The focus of the paper is to show the step-by-step progression of a private property I&I reduction program in the City of Wauwatosa. The project included soaker hose rain event simulation, lateral lining and chemical grouting.
In April 2013, Chicago and its neighboring suburbs experienced a 100-year rain event resulting in extensive flooding, sewer system surcharges, and basement back-ups.
Acrylamide chemical grout has been used successfully for over 40 years to reduce groundwater infiltration by sealing leaks and joints in mainline and lateral sanitary sewer systems.

Over the last 6 years, Malcolm Pirnie has conducted a monitoring program of cured in place mainline liners and lateral liners to assess the affect of various variables on long term liner quality, especially with regard to liner porosity/pinhole leakage.

Injection grouting is a soil sealing process used to control infiltration more effectively, more efficiently for less cost, and engineered to holistically attack all four points of entry: mainline, laterals, lateral connections, and manholes.

Wauwatosa’s short term solution - chemical grouting of sewer lateral connections to reduce I&I - has worked out so well that long-term efforts may not be needed at all.

Chemical grouting is one of the olderst techniques used to stop water infiltration into sewer collection systems, Unfortunately, it is also one of the misunderstood.
Greg Gress, manager of sewer and water for Sullivan’s Island, S.C., just completed the community’s CMOM self-assessment of its collection system. The condition assessment clearly indicated 90% of Sullivan’s Island problem was infiltration and inflow (I/I)

Think You Know Municipal Grouting? Think Again - Reeducate! To further the objectives of ICGA, reeducation is now core to its mission, as injection grouting has experienced monumental advances in the last decade, with more to come.

This year the municipal grouting industry celebrates 50 years as the original trenchless technology. It is appropriate to honor our past, but - more importantly - prepare for the future and the renewed focus on our failing infrastructure.
