Are slot drains available for plazas where a standard grate would be unsightly?

Yes. ACO Brickslot is a narrow slot-drain top for KlassikDrain channels, including a heel-resistant version suited to crowd areas, and it reduces the visible drain line to a discreet slot in the paving. It is available through our quote desk.

Stadium & Recreation Drainage

Q: What load class does a stadium concourse need?

Concourses and plazas are pedestrian surfaces, but most venues spec Class B or higher because sweepers, utility carts, and stocking vehicles use the same routes after hours. Service tunnels and loading areas that see trucks belong in Class C or above. The Load Class Recommendation Guide covers the full range.

Q: How do you drain natural-turf fields and grounds?

Surface water on turf and landscaped grounds is collected at low points with catch basins, carried in buried pipe, and released downslope through pop-up emitters or infiltrated through dry wells where there is no practical discharge point.

Drainage by Application · Stadiums & Recreation

Concourses that move tens of thousands of people in minutes, service tunnels shared with trucks, playing surfaces that cannot hold water, and an event calendar that does not move. Here is how stadiums, arenas, and recreation facilities spec drainage that keeps the schedule.

What fails at a venue — and why it matters more here

A venue concentrates two problems most sites never see at once: enormous paved areas that shed storm water all at the same moment, and crowd movement that cannot be detoured around a flooded gate or a closed concourse. Ponding at an entry plaza slows egress, wet concrete around concessions becomes a slip hazard by the second inning, and a saturated field or fairway cancels revenue outright. The same drain lines also have to survive sweepers, scissor lifts, and delivery trucks after hours — so the load rating, not just the flow rate, decides what gets installed.

Load classes around a venue

Concourses, plazas, and gates are pedestrian surfaces, but most venues spec Class B or higher because utility carts and sweepers run the same routes every night. Service tunnels, loading docks, and staging areas that see trucks belong in Class C or above; routes rated for fire apparatus or broadcast vehicles need heavier classes still. Match each surface with our Load Class Recommendation Guide before selecting grates.

Concourses, plazas & gates Quote line

ACO KlassikDrain modular trench drain is the standard answer for high-traffic public concourse work, with grate packages from pedestrian to heavy-duty. Where a visible grate would fight the architecture, ACO's Brickslot slot-drain tops — including a heel-resistant version for crowd areas — reduce the drain to a narrow slot in the paving. Grate openings on accessible routes must also meet ADA rules; see our ADA drainage guide. Request a quote with run lengths and traffic types.

Service tunnels, docks & event staging Quote line

Back-of-house routes carry box trucks, forklifts, and broadcast units on a deadline. ACO PowerDrain is the heavy-vehicular member of the ACO family, built for these loads with ductile iron grate options. It is quote-only — send the run length and vehicle types and we will spec channel, grates, and accessories.

Recreation slabs, aquatic centers & practice facilities

For pool surrounds, locker-room aprons, splash pads, and practice-building slabs, NDS Dura-Slope trench drain offers a pre-sloped channel system with a deep grate catalog, and the lighter NDS Pro Series covers walkway and light-vehicle runs. Both are stocked, cart-ready lines.

Fields, turf & grounds

Turf drainage is collection and disposal: catch basins at the low points, buried pipe to carry the water, pop-up emitters where it can daylight, and dry wells where it cannot. Atrium grates keep leaves and mulch out of basin inlets in planted areas — the same kit that keeps golf courses, ballfields, and park grounds playable after a storm.

Drainage installation in a golf course sand trap — Sand-trap drainage installation on a golf course — collection at the low point, buried pipe out.

Planning tip: venue hardscapes shed huge volumes at once. Estimate the storm flow for each catchment with the runoff calculator before sizing channels or basin outlets.
