Illicit Discharge Detection & Elimination
Illicit discharges are the intentional dumping or accidentally spilling of materials into the storm sewer, gutters, drainageways, waterways, and ditches. It is anything (any unauthorized substance) entering into the storm sewer system excluding stormwater. Some examples that harm our water supply are:
- Homeowners and landscapers staging compost and topsoil piles in the street for future landscaping activities. This causes decreased flood control volume, creating algae blooms in ponds and waterways.
- A swimming pool owner sandblasts paint off the pool walls and releases the paint residue and pool water onto the street, flowing into a storm sewer inlet and entering a creek.
- Restaurant worker dumps used cooking oil into a parking lot drain that connects to a reservoir used for drinking water.
- Homeowner washes paint brushes off in the street where the colored paint travels to a storm sewer inlet and discharges to the neighborhood waterway along a bike path.
- A contractor pressure washes a dirty parking lot, washing trash, oil, grease, metals, salts and sand into the adjacent creek.
- A resident walks his dog in a neighborhood park and picks up after his dog but tosses the bags of pet waste into the storm sewer inlet.
- A concrete truck at a construction site dumps the remaining concrete liquid on a lot that drains to a creek. Concrete waste is similar to Drano and is harmful to animals and people that come in contact with the water.
