Which of the following best describes the institution’s approach to rainwater management?:
No written policies, plans or guidelines, but green infrastructure and LID practices are used

A brief description of the institution’s green infrastructure and LID practices:

Some of the ways that RRC Polytech uses green infrastructure to manage rainwater and employs LID practices are listed below:

- The Vehicle Technology & Energy Centre (VTEC) is LEED Silver certified. It features controlled flow roof drainage and vegetative plantings around the site to slow the flow of runoff and reduces the volume of water entering the sewer system by 27%. The plants in the surrounding garden require little maintenance and are drought tolerant — making them suited to Winnipeg’s hot summers and cold, snowy winters. Water savings are substantial because they don’t need irrigation.

- The Skilled Trades and Technology Centre (STTC) is LEED Gold certified. It features a “LiveRoof” modular green roof system acts like a sponge and absorbs excess rainwater, reducing the impacts on storm sewers. A passive storm water management system includes a rain garden monitored by RRC Polytech students, plus a bioswale leading to a meadow with native and adaptive prairie tall grass.

The entire landscape at STTC was designed as a living laboratory for RRC Polytech’s Indigenous programs. There are over 120 trees, 750 shrubs, 2,500 perennials and 2,200 square metres of prairie seed mix in the student courtyard, including 40 species of locally-developed prairie hardy fruiting trees, shrubs and vines. A xeriscaping test garden runs along the entire south face of the STTC and uses native and adaptive ornamental shrubs and perennials developed in Manitoba. The student courtyard features specialized planting details using root growth trenches to help the trees thrive under a paved surface.

- The Roblin Centre features a small demonstration green roof reduces the heating and cooling loads of the building and absorbs stormwater and snow.
- The park adjacent to Paterson GlobalFoods Institute (PGI), which is LEED Gold Certified, includes several native grasses and hardy, drought-tolerant plants that require no permanent irrigation equipment.
- At the recently opened Manitou a bi Bii daziigae, water from roof and weeping tile pits gets filtered and then stored in 2,000 cistern in the crawlspace beneath the building. Water gets transferred from cistern to 500 gallon day tank and chemically treated for use in toilets.
