Infrastructure Charges Schedule

Unitywater's Infrastructure Charges Schedule replaces the water supply and sewerage aspects of the Councils' Adopted Infrastructure Charges Resolutions.

This Schedule applies to Unitywater's geographic area (Moreton Bay, Sunshine Coast and Noosa) and is separate to infrastructure charges imposed by participating Local Governments under their own infrastructure charges resolutions.

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.

Connections Administration Manual (PDF)

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, approval conditions for new connections, and may assist you in preparing your application and undertaking your project.

Netserv, SEQ Code, Unitywater’s Infrastructure Standards and Products

Water Netserv Plan

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

SEQ Code

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 Infrastructure Standards

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.

Unitywater Infrastructure Products

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.
