RotoTank ™, First Flush system, harvesting water

What is a RotoTank ™ First flush?


Essentially it is a system designed to divert debris from your roof so it can settle in a container, and only clean water can flow into your rainwater harvesting tank, as the debris settles it collects at the base of the system and can be flushed away.

Why do we use a First Flush System?

First flush systems are a critical part of your rainwater harvesting system, the RotoTank ™ First Flush system helps to divert the sediment filled water to a holding 50 litre wall mounted Tank, as the tank fills the sediment settles at the base of the tank, the tank has been designed to allow the sediment to settle down to a central point where a fitting can then connect to the supplied tap at which point you can then connect a hose pipe.   As the water rises in the tank the sediment settles, ultimately the clean water diverts to your rainwater harvesting tank and you prevent these contaminants from going into your system.
