One can use water more sustainably through a series of simple, everyday measures. These measures involve considering indoor home appliance efficiency, outdoor water use, and daily water use awareness.

Simple techniques[edit | edit source]

Here are some techniques that require little or no setting up and cause little or no inconvenience, but they will generally save you money, and reduce your water, carbon and air pollution impact:[1]

  • Towel cooking - it's extremely easy. Wrapping a pot in a towel while it's hot is enough; putting in inside a cardboard box is better. An insulated box is better again (but needs a little bit of work to set up). Benefits: Save energy (electricity, gas or wood, depending on cooking method); reduce sticking and burning in the pots; reduce your need to watch the stove.
  • "Air wash" your clothes - hang them up in an airy place when you take them off, and give them plenty of time to lose any odor. A drying rack on the balcony is ideal. A hook on the back of the door works, but not as well (unless there's a breeze hitting it). You could extend the time between washes by 2 or more times. See Clothing. Benefits: Save water and detergent; save effort.
  • Rinse clothes: If you've "air washed" as described and worn a couple of times already, put the clothing in water and soak overnight or all day. Wring out and hang to dry. (Fast drying, using breeze and/or sun, gives a more fresh smell to the clothes. Drying in humid weather without sun or breeze can lead to a less-than-fresh smell.) Benefits: Save detergent, probably save some water as well; save effort.
  • Hibernate or suspend your computer when you're not using it, if you don't want to turn it off. Most modern operating systems allow you to suspend or hibernate and wake up again very quickly - everything is the same as it was, as if you'd never turned it off. Benefits: Save electricity.

If you want minimal effort, but don't mind paying a little bit to be responsible:

  • Call up your electricity provider and switch to 100% green power.

Reducing water use in indoor appliances[edit | edit source]

Housing and commercial buildingsW account for 12 percent of America's freshwater withdrawals.[2]A typical American single family home uses about 70 gallons per person per day indoors.[2]This usage can be reduced by simple alterations in behavior and upgrades to applianceW quality.

Toilets[edit | edit source]

Flush toilets account for almost 30% of residential indoor water use in the United States.[3] Some tweaks can be applied to still reduce water consumption greatly with flush toilets. Another option is to install a type of toilet that doesn't use water at all. For example, composting toilets treat human waste through composting and dehydrationW, producing a valuable soil additive.[4] These toilets feature a two-compartment bowl to separate urine from feces. The urine can be collected or sold as fertilizer. The feces can be dried and bagged or composted. These toilets cost scarcely more than regularly installed toilets and do not require a sewer hookup. In addition to providing valuable fertilizer, these toilets are highly sustainable because they save sewage collection and treatment, as well as lessen agricultural costs and improve topsoilW.

Showers[edit | edit source]

On average, showers are 18% of indoor water use, at 6-8 gallons per minute traditionally in America.[3]A simple method to reduce this usage is to switch to low-flow, high-performance showerheads. These showerheads use only 1.0-1.5 gpm or less. An alternative to replacing the showerhead is to install a converter. This device arrests a running shower upon reaching the desired temperature. Solar water heaters can be used to obtain optimal water temperature, and are more sustainable because they reduce dependence on fossil fuels. To lessen excess water usage, water pipes can be insulated with pre-slit foam pipe insulation. This insulation decreases hot water generation time. A simple, straightforward method to conserve water when showering is to take shorter showers. One method to accomplish this is to turn off the water when it is not necessary (such as while lathering) and resuming the shower when water is necessary.

Dishwasher/Sinks[edit | edit source]

On average, sinks are 15% of indoor water use.[3]There are, however, easy methods to rectify excessive water loss. Available for purchase is a screw-on aerator. This device works by combining water with air thus generating a frothy substance that has more moisture and reduces water usage by half. Additionally, there is a flip-valve available that allows flow to be turned off and back on at the previously reached temperature. Finally, a laminar flow device creates a 1.5-2.4 gpm stream of water that reduces water usage by half, but can be turned to normal water level when optimal.

In addition to buying the above devices, one can live more sustainably by checking sinks for leaks, and fixing these links if they exist. According to the EPA, "A small drip from a worn faucet washer can waste 20 gallons of water per day, while larger leaks can waste hundreds of gallons":[3]When using a sink, being more aware of water usage is a very simple way to use water more sustainably. For instance, when washing dishes by hand, it is not necessary to leave the water running for rinsing. It is more sustainable to rinse dishes simultaneously.

