Existing stormwater systems require significant investments to meet challenges imposed by climate change, rapid urbanization, and evolving regulations. There is an unprecedented opportunity to improve urban water quality by equipping stormwater systems with low-cost sensors and controllers. This will transform their operation from static to adaptive, permitting them to be instantly "redesigned" to respond to individual storms and evolving land uses. © 2016 American Chemical Society.

A business's name is its most valuable marketing tool, especially for public utilities that have limited marketing budgets. An organization's name should communicate what it does and what it cares about. After studying research and having conversations with key influencers and customers, the Unified Sewerage Agency became Clean Water Services in 2001. The name is more closely aligned with customer values and expectations, suggests a broader set of competencies, is more easily understood, and is focused on the future. Clean Water Services and DHM Research continue to work together to monitor changes in public opinion and to learn new information to inform communications development and stakeholder engagement in the agency's planning and decision-making. Through focus groups and surveys, Clean Water Services has learned more about values the public associates with water. Clean Water Services has used community engagement and strategic partnerships to position itself as a valuable member of the community that ?blends science and innovation with the power of Mother Nature to safeguard the river's health and vitality, ensure the economic success of the region, and protect public health.

Over the last five years, Clean Water Services developed and implemented a program to offset thermal load discharged from its wastewater facilities to the Tualatin River by planting trees to shade streams and augmenting summertime instream flows. The program has overcome challenges facing many of the nation's water quality trading programs to not only gain consensus on the frameworks needed to authorize trading, but also provide a broad range of ecosystem services. This paper compares the Tualatin case study with some of the commonly cited factors of successful trading programs. © 2010 American Water Resources Association.

Low Impact Development 2010: Redefining Water in the City - Proceedings of the 2010 International Low Impact Development Conference | Year: 2010
For nearly 40 years, Oregon has enacted land use laws to control urban sprawl and protect agricultural land. Washington County envisioned the recent 800 acre expanded urban growth boundary in North Bethany as a "Community of Distinction" and wanted to raise the bar for community planning in Oregon. Among the goals adopted by project stakeholders was one stating a variety of parks, protected open spaces, and water quality facilities will result in a designed and coordinated system integrated within the urban fabric. As the project stakeholder responsible for stormwater management and in the North Bethany Study area, Clean Water Services saw a unique opportunity to come up with a drainage master plan for a large, undeveloped area that considered what works and improve upon what is not working. The resulting strategy takes a comprehensive approach to incorporating stormwater management into the landscape of North Bethany by protecting natural resource areas, utilizing Low Impact Development (LID), and discouraging small, isolated facilities hidden in fenced corners. Clean Water Services will continue to require riparian buffers on all jurisdictional waters. Regional facilities will be located adjacent to natural resource areas, outside of regulatory buffers, and integrated with the park system as a linear feature with the trail system, or as a multi-purpose facility within a community park. Washington County and Clean Water Services have already begun to address the challenges associated with implementing LID, including revisions to design and construction standards, maintenance agreements, modifications to street standards, creation of a LID Handbook, and public education. Coordination will be on-going. © 2010 ASCE.

The first full-scale nutrient recovery installation in North America became operational in May 2009 at the Clean Water Service's Durham Advanced Wastewater Treatment Plant in Tigard, Oregon. Recovering ammonia and phosphorus from the dewatering side stream as struvite has a positive impact on plant operations. Significantly reducing the phosphorus recycle lowers the phosphorus loading on the plant, stabilizes biological phosphorus removal, reduces the amount of chemicals needed to remove phosphorus, reduces both the dry tonnes of biosolids generated and the phosphorus content of the biosolids, and provides revenue from the sale of the struvite. To increase struvite production and to decrease struvite potential in the digestion system, the Waste Activated Sludge Stripping To Remove Internal Phosphorus (WASSTRIP™) process was implemented full-scale in summer 2011. Results indicate a potential 60% increase in struvite production is achievable. © IWA Publishing 2013.

Several agencies and companies in the US continued to make significant efforts to to deal with the challenge of declining quantities of phosphorus in wastewater treatment processes. Clean Water Services (CWS), a water resource management utility from Oregon, established the first commercial facility in the country in June 2009. It incorporated Pearl® nutrient recovery process technology from Ostara, Vancouver, B.C., Canada, to address this issue. The company used this new technology at its Durham Advanced Wastewater Treatment Facility (DAWTF) to help meet tight phosphorus discharge regulations. The Pearl nutrient recovery process was based on a proprietary fluidized bed reactor in which magnesium was bed reactor in which magnesium liquor to precipitate struvite under a controlled chemical reaction. The joint effort of between these companies was also able to generate 300 tons of struvite, representing 76,000 pounds of phosphorus and 34,000 pounds of ammonia recovered from the system.
