The Washington State Department of Public Health is now requiring that all District customers complete the Cross-Connection Control Survey Form. For more information please visit the Cross-Connection Control Survey section.
Cross-Connection Control Surveys are now Required by the Washington State Department of Health
The Washington State Department of Health now requires that all water purveyors protect the public water supply from contamination by eliminating actual cross-connections and reducing the hazard of potential cross-connections. It also requires all purveyors to report annually the potential for these hazards. Survey forms will be sent to all district customers and completion and return of the forms to the district is required by the Washington State Department of Health. Your completion of this survey will assist the District in satisfying these requirements.
A cross-connection is an unprotected or improper connection to the system that may cause contamination or pollution to enter the public system. It can be a direct or indirect connection with any other water source, sewer, drain, conduit, pool, storage tank, plumbing fixture or other device which contains, or may contain, contaminated water, sewage or other liquid or waste of unknown or unsafe quality. The system water pressure can suddenly drop because of heavy usage, a firefighting in the area or a broken main. Should any of these condition occur, contamination may be siphoned back into your plumbing system from unprotected cross-connections with your home. Even though the District has a very reliable water distribution system, pressure drops can still occur. All homes have potential cross-connections. The water pipes and plumbing fixtures may be the link for contamination to get back into the drinking water supply. They can be a serious health hazard. The reversing of the flow direction in the pipes is called backflow. Backflow from cross-connections can result in chemicals, poisons and bacteria entering the water you drink.
Examples of cross-connections include:
- Improperly installed irrigation systems which may allow back-siphoning.
- Improperly plumbed water-using devices such as hot-tubs, boilers or dishwashers.
- Irrigation systems served by an auxiliary source, such as a private well or creek, with inter-ties to the domestic piping system.
- Interconnections between potable and non-potable water systems.
Most modern plumbing systems have backflow devices built in (toilets, sinks, modern hose connections). For more information and detailed descriptions of cross-connections, please view the EPA Cross-connection info document.
Every customer served by Water District 119 is required to complete and return a Cross-connection Control Survey form. The survey includes identifying plumbing fixtures present in your home or business. After the District receives the completed surveys, we will review that data and determine homes and businesses that need plumbing inspections, and will notify them by phone or mail.
Help to protect your yourself, your neighbors and your community to eliminated unprotected cross-connections by completing and returning your survey form.
Forms can be returned with your regular water bill payment, or mailed to:
