CH2M wins Stockholm Industry Water Award

Passionate advocate for water reuse wins 2015 Stockholm Industry Water Award

Stockholm (09 June 2015) – CH2M, a Colorado-based global service and engineering company, has been named the winner of the 2015 Stockholm Industry Water Award, for developing and advancing methods to clean water, and increasing public acceptance of recycled water.

“CH2M has long recognized that our global community cannot afford to use water once and dispose of it—fresh water sources are too precious and growing more scarce. We are proud to receive the 2015 Stockholm Industry Award for our leadership in the evolution and acceptance of purifying wastewater effluent to create drinking water,” said Greg McIntyre, CH2M Global Water Business Group President.
CH2M has invented, implemented and refined methods for cleaning used water back to drinking water quality. But, since this water is only valuable if people actually use it, the firm has put significant and successful effort into building public understanding and acceptance. They pioneered the application of social science research to better understand the underlying reasons for why people reject the notion of reuse and what might be done to change that mindset. This research, combined with demonstrations, education and transparency has dispelled myths around use of treated wastewater and paved the way for a surge in interest in and acceptance of potable reuse.
“Our planet does not hold any enormous, unknown sources of fresh water. We have to live with what we have. With growing populations and more unreliable precipitation patterns, it is essential to increase our reuse of water in the future,” says SIWI’s Executive Director Torgny Holmgren, and adds: “CH2M has understood this. In working for public acceptance of drinking treated wastewater, they have taken a step beyond engineering, and shown impressive commitment to wise water management.”
“Through rigorous testing and analysis of both technical processes and societal perceptions, CH2M has created the opportunity to close the urban water loop,” states the Award Committee in their citation.
CH2M’s first notable success in wastewater recycling came in the 1960s, when CH2M pioneered the third, advanced stage of effluent treatment by successfully removing excess phosphorous, nitrogen and trace metals, restoring the used water of the South Tahoe Public Utility to pristine purity. Through a series of improvements, tests and large-scale implementation, the technology of treating used water back to drinking water quality was further refined to increase reliability, efficiency, and sustainability.
In the 1970s, CH2M designed the world’s first surface water indirect potable reuse plant, improving the water quality for more than one million people in northern Virginia—raising the bar for cost-effective wastewater treatment.
“CH2M was founded out of a deep belief that engineering technology could make the world a better place. While technological innovation is an important part of our contribution to water reuse, many of the pivotal water reuse milestones would not have been built if the public had not accepted them. Through technology and innovative public education tools, we will continue to contribute to a more sustainable water future,” said Brock McEwen, CH2M’s Global Water Technology Director.
CH2M continued to evolve water reuse practices and in the early 2000s worked with Singapore’s national water agency, to not only prove the safety of potable reuse, but to win public acceptance with the country’s NEWater project. By combining state-of-the-art technology and public education tools, unprecedented public acceptance of water reuse was achieved.
“In a rapidly urbanizing world where the vast majority of sewage spills untreated out into the environment, the transformative technologies and strategic communication of this year’s SIWA winner has provided a significant step towards future water security of cities.” the Award Committee concludes.

SIWA – recognizing water excellence in the business world
The Stockholm Industry Water Award (SIWA) was established in 2000 to stimulate and celebrate outstanding and transformative water achievements by companies in improving production, managing risks, finding solutions and contributing to wise water management. The Royal Swedish Academy of Engineering Sciences (IVA) and the World Business Council for Sustainable Development (WBCSD) were partners in establishing the award, which is also supported by International Water Association (IWA) and World Wide Fund for Nature (WWF).

Container-based sanitation: Assessing costs and effectiveness of excreta management in Cap Haitien, Haiti

    Abstract

    Container-based sanitation (CBS) – in which wastes are captured in sealable containers that are then transported to treatment facilities – is an alternative sanitation option in urban areas where on-site sanitation and sewerage are infeasible. This paper presents the results of a pilot household CBS service in Cap Haitien, Haiti. We quantify the excreta generated weekly in a dense urban slum,(1) the proportion safely removed via container-based public and household toilets, and the costs associated with these systems. The CBS service yielded an approximately 3.5-fold decrease in the unmanaged share of faeces produced, and nearly eliminated the reported use of open defecation and “flying toilets” among service recipients. The costs of this pilot small-scale service were higher than those of large-scale waterborne sewerage, but economies of scale have the potential to reduce CBS costs over time. The paper concludes with a discussion of planning and policy implications of incorporating CBS into the menu of sanitation options for rapidly growing cities.

Want to pass the Water for the World Act?


The Water for the World Act has now passed both the House Foreign Affairs Committee and the Senate Foreign Relations Committee.
 
The next step in both the Senate and the House is to bring it up for a full floor vote, then send it to President Obama's desk for signature.
 
There are a very few days remaining in this session of the U.S. Congress, however. Some sector specialists fear that the bill will die if it doesn’t pass both the House and the Senate in the next few working days.

If you want to help advocate for the passage of the Water for the World Act, you can:
1) Contact your Representative and each of your Senators. Ask them to support the bill, and to bring it to the floor of the House/Senate for a vote. You can find contact information for your representative and senators here: https://www.congress.gov/members
2) Forward this message to others 

A copy of the Senate version of the Act can be found here: 
 
Talking points about the Act that were prepared by the NGO Water Advocates can be found here:

Congratulations to the re.source, winners of a 2014 US Environmental Protection Agency P3 award!

In many of the world’s overcrowded urban slums, residents must choose between open defecation, crowded public toilets or expensive private pit latrines that can't be emptied safely. A Stanford team working on a sustainable solution recently won a $15,000 grant from the U.S. Environmental Protection Agency (EPA) and the opportunity to compete for up to $75,000. See the full story here.

Congratulations to the Lotus Water team, winners of the 2014 Reed Elsevier WASH Alliance Prize!

The WASH Alliance prize of $15,000 was awarded to the Stanford Program on Water, Health and Development. Researchers have designed a community-scale, fully automated chlorine dosing device for shared water points in low-income urban settings that requires neither reliable electricity nor 24/7 supply to function consistently. Support from the Reed Elsevier Environmental Challenge will allow them to be able to construct, install and maintain 150 devices serving 10,000 people in Dhaka, Bangladesh. These installation sites will be used to evaluate health impacts and test the viability of different potential business models.

See the Lotus Water website for more information about this ambitious project!
