6,785 gallon rainwater system near Asilomar in PG

GSL finished installing a nice size system near Asilomar in October, 2015.  Two weeks later PG received a 2 inch rainfall and this system collected about 1,300 gallons.  The rainwater is collected from the garage roof of approximately 1,000 square feet. The garage has 5 downspouts all connected to a 4 inch drainage pipe underground that daylights out to a rain garden.  Working with the homeowner we developed a concept of intercepting the water via a sump basin and pumping it into the tank system. The main tank system includes three Bushman 1,320 gallon tanks connected via flexible PVC hose.  A remote Bushman tank with 2,825 gallon capacity sits on the other side of the yard.  A 1.5" PVC pipe with 3 water spigots is installed between the two tank areas.  The sump pump sends the rainwater into the 3 main tanks, and an irrigation pump pressurizes the 1.5 inch line that can be fed into the remote 2,825 gallon tank.  The irrigation pump is lightweight and can be connected on both sides of the 1.5 inch irrigation line.  Leaf Solution gutter filters were installed on the gutters around the garage by Noble Pride Roofing.  This provides a very fine filter and high quality rainwater to the sump basin where the sump pump pushes it into the tanks.  Six more inches of rain and all 6,785 gallons of capacity should be full.  Lots of rainwater for the beautiful gardens around the home.  Again this only collects from the separate garage.  More rainwater can be collected from the main house and will provide for a nice addition in the coming years!
