ACO Drain System – K100 (39.37″ Channel) Guide: Sizing, Grates, and Installation

The ACO K100 is a modular trench drain with a 4-inch internal width and a 39.37″ (1-meter) channel length, engineered for dependable surface water management in commercial and residential settings. This guide explains how it works, how to select grates and slopes, and how to install it cleanly for a professional finish.

What Is the ACO K100—and When Should You Use It?

Definition (plain-English): A linear trench drain collects surface runoff along a line and moves it to a safe discharge point. The K100 uses 1-meter (39.37″) channels that connect end-to-end to make longer runs. This creates a continuous intake slot—ideal where puddles or sheet flow build up.

When it’s the right choice:

  • Driveways, loading areas, and sidewalks where a curb inlet is impractical.
  • Parking lots & garages that need continuous capture along traffic aisles.
  • Courtyards & patios requiring a clean architectural look.

Key Features (Explained)

  • Boltless locking (DrainLok® & QuickLok®): Tool-free grate removal for fast cleaning—no loose bolts to rust or strip.
  • Anti-shunt lugs: Stops that prevent the grate from sliding sideways under wheel loads.
  • Numbered channels: Labels keep slopes and flow direction aligned during installation.
  • Grate options up to Class E: From pedestrian-safe mesh/slotted/perforated stainless to ductile iron for heavy-duty traffic.

Grate Selection & Load Classes

Load Class basics: Grates are tested for strength under load. Higher class = heavier traffic. Class A–C is typical for walkways and light vehicles, Class D handles occasional trucks, and Class E tackles heavy-duty areas like service lanes. Choose the lowest class that safely covers your heaviest expected load to control costs.

Finish & appearance: Stainless and powder-coated grates give a refined look for high-visibility areas; ductile iron is the workhorse for industrial sites. Mesh or slotted patterns balance intake area with heel safety and debris resistance.

Quick tip: If you plow snow or expect gravel, pick a grate pattern with openings large enough to avoid frequent clogging, and plan for easy seasonal lift-offs via the boltless locking.

Edge Rails: Galvanized vs. Stainless

  • Galvanized steel: Cost-effective corrosion protection for most outdoor installs.
  • Stainless steel: Best for coastal, foodservice, or architectural applications where appearance and corrosion resistance matter.

How to Plan Slope & Layout (Step-by-Step)

  1. Map runoff paths: Identify high points and where water currently ponds.
  2. Pick discharge point(s): Catch basin, underground pipe, or daylight outfall.
  3. Choose run length: K100 channels are 39.37″ each—count channels to cover the distance.
  4. Set slope: The system supports continuous slope up to 130 ft. Target ~0.5–1% where possible for faster self-cleansing flow.
  5. Confirm grate class: Match to traffic (see Load Classes above).
  6. Plan joints & end caps: Use numbered channels to keep the fall consistent.

Installation Overview

  • Excavate trench (allow for bedding and concrete haunching per manufacturer guidance).
  • Set a string line to your target invert elevations.
  • Place channels in sequence (follow the numbers) and connect.
  • Secure and pour concrete backfill/haunch. Protect tops during cure.
  • Install grates using DrainLok® or QuickLok®—no bolts required.
Maintenance: Lift grates tool-free, remove debris, and flush the channel. The boltless locking dramatically shortens cleanout time.

Case Study: Parking Garage Retrofit with K100 (120-ft Run)

Site: Two-level municipal parking garage with chronic ponding at the ramp transition.

Challenge (plain-English): Wide sheet flow collected at the ramp bottom, causing puddles, slip hazards, and nuisance icing in winter.

Solution

  • Installed a 120-ft K100 run using numbered, sloped channels to a central outlet.
  • Selected ductile iron grates (Load Class E) for occasional truck traffic.
  • Used QuickLok® for fast, bolt-free access—important for monthly cleanouts.

Results

  • Eliminated standing water at the ramp after storm events.
  • Cut maintenance time for grate lift-and-clean by removing corroded-bolt issues.
  • Improved safety—no slip complaints recorded in the three months post-retrofit.

Before You Order

  • Measure run length and count channels (add 5–10% for cuts and contingencies).
  • Verify traffic type to pick the correct load class.
  • Confirm discharge type (end outlet, bottom outlet, or catch basin).

FAQs

Can I use K100 along a residential driveway?

Yes. Choose a pedestrian/light-vehicle grate (Class B–C) and ensure proper slope to the discharge point.

How often should I clean the channel?

Check seasonally and after major storms. The boltless locking makes grate removal quick, so maintenance is simple.

When should I choose stainless edge rails?

Use stainless in coastal zones, foodservice areas, or premium architectural spaces where corrosion resistance and appearance are top priorities.
