Earth Tech Inc. has been awarded a USD$4.18 million (CAD$4.5 million) contract by the City of Toronto, Canada, for engineering design and construction verification for upgrades to the Waste Activated Sludge Thickening and Sludge Dewatering Facility at the Highland Creek Treatment Plant.

Under the four-year contract, Earth Tech will provide the preliminary engineering design, detailed design and construction contract administration, as well as post-construction monitoring and reporting. The project components include upgrades to the sludge thickening facility, installation of new dewatering centrifuges, relocating of the ferrous chloride facility, and consolidation of all permits into a single, site-wide Certificate of Approval for air and noise.

“This contract represents Earth Tech’s first major assignment at the facility since the recently completed process control upgrades and implementation of a new digester facility,” said Robert Johnston, Vice President of Earth Tech’s Canada East operations. “The contract also allows us to maintain our position as the plant’s engineer of record, a title we have held since the facility’s inception.”
