HydroLogics Staff Join Hazen Water Resources Practice

Hazen and HydroLogics previously collaborated on the development of the Operations Support Tool (OST), a state-of-the-art decision support system for the New York City water supply system. This innovative tool uses near real-time data, hydrologic forecasting, and predictive modeling to guide reservoir system operations, identify future water stress conditions, and take preventive actions to maintain supply reliability, water quality, and environmental performance.

Hazen, in collaboration with Hydrologics, used the Cape Fear-Neuse combined OASIS model as a starting point for more detailed modeling of the City of Durham’s water supply system.

The Hazen/HydroLogics team worked closely with the Susquehanna River Basin Commission to expand and upgrade their existing OASIS water supply system simulation model. Upgrades were made to the consumptive use record; reservoir conservation releases and pass-by flows; the long-term hydrologic record; and operating policies.

(NEW YORK, NY - August 12, 2019) - Hazen and Sawyer has announced that Megan Rivera, Mike Sheer, Steve Nebiker, Tony Pulokas, Casey Caldwell, and Eliot Meyer - all formerly with HydroLogics - have joined the Hazen Water Resources Practice. Dr. Dan Sheer, founder and Chairman of HydroLogics and a pioneer in advancing the management of water resources through scenario planning and modeling, will serve as an exclusive Special Consultant to Hazen. Hazen has also purchased the widely used HydroLogics OASIS water supply planning software suite.

“Hazen and HydroLogics have partnered to bring cutting-edge solutions to water resources management challenges for many clients over several decades and we are excited about new opportunities to build upon this legacy,” noted Greg Gates, Hazen and Sawyer’s Water Resources Practice Lead. Notable past collaborations include the state-of-the-art Operations Support Tool for the New York City Department of Environmental Protection, planning support to the Susquehanna River Basin Commission, probability-based drought planning for the City of Durham (NC), and Water Research Foundation supported analysis of reservoir operations for climate adaptation.

The combined team offers water resources clients tremendous breadth and depth of capabilities, along with enhanced efficiency and resources that will benefit the delivery of complex projects. The new team members’ expertise in integrated planning and the operations of water resources systems complements and bolsters the wide-ranging environmental engineering and technology services for which Hazen is known. This includes scenario planning, demand forecasting, climate risk analysis, master planning, hydraulic and hydrologic analysis, and data acquisition and visualization, in addition to water infrastructure engineering and construction management services.

“We expect the transition to be seamless for existing HydroLogics clients,” said Megan Rivera, PhD, former President of HydroLogics. “Hazen’s reputation and reach as a leader in the water industry will give us the opportunity to address more of the water challenges faced throughout the world. We’re grateful for the opportunity to be a part of Hazen and look forward to continuing to deliver innovative solutions for our clients.”

“Decades of teamwork between Hazen and HydroLogics have produced strong professional ties and complementary technical strengths,” said Dr. Sheer. “I am delighted to have my colleagues move to Hazen, where they can continue our mission of improving water management. A larger pool of talented professionals can now utilize and improve OASIS to serve a wider range of clients. I look forward to this new chapter of delivering successful projects with the entire Hazen team.”
