Xylem Technology to be Used in PureWater Colorado Direct Potable Reuse Demonstration Project

Xylem has been engaged as a water technology solutions provider to the PureWater Colorado Demonstration Project, which aims to demonstrate direct potable reuse (DPR) as a safe, reliable and sustainable drinking water source.

Denver Water has partnered with Carollo Engineers, WateReuse Colorado (WRCO) and Xylem on the project which is located at the Denver Water Recycling Plant and will run during April this year. Some of the water produced will be used to brew beer to raise awareness among the general public about this water purification process.

Water reuse is part of Colorado’s Water Plan to reduce the amount of water diverted from rivers and streams, creating a sustainable, efficient way to extend the state’s water supplies.

Steve Green, Business Development Manager, Xylem said, “We are very excited to be part of this forward-looking, important project that aims to promote a sustainable, reliable and safe drinking water treatment process. It is crucial that we implement sustainable solutions, like water reuse, to meet future water needs. We hope that this demonstration will help to raise awareness and understanding among the local population and community leaders about how DPR can help to provide for their water needs now and in the future.”

A range of Xylem’s solutions including a Wedeco MiPRO advanced oxidation process (AOP) pilot system and a Leopold granulated activated carbon (GAC) filter pilot will be used in the project which features a unique treatment train that avoids the use of reverse-osmosis (RO) membranes and their associated high capital and operating costs as well as brine disposal.

John Rehring, Vice President, Carollo Engineers said, “As national leaders in water reuse, we were happy to partner with Xylem to demonstrate the use of advanced technologies - an extension of our efforts to develop a regulatory framework, and public outreach activities specific to Colorado.”

Xylem is a frontrunner in the field of water reuse technology, providing advanced solutions and expertise to reuse applications across the US, as well as globally. In California for example, Xylem’s Wedeco MiPRO advanced oxidation processes (AOP) is operating at Los Angeles Sanitation’s Terminal Island Water Reclamation Plant. The customized solution is the first greenfield AOP design using ultraviolet light with chlorine – a significant innovation to make water reuse more sustainable and cost-effective.

Last year Xylem signed a multi-year commitment (2017-2019) to support Water Environment Research Foundation (WE&RF) research into water reuse, building on a previous three-year research partnership and solidifying Xylem’s commitment to advancing the use of recycled water. Internationally, Xylem works together with the IVL Swedish Environmental Research Institute and the Singapore Public Utilities Board (PUB) to progress water reuse.
