Overview

Restricts
certain municipal corporations from charging residents who live outside the
boundaries of a municipality from being charged a higher rate for water than
residents living within the boundaries of the municipality.

History

Current law allows municipal ownership of public utilities to
engage in any business or enterprise which may be engaged in by persons by
virtue of a franchise from the municipal corporation, and may construct,
purchase, acquire, own and maintain, within or without its corporate limits,
any such business or enterprise. This includes engaging in a domestic water or
wastewater business (
A.R.S. � 9-511
).

�Municipalities are prohibited from increasing rates, fees or
service charges without:

a)

preparing
a written report or supplying data supporting the increased rate or rate
component, fee or service charge;

b)

adopting
a notice of intention by motion at a regular council meeting to increase water
or wastewater rates or rate components, fees or service charges;

c)

set a date for a public hearing on the proposed increase that
shall be held at least sixty days after adoption of the notice of intention;
and

d)

publishing
a copy of the notice of intention showing the date, time and place of the
hearing one time in a newspaper of general circulation within the boundaries of
the municipality not less than twenty days before the public hearing date (
A.R.S. �
9-511.01
).

Provisions

1.

Prohibits a
municipal corporation, in a county that meets specific population criteria,
that provides water to residents who live outside the boundaries of the
municipality that the municipal corporation serves from charging a rate for

than the rate for water service within the boundaries of the municipality.
