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.

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.
