Terwillegar Community Rec Centre
This $36 million LEED Silver Certified aquatic facility consists of 8 x 50-metre competition lanes, diving platforms, a leisure and wave pool with spray features, a whirlpool for 30 people, a lazy river and waterslide. For this project, the City of Edmonton was looking for a facility that exceeded the standards for pool water quality and retained AME to provide full building mechanical design including aquatic filtration and disinfection. This facility implemented Germany’s ‘Deutsches Institut Normung (DIN)’ pool standard which sets forth more stringent requirements than National Sanitation Foundation (NSF) standards. Filtration was provided by large anthracite/sand filters with carbon polish finish which has a lower micron particle removal than the traditional high-rate sand. Sanitation was provided by an electrolytic salt-chlorine system. Together, these systems have achieved superb water quality even under high municipal bathing loads.
The ventilation design at Terwillegar incorporates high efficiency condensing boilers with a cascade approach to ensure optimum efficiency within the system. Ventilation heat recovery implemented throughout also contributed to the Centre achieving LEED Silver certification.
