Pewaukee utility reports passing CMAR score and ongoing efforts to locate water losses
Summary
Staff reported the utility received a passing CMAR grade and summarized performance metrics including 43 inches of precipitation last year and efforts to find a significant leak that likely contributed to increased system water loss percentages.
City staff told the committee that the sewer utility’s annual CMAR report passed and was submitted to the Wisconsin DNR after approval by the common council in mid‑June. The presentation was informational and required no committee action.
Speaker 7 explained the CMAR process and said the utility is in compliance with DNR requirements. On performance indicators, Speaker 5 reported total precipitation of about 43 inches last year and the group discussed a higher‑than‑usual water‑loss percentage in the most recent PSC report. Speaker 6 said crews found a large leak during water main work on Westwood Drive that likely explained part of a reported 15% (or roughly 30% depending on reporting conventions) loss figure and that staff continue to search and repair failing saddles and laterals.
Staff emphasized there was nothing to move on at the meeting but invited committee members to submit comments on the metrics and the draft report as the utility finalizes the documentation for regulators.
