This document outlines best practices to achieve water efficiency (WE) in buildings by significantly reducing indoor potable water use and employing efficient site water management. It describes vital strategies including the installation of low-flow fixtures, utilizing non-potable water sources, and xeriscaping to minimize irrigation needs. Emphasis is placed on the importance of greywater reuse and monitoring water consumption to enhance environmental well-being. By adopting these strategies, we can lessen the burden on municipal water supplies and promote sustainable water usage.

  1. Water Efficiency (WE) Goals Reduce indoor potable water use for buildings. Use site water efficiently. Reduce process water use. Reduce municipal water supply and treatment burden.

  2. Water Efficiency (WE) Potable water is water meeting quality standard allowing for consumption or use with low risk of immediate or long term harm. xeriscapinga landscaping method that makes routine irrigation unnecessary by using drought-adaptable and low-water plants, as well as soil amendments such as compost and mulches to reduce evaporation. Greywaterdomestic wastewater composed of wash water from kitchen, bathroom, and laundry sinks, tubs, and washers which has not come into contact with toilet waste. Some states and local authorities allow kitchen sink wastewater to be included in greywater. Water balance a comparative measure of the amount of water that flows in and out of a system.

  3. Water Efficiency (WE) Reduce Demand by: Designing sites to minimize or eliminate the need for irrigation Install plumbing fixtures that conserve water Install waterless urinals or composting toilets Reuse captured stormwater or treated graywater to replace potable water

  4. Water Efficiency (WE) Strategies for reducing indoor water use: Install efficient plumbing fixtures: Flush Fixtures, GPF: Low-flow Dual-flush HET Waterless urinal Composting toilet Energy Policy Act of 1992 (EPAct) WaterSense (EPA)

  5. Water Efficiency (WE) Strategies for reducing indoor water use: Install efficient plumbing fixtures: Flow Fixtures, GPM: Low-flow faucets (lavatories) Meter faucets Low-flow showerhead Low-Flow Kitchen faucet Energy Policy Act of 1992 (EPAct) WaterSense (EPA)

  6. Water Efficiency (WE) Strategies for reducing indoor water use: Use nonpotable water: Captured rainwater Treated graywater Cooling tower water Municipally provided reclaimed water Check local code Install submeters

  7. Water Efficiency (WE) Strategies for reducing outdoor water use: Use native and adaptive plants Xeriscaping Efficient irrigation technologies Use nonpotable water Install submeters

  8. Water Efficiency (WE) Overview Monitoring Water Consumption Performance Reducing Indoor Potable Water Consumption Reducing Water Consumption to Save Energy and Improve Environmental Well-Being Practicing Water-Efficient Landscaping In Schools, Use Water-Efficient Processes as a Teaching Tool
