Manufacturing plants typically require trench drains, grated floor drains, heavy duty point drains, and chemical resistant drains. The specific drain type depends on the volume of wastewater, the presence of oils or chemicals, and safety or sanitation requirements in the facility.
Why Industrial Drains Matter in Manufacturing Facilities
Manufacturing floors handle heavy traffic, machinery runoff, oils, chemicals, and washdown water. The Ontario Building Code (OBC) and municipal Sewer Use Bylaws require drains that safely handle flow, contaminants, and load stress.
1. Trench Drains
Trench drains run along production lines or work zones.
They are ideal for:
- Large surface washdowns
- Machinery coolant runoff
- High traffic forklift areas
- Wide coverage drainage
Trench drains prevent pooling and help maintain safe walking surfaces.
2. Heavy Duty Point Drains
Point drains collect water from a single low point.
Manufacturing plants use them near:
- Machine bases
- Loading docks
- Cleaning stations
- Maintenance areas
They rely on correct slope and stable grates to handle high impact.
3. Grated Floor Drains
Common in assembly areas, food processing plants, and warehouses.
They are designed to:
- Capture debris
- Allow quick cleaning
- Support heavy equipment
- Prevent slipping hazards
Stainless steel grates are preferred for durability.
4. Chemical Resistant Drains
Industries handling acids, solvents, or corrosive fluids need drains made from:
- Polypropylene
- PVC
- High density polyethylene
- Epoxy coated cast iron
These drains withstand aggressive wastewater that would damage standard metal drains.
5. Oil and Grease Drains with Interceptors
Facilities using lubricants, fuels, or hydraulic fluids often need drains connected to:
- Oil interceptors
- Grit traps
- Separator tanks
This prevents contaminants from entering municipal systems and avoids fines under local sewer bylaws.
(Reference: Toronto Sewer Use Bylaw Chapter 681; Peel By-law 53-2019)
6. Sanitary Drains for Food Grade Facilities
Food processing plants require drains that meet hygiene standards.
Common features include:
- Stainless steel channels
- Smooth internal walls
- Easy to clean designs
- Built in sediment baskets
These drains reduce contamination risks and support HACCP compliance.
Final Note
Choosing the right floor drains keeps production areas safe, compliant, and free of water hazards.
