Low-flow fixtures and water-efficient appliances
Installing low-flow fixtures and aerators saves water and money. Aerators for faucets and showers require an initial capital investment, but they often pay back the investment in less than a year, especially when they are used often. Many utilities and city governments offer incentives to purchase and install low-flow fixtures. Contact your utility to learn more about these programs. For information on water use efficiency, see New Mexico’s Water Conservation Guide for Commercial, Institutional and Industrial Users.

Low-Flow Fixtures Save Money: Corporate Examples
The Port Authority of New York and New Jersey upgraded restroom facilities at LaGuardia Airport to increase the efficiency of toilets, faucets, and showers. It installed a leak detection system, ultralow-flow toilets, high-efficiency aerators for faucets, and flow restrictors on showerheads. These improvements yield annual water savings of almost $160,000, after an initial capital cost of only $90,000. Case Study
The Veterans Affairs Hospital in Portland, Oregon, performed a water audit and implemented a variety of water-saving measures, including low-flow toilets, faucets, and showers. Savings from these low-flow fixtures amounted to more than $50,000 per year. Case Study
