This highly visible facility required the ultimate in sustainable solutions, resulting in state-of-the-art waterworks. Designed to LEED Gold standards, the new drinking water filtration project in North Vancouver’s Lower Seymour Conservation Reserve is the largest in Canada and has attracted international attention as a case study for its cutting-edge approach to sustainable design and safeguarding concepts. Filtering up to 1.8 billion litres of water a day, it includes the world’s largest ultraviolet (UV) disinfection system as well as the first geo-exchange energy system in a facility of its kind in British Columbia.
