Community Water-Saving Education Initiatives

Water conservation aims to sustainably manage the natural resource of fresh water, protect the hydrosphere, and meet current and future human demand. Water conservation makes it possible to avoid water scarcity. It covers all the policies, strategies and activities to reach these aims. Population, household size and growth and affluence all affect how much water is used. (EPA Water Resources)

Although the terms "water efficiency" and "water conservation" are used interchangeably they are not the same. Water efficiency is the improvements such as the new technology that help with the efficiency and reduction of using water. On the other hand, water conservation is the action of conserving water. In short, water efficiency relates to the development and innovations which help use water more efficiently and water conservation is the act of saving or preserving water. (USGS Water Resources)

Aims in water efficiency

Water conservation is the act of conserving water. Although water conservation was something people were working on it became mainstream for a number of reasons. Those reasons include supply shortages, escalating costs of infrastructure, state and federal legislative mandates, public desire to be "green", and conserving water no longer equals revenue. Supply shortages of what is meant to be a renewable resource is what most people target when using water conservation techniques. (USDA National Agriculture Library)

Strategies

The strategies to improve water conservation have similar characteristics which include having any beneficial reduction in water loss use and waste of resources, avoid any damage to water quality, and improve water management practices that reduce the use or enhance the beneficial use of water. (EPA Environmental Resources)

One of the strategies in water conservation is rainwater harvesting. Digging ponds, lakes, canals, expanding the water reservoir, and installing rain water catching ducts and filtration systems on homes are different methods of harvesting rain water. Many people in many countries keep clean containers so they can boil it and drink it, which is useful to supply water to the needy. Harvested and filtered rain water can be used for toilets, home gardening, lawn irrigation, and small scale agriculture. (University of Minnesota Extension)

Another strategy in water conservation is protecting groundwater resources. When precipitation occurs, some infiltrates the soil and goes underground. Water in this saturation zone is called groundwater. Contamination of groundwater causes the groundwater water supply to not be able to be used as a resource of fresh drinking water and the natural regeneration of contaminated groundwater can take years to replenish. Some examples of potential sources of groundwater contamination include storage tanks, septic systems, uncontrolled hazardous waste, landfills, atmospheric contaminants, chemicals, and road salts. Contamination of groundwater decreases the replenishment of available freshwater so taking preventative measures by protecting groundwater resources from contamination is an important aspect of water conservation. (Penn State Extension)

An additional strategy to water conservation is practicing sustainable methods of utilizing groundwater resources. Groundwater flows due to gravity and eventually discharges into streams. Excess pumping of groundwater leads to a decrease in groundwater levels and if continued it can exhaust the resource. Ground and surface waters are connected and overuse of groundwater can reduce and, in extreme examples, diminish the water supply of lakes, rivers, and streams. In coastal regions, over pumping groundwater can increase saltwater intrusion which results in the contamination of groundwater water supply. Sustainable use of groundwater is essential in water conservation. (EPA Water Resources)

Social solutions

Water conservation programs involved in social solutions are typically initiated at the local level, by either municipal water utilities or regional governments. 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 washing. Cities in dry climates often require or encourage the installation of xeriscaping or natural landscaping in new homes to reduce outdoor water usage. Most urban outdoor water use in California is residential, illustrating a reason for outreach to households as well as businesses. (USGS Water Resources)

One fundamental conservation goal is universal water metering. The prevalence of residential water metering varies significantly worldwide. Recent studies have estimated that water supplies are metered in less than 30% of UK households. Although individual water meters have often been considered impractical in homes with private wells or in multifamily buildings, the US Environmental Protection Agency estimates that metering alone can reduce consumption by 20 to 40 percent. In addition to raising consumer awareness of their water use, metering is also an important way to identify and localize water leakage. Water metering might benefit society by providing a financial incentive to avoid waste in water use. (USDA National Agriculture Library)

Some researchers have suggested that 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. 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 techniques. (EPA Environmental Resources)

New technology poses a few new options for consumers, features such as full flush and half flush when using a toilet are trying to make a difference in water consumption and waste. It is also possible to use/"pollute" the water in stages (keeping use in flush toilets for last), hereby allowing more use of the water for various tasks within a same cycle (before it needs to be purified again, which can also be done in-situ). Earthships often use such a setup. (University of Minnesota Extension)

Problems

Answers to a survey of public perception of water shortages, conducted in 2014, showed that people were not likely to use recycled water for consumption due to fear. However, those who are more educated on water conservation chose the "likely" option to using recycled water. Another survey, undertaken in 2021, found that some people "chose not to choose" due to fear of infection or sickness. Researchers believe people went for the neutral option because they still wanted to choose an "environmentally friendly" option. (Penn State Extension)

Wasting water is the flip side of water conservation, and in household applications, it means causing or permitting water discharge without any practical purpose. Inefficient water use is also considered wasteful. According to EPA estimate, household leaks in the US can waste approximately 900 billion gallons (3.4 billion cubic meters) of water annually nationwide. Generally, water management agencies are reluctant or unwilling to give a concrete definition to a relatively vague concept of water waste. (EPA Water Resources)

However, definition of water waste is often given in local drought emergency ordinances. One example refers to any acts or omissions, whether willful or negligent, that are "causing or permitting water to leak, discharge, flow or run to waste into any gutter, sanitary sewer, watercourse or public or private storm drain, or to any adjacent property, from any tap, hose, faucet, pipe, sprinkler, pond, pool, waterway, fountain or nozzle." In this example, the city code also clarifies that "in the case of washing, "discharge," "flow" or "run to waste" means that water in excess of that necessary to wash, wet or clean the dirty or dusty object, such as an automobile, sidewalk, or parking area, flows to waste. (USGS Water Resources)

Water utilities (and other media sources) often provide listings of wasteful water-use practices and prohibitions of wasteful uses. Examples include utilities in San Antonio, Texas, Las Vegas, Nevada, California Water Service company in California, and City of San Diego, California. The City of Palo Alto in California enforces permanent water use restrictions on wasteful practices such as leaks, runoff, irrigating during and immediately after rainfall, and use of potable water when non-potable water is available. Similar restrictions are in effect in the State of Victoria, Australia. Temporary water use bans (also known as "hosepipe bans") are used in England, Scotland, Wales and Northern Ireland.
