Earth Day: Closed-Loop Brewing System

  • April 22nd, 2017

Earth day was first celebrated on April 22, 1970. It is a date that is used to raise awareness and demonstrate support for environmental protection. That being said, this date is significant to Cowbell because we support protecting the environment. Cowbell will have the first “Closed-Loop Brewing System” in the world. The system will supply fresh Ontario well water to our facility and in return we will treat all effluent wastewater and release it back into the groundwater table on the property. The closed-loop brewing system will have no connection whatsoever to the municipal water supply or sanitary sewer systems.

What is Cowbell’s Closed-Loop Brewing System?

Cowbell will source 100% of all brewing related water from an onsite aquifer. The onsite well will supply all brewing related needs -brewing liquor, CIP, transfers and packaging.

Cowbell will treat all incoming water through the use of particle and carbon filters and UV sterilizers to remove water impurities.

The brewing process will use water in four main areas; brewhouse, cellar, packaging and utilities. The process of brewing beer involves using a lot more water than what is actually contained in the beer itself. Beer is 90-95% water but typically for every 1 L of beer produced there can be upwards of 10 L of water that will be used and sent down the drain. Cowbell’s goal is to minimize water use in the brewing process by eventually achieving a 4:1 water to beer ratio. Every batch of delicious Cowbell beer brewed can produce up to 50 hL (5,000 L) of beer and in return will strive to use only 200 hL of water throughout the process.

Cowbell’s wastewater collection system will involve three sanitary sewer outlets that will collect all sewage, kitchen and brewing effluent that will all lead into the main wastewater line leading into the onsite wastewater treatment system.

Cowbell’s wastewater treatment system will consist of a series of seven large underground tanks that will treat all effluent before being released into the onsite wastewater bed. The system will be monitored from an onsite control/blower building that will hold all dosing stations and pumping equipment.

Cowbell will release all treated water through three force mains that will lead into a series of underground perforated piping which will then slowly infiltrate through sand and back into the groundwater table. The bed will consist of six cells, each with nine runs of parallel perforated pipes that are 28 m long. This covers approximately 1,512 m in total length and an area of 7,590 m2.

Happy Earth Day!
