askACO to propose the correct drain size for your next project

trench hydraulicsACO can provide accurate channel recommendations with its proprietary drainage design software.

‘Hydro’ is a purpose written, hydraulic design program modelled on differential calculus for non-uniform flow in open channels. The program was further refined with empirical data, following a series of experiments modelling lateral intake into trenches.

askACO to propose the correct inlet size grate for your next project

grate hydraulicsACO can provide accurate grate recommendations with its proprietary software. The hydraulic intake capacities of ACO’s grates have been independently measured by experimentation at the UNSW under varying flow rates and catchment approach slopes.
