What is Trucked Liquid Waste?

Trucked Liquid Waste is a category of waste that, due to the level of contamination or health/environmental risk it poses, cannot be legally be disposed of down the sanitary sewer or in the stormwater system.  These wastes are usually produced in large volumes and can come from businesses such as:

  • Restaurants (grease interceptors)
  • Car washes (vehicle wash interceptors)
  • Automotive repair shops (oil water separators)
  • Parking lots (catch basins / stormwater rehabilitation units)
  • Photo processors (fixer)
  • Laboratories (various chemicals)

These wastes, and other high strength wastes, must be transported, or trucked, by a hauler to a proper disposal or treatment facility.

Why is TLW a concern?

When waste is generated by a facility, the business owner is responsible for ensuring proper disposal and compliance with applicable legislation or regulations

The Capital Region has an environmentally aware business community who want to do the right thing to ensure protection of human health and the environment. The CRD TLW program was created to promote proper disposal options for trucked liquid waste.

The goal of the TLW program is to ensure that this waste is handled and disposed of in an appropriate and responsible manner to protect human health and the environment. To achieve this, the CRD is working in partnership with TLW service providers and others to promote appropriate disposal options for TLW generated in the Capital Region.
