Information for Hydraulic designers

Redland City Council offers an advisory service to hydraulic designers to provide the anticipated performance of the water network based on current hydraulic models.

A Water Network Flow and Pressure Information Report provides information about the flow and pressure in the existing water supply infrastructure. This information is required in order to design and construct water supply and firefighting services in accordance with Australian Standards referenced by the National Construction Code.

A Water Network Flow and Pressure Information Report is not normally required for single dwellings or non-habitable structures such as garages. 

Annual fire system compliance testing should not require this report. Testing of on-lot fire hydrants and/or tests for fire safety compliance purposes should be completed by private operators.

Information included in the Report

The information provided in the report will detail the anticipated performance of the water network based on hydraulic modelling information, as follows:

  • Q-H curves will be provided for both current and ultimate (predicted) planning horizons, based on 2/3 peak hour (PH) demand for the specified node or hydrant.
  • Estimated pressure at zero fire-flow will be plotted on the Q-H curves
  • RCC Fire flow Desired Standards of Service (DSS) limits will be plotted on the Q-H curves for comparison purposes.

Notes

  • The report will not consider the demands generated by the development.  The designer shall satisfy themselves as to the adequacy of the water supply for the proposed development.
  • Information provided in the report has not been verified by field testing, and the certifier or assessing officer is required to confirm the appropriateness of the report results for the purpose of on-lot fire system design.
Fees

The price per application is $600.00 plus GST.

A single application will include up to two nodes or hydrants only.

Timeframe for Response

Please allow four to six weeks from date of payment for processing (depending on demand).
