16 Industry News water June 2015 WATER REUSE ADVOCATE WINS 2015 STOCKHOLM INDUSTRY WATER AWARD CH2M has been named 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 recognised that our global community cannot afford to use water once and dispose of it – freshwater 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’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 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 for the country’s NEWater project. By combining state-of-the-art technology and public education tools, unprecedented public acceptance of water reuse was achieved. 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 the International Water Association (IWA) and the World Wide Fund for Nature (WWF). NO-DIG DOWN UNDER AT THE GOLD COAST In September 2015, the Gold Coast Convention and Exhibition Centre will play host to the largest trenchless event in Australasia, No-Dig Down Under. The event will provide over 1,000 delegates with insights into innovative and new techniques for installing and renovating underground infrastructure. The technical program includes speakers from around the globe who will be presenting papers covering case studies, new and emerging technologies, challenging projects and environments, risk management and more. Delegates will enhance their skill-set by learning about the role trenchless technology plays in reducing carbon emissions, reducing occupational health and safety risks, and protecting the environment and existing infrastructure, among many other benefits. Delegates will also have the opportunity to hear from a diverse range of local and international speakers, covering topics in lining solutions, microtunnelling, pipe jacking, directional drilling, stormwater and a vast array of case studies. Delegates will also be offered an extensive range of social and networking opportunities, including the Exhibition Opening, Boat Cruise to South Stradbroke Island and Gala Dinner and Awards Evening. This will be the trenchless industry’s main event for the year, and the evening will include presentation of the 2015 ASTT awards, which recognise outstanding people and projects in the industry.

Split into two parts, the project aims to understand the current and anticipated future performance of the sewerage systems under the influences of urban growth and wet weather. The first stage will involve monitoring flows within the systems during dry and wet weather events over the course of 12 weeks through the installation of 46 flow monitors and 12 rain gauges. These results will then be used to model growth-related dry-weather flows and wet-weather flows across a range of average recurrence intervals. Mott MacDonald will analyse flow data to identify any likely issues with inflow, infiltration or other hydraulic issues. The consultancy will also build, calibrate and masterplan the entire flow modelling stage. Peter Stephens, Mott MacDonald1s project director, said: “The models will be used to develop options that will accommodate future growth and reasonable wet weather flows in the sewerage systems. The projects identified will be put forward for design and construction, mainly over the next five-year planning period from 2017-22 .” The project is expected to be completed in the middle of 2016. In the 1970s, CH2M worked with the upper Occoquan Service Authority’s regional water reclamation plant in Virginia, uS, to design the world’s first and largest indirect potable reuse plant.
