Home Maintenance

How you clean and maintain your home impacts the health of our local waterways.

Unlike drains inside our home that flow to sanitary sewers, the storm drains near our homes lead directly to creeks, wetlands and the Bay, without any treatment. That’s why it’s important to keep waste and wastewater from cleaning, maintenance and other chores around the house out of storm drains. Detergents and other household chemicals, debris and bacteria from pet feces are harmful to plants, fish and other aquatic organisms, and can even put the safety of our drinking water at risk.

Preventing pollution and choosing least toxic household products go a long way in keeping our waterways clean and healthy. The Clean Water Program works with retailers to promote such products. The Program also trains home maintenance service providers to adhere to best practices that protect our waterways. Please do your part too! Some simple routines can make a big difference.

When you sweep your driveway instead of hosing it down, you help keep Fred, Izzy, and our waterways healthy.

What You Can Do

Sweep, don’t hose, your driveway!

carpetcleanerBe sure to ask any cleaning company you hire where they dispose of wastewater. It should never be poured down a storm drain.Sweep up debris and dispose of it in the garbage. This will keep gutters unclogged and prevent the residue from automotive fluids and other pollutants get washed into storm drains. 

Dispose of wash water in sanitary sewers.

Never pour wash water into storm drains. Always use a sink or floor drain connected to the sewer. If this is not possible—for example, when rinsing out a garbage can—pour wash water onto a lawn where it can trickle into the ground.

Pet feces contain high concentrations of pathogens such as bacteria, parasites, and viruses. When rain and sprinkler water washes pet feces into storm drains, these pathogens end up in lakes and creeks posing a health risk to humans and wildlife.
