Commissioners hear Rock Ridge sewer update; contractors set to start roughly $250,000 of repairs next week
Summary
County staff reported ongoing sewer defects at Rock Ridge, said remaining work will cost roughly $250,000 and advised monitoring after repairs to confirm whether remaining leaks are on private lines or the public system.
Commissioners heard an update on sewer work affecting the Rock Ridge area and were told contractors are scheduled to start repairs next week that the presenter estimated at roughly $250,000.
Why it matters: Commissioners expressed concern that finishing the remaining work and signing off before a significant weather event could leave unresolved leaks. If defects persist after county work, staff said that would indicate private laterals or household connections are the source and would require additional investigation.
County staff and consultants said the Rock Ridge project has involved flow monitoring and CCTV inspection to locate defects. “The work that’s starting next week, I believe, is to the tune of $250,000 ish,” a county staff member said. Staff described spot repairs, manhole replacements and, in some places, excavation where lining was not possible.
The timeline: Staff said Rock Ridge repairs should be completed in roughly three weeks, and the county will watch the system through spring rains to see whether further private-property investigations are needed. Commissioners asked for manhole maps and were told maps are available and will be provided.
What remains unresolved: County staff said it is not yet determined whether a single pump or multiple system-wide points are the cause; if leaks continue after repairs, the county may need to perform surveys to locate private connections or sub-surface inflow.
Ending: Staff and the county engineer will return with follow-up information when the upcoming work is complete and after the next significant rainfall.
