ACO Linear Drain System: Complete Guide for Outdoor Drainage

The ACO Linear Drain System is a modular trench drain solution engineered for efficient stormwater management. Designed with a 4-inch internal width, it integrates seamlessly into residential, commercial, and public landscapes. Whether on plazas, patios, or busy driveways, this system ensures reliable water control without compromising appearance.

Why Choose the ACO Linear Drain System?

Continuous drainage: Unlike point drains, ACO trench systems capture water along their full length, minimizing pooling and surface damage.

Discreet design: The 4-inch width allows the drain to blend into surfaces while still handling heavy rainfall.

Long-run capability: Continuous slope installations up to 130 feet provide reliable drainage for even large projects.

Key Features

• Simple installation: DrainLok® and QuickLok® systems enable fast grate removal and reinstallation.
• Precision fit: Anti-shunt lugs and numbered channels ensure correct alignment and long-term performance.
• Grate selection: Choose from slotted, perforated, mesh, or ductile iron grates rated up to Class E.
• Durability: Available with galvanized or stainless steel edge rails for strength and corrosion resistance.

Applications

• Driveways & garages: Prevent water intrusion and surface wear at vehicle entry points.
• Patios & pool decks: Keep surfaces dry and safe for family or guests.
• Commercial walkways & plazas: Enhance safety and reduce maintenance in high-traffic zones.
• Public facilities: Perfect for schools, parks, and community centers needing long-lasting drainage solutions.

Installation Overview

1. Excavate the trench with space for bedding and encasement.
2. Set slope grade for optimal runoff toward the outlet.
3. Install numbered channels sequentially for precision.
4. Backfill with concrete, keeping grates in during pour.
5. Connect to stormwater outlet and seal as required.

Case Study: Chicago Public Plaza

Location: Downtown Chicago plaza • Problem: Frequent ponding created safety issues for pedestrians and damaged paver joints.

Solution: A 4" ACO Linear Drain System with stainless steel edge rails and perforated grates. The installation covered a 95-ft stretch with a 0.5% continuous slope, tying into existing storm infrastructure.

• Install time: 2 days with minimal disruption.
• Result: Ponding eliminated; surfaces dried faster after rainfall.
• Design impact: Drain blended seamlessly into modern stonework.

Frequently Asked Questions

Which grate style is best?

Use perforated or slotted grates for walkways, and ductile iron for areas with heavy vehicles.

What is the maintenance schedule?

Quarterly inspections are recommended. Thanks to DrainLok®/QuickLok®, cleaning is tool-free.

How long does stainless steel last?

Stainless rails are highly resistant to corrosion, making them ideal for high-moisture or salted environments.
