PURE WATER BREW ISN’T A CORPORATE PROMOTION OR A SAMPLE OF A NEW PRODUCT—IT’S A DEMONSTRATION OF WATER PURIFICATION TECHNOLOGY THAT COULD HELP SOLVE WATER SHORTAGES.

Let’s be clear—the water used to create Pure Water Brew was once sewage. Like all water we drink, it was once consumed by humans, treated to remove contaminants and then returned into the environment. This particular water was cleaned at Clean Water Services’ treatment plant and then run through a high purity water system.

The high purity water system purifies the water with proven technologies, including reverse osmosis with 0.0005 micron membrane pores—the same purification technique used by premium bottled water companies. The final product meets or beats drinking water standards, making it a truly blank slate for brewers to begin their creations.


1. DURHAM WATER resource recovery facility

Water leaving this facility in Tigard, Oregon, is cleaned to some of the highest standards in the nation and returned to the Tualatin River or used to irrigate local golf courses, athletic fields and parks. That’s business as usual for Clean Water Services, 60 million gallons a day. For the small quantities of water produced for Pure Water Brew, the following extra steps have been added:

2. Ultrafiltration

Membranes remove bacteria, protozoa and some trace pathogens. This treatment is used by premium water bottling companies.

3. Reverse Osmosis

Membranes remove salt, organics, trace pollutants and remaining pathogens. This treatment, too, is used by premium water bottling companies.

4. Disinfection/Advanced Oxidation

Oxidants and UV light kill pathogens and destroy trace pollutants.

5. testing and Approval

After rigorous, third-party testing, authorities approve high purity water for human consumption.

6. Delivery

High purity water delivered to brewers.

7. Oregon Brew Crew
