Stormwater Quality for 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 Businesses

  • Use non-toxic substitutes for chemicals whenever possible.
  • Control litter by sweeping and picking up trash regularly.
  • Sweep shop floors, materials processing and storage areas, access roads, parking lots and sidewalks. Do not wash down with a hose.
  • Properly contain and dispose of wash water, sweepings, and sediments.
Material Storage
  • Prevent spills from entering storm drains and discharge points.
  • Keep outdoor storage containers in good condition.
  • Use secondary containment measures for material and waste storage areas.
  • Clean up spills immediately to minimize safety hazards and prevent spills from reaching a storm drain inlet.
  • Use absorbent materials to clean small spills rather than hosing down the area. Remove the absorbent materials promptly and dispose of properly.
  • Whenever possible, sue chemical alternatives, or low-toxic chemicals.
  • Use landscaping pesticides and fertilizers only as needed.
  • Avoid over-watering to prevent excess runoff.
