When it comes to sanitary sewers, it is often “out of sight, out of mind” for most residents, businesses, and elected officials until a problem arises. In many locations, sanitary sewers approaching 130 years are still in active use even though they are beyond their useful life. Sanitary sewers in poor condition allow inflow and infiltration to enter the sanitary sewer pipes resulting in basement back-ups, or sanitary sewer overflows which impact human and aquatic life. 

 

We understand the importance of the condition, connectivity, and defects of an existing collection sewer system and the various methods of repairing and replacing aging sewer systems.
