State Water Conservation Regulations
Information regarding water usage, regulations, and possible rebates may be obtained from the City’s water provider, Golden State Water, www.gswater.com/san-dimas.

In response to the ongoing limited water resources in California, the State Water Resources Control Board approved emergency regulations to ensure water agencies, their customers, and state residents increase water conservation in urban settings or face possible fines or other enforcement.  The conservation regulations are intended to reduce outdoor urban water use. These regulations, adopted by the State Water Board, mandate minimum actions to conserve water supplies. Most Californians use more water outdoors than indoors. In some areas, 50 percent or more of daily water use is for lawns and outdoor landscaping.

Many communities and water suppliers have taken bold steps over the years and this year to reduce water use; however, many have not and much more can and should be done statewide to extend diminishing water supplies. With this regulation, all Californians will be expected to stop: washing down driveways and sidewalks; watering of outdoor landscapes that cause excess runoff; using a hose to wash a motor vehicle, unless the hose is fitted with a shut-off nozzle, and using potable water in a fountain or decorative water feature unless the water recirculates. The regulations make an exception for health and safety circumstances.

Storm Water Pollution Prevention

It’s Up To Us to Prevent Storm-Water Pollution
The City of San Dimas has two drainage systems, (1) the sewers and (2) the storm drains. The storm drain system was designed to prevent flooding by carrying excess rainwater away from city streets out to the San Gabriel River and finally, out to the ocean. During storms in urban areas, rainwater runoff carries pollutants generated from commercial businesses, residential areas, streets, and sidewalks, directly to the ocean, creating storm-water pollution. Materials such as sediment, paint, plaster, yard waste, used motor oil, animal waste, and trash contain chemicals, nutrients, and bacteria that are harmful to aquatic life and humans.

Please consider the best management practices (BMPs) listed below to assist with storm-water pollution prevention:

  • Contain all home improvement materials onsite and cleanup material spills without the use of water.
  • Properly dispose of residual materials at a local collection center, household hazardous waste collection event, or in coordination with Waste Management.
  • Properly dispose of all yard waste in your green or burgundy cart.
  • Properly dispose of trash and construction waste.
  • Do not dump or pour leftover materials in the gutter, street, or storm drains.
Illegal disposal of any material other than storm-water in the storm drain system is a violation of the National Pollutant Discharge Elimination System (NPDES) Permit (Section 402 of the Federal Clean Water Act). Violators and cities can be subject to serious financial penalties in excess of $10,000 per day.  If you observe this occurring, please call the City’s Environmental Coordinator at 909.394.6242 during City business hours.  After hours, to report illegal dumping/discharges, anywhere in Los Angeles County, into the storm drain system, call 1.888.CLEAN LA.

Storm-Water Quality and Regulations
Water quality is a growing concern in communities throughout the country and municipalities including San Dimas are focusing on storm-water runoff as one approach to address this concern. Storm-water runoff results from rain or melting snow in some areas that are not absorbed into the ground. Runoff is also generated outside of the “rainy season” by nuisance water resulting from activities such as over-watering lawns, vehicle washing, or draining of swimming pools and other water features. This excess water carries trash, motor oil, fertilizers, pet waste, and other contaminants directly to our lakes, streams, and beaches untreated. Excess contaminants dumped into our environment and the depletion of our valuable water resources negatively affect the entire community. Many cities like San Dimas will be at risk of serious fiscal impacts, including fines (could be up to $10,000 per day per violation), costly retrofit projects, and repairs if the storm-water quality is not properly addressed. Federal regulations such as the National Pollutant Discharge Elimination System (NPDES) Permit are a catalyst for San Dimas to create storm-water quality programs.

For additional information regarding the new and previous NPDES Permit requirements, as well as program updates, please call 909. 394.6242.
