1.  Water conservation programs are typically initiated at the local level, by either municipal water utilities or regional governments water utilities  Common strategies include public outreach campaigns, tiered water rates (charging progressively higher prices as water use increases), or restrictions on outdoor water use such as lawn watering and car washingoutreach  Cities in dry climates often require or encourage the installation of xeriscaping or natural landscaping in new homes to reduce outdoor water usagexeriscapingnatural landscaping

2.  One fundamental conservation goal is universal meteringuniversal metering  Recent studies have estimated that water supplies are metered in less than 30% of UK households, & about 61% of urban Canadian homes (as of 2001)  U.S. Environmental Protection Agency estimates that metering alone can reduce consumption by 20 to 40 percentEnvironmental Protection Agency  In addition to raising consumer awareness of their water use, metering is also an important way to identify and localize water leakswater leaks

3.  Water conservation efforts should be primarily directed at farmers, in light of the fact that crop irrigation accounts for 70% of the world's fresh water use irrigation  The agricultural sector of most countries is important both economically and politically, and water subsidies are common  Conservation advocates have urged removal of all subsidies to force farmers to grow more water- efficient crops and adopt less wasteful irrigation techniquesfarmersirrigation

4.  Low-flow shower heads sometimes called energy- efficient shower heads as they also use less water  Temperature controlled hot water recirculation valves provide instant hot water (so water is not wasted down the drain waiting for water to run hot at your faucet or shower). This can save an average household up to 17,000 gallons per year  Low-flush toilets : These have a dramatic impact in the developed world, as conventional Western toilets use large volumes of water Low-flush toilets  Dual flush toilets includes two buttons or handles to flush different levels of water. Dual flush toilets use up to 67% less water than conventional toilets Dual flush toilets

5.  Saline water (sea water) or rain water can be used for flushing toilets  Faucet aerators, which break water flow into fine droplets to maintain "wetting effectiveness" while using less water  An additional benefit is that they reduce splashing while washing hands and dishes  Wastewater reuse or recycling systems, allowing: Wastewater reuse  Reuse of gray water for flushing toilets or watering gardensgray water  Recycling of wastewater through purification at a water treatment plantpurification

6.  Rainwater Harvesting Rainwater Harvesting  High-efficiency clothes washersclothes washers  Weather-based irrigation controllersirrigation  Garden hose nozzles that shut off water when it is not being used, instead of letting a hose run Garden hosenozzles  Using low flow taps in wash basins  Automatic faucet automates the use of faucets without the use of hands Automatic faucet  Water can also be conserved by landscaping with native plants  Changing behavior, such as shortening showers and not running the faucet while brushing teeth

7.  Waterless urinals  Waterless car washes  Infrared or foot-operated faucets, which can save water by using short bursts of water for rinsing in a kitchen or bathroom  Pressurized water broom, which can be used instead of a hose to clean sidewalks  X-ray film processor re-circulation systems X-ray  Cooling tower conductivity controllers Cooling tower  Utilization of Lake Water and or Sea Water for Cooling Towers Utilization of Lake Water and or Sea Water for Cooling Towers  Water-saving steam sterilizers, for use in hospitals & health care facilities

8.  For crop irrigation, optimal water efficiency means minimizing losses due to evaporation, runoff or subsurface drainage while maximizing productionevaporationrunoff  An evaporation pan in combination with specific crop correction factors can be used to determine how much water is needed to satisfy plant requirementsevaporation pan  Flood irrigation, the oldest and most common type, is often very uneven in distribution, as parts of a field may receive excess water in order to deliver sufficient quantities to other parts Flood irrigation  Overhead irrigation, using center-pivot or lateral-moving sprinklers, has the potential for a much more equal and controlled distribution pattern Overhead irrigation

9.  Drip irrigation is the most expensive and least-used type, but offers the ability to deliver water to plant roots with minimal losses Drip irrigation  Infiltration basins, also called recharge pits, capture rainwater & recharge ground water supplies Infiltration basinsground water  Use of these management practices reduces soil erosion caused by storm water runoff & improves water quality in nearby surface waterssoil erosionstorm water qualitysurface waters
