This year the cured-in-place pipe rehabilitation process and Insituform Technologies, the company that created it, celebrate a significant milestone: Insituform’s 40th birthday and the anniversary of the completion of the first commercial CIPP project, a 12-inch sewer.
The U.S. Army Corps of Engineers, St. Louis District, MO, has awarded a $9.178 million contract to SAK Construction for the Old Mill Creek Phase 1A project for the Metropolitan St. Louis Sewer District. The project, which targets the aging Old Mill Creek Sewer and smaller connecting sewers, is designed to eliminate or control related sewer overflows that affect both the city of St. Louis and St. Louis County, MO.
Sewer lines will soon be getting a major overhaul in the city of Fort Worth, TX. The city council approved a $446,192 engineering contract with White Rock Consultants to begin work on the new improvement project. Fort Worth is paying for the project using money already budgeted in the Water and Sewer Fund.
In many American cities, the sanitary sewer laterals that connect homes and commercial structures to sewer main lines have been allowed to deteriorate and become a significant source of sewer system inflow and infiltration (I&I), along with other problems.
URETEK's Zero Excavation inflow and infiltration solution is a quick, efficient, low-impact, repair solution that deploys an expanding, hydro-insensitive, high-density polyurethane foam to seal, encapsulate, and stabilize infrastructure systems.
The Waterfront Mall Project under construction in Washington, DC, will contain retail stores, restaurants, offices and residential units. Through the middle of the site there is an existing 100-year-old, 90-inch diameter storm sewer about 800 feet long. In what should have been a relatively simple project to rehabilitate the pipe, with a few significant yet manageable challenges, circumstances quickly changed to create the “job from hell.”
Utility districts understand that water and sewer pipes deteriorate over time. This is especially true for concrete pipes installed in sanitary sewer systems. An inherent issue with sewage is the build-up of hydrogen sulfide (H2S) gas, which can have far-reaching effects that may not be noticeable until a major problem occurs.
