Water Waste Enforcement
Valley Water enforces reports of water waste throughout Santa Clara County by contacting the responsible party, typically the property owner, to ensure they are aware of the issues that may be contributing to water waste. The goal of enforcement is to reduce water waste through raising awareness and connecting properties with our water conservation programs which can help achieve voluntary compliance.
Valley Water collaborates with our water retailers on how to best resolve reports of water waste. Depending upon the location of the reported water waste, either Valley Water or the water retailer will take action to achieve compliance.
During periods when Valley Water's Board has not called for mandatory water use reduction, Valley Water will use an educational-based enforcement approach to discourage water waste. There is currently no call for mandatory water use reduction; therefore, Valley Water will not be issuing fines for water waste violations. Water retailers and/or local municipalities may issue fines or take other enforcement actions, such as installing a flow restrictor, for water waste violations in their respective service areas.
During periods when Valley Water's Board has called for mandatory water use reduction, such as during a drought or other water shortage condition, Valley Water will bolster the educational-based approach by issuing fines to property owners who fail to address water water violations after receiving multiple notices from Valley Water.

What Happens When You Submit a Water Waste Report?
When Valley Water receives a water waste report, we open a case and make efforts to contact the responsible party for the property wasting water. Letters are mailed to the property owner and site visits are conducted in order to educate the property owner and prompt them to take action.
Please support our efforts in increasing water-use efficiency by reporting water waste issues.
First Report:
-
Notification letters are mailed in response to reports of broken sprinklers, excessive irrigation runoff, watering during restricted times/days, or other water waste issues. Notification letters inform the property owner of the reported violation and recommends ways to resolve it. In most cases, learning they have a broken sprinkler or are inadvertently wasting water by watering during restricted times, the resident or business owner understands and takes care of the issue.
Second Report:
- If Valley Water receives a subsequent water waste report for the same violation at the same location, a second notification letter will be sent to the property owner and the site may be inspected in an attempt to verify the violation.
Third Report:
- On the third report of the same water waste violation, Valley Water will refer the case to the water retailer responsible for that address.
- How the water retailer responds varies with the jurisdiction. Water retailers may contact the property to provide education, install a flow restrictor, or issue a fine.
- Check with your local water provider to learn more about their water waste procedures.
Did You Receive a Water Waste Letter?
When Valley Water receives an actionable water waste report, a notification letter is sent to the property owner. The intent of this letter is to inform the property owner of the reported water waste so they may take action to resolve the violation(s). Valley Water's ultimate goal is to conserve water by ensuring water waste issues are resolved by the responsible party in a timely manner.
If you received a water waste letter from us and would like to provide documentation you have resolved the reported water waste violation(s), that the water waste violation(s) was reported in error, or to ask questions, please contact us at [email protected] or (408) 630-2000.
Types of Water Waste to Report
Common examples of water waste from irrigation systems we encourage residents to report:
Overspray & Runoff
Watering sidewalks, roads, or other permeable hardscape can be avoided with more efficient irrigation equipment.
Runoff is when a landscape is oversaturated with water which causes the water to follow the path of least resistance off the landscape, instead of being absorbed into the soil. Runoff can be avoided by reducing irrigation timing and implementing a "cycle-and-soak" method.
Broken Irrigation
Irrigation equipment can break and cause high-flow geysers or flooding of the immediate area.
Irrigating or Watering During Restricted Hours
Find Your Water Retailer can help you determine the restricted hours to irrigate in your area. It's most efficient to water landscapes during the evening or early morning.
Washing a Car without a Positive Shut-Off Nozzle
Washing your car at home should be done with a positive shut-off nozzle, a bucket, and so the water runs off into your landscaping [PDF]. Many commercial car washes recycle their water: find a local car wash to save water and protect our waterways. MyWatershedWatch.org periodically offers discount cards for participating car washes.
Watering During or Immediately After Rainfall
No irrigation is allowed within 48 hours of measurable rainfall (defined as 1/4-inch of rain or more).
Leaking Water Meters
Contacting your water retailer can help you fix leaking water meters.
Where to Report Other Types of Water Waste
The water waste inspectors are best equipped to help address water waste from irrigation systems and landscapes. The additional contact information listed will help you find the proper team or agency to report other types of water waste and pollution.
Broken Fire Hydrants
Contact your water retailer to report broken or leaking fire hydrants.
Mosquito Sources
Mosquitoes are capable of transmitting diseases such as West Nile virus, Dengue Fever, and Malaria. Mosquitoes can breed in stagnant water in plastic pools, buckets, old tires, gutters with persistent standing water, etc.
The County of Santa Clara Vector Control District can help identify, eliminate, or remove these sources through measures including but not limited to mosquitofish. Related information can be found here. Report any breeding sources for follow up or anonymously through this online service request or by calling at (408) 918-4770.

When do you report an illegal discharge or dumping incident?
- When you see a person dumping anything into the storm drain. This activity is illegal.

- When you see dumped wastes and materials in or near the storm drain.
