Storm Water Management

The City of La Puente believes protecting our waterways is part of maintaining a beautiful city. La Puente is located in the Upper San Gabriel River watershed. Rainfall and runoff flow from watersheds to local storm drains, creeks, and the Pacific Ocean without being treated. It is important to keep our watersheds clean to ensure beautiful, health, and safe rivers and beaches

What is storm water?

Storm water is runoff from rainfall that drains through natural and urban areas. Storm water flows into storm drains, through creeks, and eventually into the ocean and can pick up urban pollutants along the way. The City has a National Pollutant Discharge Elimination System (NPDES) permit in which the City must take many measures to prevent storm water pollution. The permit contains multiple programs that are implemented by the City: public outreach, illicit discharge and illicit connection elimination, development planning, development construction, commercial and industrial facilities inspections, and public agency activities. With the implementation of these programs, the City can achieve water-quality standards as enforced by the Regional Water Quality Control Board – Los Angeles.

You can help!

Be aware of these household pollutants and how you can prevent storm water pollution:

  • Do not dump anything into the streets, gutter, or storm drain inlets.
  • Household fertilizers, pesticides, and other hazardous wastes are toxic. Always follow the directions on the container, avoid application before rain, and avoid runoff.
  • Avoid washing off driveways, sidewalks, and walkways.
  • Pet waste contains harmful bacteria. Always pick up after your pet and dispose of waste in a nearby trash can.
  • Prevent unnecessary irrigation runoff by fixing sprinkler heads or installing drip irrigation.
  • Do not litter and always place trash, including cigarette butts, in a proper waste receptacle.
  • Wash your car at a car wash or where wash water will drain to a grassy or landscaped area. Car washes collect wash water and prevent soaps from entering the storm drain system.
  • Call 1-888-CLEANLA or visit for information on upcoming household hazardous waste collection events near you.
  • Take Action! Volunteer at a local creek cleanup. Considering joining a California Coastal Cleanup Day or a Friends of the LA River event.

Report Illegal Dumping or Discharges, please call the countywide hotline at 1-888-CLEANLA or alert the City through the GO REQUEST online complaint system.
