Winchester - Subject to local approval, expands the board of public utilities' jurisdiction to wastewater treatment systems; requires the mayor to serve as a standing member of the board during the mayor's term; creates four-year terms for members; and makes various other changes. - Amends Chapter 34 of the Private Acts of 2019.

HB 2643 restructures Winchester’s utility governance by creating a Board of Public Utilities with five members (including the Mayor as a standing member during their term). It establishes four-year terms for appointed members with rotating expirations, requires City Council approval for appointments and budget decisions, and mandates that utility rates and service charges be reviewed by both the Board and City Council. The bill specifies that utility revenues must cover operational costs, debt payments, system improvements, and a tax-equivalent payment to the city’s general fund, while prohibiting free utility services for city departments. This directly affects Winchester’s local government operations, utility rate-setting, and budget processes for water, wastewater, and electricity systems. The bill requires two-thirds approval from Winchester’s City Council to take effect.
