Advanced Filter Underdrain Technology for Superior Water Treatment Performance
Our Stainless Steel Underdrain System is a proven filter underdrain solution designed to maximise filtration performance through guaranteed uniform hydraulic distribution, low-profile design, and robust stainless steel construction.

Key Features and Benefits

• Custom-engineered design tailored to suit virtually any filter configuration, including irregular-shaped filters and retrofit applications (not a mass produced product).
• No microplastic liability.
• Ultra-low profile laterals, available as low as 76 mm high, maximising available filter freeboard and media depth to fit into old filter structures to increase media depth to improve filtered water quality.
• Separate air and water chambers provide independent distribution, eliminating air scour wave action and ensuring efficient backwash operation.
• Low-profile design can reduce filter wall heights by up to 1 metre compared to concrete plenum underdrain systems, significantly lowering construction costs and project complexity.
• Fast installation compared with other type of underdrain system on the market
