The site’s tight constraints made Rainstore3 an good choice. Nine units high and the small footprint could still hold all the site’s stormwater for a 10 year storm. The Rainstore3 chamber is under parking bays at the site.

The Rainstore3 were stacked nine units high (90 cm - 36 inches).

A layer of geogrid is placed on the bottom of the excavated ares.

A port is placed in by removing the Rainstore3 units and wrapping the geotextile fabric tightly to the pipe.

An outlet pipe is attached to the chamber.

Geogrid is placed above the entire chamber- sidefill and Rainstore3 chamber.
