Hazards & Risks Covered

Hazard Risk Description
1. WHS Governance, Roles and Legislative Compliance
  • • Lack of clear allocation of WHS responsibilities for temporary plumbing services connection activities
  • • Inadequate understanding of WHS Act 2011 and WHS Regulations duties by PCBUs, officers and supervisors
  • • Failure to identify temporary plumbing connections as construction work and apply construction-specific WHS requirements
  • • Insufficient oversight of contractor compliance with site WHS management plans and client requirements
  • • Poor integration of plumbing temporary services risks into overall project risk management framework
2. Design Management and Temporary Services Engineering
  • • Poor design of temporary water and sewer systems leading to cross-connection or contamination risk
  • • Inadequate design documentation for temporary services, resulting in ad hoc field modifications
  • • Failure to design sufficient capacity for peak construction water use leading to system overloading or failure
  • • Lack of engineering assessment for backflow prevention and pressure management
  • • Insufficient coordination with permanent services design, causing unsafe tie-ins or rework under time pressure
3. Authority Liaison and Network Interface Management
  • • Unauthorised connection to water authority or sewer infrastructure
  • • Incorrect information about network pressure, flow and sewer capacity leading to overload or surcharge
  • • Poor communication with water authority regarding backflow prevention and metering requirements
  • • Failure to obtain and comply with permits or connection approvals
  • • Lack of clarity about responsibility boundaries between site and water/sewer authority assets
4. Contractor Competency, Licensing and Supervision

  • • Inadequate supervision of apprentices or labourers performing critical connection tasks
  • • Poor competence in cross-connection control and backflow prevention practices
  • • Lack of familiarity with local authority and Australian Standard requirements for temporary installations
  • • Over-reliance on a single competent person leading to gaps during absences or turnover
5. Systematic Planning of Temporary Water Supply Connections
  • • Unplanned tapping into existing water lines causing uncontrolled water release or pressure fluctuations
  • • Inadequate isolation planning leading to inadvertent water supply interruption to occupied areas
  • • Poor planning for pressure management resulting in pipe bursts or fittings failure
  • • Insufficient consideration of contamination risks during cut-in to potable water systems
  • • Lack of staged planning for temporary to permanent switchover increasing rework and time pressure
6. Cross-Connection and Backflow Risk Management System
  • • Uncontrolled cross-connection between potable water and non-potable or contaminated sources
  • • Failure of backflow prevention devices due to poor selection, installation or maintenance
  • • Inadequate identification of high hazard zones (e.g. connection to construction tanks, pumps, chemical dosing equipment)
  • • Lack of systematic verification of backflow devices after installation or modification
  • • Temporary cross-connection arrangements (e.g. hoses, manifolds) bypassing permanent controls
7. Foul Sewer Connection and Discharge Management
  • • Connection to incorrect sewer line (e.g. stormwater instead of foul sewer) causing environmental harm and regulatory breaches
  • • Overloading of existing foul sewer system causing surcharge, spills or backflow into buildings or excavations
  • • Release of untreated or contaminated construction wastewater (e.g. sediment, concrete washout, chemicals) into foul sewer beyond authorised limits
  • • Exposure of workers to sewage, pathogens and hazardous atmospheres during connection or inspection activities
  • • Lack of controls for accidental discharge during testing, flushing or dewatering activities
8. Asset Identification, Labelling and Documentation
  • • Misidentification of temporary versus permanent water and sewer infrastructure leading to incorrect isolation or tie-in
