Oxford County is upgrading one of the lagoon cells at the Tavistock Wastewater Treatment Plant (WWTP). Regular maintenance is needed to ensure the lagoon system is operating efficiently and protects the local ecosystem.

What we’ve done since our last update

In response to community feedback about odour, we paused construction in the spring to look for additional measures we could take to address this concern.

  • We temporarily returned Cell 1 to its normal operating capacity to manage odours to the degree possible. We used Bioxide (calcium nitrate) and hydrogen peroxide to more quickly restore the natural microbial biological action that is needed in the lagoon cell to most effectively break down sewage.
  • In July, we expanded our odour control system to include a new vapour pipeline system along the lagoon property line that blows a dry mist odour neutralizer through pipelines and into the air to bind with odourous materials. This expanded system is intended to provide a more effective and longer lasting odor neutralizer that can cover a wider area around the lagoon cells.
  • All sewage flows to the Tavistock WWTP are now being diverted into Cell 2. We have relocated surface aerators from Lagoon Cell 1 to Cell 2 to boost performance of this cell to prepare to restart construction on Cell 1. We’ve also set up an automated dosing system for Bioxide for Cell 2 to enhance its biological performance (and odour management capacity) during peak times.
  • We have left extra aeration time for sewage to break down in Lagoon Cell 1 before resuming construction.

Managing odour as we restart construction

Later this month, we will begin transferring treated sewage in Lagoon Cell 1 into Lagoon Cell 2. Once Cell 1 is emptied, active work can then begin to dry and remove the remaining biosolids over the latter part of the summer and early fall. The biosolids will need some time to naturally dry out and odours can be present when biosolids are first exposed to air.

In addition to the expanded vapour pipeline system, we are using chemical treatment enhancers to boost operational performance of the lagoon (Bioxide additions to Cell 2) to manage odour to the degree possible. We have also made preparations to apply thickening agents or other materials directly to the biosolids to help speed up the drying process as appropriate. We are also exploring other processes for removing biosolids that may allow a shorter drying time so that we can move them offsite sooner.

Moving forward

Oxford County is committed to the health and safety of residents and the environment. As we have explained, all operational practices during construction were reviewed by the Ministry of the Environment, Conservation and Parks before undertaking these essential capital upgrades, which are required to ensure the lagoon’s continued safe and effective operation.

We thank the community for its patience as we continue our work at the Tavistock WWTP while working to address your concerns. For more information on this project:

Winter Fire Hydrant Safety:

With the winter weather arriving, it is important to remember to keep fire hydrants free from snow and ice. In an emergency, every minute matters.

If you have a hydrant on your property, help by clearing the snow and ice away from it.

Posted 5 days ago.

Please do not push snow or ice onto the road or sidewalk when clearing your driveway; this applies to both our urban and rural residents in the Township.

This practice endangers the safety of the motoring public, as well as snow removal equipment and its operators.

Hazards created by pushing snow onto road allowances can include:

  • Frozen snow piles that can cause extensive damage to snow removal equipment and injury to the operators;
  • An increase to the chance of accidents with traffic traveling on the road;
  • Increased drifting snow in the area;
  • Snow piles that cause drainage obstruction in the spring run off.

We appreciate your co-operation in this matter.  It will assist us greatly in keeping everyone safe this winter.

Oxford County recently installed new pedestrian crossovers in Drumbo, Innerkip, Ingersoll, Tillsonburg and Thamesford (coming soon) to improve road safety for pedestrians, cyclists and motorists. Know your role. Pedestrians have the right of way at crossovers. Drivers and cyclists must stop behind the pavement markings and wait until pedestrians have completely crossed the road before proceeding. Drivers and cyclists not following the rules may face fines of up to $1,000 and drivers may incur four (4) demerit points.

Look for the new pedestrian crossovers in our Township, located in Innerkip at:

• Blandford Street at Stratford Street and Young Street

• Oxford Road 33 at Stonegate Road
