Make a rainwater harvesting leaf skimmer

Having made the First flush diverter (FFD) we decided to tackle a leaf skimmer. The commercial units are a bit bigger and better looking but our unit worked out at less than a third of the cost and it works pretty well. The materials used were again what we had on hand and other items could be substituted. It is also a much simpler build and mechanism and compliments the FFD  rather well.

How it works.

The water from the downpipe falls through the screen/mesh and leaves are angled away by the screen.

How to make it.

We had a two PVC gutter down-pipe end and two edges.  We started with the original and attached the sides. A second  one was then adapted as follows:

Then cut out a square leaving the wall side intact. Keep the plastic as you need to cut two strips from it to secure the mesh. Hold the net (we used excess plastic netting  that was bought  to stop the cat going out the gate) in place and rivet the plastic strips to the main body.

Use additional plastic strips to rivet the top and bottom half of the skimmer together. Take the unit and silicon /glue to the pipe feeding the FFD.
