State Water Conservation Regulation

In response to the ongoing severe drought, the State Water Resources Control Board approved an emergency regulation to ensure water agencies, their customers and state residents increase water conservation in urban settings or face possible fines or other enforcement.

The new conservation regulation is intended to reduce outdoor urban water use. The regulation, adopted by the State Water Board, mandates minimum actions to conserve water supplies both for this year and into 2015. 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 in 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 regulation makes an exception for health and safety circumstances.

Governor Brown has called on all Californians to reduce their water use by 20 percent and prevent water waste - visit to find out how everyone can do their part, and visit Drought.CA.Gov to learn more about how California is dealing with the effects of the drought.

It's Up To Us to Prevent Stormwater 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 stormwater 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 stormwater pollution prevention:

  • Contain all home improvement materials onsite and cleanup material spills without usage 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 stormwater 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.

Stormwater Quality and Regulations

Water quality is a growing concern in communities throughout the country and municipalities including San Dimas are focusing on stormwater runoff as one approach to address this concern. Stormwater runoff results from rain or melting snow in some areas that is 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 stormwater quality is not properly addressed. Federal regulations such as the National Pollutant Discharge Elimination System (NPDES) Permit are catalyst for San Dimas to create stormwater quality programs. .
