All our underground polyethylene pits are Australian made and certified under the AS/NZS1546. 1:2008 standard.

Our Stormwater and Sewer pits are NSW Health and SA Health approved. The 250L up to 8,500L pits are ultrasonically tested for wall thickness, impact tested, water leakage and top load tested. The tank design is carried out with a Finite Element Analysis (FEA) study. The site conditions are simulated and measured against the strength and long term specifications of the material.

In addition to the standard, the manufacturing procedures are audited by SAI Global. Eco Building Supplies is proud of its quality products and outstanding customer service.
