  • Cleaners – Store cleaning products where they are protected from rain, and prevent spills from reaching the storm drain system.
  • Chemicals – Any materials used or waste generated must be managed according to state regulations. Use secondary containment to prevent accidental discharge or leaks.
  • Equipment – Store materials like batteries and machinery in trays or with drip pans to contain potential leaks and spills.
  • Trash – Keep dumpster lids closed and place covers on all waste containers. Never put liquid waste into a dumpster. Store outdoor waste receptacles under cover to reduce exposure to rain that could wash pollutants into the storm drain system.

The beauty of all that surrounds us in Ventura County: from the hills, orchards, fields, creeks and to our neighborhoods and where we work, every bit of it is in our Watersheds. We invite you to join the cities' and county's efforts to protect Ventura County’s Watersheds by being more aware of what is added to the land and the harm it can do as it is taken, through storm drains to the Ventura and Santa Clara Rivers, Malibu and Calleguas Creeks, the bays and estuaries – and eventually into the Pacific Ocean.
