Drinking Water Process Studies

Hazen and Sawyer takes a holistic approach to understanding the performance of the entire treatment system, and interrelations among different processes, in order to establish a methodology for continuous operational improvement.

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.

Hazen and Sawyer is leading a demonstration project for West Basin Municipal Water District (Los Angeles, CA) to evaluate how to integrate desalinated supply without inducing corrosion in the distribution system.

Hazen and Sawyer has taken the lead on making membrane usage more cost effective for municipal utility applications – piloting hybrid treatment systems for reuse in Miami and Nevada.

Filtration is a crucial barrier to microbial pathogens in drinking water. Hazen and Sawyer can determine the condition of your filter beds and offer you a variety of solutions to filtration issues.

The City of Lomita (CA) sought to use local groundwater to offset the demand for expensive imported water. The City retained Hazen and Sawyer to test the treatment and operation of the system to determine if it could meet water quality goals and satisfy the concerns of its consumers.

We have conducted more than a dozen corrosion control studies nationwide, including constructing custom pipe simulations to match the specifications of each particular plant.

Our research into the benefits of UV disinfection and how best to integrate it into existing water treatment systems led to the creation of the largest UV disinfection facility in the world, the ACEC National Grand Award winning Cat-Del UV Facility.

Hazen and Sawyer is developing monitoring tools for assessing and interpreting watershed-scale contaminant occurrence data, methodologies for determining appropriate target contaminants and sample sites, and pilot-testing advanced treatment options with a focus on cost efficiency.

Hazen and Sawyer recently investigated disinfection byproduct (DBP) formation during the treatment of raw Colorado River Water using aqueous chlorine and ultraviolet (UV) light advanced oxidation processes (AOPs).

With a constantly evolving regulatory environment, and population and climate fluctuations affecting supply of and demand for water, water process studies are becoming increasingly critical. Process studies yield many benefits, identifying alterations in treatment process that meet regulatory requirements while eliminating the need to construct costly new facilities. Studies can identify the need for advanced technologies, but just as often proven bench-scale testing, coupled with utilization of innovative water quality computer modeling software, identifies more simple-to-implement and cost-effective solutions.

Hazen and Sawyer has conducted bench and pilot studies, designed treatment for a wide range of source waters, and advised utilities on a variety of treatment issues, including corrosion control. We have worked for some of the largest utilities in the country, as well as for many smaller utilities. Our scientists and engineers include top researchers whose work identifies innovative treatment methods, operational tools, and water quality modeling techniques, bolstering the expertise and big-picture vision we bring to even the smallest project.

We can identify strategic alternatives to help you reliably meet current and future regulations, treat challenging ground and surface waters, prioritize infrastructure upgrades, evaluate disinfection options, and closely manage precious supply.
