Not sure where your project fits?

Bring a site sketch, photos, and these three sets of information. A surface span or grate rating alone cannot select a drainage system.

Check inlet capture and bypass, channel capacity, outlets, downstream water levels, and a safe overflow route if collection blocks or is exceeded. FHWA HEC-22 covers the stormwater design process. Apply the project’s local codes, permits, and agency criteria.

Plan grate removal and solids cleaning. Check body, grate, seals, and connections against actual chemicals, concentrations, temperatures, and contact times. Wet rooms also need a matched floor or waterproofing connection. On accessible routes, check installed openings, orientation, transitions, and slip resistance against the applicable surface requirements; human access labels do not establish hoof or paw safety.

Establish approved reuse, treatment, containment, or disposal before connecting washwater, process waste, or spill collection. A drain, basket, or oil-water separator does not authorize discharge or remove every pollutant. EPA pretreatment prohibitions apply to nondomestic wastewater entering public treatment works. Some areas are better served by covered containment and controlled recovery than an open drain.

Compare the collection method, then the product

For surface runoff, compare NDS catch basins at low points with NDS, BG Filcoten, Josam, and ACO channels along interception lines. Roof drainage, saturated soil, and suspended decks need their own collection details. Dry wells or infiltration landscapes need suitable soils, groundwater clearance, and water quality, plus storage and overflow planning.

For washable interiors, compare the catalog’s ACO sanitary point drains, floor sinks, and linear drains. Stainless rails or grates on a general-purpose channel do not provide the same construction. Openable channels and slots need different inspection and cleaning arrangements. Where dedicated cleaning equipment is useful, Slot Drain Systems 10,000 Series is an option beyond our catalog with an optional clean-in-place system to compare with ACO’s options; verify the sanitation workflow and cleaning access for either design.

Collection, treatment, and spill protection serve different duties. Compare ACO oil-water separation and spill-control products and Aquaduct Double Containment against the actual liquid and failure scenario. Pumping, washwater reclaim, or other treatment may need additional equipment. The application guides develop these choices for each setting.
