Pipe bursting specialist No-DigTec of Dallas upsized a 43-year-old, 24-in., reinforced concrete (RC) sewer pipe for The Trinity River Authority of Texas (TRA) with the pipe bursting technique.The job was part of a larger Arlington and Fort Worth, Texas, wastewater sewer upgrade project undertaken by general contractor, Mountain Cascade.
The Gulf Coast Water Authority (GCWA) and the City of League City, Texas, were faced with the need to rehabilitate 6,800 ft of a 39-in. PCCP water transmission main along a relatively narrow section of roadway.The decision to complete the rehabilitation of this main — which provides an interconnect between the City of Houston and Galveston County — using Swagelining allowed planners to keep the same hydraulic model/capacity, as well as giving the pipe a full structural overhaul that extended the life expectancy to at least 100 years.

Shawinigan is a small town in the Mauricie region of the province of Quebec, Canada. Like most small North American towns, the town was established near a river in the early 1900s, in this case, for its abundant wood that traveled down the rapids to Trois-Rivières, a renowned pulp and paper hub in the province.
A Different Twist on Pneumatic Assist Pulls a California Contractor Through a Tough Pipebursting Job
In the East Bay, Phase 5 of the Central Contra Costa Sanitary District’s sewer rehabilitation program for summer 2014 targets thousands of feet of public sewer mains located primarily in the dry oak-dotted hills of Orinda, Calif. The project calls for replacement of 6-, 8-, and 12-in. mains by either open-cut or pipebursting methods. Some pipelines will be upsized and most run through hillside easements between large well-kept properties in this relatively exclusive area.
In order to guarantee the supply of high-quality drinking water to residents, AWWA estimates that investments of $526 billion are required for the replacement or renovation of deteriorated water mains in the next 25 years. The latest EPA report on U.S. water infrastructure comes to the conclusion that investments of $248 billion are required over the next 20 years. President Obama just recently signed the Water Resources Reform and Development Act (WRRDA) into law to modernize the U.S. water infrastructure.
In spring and fall of 2013, multiple segments of an existing 15-in. RCP gravity sanitary sewer in the City of Montpelier, Vt., collapsed along a main commuter route in the downtown area causing a system failure. Numerous excavated point repairs were required to get the failed pipe flowing again.
Levees form a critical part of the United States infrastructure, as past flooding has demonstrated. When a levee is breached, it causes both personal and financial hardship. With 43 percent of residents living in a county with at least one levee, their upkeep is essential.
Spray-Applied Structural Lining Proves Its True Worth and Properties as Part of an Unusual Manhole Rehabilitation Demonstration
Mishawaka occupies one of the busiest intersections in “America’s Crossroads,” making it an ideal location for transporting people and goods across the nation and home to a diverse population of more than 50,000.
Like many sewer districts, South Whitehall Township, in Lehigh County, Pa., is under an administrative order from the U.S. Environmental Protection Agency (U.S. EPA), along with 14 other Pennsylvania municipalities that all transfer wastewater to a common treatment plant in Allentown.
The unsung hero in CIPP projects is the stuff that makes it stick to the wall of the pipe — the resins.Since 1959, Interplastic Corp. has been manufacturing unsaturated polyester, vinyl ester and specialty resins, gel coats, colorants and putties under the CoREZYN, Silmar and Integrity brand names for the composites and cast polymer industries.
To gauge the pulse of the industry, Trenchless Technology annually hosts a gathering of industry leaders to discuss the trends and issues facing the trenchless market, as well as the future outlook. To help focus the discussion, we approach it from a certain angle or viewpoint.
Over years of use, sewer lines suffer damage that can include holes, cracks and erosion. To ensure the continued function and safety of aging collection systems, owners must routinely undertake extensive pipe repairs and rehabilitation. Various technologies are used for this purpose.
Charleston Water System (CWS) is no stranger to using trenchless technology to address its underground infrastructure needs. Recently, CWS employed it once again to structurally rehabilitate 15,600 lf of reinforced concrete and ductile iron sewer and more than 20 manholes.
The success of a recent water main replacement in Moorhead, Minn., backed by positive readings from a digital pressure and pullback monitor, helped change some minds about restrained-joint PVC pipe’s resilience in static pipe bursting applications.
Culverts and storm sewers have been a part of our infrastructure even before the advent of the federal highway system in the 1940s and 1950s, when the demand and the necessity for drainage pipes sprang from the growth in the number of automobiles traveling the roadways.
The Consolidated Mutual Water Co. (Consolidated) serves approximately 90,000 residents in Lakewood, Wheat Ridge and unincorporated portions of central Jefferson County in the ‘Metro’ area around Denver, Colo.
TT Technologies has literally grown up with the trenchless technology industry, coming into being before the term “trenchless” became synonymous with the rehabilitation of underground infrastructure that it is today.This Aurora, Ill.-based business is one of a handful of companies that drew its first breaths at the onset of the trenchless technology revolution…
