Excerpt from Campus Master Plan
"In the management of stormwater on site, Ontario Tech U should, wherever possible apply low impact development (LID) principles. This will help to mitigate reductions to groundwater recharge due to the increase in imperviousness caused by the proposed development. Additional guidelines relating to LID principles and criteria are identified in Section 3.1."

A brief description of the institution’s rainwater management policy, plan, and/or guidelines that supports the responses above:

Storm Water Collection & Management
Each building has been designed with a second plumbing
system that collects storm water from the roofs and
stores it in a 250,000L underground cistern. This water is
then used for irrigation and flushing within the buildings
surrounding the quad; reducing the campus' fresh water
consumption of treated water from municipal sources.
Grey Water Collection & Management
The aquatic toxicology lab uses approximately 88,000L of
fresh water per day. This water is supplied by the
municipality in order to ensure high quality, low-in-metals
water. This water is further filtered for use within the lab
with the Grey water leaving the lab it is then directed to
the 250,000L underground cistern, where it is reused. The
stored Grey water is then used within the buildings for toilets and urinals.
