Sewer project receives USACE award
Affholder Inc., Chesterfield, Mo., has received an award for outstanding contract performance from the U.S. Army Corps of Engineers (USACE), St. Louis District. The award salutes the company's work on a sewer rehabilitation project for the Metropolitan Sewer District (MSD) of St. Louis. The Corps made federal funding available to MSD to cover approximately 75% of the $4 million project. The project included rehabilitation of 3168 feet of pipe extending along Vandeventer Avenue to Grand Avenue in south St. Louis. It encompasses grouting, installation of a concrete invert, and application of shotcrete to the existing sewer to fill voids and repair connections.APA launches quiet pavement site
The Asphalt Pavement Alliance (APA) has launched www.quietpavement.com, a Web site designed to inform public works professionals and the general public about the impact of road noise and methods for reducing road noise using hot-mix asphalt. The site includes several interactive features, such as a section in which visitors can build their own virtual roads and estimate noise levels.Stormwater Web site launched
StormwaterAuthority.org is designed to help private and public sectors in making informed decisions about stormwater treatment and management. It includes news, articles, stories, and leading technology updates from industry leaders. In addition, it provides access to a variety of tools and expert guidance, including an exhaustive guide of stormwater-related regulations by state. The site is supported by a number of organizations and companies, including Vortechnics, Water & Wastes Digest, and Environmental News Service.Judge sides with water board for cleanup plan
A Los Angeles Superior Court judge rejected an effort by a coalition of cities and developers to prevent a countywide stormwater cleanup plan that would reduce the largest source of pollution to California's coast. The judge ruled in favor of the Regional Water Quality Control Board and three conservation groups that intervened in the lawsuit. The cleanup plan employs new measures such as detailed inspections of industrial facilities and the use of drain filters and silt-removal basins to cut the amount of stormwater runoff to the state's coastline.Entries sought for smart-growth awards

A survey conducted by the Portland Cement Association (PCA) in 2004 measured attitudes about the use of soil-cement and roller-compacted concrete (RCC) for water resources rehabilitation. Among the key findings published in the report—entitled Measurement Criteria: The 2004 Water Resources Market—are:Inadequate spillway capacity and seepage are the most common problems.Solutions considered for inadequate spillway capacity are to enlarge existing spillways, build new spillways, or provide overtopping protection.The use of RCC for overtopping protection, new dam construction, and replacement will increase over the next five years.The Army Corps of Engineers, PCA, and the Bureau of Reclamation are the leading sources of design information.
