  2. Water efficiency - Wikipedia

    en.wikipedia.org/wiki/Water_efficiency

    Water efficiency is the practice of reducing water consumption by measuring the amount of water required for a particular purpose and is proportionate to the amount of essential water used. [ 1 ] [ 2 ] Water efficiency differs from water conservation in that it focuses on reducing waste, not restricting use. [ 3 ]

  3. Low-flow fixtures - Wikipedia

    en.wikipedia.org/wiki/Low-flow_fixtures

    Switching to water-efficient fixtures is a smart way to save water, reduce your utility bills, and support environmental sustainability. [16] A reduced flow showerhead meeting EPA's WaterSense standards must demonstrate use of no more than 2.0 GPM.

  4. EPA WaterSense - Wikipedia

    en.wikipedia.org/wiki/EPA_WaterSense

    EPA poster publicizing WaterSense products. WaterSense is a program sponsored by the U.S. Environmental Protection Agency (EPA), designed to encourage water efficiency in the United States through the use of a special label on consumer products. [1]

  5. Well test - Wikipedia

    en.wikipedia.org/wiki/Well_test

    A perfectly efficient well, with perfect well screen and where the water flows inside the well in a frictionless manner would have 100% efficiency. Unfortunately well efficiency is hard to compare between wells because it depends on the characteristics of the aquifer too (the same amount of well losses compared to a more transmissive aquifer ...

  6. Water-use efficiency - Wikipedia

    en.wikipedia.org/wiki/Water-use_efficiency

    leaf level : photosynthetic water-use efficiency (also called instantaneous water-use efficiency WUE inst), which is defined as the ratio of the rate of net CO 2 carbon assimilation (photosynthesis) to the rate of transpiration or stomatal conductance, [1] then called intrinsic water-use efficiency [2] (iWUE or W i)

  7. Runoff curve number - Wikipedia

    en.wikipedia.org/wiki/Runoff_curve_number

    These consist chiefly of soils with a layer that impedes downward movement of water or soils with moderately fine to fine textures. These soils have a slow rate of water transmission (final infiltration rate 0.05–0.15 in (1.3–3.8 mm) per hour). HSG Group D (high runoff potential): Soils with very slow infiltration rates when thoroughly ...

  8. Energy factor - Wikipedia

    en.wikipedia.org/wiki/Energy_factor

    The energy factor metric only applies to residential water heaters, which are currently defined by fuel, type, and input capacity. [5] Generally, the EF number represents the thermal efficiency of the water heater as a percentage, since it is an average of the ratio of the theoretical heat required to raise the temperature of water drawn to the amount of energy actually consumed by the water ...

  9. Residential water use in the U.S. and Canada - Wikipedia

    en.wikipedia.org/wiki/Residential_water_use_in...

    End uses of water for households in the U.S. in gallons per household per day and percent of indoor use [1]. 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. [2]
