The Milwaukee Metropolitan Sewerage District (MMSD) launched its Green Infrastructure (GI) Program in 2002, and at the time it was met with considerable skepticism. MMSD recognized early on that managing water where it falls could help keep stormwater out of the region’s sewer system and prevent pollution from being carried into local rivers.

Water agencies are facing a complex mix of challenges: meeting new regulatory requirements, managing affordability for customers, and planning for long-term operations and resilience. In this environment of uncertainty and rising needs, it's key to use strategies that maximize value.
