Brewery drain systems

Drains that are easy to clean and sanitary. Brewery floor drains are set in concrete — a permanent part of your infrastructure — so install them with durability in mind.

Do it right, do it once.

Your vision is about to come to life. Choosing the "do it right, do it once" strategy highlights the importance of your brewery's foundations: the slab and drainage should last the life of the building. Then you can change what's around the floor without long downtimes — that's where premium stainless drains prove their value.

How to design and install a drain system for a brewery

Breweries handle a lot of water and liquid waste. An efficient drainage system prevents contamination, maintains hygiene, reduces the risk of accidents and keeps you compliant. A step-by-step guide:

1. Assess brewery layout and flow

Map your fermentation tanks, brewhouse, packaging area, cold storage, cleaning stations (CIP) and wastewater collection points. Goal: identify where water, beer or chemicals are discharged most often.

Distillery or winery too? Our beverage production guide covers tank dumps, sewer limits and when 316 makes sense.

2. Understand liquid types and volumes

Rinse water, alkaline and acidic cleaning solutions, spent yeast and sludge, waste beer or wort. Estimate peak volumes during cleaning and brewing.

3. Choose the right drain types

4. Material selection

Brewery drains must withstand corrosive chemicals, heat and pressure washing. Choose stainless steel 304 or 316 — highly corrosion resistant, durable and easy to sanitize — and PVC or HDPE for buried piping.

5. Drainage design best practices

  • Sloped floors: 1–2% slope toward the drains for complete runoff.
  • Drain spacing: no more than 12–15 feet apart in heavy use areas.
  • Odor traps: install P-traps to prevent foul odors.
  • Backflow prevention: especially when connecting to municipal lines.
  • Cleanouts: regularly spaced access points for maintenance.

6. Grease and solids interceptors

Install screens or interceptors to catch solids and prevent clogging — especially near mash tuns and grain handling.

7. Ventilation and safety

Vent drains to prevent pressure buildup, and use non-slip grates and covers on all trench and floor drains.

8. Installation steps

  1. Mark locations for all drains.
  2. Cut concrete or trench as needed.
  3. Slope the floor toward drains (1/8"–1/4" per foot).
  4. Install drains and connect to main drainage lines.
  5. Seal joints to prevent leaks.
  6. Test with water before backfilling and pouring concrete.
  7. Install grates and covers once flooring is complete.

9. Local codes and environmental considerations

Check local plumbing and wastewater codes: discharge permits, pre-treatment requirements and disposal of yeast, hops and chemicals.

10. Maintenance plan

Design for easy cleaning and schedule regular inspections, jetting/flushing and interceptor emptying.

Common pitfalls to avoid: inadequate slope (pooling), cheap materials (corrosion and failure), ignoring chemical compatibility, and not planning for future expansion.
