Clean County Initiative

Washington County’s Clean County Initiative is an integration of the County’s compliance efforts for the Federal Clean Water Act. Regulations are set by the Environmental Protection Agency and administered by the Maryland Department of the Environment. Washington County has compliance requirements on multiple water quality standards; each has a specific purpose, but improvement efforts can have overlapping benefits. The County budgets for stormwater retrofits, stream restorations, and tree plantings.

If you see illegal trash dumping or illicit discharges please report them through our online forms:

Pet Waste Cleanup

Did you know that due to a high protein diet, pet waste is highly acidic and will burn grass? Through partnership with PetSmart, Washington County has placed 70 pet waste stations in seven county parks. Properly disposing of your pet’s waste reduces the amount of water polluting materials and bacteria in our streams and storm drains. Please remember to clean up after your pets while you are walking and enjoy the many outdoor activities Washington County has to offer.

Rain Barrel

A rain barrel is a system that collects and stores rainwater from your roof that would otherwise be lost to run off and diverted to storm drains and streams. Lawn and garden watering make up nearly 40% of total household water use during the summer. A rain barrel collects water and stores it for when you need it most – during periods of droughts to water plants, wash your car or add water to your swimming pool. Saving water not only helps protect the environment, but it could save you money!

Stream Restoration & Tree Planting

Washington County and organizations such as the Board of Education and the Antietam Watershed Alliance, participate in numerous stream cleanups and tree plantings around the county. Numerous items have been removed and disposed appropriately from many Washington County areas that help keep streams and the environment clean. For more information or to become a volunteer, please contact the Division of Environmental Management.

Septic Stewardship

The septic tank is an underground watertight container that is usually made with concrete, fiberglass or polyethylene. It holds wastewater long enough for solids to settle out to form sludge, oil and grease to float to the surface as scum. It allows partial decomposition of solid materials.