On average, dishwashing consumes 1% of indoor water use.[3]When using a dishwasherW, water can be conserved by only running the machine when it is completely full. Additionally, it can be set to Lowflow setting, in order to use less water per wash cycle. The enzymatic detergentsW available clean dishes more efficiently and more successfully with a smaller amount of water at a lower temperature.

Washing machines[edit | edit source]

On average, 23% of indoor water use is due to clothes washing.[3]In contrast to other machines, American washing machinesW have changed little to become more sustainable. A typical washing machine has a vertical-axis design, in which clothes are agitated in a tubful of water. Horizontal-axis machines, in contrast, put less water into the bottom of the rub and rotate clothes through it. These machines are more efficient in terms of soap usage and clothing stability.

Most of the energy used up by the washing machine goes to warming the water according to Energy Star. Therefore, you must skip the heating setting of the machine and just use it on the cold water setting. This will not only restrict the emission of CO2 but will also maintain your clothes in good condition for long periods. Hot water is responsible for deteriorating the fabric and as a result, the colors of your clothing will appear less vibrant. There is no point in using hot water settings of your washing machines unless you are facing stubborn stains such as oil stains. If you feel that the cold water settings are not getting the job done you can turn back to the warm water settings.[5]

Reducing water use in the garden[edit | edit source]

Homeowner's rain garden (American Rivers Image Library)

There are a number of ways one can incorporate a personal yardW, roofW, and garden in more sustainable living. While conserving water is a major element of sustainability, so is sequestering water.

Most of us, if not all, are guilty of overwatering our front and backyards during the scorching summer months. The reality is lawns need a lot of water, but simple tricks can help conserve precious H20.

Program your sprinkler system to power on at night. Why? During the nighttime, the air is cooler and less capable of absorbing moisture. During the daytime, much of the water evaporates even before it hits the ground.

To ensure that water reaches the roots, leave the sprinkler on for about ten minutes. This step ensures that the soil is wet enough to avoid watering every day. Employing these additional tactics could also come in handy in preserving this precious resource.

A. Collect rainwater

B. Install a drip irrigation system

C. Check your sprinkler regularly (to ensure water is directed on your landscape and not on the sidewalks)[6]

Using plants suited for the region[edit | edit source]

In planning a yard and garden space, it is most sustainable to consider the plants, soil, and available water. Drought resistant shrubs, plants, and grasses require a smaller amount of water in comparison to more traditional species. Additionally, native plants (as opposed to herbaceous perennials) will use a smaller supply of water and have a heightened resistance to plant diseases of the area. XeriscapeW, a system that accounts for endemic features such as slopeW, soil typeW, and native plantW range, can reduce landscape water use by 50 – 70%, while providing habitatW space for wildlife. By planting slopes one can reduce runoffW. Grouping plants by watering needs further reduces water waste.

After planting, placing a circumference of mulch surrounding plants functions to lessen evaporationW. To do this, firmly press two to four inches of organic matter along the plant's dripline. This prevents water runoffW. When watering, consider the range of sprinklers; watering paved areas is unnecessary. Additionally, to conserve the maximum amount of water, watering should be carried out during early mornings on non-windy days in order to reduce water loss to evaporation. Drip-irrigation systems and soaker hoses are a more sustainable alternative to the traditional sprinkler system. Drip-irrigation systems employ small gaps at standard distances in a hose, leading to the slow trickle of water droplets which percolate the soil over a protracted period. These systems use 30 – 50% less water than conventional methods.[7] Soaker hoses help to reduce water use by up to 90%.[8] They connect to a garden hose and lay along the row of plants under a layer of mulch. A layer of organic materialW added to the soil helps to increase its absorption and water retention; previously planted areas can be covered with compost.

In caring for a lawn, there are a number of measures that can increase the sustainability of lawn maintenance techniques. A primary aspect of lawn care is watering. In order to conserve water, it is important to only water when necessary, and to deep soak when watering. Additionally, a lawn may be left to go dormant, renewing after a dry spell to its original vitality.

Reusing grey water and unfiltered roof water[edit | edit source]

Greywater systems function in sequestering used indoor water, such as laundry, bath and sink water, and filtering it for reuse. Greywater can be reused in irrigation and toilet flushing. There are two types of greywater systems: gravity fed manual systems and package systems.[9] The manual systems do not require electricity but may require a larger yard space.[9]The package systems require electricity but are self-contained and can be installed indoors.[9]

A common method of water sequestrations is rainwater harvesting, which incorporates the collection and storage of rain. Primarily, the rain is obtained from a roof, and stored on the ground in catchment tanks. Water sequestration varies based on extent, cost, and complexity. A simple method involves a single barrel at the bottom of a downspout, while a more complex method involves multiple tanks. It is highly sustainable to use stored water in place of purified water for activities such as irrigation and flushing toilets. Additionally, using stored rainwater reduces the amount of runoff pollution, picked up from roofs and pavements that would normally enter streams through storm drains. The following equation can be used to estimate annual water supply:

