Unitywater infrastructure and maps

Detailed Infrastructure Plan (DIP) 

The existing infrastructure map shows you the location of our water and sewerage infrastructure and detailed information on location levels. If you still need an official document you can request a Detailed Infrastructure Plan (DIP) online in My Account. This has the same information as the online map. There is a cost for a DIP and a 5-day turnaround.

Policies, codes and manuals 

Current legislation requires that your obtain Unitywater’s approval before any work can commence on new connections, disconnections, or alteration of existing connections to Unitywater’s water or sewerage networks.

The following documents outline the application process and approval conditions for new connections, and may assist you in preparing your application and undertaking your project. 

Applications and approvals prior to 1 July 2014

Build Over or Near Infrastructure technical documents

Drawing standards and templates

Ensure your development application is assessed as quickly as possible by providing high quality information and drawings of what you plan to construct.

After construction, you must also ensure that any drawings you provide of the infrastructure you constructed comply with our record-keeping standards. This is a pre-requisite for you receiving your certificate of completion as this information is critical for Unitywater’s ongoing maintenance and management of the network.

The Connections Administration Manual has more information on documentation requirements.

Our Netserv Plan presents Unitywater’s business strategies for managing our growth and investment. 

Appendix B of the Unitywater Water Netserv Plan contains information about both Planning Assumptions and the Schedule of Works.

The Netserv Plan Planning Assumptions are also shown within an interactive map. They include network demand and demographic planning assumptions.

The Schedule of Works maps are available to view within our interactive map. They show future plans for trunk infrastructure to meet growth projections and land use assumptions. They help developers who are planning long-term or large-scale projects. 

Their purpose is to inform Unitywater's participating councils, customers and developers of our plans for delivery of trunk water supply and sewerage infrastructure. This infrastructure will serve planned growth in the Unitywater service area in accordance with the South East Queensland Regional Plan and the Planning Schemes of the participating councils (i.e, Moreton Bay Regional Council, Sunshine Coast Council and Noosa Council). 

The South East Queensland Water Supply and Sewerage Design and Construction Code (or the SEQ Code) is applicable to all planning, designing and/or constructing of water supply and sewerage infrastructure that will be owned by one of the SEQ water service providers. It is of interest to developers, engineers, consultants, constructors, product suppliers, State government, local government, etc.

The SEQ Code includes:

  • a listing of products and materials accepted for use within the SEQ water industry

  • design criteria for water supply and sewerage assets

  • separate codes for planning, design and construction of:

  • water supply assets

  • sewerage assets

  • sewage pumping stations

  • vacuum sewerage systems

  • pressure sewerage systems

  • specification for preparing asset information. 

Unitywater Technical Notes to the SEQ Code 

Pr11051 - Use of X Type Maintenance Holes Technical Note 

Pr11085 - Trench Plate Technical Note

Pr11087 - Bridging Structures over Pipes Technical Note

Pr11088 - Thrust Type Dismantling Joint with Separate Adapter Studs Technical Note

Go to the SEQ Code website

The following infrastructure standards, specifications and work practices have been developed by Unitywater to complement and expand upon SEQ Code requirements.

The Unitywater Technical Specification Reference Guide provides guidance to the engineering specifications or documents that may be used when undertaking design, construction, commissioning and/or handover of assets.

If you identify a potential conflict between the two sets of requirements, please contact development.services@unitywater.com and request clarification of the issue.

The performance of water supply and sewerage networks is critically dependent upon the quality of the adopted technical standards and the attributes of the products and materials used in their construction. The appropriate selection of approved products is critical to achieving asset life expectancies, financial performance, operability, serviceability, inventory management, and ultimately community expectations. Only approved products shall be used, unless specific concession is obtained from Unitywater.

For Accepted Civil Infrastructure Products and Materials (IPAM) refer to SEQ Code.

For Accepted Mechanical Infrastructure Products and Materials (IPAM) refer to SEQ Code.

To have new Civil or Mechanical IPAM added to the Accepted IPAM Lists use the process described on SEQ Code and use the Product Appraisal Request Form that can be downloaded from the webpage.

For Accepted Electrical Equipment refer to F10678 - Accepted Electrical Equipment List.

To have new Electrical Equipment added to the Accepted Electrical Equipment List send details of the electrical equipment to products@unitywater.com.

For Accepted Sewage Treatment Plant Equipment refer to F10975 - Preferred Equipment List for Sewage Treatment Plants

To have new Sewage Treatment Plant Equipment added to the Preferred Equipment List for Sewage Treatment Plants send details of the equipment to products@unitywater.com. Please note that this list is it’s infancy so may not include all equipment currently used.

The Connections Administration Manual details Unitywater’s administration processes for connection applications, assessments, approvals, as well as construction and handover of infrastructure constructed by a developer. 

It will help you understand how the SEQ code and Unitywater’s Connections policy are linked together and applied in practice.

Connections Administration Manual (PDF 2.6MB) 

Your application for approval will be assessed in line with the Unitywater Connections policy (as specified in the South East Queensland Water (Distribution and Retail Restructuring) Act 2009).

The Connections Policy outlines:

  • how to request a service advice notice

  • how to apply for connection approval or amend an approval

  • what to do when an approval lapses

  • the application processing timeframes

  • the approval criteria and conditions for:

  • different categories of connections

  • construction maintenance and defects liability

  • applications to connect outside Unitywater’s connection area (including outside Unitywater’s restricted connection area)

  • the locations where Unitywater provides connection to our infrastructure and intends to extend current infrastructure.
