Beach Road and Lemaster Avenue Sanitary Sewer Improvements



“Beach Road and Lemaster Avenue Sanitary Sewer Improvements”
Foxridge, Woodland Road and Fox Hill Gravity Sewer Rehabilitation
HRSD Capital Improvement Program Project (YR010300)


HRSD is undertaking a project to rehabilitate gravity sewer pipes along Beach Road from Westlawn to Silver Isles Boulevard with some work occurring on Silver Isles Boulevard and Lemaster Avenue. This effort will increase the system lifespan while decreasing inflow and infiltration and decreasing risk of failures. Reducing inflow and infiltration of rainwater into the sewer system should help reduce the risk of sanitary sewer overflows during heavy rain events such as Nor’easters or hurricanes. The Cure in Place Pipe (CIPP) system is anticipated to be used to accomplish this task. CIPP is one of several trenchless methods used to rehabilitate existing pipelines. Little to no digging is involved in this process, making it potentially more cost-effective and less disruptive than traditional "dig and replace" pipe repair methods. CIPP is a jointless, seamless, “pipe-within-a-pipe” process.


The sewer must first be prepared for lining; this includes cleaning the line, removing roots, sediment, and grease from the sewer (public and/or private lines) and cutting out intruding connections. The sewer lines and manholes are inspected using closed circuit television (CCTV). Like many types of pipe renewal/replacement, CIPP requires bypass pumping, which re-routes sewer flow around the section of pipe being rehabilitated. This ensures your sewer service is not interrupted. The lining process involves the insertion of a resin-saturated flexible lining into an existing sewer pipe using the manholes located within the street. The lining looks like a very large sock or flexible tube. Either air or water, under pressure, is forced into the tube, which turns the lining inside out and causes it to expand to fit tightly against the existing sewer walls. Hot air or water is circulated throughout the tube to harden the resin. When the curing process is completed (4-8 hours), a new “pipe-within-a-pipe” has been created, eliminating cracks and holes that allow rainwater and roots to enter the sewer and cause operational problems such as stoppages and overflows.
