H: What made you realize it was time for a change in regard to how we manage water filtration at our headquarters?
B: Well, we changed filtration here because we started working with WateRx in New York. We were looking for a better option to recommend for our customers (cafes), and a great coffee shop called REX told us about these WateRX. All the units are really customizable so the water qualities can be exactly as you want them to be. The three units we have here are made so that we can change the makeup of the filters internally and thus the taste of the water pretty easily.
H: What can you tell us about WateRx and why did you decide to use them?
B: WaterRx is a company based out of Cincinnati, Ohio, and they are a national water filtration brand. We decided to go with them because the filters are super reliable, they need very little service and upkeep and they last significantly longer than any other filters we’ve used in the past. This ties into the green aspect of the filter—the medium, meaning the filtration material, is all natural minerals and rocks. Once you need a filter change you can dump it outside with no issue and no disturbance to the natural environment. We were really sold when we realized how durable the filtration is and it’s unique ability to process large volumes of water—the filters never break!
H: Can you give us a breakdown of how the filtration works?
B: First, water enters through the top of the unit and then there are three layers of medium (made up of rocks, sand, salt, and resin) that remove unwanted items from the water. Unwanted items include bacteria, rust, dirt, chlorine, arsenic, mercury, odor, and color.
H: What is the key takeaway for people who don’t know much of anything about water, water filtration, and its impact on coffee and the environment?
B: Number one would be that properly filtered water makes your coffee taste better. Second and equally important is that adequately filtered water makes your machines last longer. Sustainably speaking, the tanks we are using now only have to be recharged 50,000 gallons, or every 12-18 months, and can be reused. Our previous filters only lasted 3-6 months and had to be thrown away.
H: What does “adequately filtered water” mean exactly?
B: The simple answer is that it is water that is free of chlorides, arsenic and anything harmful. The water also has a balanced hardness. We have used the set of parameters that La Marzocco recommends for our water.
H: What else do you want us to know about the filters?
B: The big filter that we use in the coffee and tech departments track the amount of water used. The tracking means that you can check on averages used and you can decide if you need to reduce your usage and it allows you to know your carbon impact. Also, this makes it easier to know when you need to “recharge” the system, meaning, swap out the old filtration material.
H: Who currently uses this filtration?
B: A handful of our accounts are already implementing the new filtration: Open City in Washington DC, OK Café in Astoria, NY, Brunswick in Brooklyn, and Big Bear in Washington DC. In terms of our training centers they are in place in NY, Atlanta, Washington DC, and Durham and we are recommending the filtration for all new accounts in those areas.
H: What’s next in the world of water filtration?
B: We will continue to develop our water parameters so that we can make the water taste as delicious as possible for our coffees. As we calibrate we will move this filtration into all of our TCs. WateRx is a great partner to continue to work with!
