The Nashville Metropolitan Government West Park Equalization Facility recently earned the Envision Platinum award for sustainable infrastructure, the highest rating of the Envision system. This is the first joint wastewater and park project in the U.S. to receive an ISI Envision rating award and the tenth project in North America to receive recognition.

Hazen and Sawyer’s design at the Venice Island CSO Facility incorporated the use of many “green” features, including a “living” roof system; rain gardens; a glass stair tower to reduce the need for interior lighting; photo and occupancy sensors for energy efficiency; shade and reflection devices to reduce the need for air conditioning; and water-conserving plumbing fixtures.

The LEED certified Bradley Avenue Water Treatment Plant in Champaign County, Illinois, is a model of sustainability, incorporating energy-efficient technology and demonstrating close regard for the environment.

The urban Jones Creek Hammock Restoration project reduces sediment and other pollutant loadings to the Loxahatchee River Aquatic Preserve, while providing passive recreation and environmental education in a beautiful wetland.

Hazen and Sawyer designed and operated the first indirect potable reuse project in the country that focused on surface water discharge and infiltration, as part of a regional South Florida effort to develop sustainable water supplies.

The South Collier Regional Water Treatment Plant treats up to 20 mgd of brackish groundwater from the Hawthorn Aquifer to sustainably supply a growing population.

Hazen and Sawyer has practiced sustainability since 1951 by delivering the most energy-efficient and environmentally-friendly designs to meet our clients’ water infrastructure needs. Our history demonstrates our capability of leveraging sustainable innovations including energy and resource recovery, water reuse, and green infrastructure. We understand that capitalizing on these types of individual opportunities provides a mutual benefit to the environment and the utility’s bottom line. Our experience with discrete tools, such as life-cycle assessment and carbon footprinting, also provides a quantitative means for benchmarking design, operation, and technology strategies to provide robust decision-making capabilities. Infrastructure resiliency, a new challenge to our industry, also permeates our design processes to enhance safety and reliability of our critical water infrastructure.

The developing paradigm of sustainability has shown us that the whole is truly greater than the sum of its parts. Addressing the extents of sustainability, or the triple bottom line, ensures that we decouple our decision making purely from direct project costs, and begin to consider the social, environmental, and economic impacts of project alternatives. Our pragmatic approach to these considerations assist our clients in meeting their sustainability goals, and demonstrate the value of these measures to the communities they serve.

At Hazen and Sawyer, the key to implementing sustainable solutions is evaluating and designing with efficient and reliable technologies, with a focus on the financial incentives that often subsidize the most sustainable solutions for design. Using these principles, Hazen and Sawyer is committed to designing facilities that are environmentally-friendly, energy-efficient, sustainable, and safe. We also “walk the talk” within our own walls by championing sustainable practices such as leveraging technology to minimize our resource consumption, reducing our carbon footprint by minimizing energy use, and removing bottled water from our offices by drinking the high quality tap water produced by our clients.

As a pioneer in environmental engineering, we know that facilities perform at their greatest level when they imitate nature. We stay at the forefront of green and sustainable architectural design, planning and developing projects in a manner that minimizes impacts on natural resources. Use of sustainability rating systems, such as Envision and LEED, allow us to readily identify and incorporate comprehensive sustainability measures into our designs. Our award-winning capability of leveraging these sustainability rating systems for the planning, design, and operation of water infrastructure projects highlights our fundamental grasp and embrace of the principles of sustainability.
