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.
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.
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)
The birth of a specification guideline begins with a need. It is born from a process of collaboration and consensus among multi-disciplined stakeholders. After two years, the first suggested standard specification on grouting was born.
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.
