1. As a land developer, how can I obtain new water mainlines and service lines?

The District's Board of Directors must approve all new water mainlines and service lines. For more information, including the procedures and information required for the approval process, call the Maintenance Department at 909-624-0035, ext. 112.

2. How are low pressure problems addressed?

If a customer is experiencing a noticeable drop in water pressure, a call to the Maintenance Department usually results in the performance of a flow test that measures the amount of water the customer receives both at the water meter and at the front water spigot at the house or business. A pressure test is also taken.

Depending on the test results obtained from measuring the flow, the service line from the main waterline in the street to the meter may be upgraded. The District may also make recommendations that the water service line from the meter to the house be upgraded, which is the responsibility of the property owner. The District's responsibility ends at the water meter.

Because the District's entire distribution system operates on gravity, flows may not be significantly altered even after replacement of lines. Call the Maintenance Department at 909-624-0035, ext. 112 for more information.

3. How are water quality complaints addressed?

The most common water quality complaints received by the District involve odor, taste or color. Other complaints include sand or other debris, milky or cloudy water or air. The District's water quality operators investigate all complaints. If deemed appropriate, operators flush hydrants in the vicinity if taste or odor is persistent. In older buildings, internal plumbing lines may be the cause of many water quality issues.

Sand in the water is caused by wells that generate sand as the motor is turned on. Operators flush hydrants in the area thoroughly to alleviate this condition. Air in the system is also due to well operation. Flushing is also performed with necessary operational changes or repairs made. Reports of debris in the water are usually caused by faulty filter systems within the internal plumbing system of the residence or business.

Milky or cloudy water is typically dissolved oxygen combining as it passes through flow restrictions, such as faucet screens, resulting in a "milky" appearance. Fill a clear glass at your faucet and watch the water clear from the bottom of the glass to the top, as the air bubbles rise. For more information, call the Water Quality Department at 909-624-0035, ext. 122. You can also report a water quality concern to use by using our online form.

4. What should I do if I notice a water leak?

During regular business hours, contact customer service immediately. After regular business hours and on the weekend, call the District's main number, 909-624-0035 and follow the directions on the telephone menu to report an emergency water problem.

A District staff member will be notified and will come to the location to determine if the leak is the responsibility of the District or the homeowner. If the leak is determined to be an emergency and is the responsibility of the District, our staff will tend to the problem as soon as it is possible. If it is determined that the leak is not an emergency, the District must file a "Dig Alert" to request other utilities mark the location of their infrastructure (gas, electric, telephone, cable) prior to crews digging in the street. The District is required to allow at least 3 full business days for utilities to respond to Dig Alert requests.

For information, call the Maintenance Department at 909-624-0035, ext. 112. You can also report a leak online.
