Large volume first flush diversion made easy. The First Flush Delta Post / Wall incorporates a revolutionary chamber design that uses 100mm pipe for simple installation and high volume diversion. Every 1m of Delta chamber = 73 litres of diversion!

First flush diversion protects your rainwater quality by minimising the volume of suspended and dissolved fine particles that end up in the water you harvest.

A vital part in any Rain Harvesting system, first flush diverters channel, capture and isolate the most contaminated rainwater from your roof in special diversion chambers.  You can then manually empty this water or automatically release it into stormwater or your garden.

First Flush Diverters help divert the first flush, through their design. They are installed using a T junction or high flow inlet to which the diversion chamber is fitted. As the chamber fills with the initial dirty water from your roof, a ball rises until it seals the inlet, allowing the rest of your rainwater, which is much cleaner, to flow directly to your tank.
