Here’s a quick update to the post originally posted on 12/23/09. The garden has been renovated in November 2014, but the infiltration still is working as designed.
From December 2009: It’s raining pretty steadily today, so we rushed over to the Edward C. Little Water Recycling Facility’s OFG to see how the permeable paving and infiltration devices were holding water. Here’s what the installation looked like on the day we completed the Hands-on Workshop.
Below is a video of the devices DOING THEIR JOB sending rainwater from the roof of the adjacent 8,000 sq. ft. building (approximately 4,800 gallons per inch of rain) into the landscape and holding it there so it can infiltrate back into the ground rather than run off into the parking lot and become just more ocean pollution.
