IONA WASTEWATER TREATMENT PLANT

More than 1,000 unique physical assets are examined at the wastewater treatment plant in order to prioritize operations and maintenance, based on probability of failure criteria.

Iona Wastewater Treatment Plant

Physical evaluations were conducted by Black & Veatch at the 110ML/day wastewater treatment plant, located in Vancouver, Canada, to determine the reliability and projected useful life of all major systems and equipment.

Overview

Physical evaluations were performed over an intensive two-week process and involved treatment plant operations, maintenance, and superintendent staff for the facility. More than 1,000 unique physical assets, including buildings and treatment basins, HVAC systems, process equipment, and major electrical and instrumentation systems, were inspected. The results of these physical inspections were entered into a Strategic Asset Management (SAMs) database. These records will be used to prioritize capital improvements at each facility based on probability of failure and consequence of failure criteria.

Current and anticipated regulatory issues were also evaluated to determine the potential impact on existing facilities. These issues included:


  • Emerging total maximum daily load (TMDL) regulations.

  • The effects of biochemical oxygen demand (BOD) and ammonia on receiving streams.

  • Regional nutrient criteria and industrial pretreatment regulations.

  • Biosolids management practices.

  • Sanitary sewer overflow issues.

Results

The client now possesses a detailed database for its asset management that can be used to prioritize capital improvements, as well as operations and maintenance, for years to come.
