely Simpang Tiga Pekan, Batang Terap, Citaman Jernih, and Kota Galuh, with populations of 9,118, 3,352, 7,184, and 4,896, respectively. The implementation was divided into two stages, namely Phase I in 2022-2027, which served Simpang Tiga Pekan, Batang Terap, and Citaman Jernih with total water demand of 33.51 L/s, then Phase II in 2028- 2032, which added to serve Kota Galuh with a total water demand of 42.41 L/s. Keywords: Evaluation, Development, Drinking Water Supply System INTRODUCTION The provision of drinking water is one of the primary demands and socio- economic rights of the community that the Government must fulfil, both the regional Government and the central Government (Alamsyah, 2007; Amirullah et al., 2017). Availability of drinking water is one of the determinants of life in improving the welfare of the community, which is expected with the availability of drinking water can enhance the degree of public health so that there can be an increase in the economic growth of the community (Babbitt et al., 1962). Therefore, the provision of drinking water facilities and infrastructure is one of the keys to regional economic development (Enri et al., 1989). The implementation of SPAM is a series of activities in developing and managing facilities and infrastructure that follow the basic process for providing community drinking water (Kimpraswil, 2003). Following Government Regulation No. 122 of 2015 concerning the Development of a Drinking Water Supply System (SPAM), drinking water is the responsibility of Serdang Bedagai Regency, North Sumatra Province. Seeing the condition of the drinking water supply system in Serdang Bedagai Regency in the past, where programs for the development of facilities and infrastructure for drinking water supply often overlapped, provides a study to solve these problems systematically (Purnama & Suhartono, 2018). On the other hand, the management of drinking water facilities and infrastructure that have been built is also still overlapping, and some are managed by the community, PDAM Tirta Deli, Deli Serdang Regency, and the Technical Implementation Unit (UPT) for Drinking Water Services under the District Housing
