# Pewaukee Water — water loss as filed PSC · PWS 4625 · filings 2016–2025 https://municorn.us/water-loss/wi/city-of-pewaukee-water-utility/ > **Cite as:** Municorn.us, "Pewaukee Water — water loss as filed", Municorn water loss index, https://municorn.us/water-loss/wi/city-of-pewaukee-water-utility/ (source filings retrieved 2026-09-08). > **Licence:** CC BY 4.0 — https://creativecommons.org/licenses/by/4.0/ — reuse and redistribution are permitted with attribution to Municorn.us and a link to this URL. > **Caveat that must travel with these figures:** "Water loss" is at least three different quantities depending on the jurisdiction, and nothing here supports a comparison between states. ## Summary Pewaukee Water reported **21.6% non-revenue water** in FY2025, higher than 66% of the 562 Wisconsin systems that filed that year. The figure is trending worse across the record. **The water balance is not a check here.** PSC derives water losses from system input minus authorized consumption, so this decomposition holds by construction. ## Filed history | Year | Non-revenue water % | System input (MG) | |---|---|---| | 2025 | 21.6% | 516.5 | | 2024 | 19.1% | 511.4 | | 2023 | 13.3% | 512 | | 2022 | 11.8% | 461.5 | | 2021 | 9.7% | 474.7 | | 2020 | 11.3% | 495.6 | | 2019 | 10.4% | 448.3 | | 2018 | 13.3% | 465.6 | | 2017 | 12.0% | 466.4 | | 2016 | 9.8% | 464.9 | ## What this source cannot say No filed year on this page carries a retail rate or a production cost, so no figure here is valued. A loss volume is not a loss in dollars, and this site will not supply a price that was not filed. ## Source Public Service Commission of Wisconsin, municipal annual report Schedule W-15.

This is principal outstanding on the water utility's own balance sheet, on the Commission's own test: it files no electric operating report. | Year | Debt outstanding | Issues | Net revenue | Interest | Coverage | |---|---:|---:|---:|---:|---:| | 2025 | $8.5M | 4 | $710,106 | $0 | — | | 2024 | $9.1M | 5 | $1.2M | $107,317 | 10.76 | | 2023 | $9.8M | 5 | -$451,971 | $347,885 | -1.30 | | 2022 | $10.4M | 5 | $588,782 | $224,420 | 2.62 | | 2021 | $6.2M | 4 | $853,529 | $163,082 | 5.23 | | 2020 | $6.6M | 4 | $425,042 | $172,551 | 2.46 | | 2019 | $7.1M | 4 | $244,993 | $181,753 | 1.35 | | 2018 | $7.6M | 4 | $365,581 | $148,312 | 2.46 | | 2017 | $6.5M | 3 | $477,947 | $147,354 | 3.24 | | 2016 | $7.0M | 3 | $362,845 | $112,501 | 3.23 | This utility filed no interest expense for the year, so there is nothing for a coverage ratio to cover. Figures are as filed with the Commission under Wis. Admin. Code ch. PSC 185 and are not audited as presented. Nothing here is a credit opinion, an implied rating, or a judgement that any figure is sufficient. Source: Public Service Commission of Wisconsin, annual report financial schedules, 2016–2025.
