AMWUA Targets Tax on Water Conservation Rebates | The Locally Times

The association, representing 3.7 million residents, argues the tax undermines conservation as Lake Mead’s water level sits at 33% capacity.

The Arizona Municipal Water Users Association (AMWUA) has identified the taxation of water conservation rebates as an impediment to efficiency efforts, signaling a push for policy change. AMWUA is an association of ten large municipalities in Maricopa County, including Phoenix and Scottsdale, that collectively serve 3.7 million people—more than 50 percent of Arizona’s population. According to a February 16, 2026, posting on its website, the organization is working to achieve tax parity for water conservation rebates. The association frames water security as the essential foundation for the state's economic growth, a foundation it argues is put at risk by policies that disincentivize conservation. ## A Region Facing Severe Shortages The push for conservation incentives comes as Arizona faces a severe water crisis. Data from AMWUA’s online news room indicates regional water supplies are under pressure. As of early January 2026, water levels at Lake Mead were at 33 percent of full capacity. Lake Powell, another critical reservoir in the Colorado River system, was at 27 percent of its capacity after its water level dropped 36 feet in a single year. AMWUA’s public documents attribute these conditions to drought, climate change, and the over-allocation of the Colorado River. The association’s position suggests that encouraging residents to adopt water-saving technologies through rebates is a key strategy for managing these challenges, identifying Colorado River shortages and water storage as critical issues for the region. ## Municipal Systems and Policy Gaps The member cities represented by AMWUA manage complex water systems. Phoenix Water, for example, delivers water to 1.6 million residents through 7,000 miles of water lines. Scottsdale Water delivers an average of 61 million gallons of water daily. These municipalities rely on a combination of water sources, including the strained Colorado River, to serve their residents and support the regional economy. While AMWUA’s position against taxing rebates is explicit, the organization’s public documents do not identify which government agency is responsible for the tax policy. The records do not specify whether the tax is a state or federal mandate, nor do they detail the specific statutes that authorize it. The documents also do not provide an estimate of the financial impact on residents who receive rebates or the total revenue collected from the tax. No documents containing a justification for the tax from any legislative body or revenue agency were included in the association's postings.
