Industrial Pretreatment

Manufacturing and other industrial users may be noncompliant without pretreatment systems

Manufacturers often have a number of different pretreatment setups on site. Halifax Water regulates all pretreatment facilities connected to the Halifax Water wastewater system, and may require customers to provide details of their system including but not limited to:

  • Relative location of their system (e.g. upstream of a Monitoring Access Point)
  • Plumbing drawings
  • Design specifications showing what is being removed from the wastewater and how
  • Disposal records of the recovered waste
Record Submission

Operators of pretreatment facilities connected to the Halifax Water wastewater system, if requested, are required to submit (at minimum) quarterly sample results based on the parameters set out in Section 66 of the Halifax Water Regulations, from an accredited laboratory. If you have any questions regarding whether or not you should be sampling your wastewater discharge, please contact Halifax Water.
