Earth Tech Ireland (www.earthtech.com), a business unit of Tyco International Ltd. (www.tyco.com) and global provider of consulting, engineering, and construction services, has been awarded two contracts to upgrade water and wastewater treatment plants in Ireland.

Dublin City Council signed a $22.3 million (€16.5 million) contract with Earth Tech Ireland to refurbish Ireland’s largest drinking water facility, the Ballymore Eustace Water Treatment Plant in Kildare. Earth Tech will design and build new filtration, sedimentation, chemical, and sludge facilities in an effort to help maintain the plant’s current technical, environmental, and safety standards while upgrading the facility’s capacity. The project, which provides the core of Dublin’s water supply, is intended to increase the water treatment plant’s capacity from 70 million gallons per day (265 million liters per day) to its peak capability — 88 mgd (333 Ml/d). The refurbishment project is expected to take four-and-a-half years to complete.

The second agreement is a $28.7 million (€21.3 million) design-build-operate project awarded to Earth Tech by the Laois County Council. Earth Tech, with its partner Bowen Construction, will design and build upgrades to the Portlaoise Main Drainage Scheme, which includes a wastewater treatment plant and collection system. Specifically, Earth Tech will provide process design, mechanical, and electrical contracting services for the two-year project, which includes new inlet pumping, aeration, sedimentation, tertiary filtration, and sludge dewatering and drying units for the 39,000 population equivalent sewage treatment plant. The Earth Tech team will also operate the facility for 20 years once it has been commissioned.
