Customer satisfaction is one of the basic measures of the quality of drinking water service. Hence, this study was analyzed the perception of residential customers’ satisfaction of National water supply and drainage board (NWSDB) with domestic drinking water service in Karachchi divisional secretariat division of Kilinochchi district. The analyse was based on customers’ perception of ten selected satisfaction drivers, a set of structured questionnaire was administered for 150 residential customers of NWSDB using google form, however only 131 of them responded . The data was analyzed using descriptive analysis and a customer satisfaction index (CSI) model. The calculated CSI was 3.68 points on a 5 point scale, which meant that drinking water service in the study area was perceived as satisfactory by the residential customers. In addition, two-third of the customers were willing to pay for water, while one-third of them were not willing to pay based on their overall perception of the services of the NWSDB. This illustrates that the service of the NWSDB to its customers was adequate despite an improvement . To recommend, there is a positive correlation between safely managed/improved drinking water services and customers’ willingness to pay for water service. The NWSDB should undertake to improve drinking water services. Resultant, NWSDB should recover cost, provide water service to the whole district/national population to achieve the SDGS which are directly and indirectly depend on SDG6.
