underground retention

Permeable eco-pavers allow water to soak into the ground, and underground retention tanks store rainwater for slow release.

The landscaped basins delay and reduce peak storm water flows, thereby eliminating the need to construct a traditional underground retention system of concrete ducts.

In Mississauga, several flood-prevention projects around the Cooksville Creek - which had its most dramatic flood in 2009 - were approved, including 13 underground retention ponds.
