#1 allows the first flush of (dirty) rainwater from the roof to go to waste so that water contaminated with bird poo, roof dust, etc doesn’t end up in your tank to form a sludge.

#2 traps leaves from the roof and gutters, preventing them from entering the pipes that carry the water into the tank.

I fitted two First Flush Diverters, one at the roof gutter and one at the tank water entrance and when we empty these after a rainfall event, the 1st one is usually quite mucky with all the sediment from the roof whereas the 2nd one at the tank entrance is relatively clean, but acts as insurance just in case the 1st one is overwhelmed. I fitted a Leaf Eater and it does a great job of preventing leaves from entering the system.
For the base, I used 8 inch treated sleepers to make a framework and filled it with Decomposed Granite and this has supported our 5000 Litre tank without any problems for the 3 years that we have had it.
I also fitted a pump and 3 taps in the garden so we can use the rainwater at mains pressure.
