What will be happening on site?

NOTICE - November 14, 2023:​ 
Trickling Filter Decommissioning
Nov. 28 – Dec. 9, 2023

Construction of the Nelson Wastewater Treatment Facility continues.  One of the next key steps is to remove the first of the existing trickling filters.

 

The trickling filter technology is being removed because it cannot meet future water quality requirements. Trickling filters have historically been a source of odor generation and will ultimately be replaced with a modern biological nutrient removal system.

Details about the activity are as follows:

  • The location of this infrastructure is highlighted in yellow in the figure. 

  • Starting November 28th, the team will be demolishing the trickling filter so that future infrastructure can be built in its place.  

Nelson WWTF - update
  • During this period, there is an increased potential for odor generation.  The team has taken several measures to minimize this to the extent possible, including the installation of chemical systems meant to prevent the odor from occurring and scheduling to minimize the duration of the activities to the extent possible.  

  • Dates noted may need to be adjusted to due weather or other factors.​

 

Thank you for your understanding.  We will work to complete this task as quickly as possible while maintaining a safe work environment for our team and the community.
