Developers in Alberta, Canada are embracing cutting edge alternative stormwater technologies, according to a recent study by the University of British Columbia.

The study found that Alberta, along with two other Canadian provinces, is adopting widespread use of low-impact developments (LIDs) in urban planning and new community design. LID refers to site design practices that reduce the impact of water runoff and allow the water cycle to flow more smoothly.

According to the Calgary Herald, Qualico Communities of Harmony, a new master-planned lake and golf community in Calgary’s Springbank area, demonstrates cutting-edge sustainability features. Harmony utilizes an integrated water strategy.

All water conveyance in Harmony is handled through a series of catchment areas that lead to medium-sized wetland areas, which then lead to larger-sized wetland areas, the article states. The storm water is filtered through natural grasses, mud and sand. The design is beautiful, creates a nature-filled amenity space for residents and attracts abundant wildlife and birds, while efficiently filtering, and cleaning storm water.

In addition, water flows from the wetlands into a man-made lake, where it is filtered further and then ozonated. An onsite water treatment plant, one of the most advanced in North America, then cleans the water using a bio-membrane filtration system.
