The Alliance for Water Efficiency has released a powerful new conservation planning model that can assist water providers in their conservation planning efforts. The AWE Water Conservation Tracking Tool is a spreadsheet-based software package that can evaluate the water savings, costs, and benefits of conservation programs for a specific water utility. The tool is available for free to all AWE annual members.
Utilities can use the Conservation Tracking Tool in a variety of ways to aid their water resource planning and operations. The tool can help:
- Quickly compare alternative conservation measures in terms of their water savings potential, impact on system costs, and potential benefits to utility customers.
- Develop long-range conservation plans. Construct conservation portfolios containing up to 50 separate conservation program activities.
- Track the implementation, water savings, costs, and benefits of actual conservation activities over time.
- Evaluate a utility’s changing revenue requirement with conservation.
The Tool counts the savings achieved from national plumbing code and appliance standards. For California and Texas, states that have stricter requirements for toilets by 2014, a separate version of the Tool is available that incorporates the new state legislative changes.
As part of the release of the software tool, AWE has teamed with the Chicago Metropolitan Agency for Planning, and the Chicago Department of Water Management to offer a free workshop on water conservation planning using the new tracking tool to be held on September 3, 2009 in Chicago.

The California Energy Commission (CEC) has suspended the proceeding to establish landscape irrigation equipment efficiency performance standards and labeling requirements. The decision to suspend the proceedings was made after the CEC heard testimony primarily on the topic of smart irrigation controllers over a three month period.
In the suspension announcement the CEC said, “After reviewing the available information and submittals…, the Committee has determined that there is insufficient technical data and analyses necessary to substantiate specific standards or labeling requirements for the landscape irrigation equipment defined in the Scoping Order.”
On the subject of performance standards for smart irrigation controllers, the CEC said, “Sufficient information on costs, actual performance, and methods to verify savings is lacking. In addition, recent studies have shown that the use of industry-preferred controllers, or "Smart Controllers", frequently increases water use as well as energy consumption. The only industry accepted test methods available for controllers do not test for water conservation, but rather measure the efficiency of applying adequate amounts of water supplies to landscapes.”
The CEC mandate on irrigation equipment encompasses more than just smart controllers. According to Lorraine White of the CEC, the suspension is not permanent. Once additional funding becomes available, the CEC plans to continue investigating performance standards for other irrigation equipment such as rain and soil moisture sensors. The Alliance for Water Efficiency will continue to report on this important process once the suspension is lifted.
Congressional leaders, government officials, and key water stakeholders gathered on the evening of July 28, 2009 in Washington, DC for a discussion of national water policy issues and for a viewing of the film “The American Southwest: Are we Running Dry?” The event was co-sponsored by a number of national water organizations, including the Alliance for Water Efficiency. Congressmen Markey (D-MA), Blumenauer (D-OR), Costa (D-CA), and Linder (R-GA) were speakers, as were Peter Silva, Assistant Administrator for the EPA Office of Water, Michael Connor, Commissioner of the US Bureau of Reclamation, and Steve Stockton, Director of Civil Works for the US Army Corps of Engineers. A distinguished panel of stakeholders discussed the issues and the need for developing a comprehensive national water policy in the United States.
In response to Governor Arnold Schwarzenegger’s drought declaration and the recommendation of the 2002 Recycled Water Task Force, the California Department of Water Resources is in the process of adopting statewide standards to install both potable and recycled water plumbing systems within buildings.
This Dual Plumbing Code, once adopted, will be incorporated into the California Plumbing Code. The recycled water uses allowed in structures includes: floor trap priming, cooling towers, and air conditioning devices, as well as toilet and urinal flushing. The Code applies to structures including: commercial, retail, and office buildings, theaters, auditoriums, condominium projects, schools, hotels, apartments, barracks, dormitories, jails, prisons, and reformatories, and others as determined by the State Department of Public Health.

California regulators have opened the floodgates for using “gray water” by issuing an emergency decision that allows residents to create simple water-reuse systems without a construction permit.
The new California state rules provide permit exemptions for some residential graywater systems, but people still have to follow several requirements. They include:
- The system must allow users to direct water to an irrigation field or the sewer.
- Ponding and gray-water runoff are prohibited.
- Gray water can be released above ground, but the discharge point must be covered by at least 2 inches of mulch, rock or other material that minimizes human contact.
- Water used to wash diapers or other soiled garments must be sent to the sewer.
- Gray water shouldn't be used on root vegetables.

