Book Description
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.

Book Description
Drainage infrastructure systems (culvert, storm sewer, outfall and related drainage elements) are mostly buried underground and are in need of special attention in terms of proactive/preventive asset management strategy. Drainage infrastructure systems represent an integral portion of roadway assets that routinely require inspection, maintenance, repair and renewal. Further challenges are the wide geospatial distribution of these infrastructure assets and environmental exposure. There has been considerable research conducted on culverts, but mostly looked at the problem from a traditional structural/geotechnical perspective. Asset management procedures for culverts and drainage infrastructure systems are complex issues, and can benefit a great deal from an optimal asset management program that draws from programs pertaining to buried pipes. The first and most important step in an asset management initiative is the establishment of mechanism for asset inventory and asset conditions in a format compatible with the routine procedures of field operators and inspectors. The first objective of this research project was to develop field protocols and operational business rules for inventory data collection and management and inspection of drainage infrastructures in terms of types of data to be collected, frequency of inspection, and analysis and reporting mechanisms. After review of these protocols by the project oversight committee, a pilot study was conducted to verify efficiency of their implementation. The condition assessment protocol introduced is useful in evaluating the overall condition of culverts and can be used for decision making regarding the repair, renewal or replacement of culverts. For the second objective of this project, investigators examined the inventory and inspection protocols employed by Ohio Department of Transportation (ODOT) and developed a decision support platform, which establishes a link between the inspection results and appropriate repair, renewal and replacement procedures. After applying the recommended procedures, the transportation agencies can better track the conditions of culverts thereby reducing the risks of culvert failures.

Book Description
Due to an aging and rapidly deteriorating transportation infrastructure, agencies are facing the challenge of making quick and reliable decisions regarding the repair and renewal of their assets. While comprehensive asset management strategies have been developed for the visible components of the highway system, such as bridges and pavement, culverts and drainage structures are often neglected. The investigators recently completed an MRUTC project in which they have investigated the current culvert asset management practices of transportation agencies and also developed the inventory and inspection protocols necessary for establishing an effective culvert asset management program. This study builds upon the findings of the previous research project and focuses on the application of trenchless technologies for inspection, construction, repair and renewal of culverts. A literature search, a survey of departments of transportation and a survey of technology providers have been conducted to identify and characterize trenchless technology methods used for buried pipes. The limitations of trenchless technologies in terms of applicability to culverts are investigated.

Book Description
The Naval Air Warfare Center (NAWC) at Trenton, NJ is a gas turbine engine testing facility. Trichloroethene (TCE) is used as a heat exchange medium during engine testing. As part of an on- going environmental investigation program, TCE was found in groundwater and in water discharging from the outfalls of the facility's storm water collection system. Because of high groundwater levels, it was unclear whether the TCE in the outfall discharge was entering the storm sewers via pipe connections and/or from impacted groundwater infiltrating deteriorated sewer lines. The main storm sewer lines associated with two of the facility's four outfalls, i.e., in the areas of highest TCE concentrations in groundwater, were video inspected. Structural deficiencies ranging from cracked pipe and failed joints to total collapse were found. The rehabilitation of these lines was deemed to be an important part of the facility's remediation plans. Due to the disadvantages associated with conventional pipe excavation and replacement techniques at this site, in-situ rehabilitation alternatives were considered. Cured-in-place pipe (CIPP) technology was selected as the best alternative. This technology involves the formation of a new CIPP inside an existing pipe using a novel inversion" process. The disadvantages of excavating contaminated soil to repair the deteriorated storm sewer lines were avoided. Approximately 1,900 lineal feet of pipe, ranging from 8 inches to 27 inches in diameter, were repaired using the CIPP method. A reduction in the infiltration of groundwater into the storm sewer system, and a corresponding reduction in the TCE at the outfall, was observed as a result of the repair work.
