The Hollow Water First Nation Lagoon and Sewage Treatment Plant involved the construction of a new 2,700 square foot aeration building and extensive site work to upgrade the existing lagoons. The new aeration building houses new aeration blowers, chemical storage, and injection equipment as well as the tertiary sand filtration system. The site work included decommissioning one of two existing lagoons. The second lagoon was separated into two separate aerated lagoons by constructing a new dike, raising the elevation of the existing perimeter dikes, and installing a new aeration system. Two new SAGR cells were constructed to provide secondary treatment. This project also included new roadwork, a parking lot, and a new 1.7 km lagoon discharge line to the Wanipigow River. The new aeration building and lagoon upgrades will expand the current operating capacity, bringing all-new, up-to-date equipment to better facilitate the needs of the Hollow Water First Nation community.
