Well Supply and Treatment Facility Design

Facility Designed to Achieve LEED Certification

The Cocheco Well No. 1 aquifer was discovered a few years ago by a hydrogeological consultant at the north end of the city limits. Wright-Pierce carried the project through an extended pump test and water quality sampling to assess risk of problematic iron and manganese at levels requiring oxidation/filtration. Metals under stable pumping conditions for several days were steady at trace concentrations.

The new building facilities and site development are under design with the goal of achieving Leadership in Energy and Environment Design (LEED) certification. The Owner and every member of the Project Team are fully committed to producing a high quality, energy efficient, environmentally sound, high performance design.

Chemical additives at the new treatment building include disinfection, pH/Alkalinity adjustment and fluoridation. Aeration will off-gas dissolved carbon dioxide and cut chemical costs. Heat from the supply will be scavenged with geothermal mechanical equipment. Raw water transmission pipe from the well to the treatment facility has to pass under the river and is expected to be installed using the directional drill method.
