Tucson Water's Zanjero program (Zahn-HAIR-oh, or water manager) program helps residential customers manage their home water use. Customers can request a free individualized survey that gives them tips and information on how to lower water use and water bills.
Tucson Water Zanjeros have extensive training in indoor and outdoor water conservation and efficiency. A Zanjero audit includes checking for excessive water consumption, measuring flow rates of showerheads and faucets, looking for special water uses such as spas, pools, or misting systems, and analyzing the efficiency of an irrigation system. During an audit, new low-flow fixtures, faucet aerators, or other water-saving devices may be provided.
To request a Zanjero water audit, call (520) 791-3242 or email TW_CustomerService@tucsonaz.gov and include your name, service address or account number, and a telephone number to reach you. An adult must be present at the time of the audit.
