When McMaster University in Hamilton, Ontario, Canada, set about constructing its new Engineering Technology Building, it used the latest state-of-the-art technology not only to achieve U.S. Green Building Council Leadership in Energy and Environmental Design (LEED) Gold certification, but also to create a living laboratory to train students on the building systems of the future. One of the components is a rainwater harvesting system that collects, filters and disinfects rainwater for non-potable and potable use in the building.
First-of-its-kind system treats rainwater for potable reuse
The Equaris Enfinity Plus greywater recycling system filters, disinfects with ozone and supplies reverse osmosis water to every plumbing fixture, including drinking water. Milking as much permeate water as possible out of the concentrate and using the high-TDS water to flush the toilets has documented a 99% reduction in the need for water by totally recycling the greywater.
As water resources become scarcer, municipalities across the country are looking for ways to conserve water and reduce pollution. The Milwaukee Metropolitan Sewerage District (MMSD) got the community involved by introducing rain barrels, an inexpensive method that manages pollution by reusing rainwater.
Rain barrels are a cost-effective way to help the environment
What do you know about rainwater harvesting? This is a question you will start hearing soon from your customers.
As water conservation generates a higher profile in the media, more and more consumers, like the residents of Milwaukee, are interested in embarking on do-it-yourself conservation and reuse projects. Our cover story, “Simple Water Savings," details the success that the Milwaukee Metropolitan Sewerage District has found with their thriving rain barrel program.
