Rainwater that falls on the roof of the House of
Loreto will flow through the columns to an un-
derground cistern that will store the water for
use on the grounds. A hose will be attached to
the cistern for watering the gardens. This will
assist in the mission of capturing rainwater to
avoid erosion of soil and runoff into the Wissahickon.
The Philadelphia Water Department and the Wissahickon Watershed Alliance have worked hard to reduce the amount of water lost by poor drainage and impermeable paving.
