Linear Drainage for Transport Infrastructure
ACO has invested heavily to technically support its stormwater management drainage products. Staffed by qualified engineers and equipped with purpose-written computer software, a design service is offered without obligation service or fee and is presented professionally.
ACO’s Technical Services department can offer advice to ensure the correct product is chosen for the application.
Services offered include:
Project specific flow calculations to ensure correct sizing of trenches
ACO can recommend the optimum size channel based on the volume of liquid to be drained whilst taking into account other project specific factors such as rainfall intensity, catchment areas and plumbing restrictions. ACO uses its bespoke hydraulic ‘Hydro’ program to assist with calculations. This is a free service and results are provided either electronically (PDF) and/or in printout format.
Project specific grate intake calculations to provide grate catchment data
ACO has independently measured, by experimentation, the hydraulic intake capacities of all ACO grates. The Grating Intake Calculator (GIC) provides information on the intake efficiency of the chosen grate. If the required liquid intake is greater than the grate’s performance, the extent of bypass (or failure) will be calculated. This is a free service and results are provided either electronically (PDF) and/or in printout format.
Risk analysis of flood situations, including estimated flood size and duration
Temporary ponding is a short lived flood situation, which, in some circumstances, can be tolerated allowing an intentionally undersized trench drain system. It allows a more economical system to be used that will work effectively under most weather conditions, but will be slightly under designed for heavy storms. Ponding analysis should only be considered where buildings and property are not in close proximity to the drainage system to minimise risk of damage. It is an ideal option for the outer areas of large parking lots, distribution yards, etc., (Risk Analysis).
Plan and profile layouts complete with bill of materials
ACO can provide a cost-effective surface drainage solution to satisfy a project’s design requirements. Trench drain layouts will be designed to take full advantage of existing and proposed site grades, utilising existing services where possible.
