ALCOSAN’s Clean Water Plan (CWP) is a comprehensive, $2 billion, long-term plan to significantly reduce the overflows of diluted, untreated wastewater into the region’s rivers. Source control is one of the methods selected by ALCOSAN in the CWP to meet its compliance obligations. Building on the source control-related efforts undertaken by ALCOSAN and our customer municipalities, ALCOSAN developed a methodology to help identify and implement impactful source control projects in the Authority’s service area. Controlling the Source (CtS) documents that methodology, and identifies opportunities where ALCOSAN and our customer municipalities can work together to make an impactful investment in source control projects.
An online interactive Controlling the Source (CtS) Web Map has been created to accompany the plan to identify and evaluate green stormwater infrastructure (GSI) and other source control opportunities in the ALCOSAN service area. The map can be accessed below. See Appendix B of CtS for directions on how to use the Web Map, along with an explanation of the different layers of information that the Web Map contains.
