Updated UDS manual now available 

New requirements for network administration, design and installation in land development and subdivision projects have just been released in Western Australia.

The updated Underground Distribution Schemes (UDS) Manual, now in its 12th edition, details a range of changes set to take effect from 1 July 2024.   

Western Power Head of Grid Transformation, Ben Bristow, said the updated UDS manual was the result of significant consultation, drawing from more than 600 feedback submissions, internal workshops and industry forums.

“Thank you to the Urban Development Institute of Australia, the Property Council of Australia, participants of the Subdivision Design Forum and other industry stakeholders for their valuable input into these changes,” Ben said.

“We’ll continue to work closely with these stakeholders to continually update the manual to ensure it contains the latest advice and we can meet the evolving needs of our customers, community and industry.”

Changes to the UDS manual include:

  • new guidelines for existing overhead network assets within road reserves and properties 
  • revised developer responsibilities and clarifications
  • enhanced focus on network safety in design requirements
  • updated requirements for network reliability to advance fault finding and restoration
  • amendments to flood and water table considerations, as well as point of supply connections 
  • modified cable placement near retaining walls and service pillar locations
  • a new option allowing developers to conduct a simplified connection service subdivision where the project involves civil works
  • removal of Serviced Uncleared De-Energised Lots option and clarified clearance conditions 
  • new UDS Structure diagram highlighting stakeholder roles and how they collaborate.

A two-month transition period will be provided to help industry align with the new requirements.
