Monterey RWH System for raised bed garden.
The system was designed by Roger Manley of Central Coast Rainwater Harvesting and installed in May, 2010 by Garden Solutions Landscaping, 831-224-4006. This is an 1,100 gallon poly tank sitting on a compacted base for solid support. The RWH system includes a Leaf Eater and First Flush connected to the downspout supporting approximately 160 square feet of roof. 160 square feet should yield approximately 1,400 gallons of rainwater each year based on the average of 17" per year in Monterey. The first flush is connected to the tank via a "dry conveyance" through a flexible 2" hose with quick disconnects on both ends for easy maintenance. Inside the tank the incoming water goes through a "quieting" device so as not to disturb any sediment on the bottom of the tank. The Leaf Eater/First Flush assembly will collect the first two gallons of water before water is diverted into the tank. The assembly is attached to the wood siding with 2 four inch brackets and stainless steel screws. Lastly, an overflow device collects the water in the tank once it is full and diverts it to the landscape.
