HB4100: municipal water providers; notice; rates

Sponsor: Representative Kolodin, LD 3

Committee on Natural Resources, Energy & Water

Overview

An emergency measure that directs a municipal provider that receives water from the Central Arizona Project (CAP) to notify customers as outlined of the potential increase of their water rates as a result of losing 100% of the water provided by the CAP.

History

In 1968, the CAP was established by the Colorado River Basin Project Act to deliver 1.5 million acre-feet of Colorado River to the most populous areas of the state and reduce the use of groundwater for agriculture and other activities. The CAP water is used by cities, water utilities, agricultural districts and Native American communities throughout central and southern Arizona.

In 1971, the Central Arizona Water Conservation District (CAWCD), a special taxing district, was created to provide Arizona a means to repay the federal government for the reimbursable costs of construction and to manage and operate the physical system. The price of water is determined annually by the CAWCD Board of Directors based on projections of energy, operation, maintenance and replacement costs (CAP)(Arizona State Library).
