Designed for optimum results

• Constant filtration, with skimming via the overflow
• Calming inlet ensures that water entering the tank, even during the heaviest downpours, does not stir up the sediment and disrupt the ecological balance in the tank
• Integrated backflow valve with rodent stop prevents contamination from the stormwater outlet
• Tank is fully sealed using positive o-rings, labyrinth or lipseal arrangements and does not rely on site-applied sealants
• Made from food-grade, UV stabilised polyethylene to meet AS4020 and will not corrode, has no fibres and will not taint the water
• Depth of tank design provides for a larger volume of clean, fresh water compared with shallower profile underground tanks
• Single-piece monolithic construction of the rotomoulded tank prevents cracking and root encroachment
• Full-size manhole allows easy access for cleaning and maintenance
• Telescopic riser, tiltable lid and the ability to flex with soil movement means the tank remains a completely sealed unit and can avoid contamination
