Mulching is an essential element of a water-efficient garden. Avoid changing gardens during summer when more moisture is lost from disturbed soils and it is difficult for new plants or lawns to survive. Water use from year to year is heavily influenced by the weather. Water on the leaves evaporates easily and can lead to scorching. Note: There are no per capita residential water use data for 2007 because data for the Municipal Water and Wastewater Survey were not collected that year. Lawns consume up to 90% of water and most of the energy used in most gardens. Water drains away rapidly and they are low in nutrients. They are light coloured, have little or no smell. Note: Exemptions are in place for certain businesses and functions; and in all cases, freshly laid sod and newly planted shrubs and trees are exempt from such restrictions for a four-week period. They also take the most time and money to maintain. Swimming pools are major outdoor water users. The greater particle surface area of finer soils gives them a greater capacity to hold water. Incorporating native plants into the garden provides habitat and food for birds and insects. In some urban and suburban areas in the Southwest US, outdoor water use at home can reach up to a whopping 60 percent of all home water use. Long, slow soakings that allow water to penetrate to a depth of about 15cm encourage a deeper, more hardy root system. This can be prevented by less frequent watering. Reticulated drip systems are preferable. Outdoor Water Use in the United States Reduce Your Outdoor Water Use. Aerate the lawn and switch to the car wash for a few months. − Victoria, www2.smartgardenwatering.org.au/, Smart Approved WaterMark. Water early in the morning or evening as this allows water to penetrate before it evaporates. Clay soils ball easily and range in colour from white to red or dark brown. Vegetable gardens produce low-cost food for the household and save on ‘food miles’. Hardy, deep rooted plants can help break up poor soils and adding composted organic matter encourages microbial activity and worms to improve soil condition and moisture retention. No matter where people live, it’s important to think about outdoor water conservation, especially in lawn care. Based on the data overall, greater conservation efforts in landscape irrigation are crucial for Texas residents if water demands are to be met in the 21 st century. Less frequent, deep soakings train plant roots to grow down into the soil and increase the drought tolerance of plants. Maintaining a green lawn can be a massive drain of water – irrigating a 1,000 square foot lawn with just a … This is especially concerning considering that no section of the country is immune from drought or water scarcity and state water managers anticipate water shortages in 40 of 50 states over the next 10 years. A diluted spray of the liquid drained from your composting worm farm (or purchased from a commercial vermiculture operation) is ideal fertiliser. The best car wash in terms of water use is a self-service car wash. Use alternative water sources, such as rainwater or greywater, for high water-use plants. They use the least amount of water because of their high-pressure hoses and easy-to-turn-off pistol grips. Outdoor water use accounted for 64% of the total water use by households. A combination of gypsum, sand and composted organic matter produces the best results in clay soils. An overfilled swimming pool can lose more water through splashing. Swimming pool covers significantly reduce evaporative losses and can save 11,000–30,000L of water a year. Install alternative water supplies such rainwater tanks and greywater systems (see Wastewater reuse). For example, the arid West has some of the highest per capita residential water use because of landscape irrigation. If you run the sprinkler three times a week during a 90-day billing cycle, you will … They hold and drain water well and provide good levels of nutrients. A well-managed yard not only uses less water, it can also significantly cut down on downstream water pollution from using too much fertilizer and pesticides. By Matt Carty Global News. GRACE Communications Foundation. About half of single-family residential water use is outdoors, and a hot, dry year can mean customers use more water than usual. More than half of that outdoor water is used for watering lawns and gardens. Domestic water use includes indoor and outdoor uses at residences, and includes uses such as drinking, food preparation, bathing, ... For some States, these coefficients are county-specific averages derived from observed residential water use and population estimates in nearby areas served by public suppliers. A simple test to identify soil type is to take a handful of soil from the garden and add just enough water to mould it into a ball. Efficient Water Use Outside the Home Water Friendly Gardening. RESIDENTIAL END USES OF WATER Prepared by: Peter W. Mayer and William B. DeOreo Aquacraft, Inc. Water Engineering and Management 2709 Pine St. Boulder, CO 80302 How Americans use water depends on where they live.Those who live in desert regions, including the southwestern states, might use the majority of their total residential water consumption for outdoor irrigation. High water-use — Lawns, most vegetables, fruit trees, exotic shrubs like azaleas and camellias, flowering herbaceous annuals and many bulbs, Medium water-use — Hardy vegetables like pumpkins and potatoes, hardy fruit trees and vines like nut trees and grapes, many herbs, some exotic shrubs, most grey or hairy leafed (tomentose) plants, roses and daisies, Low water-use — Most Australian natives including banksias, grevilleas and eucalypts; succulents and cacti, olive trees and some exotic ornamentals such as bougainvillea. Drip irrigation is the most efficient system. However, since the value (300 gpd) given through the Effective Use of Reclaimed Water Demonstrated to Water Demand report included having rain sensor shut devices and the flow rate of water used to irrigate doesn’t change based upon water savings, the percent (76%) unsaved was factored back into the formula to acquire the quantity of water used without a rain sensor. Further reduce water use outdoors by choosing products and services labelled with a Smart Approved WaterMark. Many people across the nation water lawns during dry spells and droughts, drawing from already strained water supplies. Running a typical sprinkler from a standard garden hose (5/8”) for one hour uses about 1,020 gallons of water; if you run it three times per week, that is about 12,240 gallons per month. In 2010, the city of Tucson had residential water usage rates closer to the U.S. than to the state of Arizona, with 94 gallons per capita per day (GPCD).

