BACKGROUND:
After the flooding event in April 2013, the Water Utilities rehabilitated all mainline sanitary sewer lines and manholes in Cress Creek subdivision. Staff continues to identify sources of inflow and infiltration (I & I) taking system capacity during wet weather events.
Through flow monitoring and closed-circuit televising inspection of the system, staff identified significant I & I through some sanitary sewer laterals. Grouting laterals will significantly reduce the amount of ground water into the sanitary sewer system further reducing the likelihood of basement backups or sanitary sewer overflow.
The combination of sewer and lateral lining projects in Cress Creek subdivision made significant improvements in the wastewater system by limiting infiltration of groundwater and stormwater.
In July 2020, the Water Utilities issued Bid 20-292, 2020 Lateral Grouting Cress Creek Phase 6. The work included testing and grouting of 61 sanitary sewer service laterals in the Cress Creek subdivision; all services are six-inch diameter. The lateral grouting program is part of the City's Ten-year Infiltration and Inflow Reduction Program, required and registered with the Illinois Environmental Protection Agency (IEPA).
