Available in PDF, EPUB and Kindle. Book excerpt: The Renewal of Stormwater Systems Using Trenchless Technologies summarizes technologies used for the renewal of stormwater systems, including new, emerging, and underutilized trenchless methods, and identifies future research needs. Both trenchless replacement and trenchless renewal methods can reduce negative impacts associated with surface disruption by moving the work area outside of the travel lanes and concentrating the construction impacts off the roadway. Trenchless renewal can extend the service life of existing stormwater facilities by addressing decay such as corrosion, abrasion, and erosion; reducing or eliminating infiltration and exfiltration; and providing a structural repair or improving the structural capacity of culverts, pipelines, manholes, and related stormwater structures. In some situations, trenchless renewal can even improve the hydraulic capacity of the stormwater system.
