Storm Drains Connect
The stormwater system is more than gutters and storm drains. These are a small part of the overall network of stormwater facilities. Gutters are designed to collect stormwater runoff and get it off the streets quickly. While gutters are designed for speed, other stormwater facilities work to slow the water's flow. This not only reduces the danger of flooding, but also allows time for pollutants to settle out of the water.
Lafayette's natural drainageways and natural-looking, engineered facilities greatly reduce the danger of flooding and the impact of stormwater pollutants on our waterways.
Stormwater Facilities
Common Urban Pollutants
According to the U.S. Environmental Protection Agency, urban stormwater is a major source of water quality damage, rivaling discharges from factories.
Common pollutants include:
-
Sediment from construction sites
-
Motor oil, grease, antifreeze and other automotive fluids
-
Foam cups, plastics, cigarette butts and paper
-
Trimmings from trees, landscaping and lawns
-
Cleaners and solvents
-
Pesticides, fertilizers and herbicides
-
Pet droppings, viruses and bacteria
Water from storms, snow melt and everyday activities such as lawn watering and car washing picks up debris, chemicals and other pollutants as it flows into the storm drains.
