Rose Valley Water Treatment Plant

 What's new and coming soon

Updated: Feb. 25, 2026:

A reminder for Rose Valley Water Treatment Plant Service Area customers about planned, ratepayer-approved utility bill adjustments starting in April 2026:

• No change occurred on your January bill, which covered the last quarter of 2025.
• For the first quarterly bill of 2026, being sent in April, you will notice:
  • We have removed $37.50 from the RV Residential Flat Rate; this amount represents the cost per parcel for the Rose Valley Water Treatment Plant and Connecting Transmission Mains Project.
  • The RV Residential Flat Rate increased by $1.80 to cover operational costs for 2025 and projected into 2026.
    • In 2026, the RV Residential Flat Water Rate will be $215.14 - $37.50 + $1.80 = $179.44.
  • The $37.50 that is being removed from quarterly utility bills will be transferred to an annual parcel tax to appear on property taxes starting in May.
    • The parcel tax will be $168.89, which is equal $37.50 X 4, plus $18.89.
      • The original estimated parcel tax amount was $181, but the amended amount of $168.89 reflects the Municipal Finance Authority interest charge at the time of borrowing and also accounts for additional parcels added to the system.
    • The parcel tax does not apply to those who prepaid their share.
