How to Ensure Clean Water and Clean Beaches for All of San Diego
Many people think that when water flows into a storm drain it is treated, but the storm drain system and the sanitary sewer system are not connected. Everything that enters storm drains flows UNTREATED directly into our creeks, rivers, bays, beaches and, ultimately, the ocean. That stormwater often contains contaminants – including chemicals, trash and vehicle fluids – all of which pollute our beaches and harm fish and wildlife.
There are several actions that San Diegans and local businesses can take to prevent stormwater pollution. By keeping the tips and best practices below in mind, you can help reduce the pollution going into storm drains and ensure clean water and clean beaches for all of San Diego.
Stormwater pollution is the biggest threat to water quality in the San Diego region. Every San Diegan can do their part to reduce that pollution by implementing the following actions in their daily lives.
- Pesticides not only kill garden invaders, but they also poison fish and contaminate ocean water. Use organic or non-toxic fertilizers and pesticides and don’t fertilize near ditches, gutters or storm drains.
- Don’t dump household cleaners, paint products or motor oil on the ground – all paths lead to the ocean!
- Wash your car at a commercial wash instead of in your driveway or alley.
- Do not sweep leaves into the street or storm drain; instead, place yard clippings in appropriate waste containers.
- Dispose of car oil and grease properly.
- Clear your roof gutters of debris so water can flow smoothly.
- Consider incorporating native plants into your landscaping to absorb excess rainwater.
- Properly dispose of all pet waste.
Stormwater pollution is the biggest threat to water quality in the San Diego region. Every San Diego business can do its part to reduce that pollution by implementing the following actions as part of regular daily cleaning and maintenance routines.
- Keep dumpsters in good condition with lids closed so that no contaminants leak out.
- Take inventory of where your business stores, handles and disposes of chemicals, securing them to prevent accidental spills.
- Hazardous waste materials should have secondary containment barriers in order to stop runoff.
- Avoid hosing down dirty paved areas, such as around a dumpster. When necessary, seek non-toxic, eco-friendly cleaning alternatives.
- In larger areas, use a professional cleaning machine service, as they are required to dispose of wastewater at approved facilities.
- Have a plan to clean up spills quickly and safely.
- Post signs to remind employees of pollution prevention best practices.
- Remember: Preventing pollution cuts costs, avoids expensive cleanups and may protect your business from fines!

The Importance of Stormwater Management
Stormwater infrastructure is important but often underappreciated because much of the equipment and facilities are located underground. Learn more about how that infrastructure is managed with the goal of reducing neighborhood flooding and pollution.
