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
