Once an I/I problem has been identified, there are many methods and technologies available to reduce I/I.

Pipe repair

Broken pipes, manholes, and joint connections can be repaired in a variety of ways. Trenchless repair methods require less digging than traditional “dig and replace” repair methods and minimize damage to yards and landscaping.

Pipe bursting is a technique that pulls a hardened steel breaker head through the old pipe, breaking it up, and replacing it with a new pipe all in one process.

Cured-in-place pipe (CIPP) repair involves pulling a resin-saturated liner through a damaged pipe, which is then cured with steam or hot water to form a tight-fitting, jointless replacement pipe.

Stormwater disconnections

Stormwater connections such as roof drain downspouts, yard drains, and sump pumps can be disconnected from the sewer system.

Property owners can redirect the downspouts onto lawn and garden beds, hook up a rain barrel or cistern to their downspouts, or redirect the connections to a separate stormwater system.

Contact your local sewer service provider for specific information about the sewer system in your neighborhood.
