Vegetal I.D. Partners with Local Organizations to Pilot New Stormwater Management Solution
Vegetal i.D. has announced a collaboration between the Milwaukee Metropolitan Sewerage District (MMSD), Fund For Lake Michigan, The Water Council, UW-Milwaukee, and UW-Whitewater to closely monitor the performance of a new stormwater management solution. The technology being tested is an advanced system combining a blue roof with a green roof that is poised to bring green roof based stormwater management performance to a whole new level.
Green and blue roofs are a component of a new form of low-cost high-impact stormwater management known as green infrastructure. The goal of green infrastructure programs is to mimic natural systems in order to manage stormwater on-site and minimize problems such as polluted runoff and basement backups.
The alternative solution involves the expansion and maintenance of traditional grey infrastructure systems, which can be extremely expensive and often does not completely solve the problem. This is why cities are turning to green infrastructure systems such as green roofs to deal with rainwater at the source, and minimize taxpayer expenses.
In Greater Milwaukee Area of Wisconsin, the Milwaukee Metropolitan Sewerage District has spearheaded the green infrastructure movement for over 10 years. The goal, known as Fresh Coast 740 is to capture 740 million gallons of water every time it rains. To achieve this goal the program invests in high impact green infrastructure such as rainwater harvesting, porous pavement, and bio-swales and by obtaining key pieces of land to remediate into greenways and wetlands that manage great amounts of stormwater naturally and increases resistance to flooding.
Green roofs are a part of the green infrastructure solution. They absorb and retain water on the roof and use it to grow plants that cool cities, clean water, add biodiversity to urban areas, and improve property values. "Green roofs are like sponges and absorb lots of water, but when the soil is fully saturated from previous rainfall, it doesn't have much effect," according to Gaëlle Bergès, of Vegetal i.D. This is why Vegetal i.D. is launching a new stormwater management compliment to green roof systems known asSTOCK & FLOW
