It's typical that water use for irrigation averages more than 50% of total residential consumption. Clearly, addressing the outdoors is as important as what you do with WaterSaver plumbing fixtures indoors. Here's how:
WATER SMART: Irrigation systems should include separate zones to accommodate different watering requirements, drip irrigation for plant beds, and rotating sprinkler heads for turf areas. Avoid duplicate coverage and watering paved areas and buildings. Surface runoff can be reduced by keeping the precipitation rate from sprinklers below the soil’s infiltration rate, and establishing different zones for the tops and toes of slopes. Over watering is a major problem mostly due to error in setting and maintaining timer-based controllers. While the cost of a sophisticated system will depend on the number of zones and specific features, it isn’t necessarily steep. Check the testing and performance summaries and technical reports on a number of systems at (www.irrigation.org). On small sites, or on sites that have hardscaped areas that don’t require any water, micro-irrigation is an option. These are low-pressure systems that spray, mist, sprinkle, or drip water close to a plant’s root zone through plastic hose lines or small emitters. These systems lose little water to evaporation, wind, and runoff, and they also can be used within multi-zone designs.
