Qmax

High capacity slot drainage system

ACO Qmax has been developed to satisfy the demand for a versatile, high capacity slot drainage system for a wide range of applications involving small to large catchment areas to any load class. 

The system is specifically designed to form an integral part of any modern, sustainable surface water management solution requiring effective storage, attenuation and eliminating carry over in stormwater conditions.

The ACO Qmax system provides optimum surface water drainage and attenuation for a wide range of infrastructure, industrial, hard landscaped and other SuDS applications.

  • Available in sizes: 150, 225, 350, 550, 700 and 900
  • Supports all Load Classes up to and including F 900
  • Each size within the ACO Qmax range is CE marked and certified to BS EN1433:2002
ACO Qmax - on the right line

ACO Qmax ease of design

Available in 6 sizes, the range ensures greater flexibility in design for engineers and designers, can help minimise the number of drainage runs required in a project and greatly simplify connecting to the existing infrastructure.
