Brewery floors slope toward drainage systems to prevent standing water during the brewing and bottling processes. The slight grade, about ¼" per foot, is subtle but can complicate the concrete pour.
Trench drains simplify a brewery’s concrete floor, one of the earliest stages in any brewery buildout.
Where you’ll find brewery drains:
- On the brewhouse floor
- Along the aisles between fermenters
- Inside the walk-in cooler
- In the bottling/packaging area
Water usage depends on the size of brewery and generally is 2 to 5 times the amount of beer produced. At minimum, install a 4" trench drain system for your brewhouse floor. The trench drain should be pre-sloped for quicker drainage and offer a catch basin to catch solids before the effluent reaches the plumbing.
Polymer Concrete Brewery Drainage Chart
Temperatures in portions of the process are high and limit the use of plastic bodied drainage systems. In high temperatures with chemicals, brewers should use stainless steel or polymer concrete trench drains. Still, in those portions of the process that see cooler temperature with chemicals, a plastic bodied drain may be appropriate.
- Does my application require a greater flow volume that a standard 4" wide drain?
- What load will the grating and drain experience? Pedestrian or Fork truck?
- What temperature requirements will this drain need?
- How corrosive are the solutions I’m putting in the drain?
- What aesthetic, if any, are we trying to convey?
- Design your trench drain to handle pallet jacks – because it’ll happen someday, whether you planned for it or not.
Recommendations for Brewery Drainage Systems
SS600 Stainless Steel Drain
by Trench Drain Systems
Polycast 600/700 (by Hubbell)
Polymer or Vinyl Ester Concrete
Polycast polymer or Vinyl Ester concrete systems with stainless steel edging and grates are a good alternative to stainless steel channel bodies. Polymer channels are chemically inert and resistant to high temperatures. Polycast systems can meet any brewery demand.
The Polycast 700 Series is a durable drainage system with polymer concrete channel bodies and 4" channel interior. Polycast 700 Series is not prone to shifting after installation and offers a selection of accessories to make cleanouts more accessible. The system’s frame and cast iron or ductile iron grate reinforce the system to Class D or E load rating.
Pro-Plus 100 Series (by MEA-Josam)
MEA’s Pro-Plus series featured a glass-fiber reinforced polyester (GRP) and sheet molding compound (SMC) capable of handling 210F heat without warping. Each Pro-Plus system offers standard, bottom or side outlets for adaptable designs to suit your brewery layout.
Diverse grating options include STARFIX iron, stainless and plastic clip-in grates. STARFIX grates eliminate traditional locking devices, leaving more room for effluent flow without sacrificing load rating. Pro-Plus grates reinforce the system up to pallet jack and forklift traffic.