On July 8, 2009 the Universities Council on Water Resources (UCOWR) presented the Alliance for Water Efficiency with its 2009 Education and Outreach Award, given to recognize educational institutions, individuals, groups or agencies that have made significant contributions to increased public awareness of water resources development, use, or management covering any one or a combination of the natural, biological and social sciences. Mary Ann Dickinson, Executive Director of the Alliance, received the award at the UCOWR conference held July 7-9 in Chicago.
International toilet experts John Koeller and Bill Gauley have issued a cautionary statement about devices that convert standard toilets into dual-flush toilets. In the statement the authors note that these devices have not yet been independently tested for efficacy or water savings in the lab or the field. The authors urge caution in the “purchase, endorsement, or subsidy of these after-market devices”. Download the full text of the cautionary statement here.

- A recommendation to include a master irrigation shut-off valve.
The full text of comments are available on the AWE's WaterSense page.
EPA’s WaterSense and ENERGY STAR® programs are teaming up to develop a specification for high-efficiency pre-rinse spray valves. EPA wants to capitalize on the tremendous water and energy savings opportunity, improve and promote the use of more efficient pre-rinse spray valves, and help commercial and institutional kitchen, restaurant, and grocery managers make informed purchasing decisions to reduce their water and energy use, without sacrificing performance.
As a first step, EPA has issued a notification of intent (NOI) (PDF) to develop a specification for high-efficiency pre-rinse spray valves. This notice of intent (NOI) outlines EPA's approach to developing the draft specification, the efficiency and performance criteria EPA is working to define, and the technical issues that still need to be resolved related to these products.

By a 13-0 vote, the Los Angeles, California City Council has approved an ordinance that requires all new buildings to have high-efficiency faucets, toilets, urinals, shower heads and other plumbing devices.
Officials with the Department of Water and Power said the water conservation ordinance, which is part of the city’s Green Building program, would reduce water consumption in new buildings by 20%.
High-efficiency devices also will be required when property owners upgrade their plumbing fixtures, city officials said. As more fixtures are installed, “water conservation will become a way of life without people even having to think about it,” said DWP General Manager H. David Nahai.

As the West warms, a drier Colorado River system could see as much as a one-in-two chance of fully depleting all of its reservoir storage by mid-century assuming current management practices continue on course, according to a new University of Colorado at Boulder study. The study, published in the American Geophysical Union journal, Water Resources Research, looked at the effects of a range of reductions in Colorado River stream flow on future reservoir levels and the implications of different management strategies. Roughly 30 million people depend on the Colorado River -- which hosts more than a dozen dams along its 1,450 journey from Colorado's Rocky Mountains to the Gulf of California -- for drinking and irrigation water.

A new Pacific Institute report released July 22, Sustaining California Agriculture in an Uncertain Future, suggests that California agriculture can flourish despite diminishing water supply and future uncertainty from climate change -- but it will require great strides in increasing the water efficiency of the agricultural sector.
Many farmers and irrigation districts have already been making water-use efficiency improvements. Yet the analysis estimates that potential water savings of 4.5 - 6 million acre-feet each year can be achieved by expanding the use of efficient irrigation technologies and management practices.

Efficient2009, scheduled for Oct. 25-28, 2009 in Sydney Australia, brings together the community of researchers, practitioners, regulators and suppliers who, between them, work on achieving maximum efficiency of water use, across the world’s cities.
Australia has a legacy of a dry and variable climate, not to mention the added impacts of climate change. Efficiency practitioners here have valuable experiences to share, but are also keen to learn from colleagues around the world. The conference organizers expect a very cosmopolitan mix of delegates, many of whom are now part of the efficiency ‘family’, having a shared passion for this topic. The Alliance’s Executive Director, Mary Ann Dickinson, will be one of the keynoters in this conference.
If you can make it down under this October this should be an excellent and informative event. Download the detailed registration brochure here.

