General Category Source Action
Municipal Sanitary Infrastructure Combined Sewer Overflows Replace infrastructure, if possible
Sanitary Sewer Bypasses/Overflows Line sanitary sewer pipes
Inflow and Infiltration Minimize and eliminate through repairing damaged sewers
Illicit discharges from unsewered communities Detect and eliminate illicit discharges
Human Sanitary Sources Leaky/failing septics Update and enforce SSTS ordinances
Educate homeowners on septic system maintenance and opportunities for replacement
Implement higher standards for setbacks for installing septics near waterbodies
Porta-potties Ensure construction site temporary toiles have appropriate pollution prevention BMPs
Domestic pets Dogs, cats, dog parks, walking trails, residential yard and sidewalk runoff (spring runoff after winter accumulation) Pet waste disposal stations along trails, in dog parks, etc.
Pass and enforce pet waste ordinances and educate pet owners about them
Add infiltration BMPs downstream of parks/residential areas and upstream of stormwater pipes (i.e., somewhere between the park/residential area and the stormwater outfall so as to intercept and infiltrate some or all of the flow from these areas)
Reduce transport from parks, residential, and other areas by the use of buffers and other disconnection of flow pathways (e.g. impervious surface, disconnection, downspout disconnection)
