No-dig gains ground

Article Abstract:

The Environmental Protection Agency approved a five-year program for reduction of infiltration/inflow (I/I) and cost-effective, long term repairs in Miami-Dade's gravity sewer collection system. This has helped reduce 1 mgd of I/I per month, with 55% of the repairs being trenchless repairs. The other repairs are dig and replace point, line replacement, service laterals repair and replacement. Factors such as the severity of the defect, depth of the sewer, the number of defects in the line segment, etc., influence the choice of a repair method, with cost determining the particular method via the trade-off route.

An interception by Boston

Article Abstract:

The Boston Water and Sewer Commission has initiated a rehabilitation program for 5000 m of corridors of the St. James Avenue sewer system in Boston. The system is physically and hydraulically exhausted with ground water flowing into it, thereby endangering the city living. A design which intends to minimize the disruption of sewer and storm drain has been developed. It utilizes many trenchless methods such as shotcrete lining, cured-in-place pipelining, pipe bursting and microtunneling.
