The county expects the work to be completed in the fall and expect no interruptions to wastewater services during that time, however, residents may be concerned about possible odour during the upgrade.
OXFORD COUNTY - One of the lagoon cells at the Tavistock Wastewater Treatment will be getting an upgrade in the future.
The upgrades are needed as the lagoon has been in operation for 20 years.
The work will help to remove the build up of biosolids and sludge as well upgrades to the aerators that treat sewage and help keep odour under control.
The initiative will see repair work along the banks of the lagoon, to fix some of the erosion that has taken place. The county says residents may be concerned about possible odour during the upgrade.
Odour from the Tavistock WWTP was more noticeable in May and June partly due to water levels which were deliberately lowered for construction work. When the water levels are lowered, the biosolids and sewage are exposed, releasing strong odours.
The county did pause construction largely in part because of the complaints, at which time the lagoon levels were restored. Typically it takes three to five weeks for the natural microbial biological action to return to normal.
The county expects the work to be completed in the fall and expect no interruptions to wastewater services during that time.
