Despite massive investments in gray infrastructure, the Milwaukee Metropolitan Sewerage District faced 50 to 60 sewer overflows per year. Supplementing the grey infrastructure investment with green infrastructure – including bioswales, permeable pavement, stormwater trees, rain gardens, and more – the utility reduced overflows to an average of only 2 overflows per year. MMSD’s investment in green infrastructure could reduce the utility’s future infrastructure costs. In particular, an investment of $178 million for green infrastructure in the agency’s combined sewer service area would result in stormwater capture equivalent to $222 million investment in gray infrastructure.
