The North Davis Sewer Association was formed in 1946 to acquire from the U.S. government the North Davis Sewer constructed in 1943 with federal funding. A Special Service District was organized out of the Association in 1954 giving it authority to levy taxes, issue bonds, and construct a sewage collection and treatment system. Today, the District collects and treats wastewater from approximately 80 square miles with a population of about 238,000. The District is made up of the cities of Clearfield, Clinton, Layton, Roy, Sunset, Syracuse, West Point, and a small area of Kaysville, Hill Air Force Base, and areas of unincorporated Davis and Weber counties. The District serves the area extending north to south from Roy to Kaysville, and east to west from the Wasatch Mountains to the Great Salt Lake.
