Stormwater Management

The Town of New Canaan’s Public Works Department would like to remind residents that it’s everyone’s responsibility to protect our water courses. That’s because storm drains and roadside ditches lead directly to our ponds and rivers. So, any oil, pet waste, leaves, trash, or dirty water from washing your car that enters a storm drain gets into our water courses. 

With 20,000 people living in New Canaan, we all need to be aware of what goes into our storm drains.

Mercury Toxic, Persistent, Preventable
Mercury, a useful but toxic metal, is being phased out of many industrial and consumer uses. 
However, some mercury can be released to the environment from consumer items discarded 
as solid waste and from mercury dumped down household drains. 

Considering acceptable alternatives to mercury and responsible handling of mercury-containing wastes will help keep mercury out of the environment. 

The Town of New Canaan Public Works Department wants you to prevent mercury from contaminating our environment by: 

1. Reducing your use of mercury containing items 
2. Recycling what you can 
3. Disposing of ALL mercury waste properly--------you can keep mercury out of the water and the atmosphere.

What you can do to prevent Stormwater Pollution

Urban Stormwater Runoff , Click here for link 

Keep litter, pet wastes, leaves, and debris out of street gutters and storm drains--these outlets drain directly to lake, streams, rivers, and wetlands. 
Apply lawn and garden chemicals sparingly and according to directions. 
Dispose of used oil, antifreeze, paints, and other household chemicals properly, not in storm sewers or drains. If your community does not already have a program for collecting household hazardous wastes, ask your local government to establish one. 
Clean up spilled brake fluid, oil, grease, and antifreeze. Do not hose them into the street where they can eventually reach local streams and lakes. 
Control soil erosion on your property by planting ground cover and stabilizing erosion-prone areas.

Encourage local government officials to develop construction erosion/sediment control ordinances in your community. 
Have your septic system inspected and pumped, at a minimum, every 3-5 years so that it operates properly. 
Purchase household detergents and cleaners that are low in phosphorous to reduce the amount of nutrients discharged into our lakes, streams and coastal waters.

Agriculture 
Manage animal waste to minimize contamination of surface water and ground water. 
Protect drinking water by using less pesticides and fertilizers. 
Reduce soil erosion by using conservation practices and other applicable best management practices. 
Dispose of pesticides in an approved manner.

What the Public Works Department is Doing
Yearly the Town of New Canaan Public Works Department in conjunction with the Town’s Engineering Department sampled 6 (six) stormwater outfalls. These outfalls represented the business district and residential area outfalls. They also represented stormwater that discharged into the Five Mile River and the Silvermine River. 

The Public works Department also worked diligently in sweeping the Town’s roads and cleaning and marking the catch basins.
