SEWER REHAB NEAR MASS GENERAL HOSPITAL
Pipe Relining Eliminates Need To Dig Up Old Brick Sewer Near Hospital’s Entrance
Problem: Deteriorated and leaking brick sewer interceptor serving Massachusetts General Hospital and located in front of the ER entrance.
Solution: Quadex Lining System® (QLS) GeoKrete® was applied in areas where CIPP could not be performed due to headwalls and other obstructions. The versatile application options of QLS/GeoKrete allow the non-round sections of the interceptor to be fully restored when there was no other viable option. Traditional CIPP was installed in rounded sections of interceptor.

Trenchless Rehabilitation Services
Full Pipe Rehabilitation
Cured-In-Place Pipe (CIPP) state-of-the-art liner rehabilitates pipe quickly and easily using a trenchless installation process. Installed through the manhole, this product creates a structural, tight fit, resin-based liner inside of the host pipe. CIPP prevents infiltration and exfiltration, and restores structural integrity.
Glass-Reinforced Pipe (GRP) relining uses a thermosetting, resin-impregnated flexible tube that is inverted and cured with hot water or steam. This exclusive technology fully integrates the unique properties of traditional felt liners with fiberglass strength, providing the strongest, most robust liner on the market.
Segmental Point/Spot Repair Solutions
Mechanical point repair solutions, including stainless-steel and PVC repair sleeve options, provide an economical method for repairing localized problems without replacing or relining the entire pipe or excavating the area around it.
Our no-dig CIPP segmental patch repair systems provide a structural repair by lining only areas that require repairs without digging the existing pipeline or lining the entire pipeline.

SSES Field Services
Tri-State Utilities offers Sewer System Evaluation Survey (SSES) field services to both engineering firms and municipalities that relate to inflow and infiltration (I & I) source identification. Tri-State Utilities employs an in-house Professional Engineer (P.E.) who can evaluate collected data and work closely with customers to help ensure rehabilitation projects are designed to meet budget and system requirements.
SSES Field Services Methods and Data Collection Technologies
- Closed-Circuit Television (CCTV) sewer inspections utilizing powerful data acquisition and management software technology to capture and store pipe data related to size, flow, direction, location and faults High-performance cleaning of sanitary and storm sewers uses high-pressure water to scour the pipes and then powerful vacuum to remove the debris and is performed with minimal disruption to traffic and the environment
- Manhole inspections utilizing high-resolution, zoom, pole cameras linked to NASSCO/MACP-compliant data management software
- Smoke testing, utilizing the Hurco liquid smoke blower, which eliminates the use of potentially toxic traditional smoke bombs
- Dye testing, with fluorescent environmentally safe dyes, to establish flow streams and uncover cross connections and system leaks
- Flow studies and night flow isolation studies to develop baseline flow characteristics and determine sources of I/I during weather events
