Rain Harvest Sediment Filter and Barrel Storage




We have a well pump that irrigates our 1/2 acre property from a ready supply of the San Joaquin River. I would never want to drink this water, but with the current drought I have also become more aware of just how important water is to quality of life in California. Of course, the state has been in a drought perhaps the majority of years of my life, so to better appreciate the water that falls in form of rain, I'm going to capture some of that which falls on the asphalt shingle roof of my garage. If I can harvest and store for the middle of summer a hundred gallons of water, maybe the irrigation pump will burn a little less electricity...

    How about putting rocks, like lava rocks for light weight, to help filter out both sediment and floating debris? With the rocks higher than the outlet it would keep floating debris from filling or blocking the outlet.

    I've improved the system so that the sediment bucket provides both outflow to the barrels and overflow, in case the barrels are filled to capacity. Be sure to save all the rubber from toilet and other plumbing as these parts can be useful in making sure connections are leak proof, as shown in this slideshow. I replaced a fabric screen filter with a couple of aluminum screen filters, 1 inside the pipe, and 1 at the intake. Note also that I included a 1/2 inch fawcett on the sediment bucket, so that the 2 gallons of mirky water can be drained and tossed on a thirsty plant.

    Nice design. So the sediment stays in the bucket while the water enters the pipe into the barrel. What about floating debris (leaves, etc)? You could add a piece of screen across the pipe. That would also keep out mosquitos that may try to breed in the water. You'd also need to add some screen over the open end of the T-fitting on the secondary barrel (left side of third pic).

    Thanks for the comment. It was hard to shown the photo but there is a piece of filter fabric between the threaded fittings on the intake. It's important also to use 2 inch PVC because toilet rubber rings can be used to prevent a leak at this spot. Another adjustment from this photo is the overflow pipe height, which had to reduced else overflow would be at the bucket. The open T is for add-on of another barrel. In the short term this can be capped off. Note that none of the fittings are glued as yet.
