University of Alberta
OP-23: Rainwater Management

- The Campus Community Gardens on both North Campus and Campus Saint-Jean are irrigated with rainwater collected in barrels. - Augustana Campus has one 1500 gallon and two 250 gallon above ground tanks that collect water from the campus’ grass swales, and the water that is collected is used for irrigation on campus. Additionally there is a 100 gallon above ground tank to service the Augustana garden. - In 2013, an underground cistern was installed on the west side of the Centennial Centre for Interdisciplinary Science (CCIS) to collect water used in fire pump testing and then use this water for campus irrigation needs. - The Medical Isotope and Cyclotron Facility (MICF) on South Campus features a dry pond and an underground tank that collects rainwater, which is used for irrigating the surrounding landscape. - Porous paving in East Campus Village residences area allows for water to infiltrate into soil. - Triffo Hall collects rainwater in a below-grade storage tank system and uses it for toilet flushing to reduce potable water use.

NEW DEVELOPMENT: The Long Range Development Plans for the University of Alberta encompasses North Campus, South Campus, Michener Park and Campus Saint-Jean. The LRDP identifies where on-site stormwater management will be necessary and where existing facilities can be utilized; it states that stormwater management facilities will be developed as warranted and will be staged incrementally to minimize servicing costs. Additionally, wherever possible, the stormwater management system will be connected to the open space system. Accompanying the LRDP are sector plans that further detail specific strategies and methods that will be used to address stormwater management, such as: - aquatic vegetation and designed ecosystems in naturalized stormwater management facilities - rainwater collection systems - xeriscaping - grey water systems, and - rooftop gardens/vegetated roofs There is a separate LRDP for Augustana Campus (Augustana LRDP, 2005), and in 2008 Focus Corporation developed a Stormwater Management Plan for Augustana Campus to accompany the Augustana LRDP. The Augustana Campus Stormwater Management Plan provides a framework for development to the year 2015. The proposed stormwater management concept includes a wet Storm Water Management Facility (SWMF) located at the downstream end of the ravine, a dry pond that will service the campus catchment draining to 46th Avenue, and two dry ponds for the residence parking lot expansion draining to the CN Railway ditch. A drainage swale proposed for the west side of the campus will intercept and direct runoff to the ravine SWMF. The plan also covers erosion issues. CURRENT PRACTICES: Initiatives already in place include the following, with more detail in the sections below: - a vegetated roof - retention ponds - stone swales - vegetated swales - underground cisterns - rain barrels in our Community Gardens - permeable hard surfacing - rainwater harvesting - bioswales
