Hazen and Sawyer Joins Chevron Energy Solutions to Implement Energy Conservation Projects at Utility
Hazen and Sawyer, in association with Chevron Energy Solutions (CES), has recently been selected to provide Design-Build Services for the evaluation and implementation of Energy Conservation Methods (ECM) for Broward County Water and Wastewater Services.
Under this contract, Hazen and Sawyer, in tandem with CES, will evaluate potential ECM projects, estimating their construction costs and payback (self-funding) periods based on the savings that would be realized from the various energy conservation improvements. To be considered economically attractive by Broward County, payback periods should not exceed 20 years. Sample ECM projects include:
- Conversion of existing surface aerator treatment basins to fine bubble diffusion, reducing power consumption in the aeration process.
- Segregation of Fats, Oil and Grease (FOG) at the Broward County Septage Receiving Facility, reducing organic loading to the plant, along with direct discharge of FOG to the NRWWTP anaerobic digester process.
- Collection and scrubbing of anaerobic digester gas for reuse in generating power, coupled with implementation of a dual-fuel electric generator facility.
The results of our ECM evaluation efforts will be compiled into a Comprehensive Energy Audit (CEA) Report for review with Broward County Water and Wastewater Services. Selected ECMs will then be implemented via a design-build procurement approach. Hazen and Sawyer, working in concert with CES, will prepare conceptual plans and specifications as necessary to solicit fixed cost bids from construction contractors. Projects will be constructed and energy savings will be monitored, with CES providing an Energy Guarantee to Broward County accordingly.
Incorporated in 1915, today Broward County is home to approximately 1.8 million residents. Located on the southeast coast of Florida, the County consists of 31 cities including Fort Lauderdale. The Water and Wastewater Services Department provides service to over 57,000 water customers, 42,000 wastewater customers, and 3,000 reclaimed water customers. Hazen and Sawyer has worked with the County for more than two decades, most recently providing design and construction management services for the expansion of the North Regional Wastewater Treatment Plant to 100 mgd.
Since our founding in 1951, Hazen and Sawyer has focused on two things: providing safe drinking water and controlling water pollution. Our range of services encompasses the planning, design, and construction management of water and wastewater-related projects – from clean water treatment, storage, and distribution to wastewater and stormwater collection, treatment, and reuse.
