What's new

Updated: June 15, 2026:

Planned, ratepayer-approved adjustments in 2026:

  • No change occurred on your January bill, which covered the last quarter of 2025.
  • For 2026 quarterly bills, the first being sent in April:
    • We removed $37.50 from the quarterly RV Residential Flat Water Rate for the per parcel share of the Rose Valley Water Treatment Plant and Connecting Transmission Mains Project.
    • The quarterly RV Residential Flat Rate increased by $1.80 to cover actual operational costs for 2025 and forecast for 2026.
    • In 2025, the quarterly RV Residential Flat Water Rate was $215.14.
    • In 2026, the quarterly RV Residential Flat Water Rate is $179.44 ($215.14 - $37.50 + $1.80).
    • The $37.50 removed from quarterly utility bills has been transferred to an ***annual parcel tax; property taxes notices will be mailed in late May.
  • The ***annual parcel tax will be $171.89, which is equal $37.50 X 4, plus $21.89 for interest.
    • The original estimated parcel tax amount was $181 in 2025; final calculations confirmed the amount to be $171.89 to account for Municipal Finance Authority interest at the time of borrowing and additional parcels added to the system, as of March 15, 2026.

***The $171.89 annual parcel tax does not apply to those who prepaid their share.
