First Flush Diverters
When it rains, water builds up in the roof gutters before it flows down the downpipes. The initial runoff of water from the roof typically contains many types of dirt and debris such as decomposed insects, bird and animal droppings, and many other unpleasant and harmful substances.
A rainwater harvesting system is a great way to preserve the community water supply and possibly even save money in water costs in the long run, but you don’t want those unpleasant substances washing down into your water tank. The solution to this problem is to install a first flush diverter.

The diverter water does not need to be wasted if it diverter is equipped with an irrigation system to filter out undesirable substances.
How much water needs to be diverted in the first flush?
To prevent pollutants and sediments from entering the main water supply, the amount of diverted water should be at least 20 liters of water per 100 square meters of roof surface.
If there is excessive debris on the roof, the diverted quantity of water should be even greater. For minimal pollution, divert 0.5 liters per square meter, and for heavy pollution divert up to 2 liters per square meter.
How is the first flush diverter installed?
Determine the correct length for the converter chamber and make sure it is at least 150mm above the ground to allow enough space for removal and cleaning. Install the ball and seat into the tee junction. Fix the chamber to the wall with wall brackets and connect to the down pipe with via an elbow tube. Insert the correct flow control valve into the hose connector, and install the filter screen. Place the sealing ball into the diverter chamber
If you are not confident in your ability to install the diverter yourself, hire an expert to do it for you.
