High Water Mark Achieved in Record Setting Rain

We all know fresh water is a precious commodity in So. California.  Hearing what the TreePeople are doing to harvest rainwater and manage the overflow on site to replenish the aquifer sounds like a good idea.  This benefits the ocean water quality by keeping that storm from running into the street and washing oil, pesticides…down to the beach.

We just didn’t know if our soil could handle the volume of water from our roof without overflowing into the street.  The record rains gave us the ideal test.  As you can see from the photos of our trench test, even when fully saturated, our soil allows for perfect percolation in just a couple of hours.
