Combined Sewer Service Area Downspout Disconnection Program

DDP logo

Shorewood's combined sewer system serves the area of the Village generally located east of Oakland Avenue (map). This area has been particularly prone to basement back-ups and has long been the focus of efforts to improve system capacity (please see What's Been Done page)..

As a member community of the Milwaukee Metropolitan Sewerage District, the Village of Shorewood incorporates all District operation rules by reference in the Shorewood Village Code. MMSD Chapter 3 Management, Operations, and Maintenance of Tributary Sewers requires the disconnection of downspouts within the combined sewer service area by January 1, 2025.

Shorewood's Combined Sewer Service Area Downspout Disconnection Program was adopted by the Shorewood Village Board on February 1, 2021 and identifies the process by which the Village will comply with MMSD's rule.
