A cross connection is any actual or potential link between our potable (drinking) water system and a non-potable source. These connections, if not properly protected, can allow contaminants like chemicals, fertilizers, or even sewage to backflow or back siphon into our clean water supply.
This survey helps us identify potential cross connections on your property so we can work together to ensure appropriate backflow prevention measures are in place. By understanding the connections on your property, we can collectively prevent contamination and maintain the high quality of our drinking water for everyone.
Per Schedule No. 8: Cross Connection Control of our WA UTC approved tariff, “all customers shall be surveyed as to the existence of cross connections pursuant to the definition of cross connections established by the Washington State Department of Health.”
For new customers, a survey will be required as part of the application prior to accepting the applicant as a customer.
A completed Cross Connection Survey is required for our records from all properties, even if no cross connection exists at your location.
