New sewer camera finds broken joints, grease issues; city activates automated water fill station
Summary
Public works staff demonstrated a newly purchased CCTV sewer camera that revealed infiltration through a broken joint and grease accumulation in a commercial service line; staff also explained the new automated self-pay fill station and its rationale
City public-works staff demonstrated a newly acquired sewer-inspection camera and showed footage of two problems: groundwater infiltration through a broken sewer joint and heavy grease accumulation inside a business service line. Staff said the camera will reduce the need to hire outside contractors for some inspections and will help target repairs.
Why it matters: Staff estimated that a single infiltration point producing roughly 20 gallons per minute could generate large monthly sewage volumes if left unaddressed; identifying and fixing broken pipe joints reduces infiltration, pump loads and treatment costs. The camera footage also identified grease from a business’ service line; staff reported they will require the business to clean the line and will coordinate hydro-jetting and grease removal.
What staff reported: - Camera capability: The new crawler system can pan, tilt and travel long runs while recording video and images; staff used it to locate a broken joint and a hydro-jet hose lodged in a mainline from previous work. - Grease issue: Footage showed the interior of a business’ 4-inch service line nearly blocked by grease; the business agreed to have a contractor hydro-jet and remove grease Friday. - Infiltration: Staff found a broken joint near Octagon (a local landmark in the footage) letting groundwater into the sewer; staff plan further TVing and repairs as part of a broader sewer assessment.
Water fill-station change: Separately, staff explained the new year-round automated self-pay water fill station at the RV dump (replacing ad hoc access to a county fill point). The station charges $5 per 1,000 gallons; staff said the measure protects the municipal potable system (backflow control and usage tracking), is not intended as a revenue stream, and ensures accountability for outside users that previously drew city water without oversight.
Next steps: Staff will coordinate repair or excavation where TV finds show structural damage, require the business to clean grease out of the service, and continue system-wide TVing to locate other infiltration sources. The water-fill changes are already in operation; staff will continue user education on the new self-pay system.
