Water and Wastewater Capacity Fee

Water and Wastewater Capacity Fees were adopted and became effective January 1, 2026, under Mesa City Code Section 8-10-13, with a six-month phase-in period on ¾-inch and 1-inch meters.

Effective July 1, 2026, the total full Water and Wastewater Capacity Fees for ¾-inch and 1-inch meter services will be assessed. These Capacity Fees provide funding for capital infrastructure improvements necessary to support Mesa's growing water and wastewater systems.

Capacity fees are a one-time charge for a new or upsized connection to the Mesa water and/or wastewater system. The fee is designed to recover the growth-related portion of the cost of constructing additional water and wastewater system capacity. These fees are assessed to any new customers that require a service connection or existing customers that require a larger service connection.

When the water impact fee ended in 2024, Mesa engaged with Black & Veatch Corporation to explore options to fund future growth-related projects. Black & Veatch had recently completed the Water/Wastewater Integrated Master Plan in 2025, which laid out the funding needs for future water/wastewater capacity. Because the need was primarily for water/wastewater, it was decided to look at a different option, and based on the recommendation of the consultant, the decision was made to propose a capacity fee per A.R.S. §§ 9-511 and -511.01, which applies to water/wastewater services.

This proposal was presented to the City Council at the November 6, 2025, Council Meeting and adopted at the December 1, 2025, City Council Meeting. 

Below are the report prepared by Black and Veatch, frequently asked questions, and the November 6, 2025, Council Study Session Presentation.