Occasional deep soakings train plant roots to grow down into the soil and increase drought tolerance. entities, released an in-depth study of indoor and outdoor water use entitled The Residential End Uses of Water (Mayer and others 1999). Test soil from various sites and from different depths in the garden. At home, washing the car (or dog) on the lawn prevents water and detergent flowing down the drain. Other outdoor water uses and indoor water use was also evaluated. Use a broom instead of a hose to clean paths and the outside of buildings. Paved areas increase heat radiation and water runoff from the site. Instead, ditch the car and carpool, walk, ride a bike or take public transportation. Create garden beds or spread mulch in areas used infrequently or where grass grows poorly. Covered pools save water and energy, and they save dollars, too. Reticulated systems control drip feeding for maximum efficiency. Hand-held watering could be more efficient than a poorly designed automatic watering system. Customers who conserve water get our lowest rates based on our actual costs to provide the service to you. Mulching limits weed growth and can improve soil conditions (depending on the type of mulch). Soil wetting agents allow water to penetrate dry soil surfaces and prevent runoff; water crystals help store water in the soil. There are many easy ways to reduce outdoor water use, save money, time and effort, and benefit the natural environment. Minimise paving of outdoor areas as this increases heat radiation and water runoff from the site. It may be possible to obtain rebates on water efficient garden equipment. Install soil moisture sensors that trigger cut-off switches when it rains and adjust watering duration according to soil moisture levels. Introduction.

Lawns have a limited ability to take up the nutrients from detergents. Reducing lawn area is the easiest way to save water. Heated pools use even more water, because the energy used to heat a pool would most likely come from a thermoelectric power plant. Soil wetting agents allow water to penetrate deeply into soil. This encourages a deeper root system and the longer grass blades shade the soil, reducing evaporation. By 2015, Tucson’s water usage had dropped below the U.S. water usage rate. It returns your waste to the soil and plants. Before mulching, clear weeds, break up the soil crust and water the area. Nationally, outdoor water use accounts for 30 percent of household use yet can be much higher in drier parts of the country and in more water-intensive landscapes. Dry fertilisers take up some water from the soil and can raise salt levels. Saving water saves money and energy. Currently, 65 percent of Denver Water’s single-family residential customers are at or below this level.

Nationwide, landscape irrigation is estimated to account for nearly one-third of all residential water use, totaling nearly 9 billion gallons … Make use of organic food waste by using a home composting system or worm farm to supply natural soil conditioner and fertiliser — and reduce waste going to landfill. This is a serious concern considering the region’s primary water sources like the Colorado River and Sierra Nevada Mountains are already over-allocated and, during times of drought, can be stretched very thin. Did you know that residential outdoor water use across the United States accounts for nearly 9 billion gallons of water each day, mainly for landscape irrigation? Remember: Saving water saves energy, too! A home incorporating whole-of-house water design collects rainwater to use internally and uses it a second time for greywater irrigation. Water only when the lawn is showing signs of stress. Over the course of a year, that could add up to 30,000 gallons (and a high water bill) if it is refilled each year. Humectants, or moistening agents, attract moisture from air spaces in the soil and are particularly effective in sandy soils. 1. to monitor consumption at 1,188 residences spread across 12 … Many other Australian native plants have evolved to cope with very little water. Wash the car with a spray gun that has a trigger control. Generally speaking most water is used internally in toilet flushing, and in laundries, showers and baths, which can be used as greywater for garden irrigation.

Check with your local natural resources or catchment board particularly in outer urban or country zones and near conservation areas. The average American family uses 320 gallons of water per day, about 30 percent of which is devoted to outdoor uses. Since outdoor water use is often the largest component of residential water use the comparison focused on the amount of irrigated landscape reported by the survey respondents. Cars use water in other ways besides car washes. Essentially, we need just five litres or so of water per person per day to live. Minimise outdoor water use by choosing plants that are appropriate for local growing conditions and by including low water use areas in the garden design through the use of indigenous plants or low water use species (see Outdoor water use). Washing a car can help preserve its life, but it takes a lot of water – about 100 gallons, on average – to get a car clean if it’s washed at home with a hose. Sandy soils drain rapidly; clay soils hold water but make it difficult for many plants to grow; loam soils are between the two. Residential Water Rates. All Rights Reserved. Replace lawn areas with porous paving, pebbles or drought-tolerant ground covers such as prostrate grevilleas, snake vine (Hibbertia scandens) or myoporum. Add gypsum at the rate of 0.5–1.0kg/m2. The group reviewed water requirements for a variety of landscape types (xeric, bluegrass, rock and mulch) and used that data to determine that 12 gallons of water per square foot of landscape annually is an efficient outdoor benchmark. Some exotics from South Africa, California and the Mediterranean also cope well with limited water. Do not allow organic mulch to touch woody plant stems and trunks or it may cause collar rot and kill the plant. Plant trees to create natural shade and windbreaks to reduce evaporation. Residential water use (also called domestic use, household use, or tap water use) includes all indoor and outdoor uses of drinking quality water at single-family and multifamily dwellings. Lawns have a limited ability to take up the nutrients from detergents. It delivers water to the roots of individual plants and minimises evaporation and wind drift. It takes a lot of water to make gasoline – approximately one to 2.5 gallons of water for one gallon of gasoline – which means that unnecessary driving trips waste water. Loams are best for plants.
