University of Alberta
OP-23: Rainwater Management

- In 2013, an underground cistern was installed on the west side of the Centennial Centre for Interdisciplinary Science (CCIS). The cistern is used to store water collected during fire pump testing. The water is then used in watering trucks to meet some of the university's irrigation needs. - Augustana Campus has one 1500 gallon underground tank that collects water from the campus’ grass swales, two 250 gallon above ground tanks which collect rain water from the roof of the Facilities Building, and an additional 100 gallon tank which collexts rain water from the Auxiliary Building. The water that is collected is used for irrigation on campus. - The Campus Community Gardens on both North Campus and Campus Saint-Jean are irrigated with rainwater collected in barrels. - 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. - The University of Alberta Botanic Garden has slow ditches, a parking lot runoff collection well and buffered riparian areas to help manage groundwater.

LONG RANGE DEVELOPMENT PLANS AND SECTOR PLANS https://www.ualberta.ca/vice-president-facilities-operations/forms-and-documents.html NORTH CAMPUS, SOUTH CAMPUS, CAMPUS SAINT-JEAN AND MICHENER PARK The Long Range Development Plan (LRDP) for North Campus, South Campus, Michener Park and Campus Saint-Jean 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 The Sector 12 Campus Planning and Design Guidelines for Implementation accompanies the South Campus Sector Plan, and outlines the strategy for the execution of the University of Alberta’s South Campus Sector Plan. It includes existing and proposed stormwater management facilities for South Campus and a three goals with respect to water and stormwater management: - Provide an environmentally sensitive stormwater management approach that filters water quality - Reduce potable water use on campus - Provide opportunities to recharge groundwater. AUGUSTANA CAMPUS There is a separate LRDP for Augustana Campus (Augustana LRDP, 2005 and Augustana LRDP Amendment, 2018). In 2008, Focus Corporation developed a Stormwater Management Plan for Augustana Campus to accompany the Augustana LRDP. The Augustana Campus Stormwater Management Plan provided a framework for development to the year 2015. The proposed stormwater management concept included a wet Storm Water Management Facility, three dry ponds, and a drainage swale. All of these components of the Stormwater Management Plan have been implemented, as well as an additional dry pond and bioswale.
