Water conservation Irrigation Systems used to irrigate crops Gravity flow Drip Irrigation* Center pivot* Other options Line canals Irrigate at night Monitor soil moisture Polyculture Organic farming Avoid water-thirsty crops in dry areas Irrigate with treated waste water Import water-intensive crops and meat
Water Conservation Industry and Homes Redesign manufacturing processes to use less water Recycle water in industry Landscape yards with plants that require less water Use drip irrigation Fix water leaks Use water meters Raise water prices
Water Conservation Industry and Homes Use waterless composting toilets Require water conservation in water-short cities Use water-saving toilets, showerheads, and front- loading clothes washers Collect and reuse household water to irrigate lawns and nonedible plants Purify and reuse water for houses, apartments, and office buildings
Water Conservation Removing Waste Current Process: use of fresh water to remove waste Alternative Mimic nature by applying nutrient cycling and use the nutrient rich sludge Ban the discharge of toxic chemicals Waterless composting toilets Convert fecal matter to small, dry, odorless soil-like humus that can be removed and used as fertilizer
