Milwaukee Metropolitan Sewerage District (MMSD) is a regional government agency that provides water reclamation and flood management services for about 1.1 million customers in 28 communities in the greater Milwaukee area. MMSD serves 411 square miles that covers all, or segments of, six watersheds.
MMSD's mission is to cost-effectively protect public health and the environment, prevent pollution and enhance the quality of area waterways and, in many ways, this project is a perfect fit. The installation of a solar PV system on the roof of the Dewatering and Drying Building on Jones Island assists in reducing greenhouse gases, which helps protect the public health. In addition, better air quality leads to better water quality. Air particulates affect the heath of all plants and animals, whether above or below ground. Therefore, the District felt it was its duty to be concerned about pollution and pro-active in ways to mitigate its effects.
