Stormwater Quality for Landscaping Businesses

The storm drainage system is designed to collect stormwater - rain and snowmelt - and release it directly into Windsor waterways. Pollutants are transported in stormwater as rain and snowmelt travel across surfaces such as lawns, roads and parking lots, picking up substances such as fertilizers, pesticides, oil and sediments before entering rivers and streams. Contaminants that enter our waterways degrade the quality of drinking water sources for people downstream, our own recreation areas, and the quality of fish and wildlife habitats. 

Best Management Practices for Landscaping Businesses

Material Storage
  • Store all containers holding powder and liquid materials under cover to protect it from rain and snow.
  • Use secondary containment devices or construct dikes/curbs to contain any possible leaks.
  • Keep containers closed and secure.
  • Store soil and mulch piles in contained areas where they cannot be washed into the storm drainage system. When these materials are transported for use on site, store them on the lot and out of the street where they won’t be washed into the street and storm drain system with overspray from irrigation or stormwater.
Fertilizers, Herbicides, and Pesticides
  • Whenever possible, use chemical alternatives, or low-toxic chemicals.
  • Follow manufacturer’s recommendations for safe use and disposal.
  • Use the smallest amount necessary.
  • Apply at optimal times for the specific application.
Equipment maintenance
  • Inspect vehicles and equipment for leaks regularly. Fix problems as soon as possible.
  • When draining fluids, use a drip pan and/or a funnel to prevent any spills.
  • Keep a cleanup kit of safety equipment and absorbent materials, such as kitty litter or sand for spills.
  • Never hose down streets or sidewalks to clean. Use a broom and properly dispose of the sweepings.
Cleaners and solvents
  • Read labels carefully and follow directions.
  • Dispose of unused portions properly.
  • Follow good cleanup practices.
  • Whenever possible, purchase water based cleaning products. Look for products labeled non-toxic, non-petroleum based, ammonia-free, phosphate-free, and/or biodegradable.
