Decentralized wastewater systems are not connected to the City’s central wastewater collection system conveying wastewater to the two wastewater treatment plants. This may include many system sizes, including individual onsite systems, clusters of homes each with septic tanks and a common final treatment and disposal system, or larger developments served by either conventional or alternative treatment and disposal systems.

Other information on OSSF management programs across the U.S. can be found at the National Small Flows Clearinghouse. Additional sources of information include:
