Dog and Livestock Owner
When it rains, dog and other animal waste left on lawns, sidewalks and in the street can wash into stormdrains and flow untreated directly into our local waterways. The bacteria and risk of disease threatens the health of our community. Follow these easy steps to be a responsible pet owner and help protect your family and environment’s health.
Disposal of Pet Waste
Home Improvement
Many items we use everyday-such as paints, pesticides, fertilizers, motor oil, etc-often make their way into the stormdrain system and are not treated before entering waterways. More information on how to properly dispose of common household waste materials can be found in the Household Hazardous Waste section of this website and in the following brochure.
Household Hazardous Waste
Lawncare and Gardening
Improper lawncare and gardening can adversely affect our environment such as sprinkler runoff that carries pesticides and fertilizers into the stormdrain system. Grass clippings, leaves and other yard waste gets swept or blown into the street, clogging catch basins and polluting waterways.
