• Showers emerged as the single largest source of indoor water use. ¬Weve got to get people to shorten their showers,® says study author William DeOreo, president of Aquacraft. ¬Low-flow showerheads [alone] arent doing it.® And while leaks account for 18% of indoor water use, few builders install leak detectors as part of their efficiency package. ¬We need to identify and then interfere with leaks,® DeOreo says.

    EPA Releases New Data

    A new national study reveals the water savings to be had by moving from standard new-home building techniques to high-efficiency practices.

     
  • Netafim. The Techline EZ 12-millimeter dripperline installs above ground using a simple looped system and is hidden under mulch or ground cover. Self-flushing drippers are spaced every 6, 12, or 18 inches for a variety of plant and soil configurations. The dripperline, which is made with recycled polyethylene, features pressure compensation to ensure delivery of equal amounts of water and anti-siphon emitters with root barriers. 888.638.2346. www.netafimusa.com.

    Ground Rules

    Reducing outdoor water use is a top priority. Here’s how to combine design and technology for water-efficient landscaping.

     
  • Bord na Mona. The Puraflo Wastewater Treatment System is a natural system that can be used for both on-site greywater and blackwater recycling. Filtered wastewater from a standard septic system is collected and then time dosed (pumped slowly) to percolate through a peat filter media; the treated effluent emerges as a ¬clear innocuous liquid,® according to the company. The treated water can be used to irrigate lawns, ornamental trees, and shrubs. Other advantages of this system come with leach field preservation and a reduced need for leach field area, allowing the construction of a septic system in challenging locations, such as too small a lot for the house size, poor percolating soils, or close to lakes and streams. 800.787.2356. www.bnm-us.com.

    Second Time Around

    Nearly 50% of potable water delivered to American homes goes down the drains of sinks, showers, and washing machines. Here's how to put that "lightly used" water to work for a second time around.

     
  • Toto. With a flow rate of 1.5 gpm, Upton WaterSense-certified lav faucets use 32% less water than traditional units. The faucet, which features supple, rounded edges and corners for a clean yet cozy feel, includes a 90-degree ceramic-disc valve. It is available in standard-height and tall options. 888.295.8134. www.totousa.com.

    Go With the Flow

    With the advent of WaterSense certification—and manufacturers’ overwhelming response to it, there’s simply no excuse not to specify water-efficient toilets, showerheads, and faucets.

     
  • Awash in Savings

    Today’s dishwashers and washing machines are working hard to save both water and energy without compromising performance.

     
  • Images of a depleted Lake Lanier, Atlantas main water source, came to symbolize the severity of one of the worst droughts in Georgia history. The 20072008 crisis raised the awareness that water shortages are not limited to Southwestern states.

    Water—Now

    We've got a pretty good handle on energy, resource efficiency, and indoor air quality. Now it's time to get very serious about water conservation--before it's too late.
