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.
