municipal corporations; water supply; rates

Plain English Breakdown

The bill text contains conflicting or unclear phrasing in Section A regarding rate options (e.g., 'which that'), but the intent appears to be setting four specific pricing tiers.

HB2328: Water Rate Rules for Municipalities

This law stops certain cities in large counties from charging higher water rates to people living outside city limits than they charge residents inside the city, and sets rules for how much one municipality can charge another.

What This Bill Does

• Prohibits municipalities in specific counties with populations between one million and four million from charging a higher water rate to residents living outside their boundaries compared to those living inside.
• Sets limits on the rates a municipality charges when providing water to another municipality, requiring them to be equal to or less than resident rates or other agreed-upon benchmarks.
• Allows existing surcharges adopted before July 1, 1986, to remain in place if they did not exceed thirty percent of the rate charged to residents at that time.

Who It Names or Affects

• Municipal corporations located in counties with a population greater than one million but less than four million.
• Residents who live outside the boundaries of these specific municipalities and receive water service from them.
• Other municipalities that purchase water supply services from larger municipal corporations.

Terms To Know

Municipal corporation

A city or town government with the legal power to operate public utilities like water systems.

Corporate limits

The official geographic boundaries of a city or town where its laws and services apply directly.

Limits and Unknowns

• This law only applies to counties with populations between one million and four million people.
• The text does not specify which Arizona counties currently meet the population requirement for this rule.
• The official status shows no effective date, so it is unclear when these rules officially begin.

wastewater business (
