Kohler has developed the Ingenium flushing system a gravity-fed, siphon-jet system with all internal components designed to operate concurrently to make the most efficient use of 1.6 gallons of water. These toilets provide flushing performance that is comparable to Kohler's previous 3.5-gallon models. By using only 1.6 gallons of water per flush, the Ingenium flushing conserves up to 11,000 gallons of water per year for a family of four.
Kohlers Cimarron Comfort Height toilet features Class Five technology to ensure a powerful flush. The commercial-grade toilet, designed for both residential and commercial use, offers chair-height seating, strong gravity-fed flushing power with a 3 1/4'' flush valve, and the option of a 1.6 or 1.4 gallon flush. Over one year a family of four can save over 2,000 gallons of water by using the 1.4-gallon setting instead of the 1.6 industry standard.
Chosen as the EPA’s WaterSense Partner of the Year for two years in a row, Kohler has several new products designed to optimize water savings. For applications where a waterless urinal might not be appropriate, the Bardon 1⁄8 gallon per flush urinal can help both new construction and renovated commercial projects earn LEED points in the Water Efficiency category. Also new, Kohler’s Katalyst showerhead features an optimized sprayface to minimize wasteful overspray, a new internal waterway design, and an innovative air-induction system that gets the most out of every drop.
Invented by a plumber, the HydroRight dual flush converter is designed to simply drop-in and attach to the existing flush valve without the use of tools, reducing installation time and effort. HydroRight can reduce water usage by up to 70% with its Quick Flush option, saving a family of four more than 10,000 gallons of water per year by selecting from a full or reduced flush.
Boasting an impressively low 0.8 gallons-per-flush rate, Stealth uses 37% less water than typical 1.28 GPF high-efficiency toilets. Using a patented air-water vacuum-based flushing system rather than a mechanical assist, the low-maintenance Stealth performs efficiently under a variety of water-pressure conditions.
Rheem Water Heating
The Marathon non-metallic thermal storage tank from Rheem is designed to provide high efficiency and low operating costs, whether used with solar water heating, a geothermal heat pump, or an indirect water heating (hydronic) application. The seamless inner tank is insulated with 21⁄2'' of poyurethane foam, and is wrapped in fiberglass, making it impervious to rust and corrosion.

January 2008 updated
Sloan Valve Company's Water Conservation Division has numerous plumbing systems that are designed to conserve water and/or energy, while delivering reliable performance.
Solis is an electronic, solar-powered faucet that operates via ambient lighting. Solis features an integrated-power-plant storage cell that transforms light from any source into electrical energy. Batteries provide back-up energy and last several years. The single-hole faucet comes standard with integral temperature control, a 0.5-gallon-per-minute aerator to regulate water flow, and an electronic sensor for ³hands-free² operation that turns water on and off automatically.
Sloan's complete line of manual and electronic Flushometers also incorporate features that conserve water. Sloan's newest manual Flushometer, the UPPERCUT Flushometer with its patent-pending dual-flush handle, enables users to choose from two water-conserving flush options: Either tilt the handle up to flush liquid waste with a 1.1-gallon flush, or push the handle down for a standard 1.6-gallon, low-consumption flush. The handle has an antimicrobial coating to protect against germs and is colored green to signify it is an environmentally friendly fixture. On other Flushometers in the Sloan product line, features such as the non-hold-open handle and no external volume adjustment ensure they remain low water- consumption fixtures.
Sloan Valve Company has introduced a new series of High-Efficiency Urinals (HEU) that utilize only one pint of water to flush. The new Sloan HEU systems combine the vitreous china fixture with either a manual Royal Flushometer or from several battery-powered and hardwired sensor-operated models for automatic, hand-free flushing. Also known as fractional-flush urinals, the new HEU¹s provide effective, low-maintenance flushing in public restrooms while reducing water consumption by as much as 88 percent.
Available in three styles, Syndecrete sinks fit standard cabinet bases and are available in 37'' x 23'' or 31'' x 23'' sizes. The sinks are made of lightweight Syndecrete, a cementitious composite and solid surfacing material that uses natural minerals and recycled materials as its primary ingredients. The sinks can be sanded and skim-coated and feature a solid 4'' lip rarely seen in pre-cast concrete products. Recycled carpet fibers help keep the product lighter in weight than ordinary concrete.
Tapmaster, a Calgary-based manufacturer of hands-free faucet controllers, offers the Euro foot-activated model that utilizes water pressure in existing water lines as the method of activation. Besides offering a battery-free and hands-free solution, the control allows users to quickly and hygienically turn on the tap at the temperature and flow rate they’ve set, saving energy and water.
Toto’s 1.28 gpf High Efficiency Toilets, 0.5 gpf High Efficiency Urinals (left), and EcoPower 1.28 and .5 gpf sensor flush valves can achieve a 30% reduction over baseline water use in commercial buildings in the LEED program. While bodysprays aren’t equated with water savings, Toto’s new Gyrostream bodysprays (right) are claimed to be “luxury products with a social conscience,” consuming 1.0-gallons per minute, or 53-60% less water than common body sprays.
July 2011 updated
Using only one pint of water per flush, TOTO’s new ultra-high-efficiency urinal with EcoPower exposed-flush valve can save 75 percent more water than a traditional one-gallon-per-flush unit. The one-pint urinal features an organically shaped, ADA-compliant design that occupies less wall space than traditional urinals. Like all products in the EcoPower line, the .125 gpf EcoPower sensor-flush valve uses flowing water to power its electronics, not batteries.
VitrA¹s 1.2 gpf high efficiency toilet (HET) saves 25 percent more water annually by reducing the amount of clean water each time it is used. Despite the lower flush volume, the toilet performs as a traditional 1.6 gpf toilet.
HousePure Whole-House Water Filtration System uses carbon made from coconut shells along with a media guard featuring nearly five lbs. of KDF-55 bacteriostat to make filtered water available at every faucet and appliance in a house. The system filters the water without salt or caustic chemicals, which can harm the environment.
Watermark¹s SH-1.5ADP showerhead adapter reduces water flow to 1.5 gallons per minute while giving the user the same feeling as using a 2.5 gallons per minute showerhead. Available in standard, designer, and exotic finishes.
Using the Aquia dual-flush toilet can save up to 7,000 gallons of water a year for the average family of four by using a standard flush for solid waste and a lower-volume flush for liquid and paper.
