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.

Features and Benefits

• Prevents sediment, bird droppings, spiders, insects, mosquito eggs and debris from entering the rainwater tank.
• Improves water quality, protects pumps and internal appliances.
• Ideal to use in conjunction with a rain head.
• Perfect for sloping allotments.
• No mechanical parts.
• Inlet fits 90mm pipe or 100mm female fitting.
• Simple to install – just add 300mm diameter pipe and glue. (300mm pipe can be also be purchased from Bluewater Tanks)
• Low maintenance.
• Converts a ‘wet’ system in to a ‘dry’ system.
    

How much water to divert

It is important to prevent heavy sediments and other roof pollutants from entering the rainwater tank. It is recommended that 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) the amount 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.
