New Water Treatment Plant Prioritizes Sustainability
LEED Certified Design Makes for Energy Efficient Facility
(Champaign, IL – December 7, 2009) – The Bradley Avenue Water Treatment Plant, owned and operated by Illinois-American Water, was recently LEED certified by the U.S. Green Building Council. Hazen and Sawyer provided preliminary engineering, permitting, and final design, working with River City Construction and the Illinois-American Water Company. Design/built on a fast-track schedule, the resulting 15-mgd WTP (expandable to 20 mgd) was delivering high-quality drinking water within 21 months from project commencement.
The new facility was needed to support Champaign County’s steadily-expanding consumer base and improve water system reliability. Integrating sustainable features into plant design was also a chief objective of the project. Constructed 7.5 miles outside of downtown Champaign on a “greenfield” site (a piece of previously undeveloped land), the Bradley Avenue WTP is a model of sustainability, incorporating energy-efficient technology and demonstrating close regard for the environment.
The facility is constructed of over 46% local materials, minimizing energy costs. Building materials included 39% recycled content and 69% of construction waste was diverted from the landfill and recycled locally. Other energy-conscious features include variable speed pump drives that optimize operational control; use of raw water sidestream for geothermal heating and cooling; complete recycle or reuse of waste streams to conserve water and lower raw water pumping costs; reduced “heat island” reflective roofing to minimize heat absorption; and water-efficient fixtures.
Demonstrating a holistic approach to sustainability, native plants were used for landscaping to lessen site irrigation needs, providing the dual benefits of reduced water and energy consumption. In addition, native habitat on the undeveloped portions of the site is being maintained as a local wildlife sanctuary. Stormwater runoff was minimized through the use of porous pavement, and stormwater retention areas were designed for water quality control.
Designed by Hazen and Sawyer, technical components of the facility include new raw water supply wells; treatment facilities, including lime softening clarifiers, recarbonation basins, filters, clearwells, distributive pumps, chemical feed facilities, and residuals handling facilities; standby power generation; and administrative facilities.
Thanks to its wide range of sustainable features, this highly efficient, environmentally-minded facility has achieved LEED certification. The LEED Green Building Rating System promotes and accelerates the global adoption of sustainable building and development practices, through the creation and implementation of universally-understood and accepted tools and performance criteria. The innovative Bradley Avenue plant began operation in the summer of 2009.
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.
