EUSSMb Carry out maintenance of sewage pumping plant and equipment

Overview

This standard is about carrying out maintenance on sewage pumping plant and equipment. Maintenance can be planned as part of a maintenance routine or unplanned in response to identified or unforeseen problems.  

It involves shutting down or isolating equipment, carrying out maintenance, monitoring safety, reporting defects and malfunctions and disposing of waste.

This Standard is for operatives in sewage pumping stations who carry out first line operational maintenance of sewage pumping plant and equipment.

Performance Criteria

You must be able to:

  1. check all equipment, materials, tools and parts recommended by manufacturers are available and comply with organisational requirements before planned or unforeseen maintenance work commences
  2. shut down or isolate, or request designated people to shut down or isolate, plant or equipment being worked on in line with permits to work
  3. inform affected people when plant and equipment is to be shut down, the duration of shutdown and when plant and equipment will be re-started and recommissioned
  4. display predetermined safety warnings in visible locations in advance of planned or unforeseen maintenance activities
  5. carry out planned or unforeseen maintenance in line with site specific organisational procedures and within the timescales and sequence specified in maintenance schedules
  6. use instruments and monitoring equipment to carry out planned or unforeseen maintenance in line with manufacturers' and organisational specifications and safety procedures
  7. use relevant tests, checks and the results of monitoring activity to check for unforeseen malfunctions or other maintenance requirements
  8. monitor conditions throughout planned or unforeseen maintenance work to ensure it poses no risk to workers, site or environment
  9. restore plant and equipment to specified operational performance when planned or unforeseen maintenance is finished, in accordance with organisational requirements and safety procedures
  10. dispose of waste materials and unwanted parts in accordance with safe working practices and organisational procedures
  11. report mechanical or electrical malfunctions or problems with maintenance activities which you cannot resolve in line with organisational procedures
  12. complete and store maintenance records and reports in accordance with organisational procedures, providing access to designated people on request

  3. the components of sewage pumping plant and equipment and pump control equipment, their functions and typical operational sequences
  4. how to source and check equipment, materials, tools, parts and consumables including verifying inspection dates
  5. the characteristics of faulty monitoring equipment and instrumentation and the outcome of equipment and instrumentation breakdown during unforeseen or planned maintenance activities
  6. where to obtain and how to interpret drawings, specifications, manufacturers’ manuals and maintenance schedules
  7. requirements for safe work zones and predetermined actions to take in instances of safe zone infringements
  8. how to carry out and interpret performance tests, operational checks, remote monitoring and sensory checks including observation, noise, heat, vibration
  9. the common causes of faults and damage to sewage pumping plant and equipment and actions to take to resolve them, including making adjustments, replacing parts, lubrication, cleaning and removing blockages
  10. waste disposal procedures including for oils and chemicals and their containers, used gloves or soiled PPE, metal components, rags, grit, fat
  11. procedures and the factors to be considered for isolation, permit to work, diverting flows, operating temporary plant and shut down of plant and equipment, and who has authority to carry this out
  12. typical and unusual mechanical and electrical problems and problems which may occur during maintenance, how they can be avoided and the scope of your responsibility for resolving them
  13. who may be affected by planned and unforeseen maintenance work and organisational procedures for communicating with them including control room, onsite colleagues or contractors, upstream or downstream asset controllers, customers
  14. who to report progress or problems that cannot be resolved to and the organisational procedures for doing so
  15. the organisation’s procedures for recording and storing information and their purpose in audit trails for quality assurance, health and safety and regulatory requirements
