In recognition of the fact that a large portion of excessive wet weather flow in sanitary sewer systems comes from the privately-owned sector of the sanitary sewer system, the South Lyons Township Sanitary District has developed a Private Sector Program (PSP). This PSP is intended to prohibit new illegal clear water connections to the sanitary sewer system, compel property owners with illegal clear water connections or sources of excessive infiltration to eliminate them, establish a public information program to enhance awareness of the risks posed by illegal clear water connections, and establish a long-term program under which illegal connections that are costly to correct may be removed over time.
