Classification of a water or wastewater facility/system provides an indication of the degree of knowledge and training that is required of an operator of that facility. The EOCP classifies facilities in BC and Yukon in accordance with pertinent regulations, and the Best Practices guide established by the Canadian Water and Wastewater Operator Certification Committee in conjunction with the Association of Boards of Certification.

Facility classifications include small water systems, small wastewater systems, water distribution and treatment systems (Levels I to IV), wastewater collection and treatment systems (Levels I to IV), and industrial wastewater treatment systems (Levels I to IV).

Please contact the EOCP office for details

Classification Models and Forms:

The EOCP has recently updated its facility classification models.

If you wish to have the following facilities (re)classified, please contact the EOCP office.

  • Water Treatment
  • Water Distribution
  • Wastewater Treatment
  • Wastewater Collection

For classification of Small Wastewater Systems that serve under 500 people please continue to use the Small Wastewater System Classification Form.

For classification of Small Water Systems that serve under 500 people please continue to use the Small Water System Classification Form

What is pre-classification?

The EOCP offers pre-classification for facilities which are new or going through major upgrades. Pre-classification is done using facility classification models and an interview with either the Chief Operator or design engineer to understand how the new or upgraded facility will be classified.

Why should I pre-classify?

If you are involved in the design of a new facility or system, it can be helpful to understand what the classification will be at the time of commissioning, so that the utility can ensure there is certified operator in place with the right certifications.

If you are completing upgrades at your existing facility or system, it is also helpful to know if your operators will require further training.

If you are involved in the design of a new facility or system, the pre-classification exercise can help with selecting a preferred method of treatment which aligns with the needs of the community. For example, a small remote community may not be able to support having a Level III or IV certified operator. The pre-classification form will aide in selecting specific treatment /distribution/collection options that will result in a lower classification if that is a desired outcome.

How do I pre-classify?

At any point during the design stage, before the new or upgraded facility is commissioned, contact the EOCP to arrange a pre-classification interview. You will be asked to complete an excel spreadsheet which provides details on the infrastructure and operations influences planned for the new facility. You will also be asked to provide a design drawing or schematic of the facility showing any new components.

How much does it cost to pre-classify?

The cost to pre-classify a facility or system is $50+GST.

Is pre-classification offered for all facility types?

Pre-classification can be done for water treatment, water distribution, wastewater treatment, wastewater collection, and small systems.

Will the classification of my facility or system change once it’s commissioned?

It is very unlikely that the classification will change, however, depending on the amount of information provided at the time of pre-classification and any changes made to the operational influencers, there is the potential for an increase or decrease. These concerns can be discussed with the EOCP at the time of pre-classification. An EOCP staff member will be able to identify if a facility or system is likely to be on the fringe of a specific level.

Whom should I contact at the EOCP to get a facility pre-classified, or if I have any questions?
