One of the most critical environmental challenges in the 21st century will be developing a sustainable water supply. By necessity and by choice, we will reuse an increasing amount of water. The technology is readily available to do so and we have the expertise to help guide utilities in making energy efficient, sustainable choices to meet their water quality and water supply challenges.
For the last three decades, we’ve helped many utilities:
- Reuse water for heating, cooling, and energy generation.
- Recharge aquifers with recycled water for indirect potable reuse (IPR).
- Reuse water for irrigation of green spaces.
As a Firm known for its superior technical abilities, we’ve worked to advance the science of reuse, developing a robust research portfolio that includes studying the most cost-effective process technologies to match water quality and treatment goals. Discovering more cost-effective process solutions will increase the viability of reuse for many utilities in areas desperate for water supply augmentation.
Hazen and Sawyer is also a leader in evaluating and developing advanced process solutions for direct potable reuse (DPR), indirect potable reuse (IPR), and non-potable water reuse. . We developed an ozone advanced oxidation process for mitigating fouling in reverse osmosis (RO) membrane applications, and UV-chlorine advanced oxidation process for removal of pharmaceuticals and other contaminants of emerging concern. From the use of membrane bioreactors (MBRs) and RO membranes to membrane alternatives such as ozone and biologically active carbon (BAC), we have the solutions for your potable and non-potable water recycling needs.
More recently, we have helped clients overcome the barriers to direct potable reuse – an inevitability as our populations swell and our water supplies shrink – through both technological advances and research into the barriers to consumer acceptance seen in some communities. While technological expertise is crucial for engineering, equally important is the ability to communicate and build consensus within communities. Hazen and Sawyer embraces both aspects of water reuse and our staff maintain positions of leadership throughout the US and around the World.