A new, three-dimensional water-modeling tool provides a detailed picture of how water flows below ground and how it relates to surface-water in rivers and canals in California’s Central Valley.
The Central Valley Hydrologic Model, developed by scientists at the U.S. Geological Survey, is available for use by water managers and other agencies. The model was designed to help resource agencies assess, understand and address the many issues affecting the joint use of surface- and groundwater supplies – known as “conjunctive use” – in the Central Valley.
“This new model not only details the current scarcity of groundwater, but also provides a scientific tool to help water managers remedy the situation in the future,” said Secretary of the Interior Ken Salazar. “Science can be invaluable in helping to provide solutions.” Download the full report here.
A new document from the Aspen Institute summarizes a dialogue by national experts on drinking water infrastructure and outlines 10 major points of agreement by this group. The Aspen Institute wrote the text of the report, pulling language and insights from the discussion during four meetings over the course of a year.
The report, while taking a hard and new look at the definition of water infrastructure, does solve all the issues of sustainable infrastructure funding or gaps thereto. Most notably, the group did not reach consensus on issues regarding which funding mechanisms are appropriate to finance a modern view of water infrastructure, including the utility of a federal trust fund.

Britons could save 30% of the carbon emissions associated with heating water at home by following simple advice such as insulating pipes and using low-flow taps, according to energy experts.
They estimate that installing just a few water-saving measures could save a typical household £225 (~$400) per year on combined water and energy bills.
In a joint report, the Energy Saving Trust and the Environment Agency examined the carbon impact of domestic water use in the UK. They concluded that heating water would continue to be a major source of carbon emissions from homes in the future unless urgent action was taken to reduce demand and the associated energy losses from inefficient boilers.
Looking for energy (and water) savings ideas to share with your members or customers?
Energy STAR reminds us that clothes washers manufactured before 1999 use more than 4 times the energy of today's efficient models and are wasting nearly 30 gallons of water every time someone does a load of laundry. Over the lifetime of the washer, consumers could be wasting water equivalent to ten and a half years of daily baths! The U.S. Department of Energy has announced the Energy STAR Make a Clean Change: Recycle Your Old Washer Campaign. Found at www.energystar.gov/recycle, this campaign encourages consumers to properly recycle their old washers and, if needed, replace them with new Energy STAR qualified models.
Israel has implemented new tax on excessive household water consumption. This policy took effect in July and is expected to save about 15,850 million gallons of water a year (43.4 MGD). A family of four is allowed 8,453 gallons every two months (4.2 kgal per month) and larger families receive an additional 1,110 gallons per person per month. Households that exceed their allotment are likely to pay hundreds of extra shekels as part of the excess use tax.
Water experts Ofer Alon and Shimon Tzuk, along with the Israel Water Authority, advised the public to save water painlessly by changing their habits (taking shorter showers and using a dishwasher instead of doing dishes by hand, for example) and installing inexpensive equipment to reduce water pressure in kitchens and bathrooms. A dual-flush toilet tank was also recommended.
The World Bank approved a loan of $1.25 billion US to build a canal linking the Red Sea to the Dead Sea, a move that will give new life to a much-discussed but much-delayed project. Israeli Development Minister Sylvan Shalom made the announcement after a meeting with World Bank President Robert Zoellick in Washington, DC.
The Dead Sea, which has been steadily drying out, is in urgent need of replenishment, and the pilot stage of the proposal will run a channel from the Red Sea to recharge it. Half of the seawater will feed a giant desalination plant, to be operated jointly by Israel, Jordan, and the Palestinian Authority. In the second stage, a bigger canal would supply 2 billion cubic meters of water a year to maintain and increase water levels in the Dead Sea. Read more here.

There's water out there...somewhere. Need more water? Space is the place! Researchers at the Southwest Research Institute in San Antonio, Texas, found new evidence of liquid water on Enceladus, a frozen moon of the planet Saturn. Investigator William Lewis said that ammonia, the isotope deuterium, and various organic components had been detected in a geyser spouting from the moon's South Pole. Ammonia acts as an antifreeze, so even though the surface temperature is around 100 degrees C below zero, it's possible that significant amounts of water lie below the surface, Lewis explained.
