Drinking Water Research and Innovation

Long a leader in helping clients achieve cost-effective regulatory compliance, we have recently developed tools to help utilities most strategically comply with the Stage 2 D/DBP Rule.

The presence of endocrine disrupting compounds and pharmaceuticals and personal care products has been recognized in water for more than 40 years. We’re working with leading research foundations to give rational context to occurrence data, identify proper target compounds, and develop treatment solutions.

The City of Glendale (California) is leading the industry in identifying and testing hexavalent chromium treatment technologies for drinking water. Hazen and Sawyer is the Technical Lead and Co-Principal Investigator on studies of ion exchange (weak and strong-base), adsorptive media, and reduction/coagulation/filtration with microfiltration.

One of the most versatile, yet energy intensive, barriers against chemical contaminants is advanced oxidation processes. We’re investigating the benefits and limitations of several AOPs using pilot scale installations.

Hazen and Sawyer is currently leading world-class teams in exploring climate change impacts on drinking water utilities such as long-term demand forecasting, reservoir operations, and extreme weather events.

Hazen and Sawyer has taken the lead on advancing novel process designs to make membrane usage more cost effective for municipal utility applications – piloting hybrid treatment systems for reuse in Miami and Nevada.

By studying the effects of subtle water quality changes and investigating the use of new corrosion inhibiting compounds, we’ve been able to provide informed recommendations with regard to lead and copper corrosion and water quality/treatment changes that may be needed to comply with new regulations, reduce potential capital and operating expenses, and protect public health.

We've led the industry in developing a better understanding of the benefits of UV disinfection, how best to integrate it into existing water treatment systems and increasing the knowledge base on the approach for proving the effectiveness of UV disinfection equipment through innovative validation testing procedures.

As worldwide populations continue to rise and clean water sources become more stressed from both increased freshwater withdrawals and treated wastewater discharges, providers find themselves faced with limited sources of high-quality water to meet the myriad needs of society.

Since our founding, Hazen and Sawyer has advanced the limits of technology to meet the needs of providers and protect the public health. We’ve designed the largest DAF and UV disinfection facilities anywhere in the world, hundreds of plants ranging from 0.5 mgd to 20 mgd, and today we’re researching the drinking water solutions of tomorrow.

Whether it’s facing the growing challenge of endocrine disrupting compounds and pharmaceuticals/personal care products in our water supply, controlling corrosion and disinfection by-products in a distribution system, making the most efficient use of membranes, or assessing and managing the risks of climate change and extreme weather events, Hazen and Sawyer’s leading experts are working with top research foundations and some of the world’s largest utilities to find the most effective and efficient solutions.
