Maplewood Sanitary District No 1
What Maplewood Sanitary District No 1 filed with PSC about the water it produced and the water it billed for, 2016–2025 — and what the filing does and does not let anyone verify.
- Non-revenue water, FY2025
- 16.7% Computed from filed system input and billed consumption.
- system input volume 2.13 sheet Sheet1, cell H301 · thousands of gallons, declared in the column header, divided by 1,000 · net of water sold to wholesale customers, which is the volume entering this utility's own distribution system
- billed authorized consumption 1.77 sheet Sheet1, cell I301 · thousands of gallons, declared in the column header, divided by 1,000
- Recoverable annually
- — Not estimable from what PSC publishes. A loss percentage cannot be priced without the volume it is a share of.
- Balance check
- inapplicable PSC derives water losses from system input minus authorized consumption, so this decomposition holds by construction.

What the record shows
16.7% non-revenue water in FY2025, higher than 51% of the 562 Wisconsin systems that filed that year.
- The figure is getting worse across the record.
- 1 of 10 years carry no figure — which by PSC's own note means it had insufficient data to calculate one.
Debt outstanding, and what covers the interest
No bonds outstanding at the end of 2025. This is principal outstanding on a combined water and sewer utility's balance sheet, which the Commission files as one.
No bond balance is not the same as no debt. 2,310 of the 5,921 utility-years in this extract file no bonds, and many of those utilities pay interest anyway on an advance from their own municipality, which the Commission files under account 430 rather than as a bond.

This utility's balance sheet and income statement are water and sewer, filed as one. A coverage ratio computed from them would put one service's revenue over another service's interest.
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.

PSC derives water losses from system input minus authorized consumption, so these parts sum to the whole on every filing. What a filing can get wrong is which of these numbers were measured.
Where these volumes come from
- System input 2.13 MG sheet Sheet1, cell H301 · thousands of gallons, declared in the column header, divided by 1,000 · net of water sold to wholesale customers, which is the volume entering this utility's own distribution system
- Billed authorized 1.77 MG sheet Sheet1, cell I301 · thousands of gallons, declared in the column header, divided by 1,000
- Unbilled authorized 0.03 MG sheet Sheet1, cell O301 · thousands of gallons, declared in the column header, divided by 1,000
- Apparent loss 0 MG sheet Sheet1, cell R301 · thousands of gallons, declared in the column header, divided by 1,000
- Real loss 0.33 MG sheet Sheet1, cell U301 · thousands of gallons, declared in the column header, divided by 1,000