Collection area (square feet) x Rainfall (inch/year) / 12 (inch/foot) = Cubic Feet of Water/Year

Cubic Feet/Year x 7.43 (Gallons/Cubic Foot) = Gallons/year

Note, however, this calculation does not account for losses such as evaporation or leakage.[10]

Water-saving practices and devices[edit | edit source]

A key component of reducing the reliance on water supply dams is making the process of providing water as efficient as possible. While the minimum amount of water required by the average person for drinking, cooking, bathing and sanitation is considered to be 13 gallons per day, the average person in the United States uses between 65 and 78 gallons of water for those same purposes.[11] According to a study conducted by the Organization for Economic Cooperation and Development, the United States has the highest rate of per capita water consumption among its member countries.[12] Municipalities and industry have the opportunity to reverse wasteful water practices and improve efficiencies by encouraging and/or mandating conservation, while individuals can become part of the solution by implementing conservation practices in their own homes. Techniques for reducing indoor water use include installing low-flow water fixtures such as toilets, shower heads, washing machines and dishwashers; detecting and repairing leaky pipes and fixtures; and implementing educational campaigns to reduce wasteful practices such as running water when washing dishes or brushing teeth. Outdoor conservation can include using water-conserving landscaping methods such as drought tolerant planting and watering in the early morning or evening. While outdoor water consumption is the largest area of residential water use, bathroom fixtures consume the majority of indoor water in most households. The Energy Policy Act of 1992 established a national manufacturing standard of 1.6 gallons per flush for most toilets. By replacing one old toilet with a newer 1.6-gpf model, toilet water use can be reduced by up to 46 percent. The EPA estimates that use of these high-efficiency toilets in new construction projects along with standard replacements will result in a savings of 7.6 billion gallons per day by 2020. Many municipalities are even offering incentives to replace old toilets with high-efficiency versions.[13] The theory behind high-efficiency toilets can be applied to other areas. The average five-minute shower sends 40 gallons of water down the drain. By installing a low flow showerhead or flow restrictor, consumers can save up to 30 gallons per shower.[14] Fixing leaks can also save several thousand gallons of water. A slow-dripping, leaky faucet wastes 5,475 gallons per year.

Xeriscaping has drastically reduced watering (Denver Water, Charles Mann Photography)

To curb outdoor water use, homeowners, businesses, and city planners must find a solution that is appropriate for the climate they live in. One solution is xeriscaping, which is a comprehensive landscaping method that employs drought-resistant and water-efficient gardening techniques in an effort to conserve water. It was developed in response to a severe drought that devastated Colorado in 1981. Instead of using turf and grass, xeriscaping encourages the use of mulch, which is functional for water retention, long-term fertilization and weed control. Drought-resistant plants are planted in groups, according to water needs, in order to utilize irrigation methods efficiently. In addition, placement is based on the optimal amount of sun exposure. Efforts are made to improve the soil, which subsequently allows for better absorption of water.[15] Homeowners who use xeriscape can expect to save a considerable amount of money on both maintenance and water use. Contrary to popular belief, automated sprinkler systems do not save water or money because owners rarely adjust them for weather or humidity variations. Manually operating a sprinkler system or using a hose where watering is needed is much more cost and water efficient.[16]

Many cities and states are undertaking intense conservation efforts to ensure water supplies for their growing populations.

  • California has embarked on a major effort to retrofit toilets. Full implementation could save an additional 400,000 acre-feet per year—the size of a large California reservoir.
  • With continued population growth in the city of San Antonio, Texas, officials have put an emergency aquifer management plan in place with a hotline for reporting incidences of water waste. The city also offers rebates for installing low-flow toilets and high efficiency washing machines.[13]
  • Officials in Mexico City instituted a program to replace 350,000 toilets with newer high efficiency versions that have already saved enough water to supply some 250,000 additional residents.[17]

Water saving basin/toilet idea in Taiwan and Japan[edit | edit source]

One of their space saving ideas could also save us water. Some WC's don't have room for a toilet and a wash basin, so some have the two combined. They have a toilet as per usual, however the lid or top of the cistern, instead of being convex with a button in the middle is concave and has a small tap above it. After flushing the toilet you then rinse your hands in the small sink on top of the cistern, and then this water fills the cistern. You thus end up saving the water that would otherwise have been used to wash your hands, and reuse greywater in a closed system that should be acceptable to the appropriate building/water regulations.[18]

Advantages[edit | edit source]

The alternatives offered above are not new ideas and, in fact, have become commonplace. However, while there are laws mandating the use of high efficiency appliances in new building projects, there are few examples of large-scale efforts or incentives available for upgrades. As evidenced by some of the city and state programs referenced in the sidebar, efforts to increase water efficiency do work and could help fill the demand typically met by a water supply dam, especially in some of the smaller scale water supply systems that can be found in the Northeast and Mid-Atlantic regions of the USA.

