How rates are calculated
Sewer customers pay a quarterly bill split into two parts: an Operating (O&M) charge per Benefit Unit, and a Capital Charge per EDU to service the EFC bond. One BU is meant to represent about 150 gallons per day of water use. The Board sets the operating rate by dividing what it expects to spend on running the WWTP by the number of billing units, adjusted for an expected fraction of unpaid bills.
The arithmetic
Working from the adopted operating budget to a per-BU quarterly rate. Numbers below come from the FY 26/27adopted budget, FY 24-25 AFR (for the bad-debt buffer), and the Village Treasurer's billing-unit count.
Per-account allocation
The total operating cost is distributed across billing units. Each property pays the per-BU rate × its assigned number of BUs. The Board has used three different allocation models over time — compare them below.
Pre-2026 fixture-based BU values (mostly 1 BU per account)
Resolution 5-2026 BU values (Feb 2026 update). Capacity-based fractional EDUs (e.g. 0.5 for half-units, 0.76 for shared Knollwood Commons meters). Not strict water-use.
Illustrative properties
Real properties picked from the distribution to show how each allocation model treats different kinds of customers. All bills are revenue-neutral $/Q.
How closely does the Feb 2026 EDU table follow its stated rule?
The Board-adopted methodology assigns BUs as roughly ceil(gpd ÷ 150) with a minimum of 1 BU per active account. Across 165 accounts with usage data:
Dollar amounts use the revenue-neutral rate for the NEW model ($162.00/BU/Q). Deviations are against the stated ceil(gpd/150) rule and could indicate either intentional overrides documented elsewhere or data-entry errors that survived adoption. The most extreme single anomaly is acct 74065 (a Village Hall sub-meter): 61 gpd → rule says 1 BU, adopted table assigns 6 BU. Toggle Show anomalies only on the table below to inspect each one.
Per-account impact
Existing (pre-2026) → New (Resolution 5-2026), revenue-neutral. Negative (green) = property would pay less; positive (red) = property would pay more.

1 BU = 150 gpdin the Village's current convention. Each model's per-BU rate is scaled so total annual O&M revenue stays constant — the comparison shows redistribution only, not a rate increase. Source: data/sources/edu_table_extracted.csv. Calculation: analysis/build_bu_allocation.py.
