Woodstock Inn & Brewery


When Woodstock Inn & Brewery in New Hampshire expanded to add a 30-barrel brewing system to their original 7-barrel system, the local wastewater treatment plant lacked the capacity for the increased volumes of untreated, full strength brewery wastewater.

Brewery owner Scott Rice, was facing high-strength wastewater surcharges as much as $12 per barrel, with the new sewer discharge limits requiring pre-treatment to adjust pH and reduce BOD and TSS levels to below 300 mg/L.

Location:  Woodstock, New Hampshire, USA
System Size: 6x BioGill® Towers
Average Brew Day Wasteflow Flow: 2,325 gal/day
Maximum Daily Wasteflow Flow:  5,580 gal/day


To achieve these new limits, the wastewater treatment system at Woodstock uses BioGill® technology to consume dissolved organics from the wastewater. Solids from the brewing process are side-streamed and contributed to local farms and compost operations.


Woodstock Inn & Brewery in New Hampshire uses six BioGill® Towers Plus units for the biological stage of their wastewater treatment process.


This brewery is now an example of industry-leading practices in waste stream management, contributing brewery solids to local farmers and compost operations and using BioGill® bioreactors to treat wastewater discharged to sewer to <300 mg/L BOD.
