Annual PPII Lateral Rehabilitation

Shorewood's 2011 Comprehensive Facility Plan included a goal to reduce inflow and infiltration (II) in the separated sewer areas of the Village by 40% by 2021. Lateral rehabilitation has been identified as a key strategy to achieve that goal.

A Private Property Lateral Rehabilitation Program (PDF) and Schedule were developed based upon the results of flow monitoring in Basins 1 and 6, both of which have been designated by MMSD as under-performing sewersheds. The schedule, illustrated at right, targets the block areas which have contributed higher-than-expected flows to the sanitary system during rainfall events during our evaluations.

The Private Property Lateral Rehabilitation Program is currently 100% funded through the MMSD and Village of Shorewood. Laterals are rehabilitated (lined) at no out-of-pocket cost to property owners identified in a specified program year.

2019 Program

The 2019 program includes a portion of the 4400 block and the 4500 block of N. Morris Boulevard in the Basin 6 sewershed. This year's construction contract has been awarded to Musson Brothers, Inc. (MBI).  Work is anticipated to begin in late August.

This year's funding was committed to the first 20 eligible property owners returning the consent form. The remaining properties have been placed on a waiting list for priority funding when the program returns to the Basin 6 area in 2021.