Disadvantages[edit | edit source]

Depending on the scope of the project, cost can be a factor when installing new equipment (e.g., low-flow toilets) or replacing dilapidated pipes. There are also social considerations to take into account, such as resistance to low-flow toilets and showerheads because people feel like they are not getting adequate water. The biggest drawback of xeriscaping is the original cost of re-landscaping a yard. In addition, it takes an average of two to three years for the plants to reach full growth. Water conservation methods that rely on behavioral changes such as these may require ongoing educational efforts to maintain water-saving habits.

Costs[edit | edit source]

While the initial outlay for installing water-conserving fixtures can be substantial, these costs can be recovered - often rather quickly - through savings on water, energy and sewage. The Port Authority of New York and New Jersey at LaGuardia Airport implemented water conservation measures by renovating their restrooms. These measures included installing low-flow toilets, showerheads and faucets and implementing a leak detection and prevention program. Total cost for the equipment was $79,276, but they were able to recoup these costs within eight months through water and sewage savings.[19] For an individual looking to take initial steps to make their home more water efficient, rebates and other incentives can make switching quite affordable. New low-flow toilets can start at $61-$80 and go as high as $700.[20] Low-flow showerheads range from $8-$50 depending on the number of features. While xeriscaping can also save water and money in the long run, the initial landscaping costs are not insignificant. For example, the Southern Nevada Water Authority has estimated the cost of converting 1,275 sq. ft. to xeriscape at $2,130. However, they also estimate that costs can be recovered in the first five years, with a savings of $1,500 or more after ten years.[21]

Water-saving practices and devices, case study #1[edit | edit source]

Thanks to concerted citizen action, the Massachusetts Water Resources Authority (MWRA) undertook a coordinated effort to reduce water consumption to below the safe yield of the Quabbin Reservoir – thereby making a plan to divert the Connecticut River into the Quabbin unnecessary. The key to their success was demonstrating the cost and water savings potential of demand control measures, including a domestic retrofit program and a new retail water and sewer charge system. They also identified system leaks and unaccounted for water that were targeted for repair. Because of the consensus work of MWRA and the committee, metropolitan Boston decreased its consumption by 35 percent and was able to avoid additional diversions from the Connecticut River.

Water-saving practices and devices, case study #2[edit | edit source]

As part of their global water stewardship initiative, Unilever Home and Personal Care – USA wanted to demonstrate that conservation measures could have positive economic repercussions. In 1995, Unilever began implementing an extensive water efficiency program at its Cartersville, Georgia plant to prove just that. The company had put all aspects of the plan into effect by 2000, including:

  • Heightened employee awareness of environmental and economic benefits of water conservation;
  • Water reuse in non-contact cooling water, wash water and water from scrubbers and parts washing;
  • Collection and use of rainwater in manufacturing process; and
  • Automatic control of cooling water.

Since implementing this program, Unilever has reduced its wastewater effluent volume by 77 percent at a savings of $20,000 per year for potable water. By downgrading their usage status, they are also saving an additional $85,000 per year in permitting fees. A portion of this savings from the water efficiency program is added to employee bonuses.[22]

Conservation pricing[edit | edit source]

Conservation pricing is a method used to encourage consumers to reduce water consumption and thus reduce or eliminate the need for new or existing dams. It involves creating financial incentives for consumers to use less water, while at the same time not making water supply cost prohibitive for any particular user. The purpose is to expose consumers to the "full costs" of water and discourage waste by targeting their most precious resource: the pocketbook.[23] Municipalities in arid regions have been known to implement conservation pricing in the form of increasing block rates. Block rates are typically tiered for different usage levels so that users pay higher rates as they consume increasing amounts of water. Rates for customers who fall in the upper block can be three times the rates of users in the lower block.[24] Cities like Tucson, Arizona and Edmonton, Canada are creating rate structures that have resulted in the cutting of household water use by 10 to 15 percent.[25] While conservation pricing can be used to reduce residential water consumption, the impacts are more noticeable in the industrial arena because industry uses more water and is normally more likely to obtain volume discounts. A study by Janice Beecher in 1994 found that a ten percent increase in price decreased residential demand by up to four percent and industrial demand by up to eight percent.[23]Experts suggest that rate plans be designed to consider the local population's ability to pay higher prices. While this may involve offering discounts or assistance to low-income families, it could allow for the targeting of highly wasteful industries. Eliminating volume discounts and using increased rates are methods of encouraging industry to implement some of the other conservation techniques discussed in this report.[23]

