Illustration on How to Create Water Efficiencies in the Home

A) WATER METER Subsurface with grade-level display; wireless with leak detection and pressure regulator B) RAINWATER COLLECTION Cistern, filter, irrigation control; overflow and filtered matter to storm drain C) STORMWATER DRAINAGE Collect rainwater from roof/gutter system for irrigation; also contains runoff on site versus storm drain D) HOT-WATER RECIRCULATION Motion detector– or manual button–activated recirculation (all bathrooms) E) BATH FAUCETS 32% potential water savings per EPA WaterSense standard; also a greywater source F) SHOWER 20% potential water savings with EPA WaterSense-qualified low-flow showerheads; also a greywater source G) WATER MONITOR Real-time use via PC per water meter; also leak detection and irrigation control H) TOILET 20% potential water savings with 1.28-gpf models vs. 1.6-gpf, per EPA WaterSense standard; greywater supply eliminates use of potable water

M) DISHWASHER 30% water savings with Energy Star–qualified models N) CLOTHES WASHER 33% potential water savings with Energy Star–qualified models; also a potential greywater source O) LEAKS (OUTDOOR AND INDOOR) Average 14% of annual householdM) water use (7,900 gallons per year) P) PLANTS Native and drought-tolerant; grouped by similar irrigation needs; watered by drip irrigation Q) TURF AREAS No more than 40% of lot; native and drought-tolerant; watered by rotating spray heads R) IRRIGATION SYSTEM Smart controls; weather-based and/or soil sensor S) PERMEABLE AREAS Permeable pavers on sand bed reduce stormwater runoff from the site T) POOL COVER Pool/spa cover to reduce evaporation
