Sanitary Sewer Requirements 

  • Prohibits discharge of specific substances. New prohibitions for discharges that may result in, a hazard or adverse effect to the natural environment, or interference with an inspection, or treatment.
  • Augments the regulation of discharges of hauled sewage, hauled waste and leachate to have registered with the Town and have authorized access to sewage works for the purposes of discharge and requires a hauler to comply with any Town procedures or policies that may apply to hauled wastewater. Clarifies the prohibition on discharging sewage causing an offensive odour at the works to indicate what types of odour would be considered to be offensive.
  • A discharger may be permitted to discharge contaminants at concentrations that exceed bylaw with approval of the Town for BOD, Total Phosphorus, and Total Suspended Solids.

Storm sewers

  • Storm sewers now specifically include land drainage works.
  • Clarifies permitted discharges to the storm sewer or land drainage works.
  • New prohibitions have been added, including the discharge of cooling water, oil and grease, and substances that would constitute an offence under provincial or federal legislation.

Food Related Oil and Grease Interceptors

  • Grease and oil interceptors must be installed in compliance with the most current requirements of the Building Code Act and in accordance with the requirements of CSA.
  • Grease and oil Interceptors shall be maintained in accordance with the manufacturer’s recommendation and should be cleaned before the material thickness reaches greater than 25% of the capacity of the interceptor. Cleaning frequency shall be at a minimum once every four (4) weeks.
  • Maintenance schedule and record of maintenance must be submitted to the Town upon request for each interceptor. Records of interceptor clean-outs shall be kept on site for a minimum of two years.
  • Maintenance requirements shall be posted in the workplace in proximity to the grease interceptor.

Vehicle and Equipment Service Oil and Grease Interceptors

  • Every owner or operator of a motor vehicle or equipment service station, repair shop or car wash shall install an oil and grease interceptor designed to prevent motor oil and lubricating grease from passing into the drainage piping which is connected directly or indirectly to a sewer.
  • Each oil and grease interceptor is required to be installed in compliance with the most current requirements of the Building Code Act and its regulations.
  • Oil and grease interceptors shall be inspected regularly to ensure recommended performance specifications are met and to ensure surface oil and sediment levels do not exceed the recommended level.
  • A maintenance schedule and record of maintenance must be submitted to the Town upon request for each installed interceptor. Records of proof of clean-outs and oil and grease disposal shall be kept for a minimum of two years from the most recent inspection and shall retain the most current document of proof for inspection purposes.

Sediment Interceptors

  • A discharger shall ensure a catch-basin installed on its site for the purpose of collecting storm water and carrying it into a storm sewer or land drainage works is equipped with a sediment interceptor and the installation of each catch-basin shall comply with the Town’s standards construction specifications and drawings. All sediment interceptors shall be maintained in good working order and according to manufacturer’s recommendations.
  • Annual maintenance and inspection records must be provided to the Town upon request.
  • A maintenance schedule and record of maintenance for each sediment interceptor must be submitted to the Town upon request.
  • Documentation of each interceptor clean-out and sediment disposal must be kept at the site for a minimum of two years for inspection purposes.

  • Every dental practice shall comply with the Dentistry Act, 1991, S.O. 1991, c.24, and the regulations made thereunder, as amended from time to time, for the management and disposal of amalgam waste.
  • A maintenance schedule and record of maintenance shall be submitted to the Town upon request for each dental amalgam separator installed.
  • A record of inspection and any documentation evidencing the installation of a dental amalgam separator shall be submitted to the Town upon request for each dental amalgam separator installed.

Pretreatment Facilities

  • ​Where required by the Town pursuant to an approved compliance program, the discharger shall install at the site, and prior to the sampling point, a wastewater pretreatment facility at the discharger’s expense and shall ensure any waste products from the pretreatment facility are to be disposed of in a manner which is safe and in accordance with all applicable laws. All documentation pertaining to the pretreatment facility and waste disposal shall be made available to the Town. This documentation shall be kept on site for a minimum of two years, in the case of operational and maintenance documents or records, documents relating to waste disposal, records of sampling and analysis results; and permanently, in the case of all up to date plans, drawings or operational manuals relating to the facility and documents pertaining to any modifications made to the facility.

Discharger Information Reports

  • Prior to any discharge to the municipal sewage works a discharger shall complete and submit a “Short Version of the Discharger Information Report” for review by the Municipality. Such reports shall be returned to the Municipality within 6 months of the day the bylaw has passed.
  • The Town may require the discharger to complete and submit a complete “Discharger Information Report”, where in the opinion of the municipality, the discharger may have a significant impact on the sewage works. Blank forms are available at the Town of Bradford West Gwillimbury Website (www.townofbwg.com).
  • Where a change occurs in the information an updated Discharger Information Report shall be submitted within 30 days of the change.

Agreements, Pollution Prevention Plans & Compliance Programs

The Town may enter into an Extra Strength Surcharge Agreement with a discharger to permit exceedences of the limits set out in the bylaw for any one of the following parameters:

  • Biochemical Oxygen Demand (BOD)
  • Phosphorus, Total; or
  • Suspended Solids, Total

Extra Strength Surcharge Agreement fees are reviewed and adjusted accordingly as determined by the Town based on projected operating and maintenance costs. These fees are necessary to ensure recovery of operation and maintenance costs.

Discharge Agreements include conditions for payment for wastewater treatment of potable water that has not been supplied by the Town. Conditions include a valid Permit to Take Water and a written discharge agreement approved by the Town.

If a sewer discharge exceeds the parameters of the Sewer Use Bylaw, a Compliance Plan may be required to bring discharge within regulation. The Industry for which a Compliance Plan has been approved shall submit a progress report to the Town within a fixed term after the scheduled completion date of each activity listed in the compliance plan.

The Town may require dischargers to develop a Pollution Prevention Plan where the discharger has been out of compliance, is in a compliance program with the Town, or responsible for one or more spills. A Pollution Prevention Plan must be completed by 6 months of being required to do so by the Town and be kept on-site with a copy available for review by the municipality.
