Due to growth in the Twin Cities area, MCES determined they needed to construct a 50 foot deep sanitary sewer lift station, modify alignment of gravity sewers and add a 9000 foot long forcemain to handle increased volumes.

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.

These grouting projects were implemented using specifications largely consistent with the new NASSCO grouting specifications. This paper will review the requirements for testing and grouting under which the original work was done.
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.
Chemical grouting has been successfully used for over forty years to control the movement of groundwater in a wide variety of applications including tunnels, subway systems, sanitary sewers, mines and construction projects.

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.
For those who believe that grout expands and contracts with wet/dry climate cycles, Avanti commissioned an independent lab to perform field testing and analysis that proves otherwise

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.
