WALNUT CREEK, Calif. — The Water Environment Research Foundation (WERF) presented Seattle Public Utilities (SPU) and Brown and Caldwell with the Award for Excellence in Innovation at this year's Water Environment Federation Technical Exhibition and Conference (WEFTEC), according to a press release.
The team has worked to improve the flood grouting process, the release reported, which allows SPU to deal with frequent sanitary sewer backups and overflows in certain city neighborhoods.
"This has been a very successful project, through both the application of a new technology to reduce backups and the use of asset management to assess the project's costs and benefits," said Bob Jacobsen, senior engineer with Brown and Caldwell.
Sewage volumes have decreased by 66 percent and peak flow rates by 41 percent through this project, the release noted.
According to the release, Brown and Caldwell was also recognized with a WERF award for innovation in 2011.
