Does the institution use Low Impact Development (LID) practices as a matter of policy or standard practice to reduce rainwater/stormwater runoff volume and improve outgoing water quality for new construction, major renovation, and other projects?:
Yes
None
A brief description of the institution’s Low Impact Development (LID) practices:
Excerpt from Campus Master Plan
"In the management of stormwater on site, UOIT 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."
None
Has the institution adopted a rainwater/stormwater management policy, plan, or strategies that mitigate the rainwater runoff impacts of ongoing campus operations through the use of green infrastructure? :
Yes
None
A brief description of the institution’s rainwater/stormwater management policy, plan, and/or strategies for ongoing campus operations:
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 UOIT’s 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.
None

A brief description of any rainwater filtering systems employed by the institution to treat water prior to release:
---
None
A brief description of any living or vegetated roofs on campus:
Vegetated Roofs
Four buildings are constructed with extensive
“green roofs” to total 1600 square meters. The
use of grass and soil on rooftops to aid
drainage, retain heat and improve air quality.
Roof runoff water is collected in an
underground cistern with a capacity of
250,000L. This water is then used for irrigation
and flushing within the buildings surrounding
the quad; reducing UOIT’s fresh water
consumption of treated water from municipal
sources.
None
A brief description of any porous (i.e. permeable) paving employed by the institution:
---
None
A brief description of any downspout disconnection employed by the institution:
---
None
A brief description of any rain gardens on campus:
---
None
A brief description of any stormwater retention and/or detention ponds employed by the institution:

None
A brief description of any bioswales on campus (vegetated, compost or stone):
Bioswales located in parking lots.
None
A brief description of any other rainwater management technologies or strategies employed by the institution:
