Backflow

On September 9, 1987 the Board of Directors of South Mesa Water Company adopted rules and regulations for backflow and cross-connection prevention. Those rules and regulations were updated and revised by order of the Board on April 12, 2000. South Mesa Water Company’s Backflow and Cross-Connection Prevention Policy aggressively enforces Title 17, Sections 7583 through 7605 of the California Code of Regulations. We appreciate our customer’s interest in our Backflow and Cross-Connection Program and any chance we get to educate our customers on water quality and the dangers of contamination is very important to us.

While South Mesa Water Company works diligently to deliver safe and reliable drinking water to its customers, some hazardous conditions may exist on customer properties which risk the safety of your drinking water supply. That’s why backflow and cross-connection prevention is an important part of our water quality program. Water distribution systems are designed to have higher pressure than a customer’s system to keep water flowing in the right direction. However, when there is a drop in pressure in our distribution system, a reverse flow – or backflow – can occur. This can be caused by incidents such as a severed fire hydrant, high demands such as firefighting, water main breaks and earthquakes. A backflow condition can result in water contamination, if hazardous cross-connections exist, endangering the quality of your drinking water.

What are cross-connections? Whenever a plumbing fixture is connected to the drinking water supply, a potential cross-connection exists. Some examples include:

  • Hose bibs
  • Livestock watering systems
  • Hose attachments to apply hazardous or harmful substances
  • Lawn irrigation systems
  • Ornamental fountains and ponds
  • Fire sprinkler systems
  • Solar heat systems
  • Wash basins and service sinks

What is backflow? If the water on your property is in contact with a hazardous, harmful, contaminated or non-potable substance and that water backflows into the main water system, it could cause illness or, in extreme cases, death.

What are hazards? South Mesa Water Company requires all commercial and industrial properties as well as residential properties with livestock to install and maintain a backflow prevention device. While single-family residences without livestock are not generally required to have a backflow device, you can help prevent backflow contamination by:

  • not leaving hoses attached or submerged in unsafe water
  • confirming that anti-siphon type valves are installed on irrigation valves.
  • installing hose bib vacuum breakers

South Mesa Water Company has over 390 backflow prevention assemblies installed within its service territory. All installed devices must be tested on an annual basis. Each year, customers will receive a reminder notice along with a list of Certified backflow testers. Failure to have the device tested could result in the termination of service.

Annually, a $20.00 administration fee will be applied to each backflow customer water account. Due to South Mesa Water Company’s status as a shareholder-owned corporation, company policy dictates that the Backflow and Cross-Connection Program be self-sustaining.

Customers who fail to comply with backflow requirements by the designated due date will receive a second notice and a $50 penalty will be added to their water account. Additionally, if a customer remains out of compliance for backflow testing within the time frame given on the second notice, South Mesa will have a certified back flow tester certify your backflow device(s). A fee of $75 will be added to the water account for each device that is tested, plus any additional cost for repairs. You will receive no further notice.

We, at South Mesa Water Company, hope this information provides a clear understanding of the need for Backflow and Cross-Connection Prevention. Protecting our water supply is everybody’s responsibility and South Mesa Water Company appreciates all those who have complied with the California Department of Health’s mandated requirements.
