Alexandria, VA (PRWEB) October 09, 2013
The Water Environment Research Foundation (WERF) recognized Seattle Public Utilities (SPU) with its Award for Excellence in Innovation on Tuesday afternoon for a research project that dramatically reduced wet weather flows in the city’s Broadview neighborhood. SPU received the award for its use of an innovative evaluation process that identified a new technology to reach successful rehabilitation outcomes in Broadview.
The WERF Award for Excellence in Innovation recognizes organizations that have made improvements to wastewater and stormwater collection, storage or treatment operations, facilities, or processes by applying WERF research. SPU is one of four organizations to receive the award this year.
The Broadview neighborhood of Seattle has experienced frequent wet weather sanitary sewer backups into private property and sanitary sewer overflows (SSOs) into the public rights-of-way. Through the evaluation process to identify the best technology for this project, and working with consultants from Brown & Caldwell, SPU determined that using the Sanipor flood grouting technology in the sewer system had the greatest benefit/cost ratio. Flood grouting is aimed at stopping infiltration into sewers by simultaneously sealing large portions of a system, including maintenance holes, sewer mains, and laterals.
A critical achievement of this project was demonstrating the ability to work on privately owned assets for the greater good of the community – SPU gained 95% participation to enter private property. But the greatest result was the effective reduction in wet weather flows. This reduction in wet weather flows saved SPU money due to reduced claims related to flooded basements and regulator fines for sewer overflows.
A team of WERF volunteers, who themselves are some of the most recognized individuals in the water quality industry, selected the recipients from a field of many well-qualified organizations. Additional information on this award can be found at http://www.werf.org.
The Water Environment Research Foundation, a nonprofit organization formed in 1989, is America's leading independent scientific research organization dedicated to wastewater and stormwater issues.
In addition to providing a reliable water supply to more than 1.3 million customers in the Seattle metropolitan area, SPU provides essential sewer, drainage, solid waste and engineering services that safeguard public health, maintain the City’s infrastructure and protect, conserve and enhance the region's environmental resources.
