Many industrial, commercial and institutional operations produce liquid waste that is not suitable for discharge to the sanitary sewer or storm sewer systems. These wastes are generated at operations such as:
- Restaurants (grease interceptors)
- Photo processors (fixers)
- Automotive repair shops (oil water separators)
- Dry cleaners (solvents from dry cleaning machines)
- Parking lots (catch basins)
- Laboratories (various chemicals)
These wastes are considered to be high-strength liquid wastes or obstructive wastes. Discharge of these wastes to the sanitary sewer or storm sewer systems is illegal and would be in direct contravention of the Sewer Regulations Bylaw No. 2664-2017. These wastes must be disposed of properly by a licensed carrier who picks up the waste and transports it to a proper disposal facility.
Wastes generated from grease interceptors within Abbotsford and Mission may be transported for treatment at the TLW Facility located at the JAMES Wastewater Treatment Plant. Prior to discharging at the TLW Facility, the carrier must first dilute the grease interceptor waste to a ratio of 1:10 with septage in order to minimize the loading on treatment processes. Applicable disposal fees will apply as outlined in the Procedure Manual.
Wastes generated from the other operations listed above (aside from grease traps) are not authorized for disposal at the TLW Facility and must be disposed of in accordance with applicable regulations.
Refer to the Procedure Manual for a detailed list of wastes authorized for disposal at the TLW Facility.
