300mm in ground first flush water diverter kit

Buried and out of sight, In-Ground Water Diverters are perfect for sloping allotments. On a site that provides the opportunity for the end cap of the diverter to be positioned above ground (to drain out and be accessible for maintenance), an In-Ground Diverter allows a ‘wet’ system to be converted into a ‘dry’ system.
Most systems are ‘wet’ due to the size of buildings, and the placement of tanks away from the buildings mean that there are long runs of pipe underground leading to a riser at the tank. On a sloping site this diverter ensures the diverted water and the water that would normally remain in the pipes empties out. The result – a ‘dry’ system that improves water quality.


How much water to divert
It is important to prevent heavy sediments and other roof pollutants from entering the rainwater tank. The amount of water diverted should be a minimum of 20 litres per 100 square metres of roof area (or 0.2L per m2). In calculating the amount of water to divert, consideration can be given to (1) the surface area of the roof, and (2) theamount of pollutants on the roof and gutters.
The following factors can be used as a guide in determining the volume of water to be diverted.
As a rule of thumb, the more water that is diverted the better the quality of water in the tank.
Multi pipe feed systems
These water diverters can handle more than one pipe
Single or multiple pipes carrying water from the roof can be directed into an In-Ground Water Diverter.
