Water Meter Calibrations

Trillium Measurement and Control have been recently involved in providing the service of calibrating the Water Meters used to monitor the discharge of private water (i.e. groundwater or surface water) into the Toronto sewer systems. This is an agreement that was issued by the Environmental Monitoring & Protection Unit of Toronto Water. As per the Sewers By-law (TORONTO MUNICIPAL CODE CHAPTER 681, SEWERS), in order to issue a discharge approval for the discharge of private water, such as:

  • groundwater (dewatering)
  • surface water
  • rainwater
  • stormwater

to a City storm or sanitary/combined sewer via a catch basin and/or maintenance access hole, a suitable flow metering system (Neptune) must be installed to measure the private water being discharged and must be provided to Toronto Water.
