The Wastewater Services Division of the Planning & Public Works Department operates and maintains one Sewage Treatment Plant, 13 Sewage Lift Stations and approximately 86km of gravity sewers and force mains, including associated manholes.
The wastewater treatment facility is one of the largest infrastructure projects the Town has ever taken on. Located north of the Town of Gander and south of Whitman's Pond, the wastewater treatment plant is a replacement for the pre-existing wastewater treatment facilities on Magee Road and Old Navy Road.
In 2017, the Town of Gander allocated funds for the construction of a new wastewater treatment plant to meet the updated Canadian environmental effluent water-quality requirements. The contract was awarded in 2018, and Pomerleau Inc completed the design-build process. Currently operational, the plant features an aerated lagoon and is specifically designed to cater to Gander's growing population, which is estimated to reach 17,500 by 2040. The facility incorporates preliminary, primary, and secondary levels of treatment, along with effluent disinfection measures, aimed at reducing the impact of effluent discharge on the receiving water. The treatment system includes a manufactured water body with artificial aeration, facilitating the biological oxidation of wastewater
The facility has greatly increased the performance and capacity of Gander's wastewater treatment system ensuring that the municipality meets Federal Wastewater Systems Effluent Regulations as the Town continues to grow.