Increasing block rate pricing structure (New East Consulting Services, Ltd)

Advantages[edit | edit source]

Conservation pricing can reduce consumption without the capital expenditures associated with other water supply strategies. While conservation pricing may not result in the removal of a water supply dam, it is a tool that decisionmakers could adopt to stretch existing supplies and delay or eliminate the need to construct new dams.

Disadvantages[edit | edit source]

While conservation pricing could preserve water resources, there are several institutional and public barriers to implementation. Many water systems are publicly owned and overseen by elected officials subject to the whims of politics. These officials might resist implementing higher prices for fear of retaliation at the voting booth. Setting higher rates could also be constrained by regulatory codes that vary across state and local jurisdictions. For example, at the federal level, the Clean Water Act determines how prices are set for wastewater treatment plants funded under the program.[23]

Costs[edit | edit source]

Capital costs are virtually nonexistent for municipalities looking to implement conservation pricing. Consumers, however, could see their water rates increase as the amount of water they consume increases. See the chart on the preceding page for an example on how these rate structures would work.[26]

Conservation Pricing, Case Study #1[edit | edit source]

From 1986 to 1992, the city of Santa Barbara, California experienced one of the most severe droughts in its history. This coastal community, which derives its water supply from a local aquifer and the Santa Ynez River, was forced to become more resourceful in meeting basic water needs. As part of a comprehensive water supply plan, they developed a desalination plant (discussed later), and increased the water rates three-fold through the course of the drought, switching to an increasing block rate structure in 1989. While it is difficult to separate the impact of conservation pricing from the education campaign and other conservation measures undertaken, water use dropped to 46 percent of pre-drought levels at the height of the drought. Five years after the drought ended, water use still held at 61 percent of pre-drought levels.[27] If water savings such as this could be achieved in other watersheds, smaller, non-essential dams could be removed and the need for new dams diminished.

Where you can go for help on conservation pricing[edit | edit source]

When selecting a new toilet, be sure to consider all of your options. Cheapest may not be best. New and up-and-coming models include composting toilets, dual flush, and flapperless toilets. (Water Saver Home, http://www.h2ouse.org)

Relative cost-effectiveness of water-conserving measures[edit | edit source]

Key points: Retrofitting is expensive; the most appealing options for environmentalists (e.g. rainwater tanks) are not necessarily the most cost-effective ways of conserving water.

The Marsden Jacob report on water supply options for Australian cities states:

Large-scale water conservation measures, such as retrofitting of water saving appliances, does come at a cost. This cost must be weighed against the benefits of the measure. For example, the review of Sydney Metropolitan Water Plan suggests some water conservation measures, such as appliance standards and labelling, may cost very little, while other measures, such as the installation of rainwater tanks may cost as much as $3 per kilolitre – well above the cost of other measures such as recycling.[28]

and:

Structural alternatives to potable water supplies, including stormwater recycling and water sensitive urban design, are typically only cost effective in greenfield situations, where new developments can be designed with water conservation in mind. While greenfield sites represent only a small proportion of the city in any particular year, the growing population will mean that structural changes introduced on a small scale now will dominate the cityscape of the future.[29]

Rainwater tanks: One writer summed up the report's view on rainwater tanks as follows: (Particularly in a drought), "rainwater tanks are pretty useless as well (as dams). Installing enough tanks to make any difference would be far more expensive than building a desalination plant, and next to useless in a continuing drought."[1]

The Marsden Jacob report states:

Rainwater tanks deliver the highest benefit compared with cost in areas that receive consistent rainfall during the year. In areas that receive little rainfall during summer months, such as Perth, rainwater tanks supply relatively little water and at high unit cost with the result that other water sources are typically required to make up the shortfall during the heaviest periods of water use;[30]

Stormwater, according to the report, would be a significantly cheaper source than rainwater tanks, in Australian cities. A third world equivalent might be a simple form of groundwater recharge to capture water runoff from the earth and to recharge the water table, which is then accessible as groundwater.

Greywater systems always have input due to primary uses (e.g. bathing, washing clothes and dishes, and cooking), unlike rainwater systems. In that sense they are ideal for ensuring water supply for secondary uses, such as a garden, during a drought.
