The ACO K100 Sloped Trench Drain System is a high-performance modular drainage solution designed to handle water management with efficiency and reliability. Featuring a 4-inch internal width and a continuous built-in slope of up to 130 feet, this system promotes smooth water flow and minimizes pooling.

Built with robust galvanized steel or stainless steel edge rails, it delivers long-lasting durability in demanding environments. The advanced boltless locking mechanisms, DrainLok and QuickLok®, make grate installation and removal fast and simple, while anti-shunt lugs and numbered channels ensure accurate alignment and secure grate placement.

Offering a wide range of grate styles—mesh, slotted, perforated, and ductile iron—rated up to Load Class E, the Sloped Trench Drain System adapts to a variety of applications, from commercial to heavy-duty industrial projects.

Sloped Trench Drain System: A Practical Guide (with ACO K100 Example)

What is a sloped trench drain system? It’s a modular channel drain with a built-in longitudinal slope that keeps water moving toward an outlet. In simple terms, the channel gets slightly deeper as it runs, so gravity does the work—reducing pooling and improving flow.

Why it matters: Pre-sloped channels speed up installation, control surface runoff, and help prevent standing water that can damage pavements, create slip hazards, or interrupt operations.

How a Sloped Trench Drain Works (Plain-English)

Built-in gradient: The channel series steps down in small increments, creating a continuous fall over long runs. Translation: water doesn’t linger—it heads to the outlet.

Modular sections: Channels come in numbered pieces that connect in sequence. Translation: installers follow the numbers to keep the slope correct without doing math on site.

Grates & locking: DrainLok and QuickLok® secure grates without bolts, and anti-shunt lugs stop grate rattle. Translation: fast maintenance and a quieter, tighter fit.

Example spec: ACO K100 Sloped Trench Drain System
  • 4" internal channel width with continuous built-in slope (up to ~130 ft)
  • Edge rails in galvanized or stainless steel for durability
  • Boltless grate locking (DrainLok / QuickLok®) with anti-shunt lugs
  • Grate options: mesh, slotted, perforated, ductile iron
  • Load ratings available up to Class E

Where Sloped Systems Fit Best

  • Retail & commercial aprons: Handle roof/downspout and surface sheet flow.
  • Parking decks & plazas: Low build-up depth, clean lines, ADA-friendly grates.
  • Industrial & loading bays: Higher load classes and ductile iron grate choices.
  • Streetscapes & corridors: Match architectural finishes with slotted or perforated grates.

Selection Checklist

  • Hydraulics: Length of run, contributing area, rainfall intensity.
  • Load class: Pedestrian/vehicular needs (up to Class E for heavy duty).
  • Material: Polymer concrete channel; galvanized or stainless edge rails.
  • Grate type: Mesh/slotted/perforated for look and inflow; ductile iron for heavy loads.
  • Maintenance: Choose boltless locks for quick access and reduced downtime.

Installation Tips (Step-by-Step)

  1. Plan the run: confirm outlet location, length (~up to 130 ft slope), and grate load class.
  2. Excavate trench: allow for channel depth + bedding (per manufacturer).
  3. Set channels in sequence: follow numbered pieces to maintain the slope.
  4. Connect outlets/risers: seal joints per spec; verify invert and fall.
  5. Backfill & concrete haunch: compact per guidelines; protect edges/rails.
  6. Install grates: use DrainLok/QuickLok®; check anti-shunt engagement.
  7. Punch list: water test, clean, and hand over O&M notes.

Maintenance

Schedule periodic debris removal and grate checks. Boltless locks speed access, so crews can lift, clean, and reset grates with minimal disruption.

Case Study: Dealership Apron Retrofit with Sloped Channels

Location: Midwest auto dealership • Challenge: After storms, standing water formed near service bay doors, causing slip hazards and delays.

Solution: A 180-ft run of 4" internal width sloped trench drain (comparable to ACO K100) was installed along the apron. Channels with galvanized edge rails and DrainLok grates were used for quick maintenance access. Slotted grates met both inflow and pedestrian safety targets, while select ductile iron sections were placed at turning radii with higher wheel loads.

Outcome: Surface water now clears rapidly toward the outlet during peak rainfall. Staff report easier cleaning due to boltless locks, and service operations resume sooner after storms.

Frequently Asked Questions

Is a sloped trench drain better than a neutral channel?

Use sloped when you need positive, sustained flow over distance without relying on site grading. Use neutral sections for short connections, tight elevations, or when you’re tying into existing drains at fixed inverts.

Which grate should I choose?

Pick based on load class (pedestrian to heavy vehicle), hydraulics (inflow area), and aesthetics. Mesh/slotted/perforated fit most public spaces; ductile iron suits industrial/heavy traffic.

How long can a single sloped run be?

Systems like the ACO K100 provide a continuous built-in slope for long runs (on the order of ~130 ft). For longer distances, add outlets or transition to additional runs as needed.
