Summary

Town staff briefed council on an annual cross-connection control program to inventory irrigation and fire-suppression backflow prevention devices and set a June 30 reporting deadline; staff reported counts and said testing had not yet begun.

Town staff told the Interlaken Town Council on April 1 that the town is beginning its annual cross-connection control program to protect the culinary water system from potential contamination via irrigation or fire-suppression systems.

Staff said the program is an annual state and county requirement and the town adopted an ordinance last May that outlines the requirement. The town set a June 30 deadline for property owners to report backflow prevention devices and required annual testing; staff said this timeline is intended to complete compliance before the busy irrigation season.

At the meeting staff presented preliminary survey counts: 43 properties reported irrigation systems; 106 lots were reported without irrigation; 38 irrigation systems have a backflow prevention device installed and five irrigation systems were reported without a device. For fire suppression, staff reported 16 homes with fire-suppression systems and 15 of those reported a backflow prevention device. Staff said none of the devices had been tested yet for the current year and that additional outreach is needed for about 24 lots that had not yet responded.

Staff said they would compile the inventory and submit required reports to the state. Council members suggested adding notice language and a deadline to the town website and using the existing online bill-pay and remote-deposit channels for outreach and record-keeping. No formal council vote was taken on the program; staff described next steps as outreach, data collection, and scheduling testing.
