House and Senate panels are meeting in December to examine the critical needs of the nation's aging and outdated drinking water and sewer treatment systems and pipelines, which EPA estimates need more than $635 billion in improvements.
The Senate Environment and Public Works subcommittee on water, which is chaired by Maryland Democrat Ben Cardin, held a hearing on the "challenges and opportunities" for the nation's water infrastructure. While the House Transportation and Infrastructure's Water Resources and Environment Subcommittee, chaired by Rep. Bob Gibbs (R-Ohio), plans to focus on EPA's effort to give cities greater "flexibility" in meeting the often multibillion-dollar burdens of bringing outdated sewer systems into compliance with the Clean Water Act.
Experts are sounding alarms that the nation's water infrastructure is in terrible shape. The U.S. Geological Survey estimated that leaky pipes lose 1.7 trillion billion gallons of treated water each year. The American Society of Civil Engineers in 2009 graded U.S. water a D-minus.
In recent years, EPA and the Department of Justice have cracked down on more than 30 cities who have outgrown their sewer systems, forcing them into binding legal agreements to make what often amount to multibillion-dollar repairs and upgrades under specified timelines. As a result, sewer rates are rising fast across much of the United States.
The Colorado River basin presents the greatest water management challenges of any river basin in the nation, with ever-expanding demands for multiple water uses, water demand exceeding supply, valued but fragile ecosystems, and support for nearly every type of water-relevant interest. The importance of instream flows – the amount of water flowing in a stream or river – is more pressing than ever, but in many parts of the basin, all water is spoken for.
Alliance for Water Efficiency
, American Rivers and the Environmental Law Institute partnered on a project funded by The Walton Family Foundation to outline the practical possibilities for linking water efficiency efforts and healthier instream flows in the Colorado River basin. If a stretch of water is identified as needing improved instream flow, and a realistic opportunity for improving water efficiency exists, willing partners generally can build the bridges necessary to overcome other challenges. That is the principal finding of the report completed and released on November 14, 2011 by the three organizations.
“We see an opportunity here for communities to do double duty with water efficiency: meet their water needs and benefit the environment at the same time,” said Mary Ann Dickinson of the Alliance for Water Efficiency. “We wanted in this project to document what the barriers and issues might be in moving this concept forward.” Learn more and download a free copy of this report here.
Gov. Jerry Brown recently vetoed AB 275, the proposed Rainwater Capture Act of 2011.
AB 275 would have authorized a landowner to install and operate a rainwater capture system for (1) outdoor nonpotable use or infiltration into groundwater or (2) subsequent indoor nonpotable use.
In his veto message, Gov. Brown stated his preference for adopting a rainwater capture standard through the state’s Building Standards Commission process.
The International Code Council (ICC), which opposed AB 275, had earlier pointed out that California law requires that building codes be adopted by the commission. ICC also noted that the 2010 Green Plumbing and Mechanical Code Supplement, which AB 275 referenced, is not a code, nor had the commission adopted it.
This is the second year in a row that a California governor has vetoed a rainwater capture bill. Governor Arnold Schwarzenegger vetoed a similar bill last year for different reasons. Learn more here.
Texas voters have approved a proposition to promote water conservation. Proposition 2 will let the state create a revolving $6 billion bond package to finance water conservation and sewage and flood control projects.
Supporters, including The Nature Conservancy and some in the energy industry, said more bonding authority for the Texas Water Development Board is needed to update water utilities and to pay for the state water plan.
"The availability of water is an issue that cuts across every district and impacts every citizen," Texas House Speaker Joe Straus said.
But critics argued that Proposition 2, along with the other bonding plans -- Propositions 3, 4 and 7 -- would increase government spending by granting permanent permission for various entities to issue more bond debt. Voters rejected Proposition 8 that would have given tax breaks to landowners who take measures to conserve water and preserve water quality.
Meanwhile, state officials prepared for continued severe drought conditions across Texas. Read more about the recent Texas election here.
The U.S. Environmental Protection Agency’s (EPA) WaterSense program has released a final specification for irrigation controllers, making them the first outdoor product category eligible to earn the WaterSense label. Manufacturers of these products may become a WaterSense partner and begin the certification process to earn the WaterSense label. EPA expects that WaterSense labeled controllers could be available by the spring of next year.
Weather-based irrigation controllers (WBIC) use local weather data to tailor irrigation schedules to actual site conditions. WaterSense labeled models will be independently certified to meet EPA’s water-efficiency and performance criteria, ensuring that they are able to meet the water needs of the plants without overwatering.
The performance record of WBICs is somewhat mixed. Some models have performed well in laboratory-like test settings. The largest field study of WBICs to date, conducted in California (Aquacraft, 1999), found they reduced irrigation application rates by an average of 6%.
For more information about the WaterSense Specification for Weather-Based Irrigation Controllers, visit the WaterSense website, or contact the WaterSense helpline at (866) WTR-SENS.

An energy efficient home could mean a better mortgage for the borrower. The Sensible Accounting to Value Energy Act of 2011 (S.1737), introduced on October 19 by Senator Michael Bennet, Democrat of Colorado and Senator Johnny Isakson, Republican of Georgia would require that home energy costs be factored into the formula for determining a home’s overall value and the prospective homebuyer’s eligibility for a loan.
The preferred tool for estimating energy costs is Residential Energy Service Network’s Home Energy Rating System, although the law would allow other suitable third-party methods to be used . Learn more here. If this bill is a success, perhaps water efficiency could be considered in the future.
An important study on the potential for building drainline blockages with water efficiency plumbing fixtures is just short of funding it needs to move forward. Researchers are seeking an additional $50,000 needed to move this project forward.
Water-efficient fixtures lead to reduced water consumption, and can result in lower drainline and sewer line water flows. This provokes important questions: Do these reduced flows lead, in turn, to stoppages of waste in building drains? How low can flows can be reduced without causing solids to clog the drainline? Does the installation of certain high-efficiency plumbing fixtures contribute to stoppages? If so, are remedies available that can mitigate or prevent drainline stoppages?
Work on this important research can begin in January 2012 thanks to generous contributions from water utilities and others and a kind offer from American Standard Brands to allow the use of its test apparatus. However, an additional $50,000.00 in funding is necessary to get this important research started.
If you wish to support this research, please contact Mary Ann Dickinson at the Alliance for Water Efficiency as soon as possible. Contributions are tax deductible. Learn more about the proposed research here.

The International Code Council has finalized its International Green Construction Code and is readying it for publication by Spring of 2012. The code includes many water and energy saving features that will be familiar with anyone who has followed other green codes, standards and programs. It also has provisions intended to make the code simple to follow without performing calculations.
Thomas Pape, representing the Alliance for Water Efficiency, got one alteration on the table for remote water closets that may be on the end of a drain line in a commercial building. Those can be 1.6-GPF water closets if they are, “… located not less than 30-ft. upstream of other drain line connections or fixtures and … located where less than 1.5 drainage fixture units are upstream of the drain line connection.”

The production of electricity, from fuel extraction to generation, has growing impacts on both water availability and quality. A new analysis from the Pacific Institute evaluates future water needs for different energy futures and identifies a growing risk of conflicts between electricity production and water availability in the U.S. Intermountain West. The new report also identifies strategies to ensure the long-term sustainable use of both resources.
Water for Energy: Future Water Needs for Electricity in the Intermountain West, examines the water requirements for current and projected electricity generation within the Intermountain West, which is the area bound by the Rocky Mountains in the East and the Sierra Nevada and Cascade Mountains in the West. While water and energy conflicts are increasing across the United States, the Intermountain West is of particular interest for this study because it has a growing population (and growing demand for energy and water), a diverse fuel mix for power generation, and existing water constraints and limitations that are expected to worsen.
Australia experienced a serious drought over the last decade and as a consequence most municipalities had to introduce policies to reduce the water usage in their urban areas. The demand-management tools employed included, raising water prices, mandatory restrictions on certain types of water use, and approaches aimed at inducing a voluntary behavior change.
Researchers tested the effectiveness of the various policy tools empirically using daily water use data for a single municipality over the period of 4 ½ years. They observed large and significant effects from increasing restrictions on water use, and also economically and statistically significant effects which can be attributed to information campaigns and ‘altruistic' behavior. Perhaps surprisingly, they were unable to identify a significant price effect once they controlled for the level of use restrictions.
The authors concluded that at times of extreme water shortage, formal restrictions and encouragement of voluntary consumption reductions are at least as effective as price instruments. Download a free report summary here.
In response to criticism of the Las Vegas Valley’s ongoing water conservation efforts, an attorney for the Southern Nevada Water Authority (SNWA) questioned a report by the Pacific Institute that criticized Southern Nevada’s efforts to reduce water use - initiatives that SNWA says have already have yielded a 30 percent reduction in per capita water use.
Following direct testimony by Pacific Institute President Peter Gleick, in which he claimed Southern Nevada’s conservation efforts were “weak and inadequate,” SNWA attorney Steve Sims identified numerous areas in which the institute’s report, “Hidden Oasis: Water Conservation and Efficiency in Las Vegas” grossly overstated additional potential water resources that may be gleaned through additional conservation.
The report was prepared by the advocacy organization at the request of an activist group opposing the SNWA’s applications for renewable, unused groundwater in east-central Nevada. Read more about SNWA’s critique here.

UK Water Industry Research (UKWIR) has published the 2011 edition of Managing Leakage. The original Managing Leakage was published in 1994. It fast became the definitive reference document for water loss control , not just in the UK but throughout the world, with the methodologies recommended in the document identified as best practice. Since then, research and practice in water loss management has continued to develop with over thirty reports published by UKWIR alone on the subject and related topics. Although much of the original document is still relevant, more recent research has added to the knowledge in some areas, such as leakage economics, pressure management, asset management and leakage location technology. Managing Leakage 2011 includes those parts of the original document which are still relevant but also more recent studies and developments with over 100 documents referred to and listed. Managing Leakage 2011 is available for sale from UKWIR.
