Executive Summary Gold Coast Water’s (GCW) Price Monitoring Submission presents the information required by the Queensland Competition Authority (QCA), to understand the resources GCW requires to deliver safe, reliable and sustainable water and sewerage services to customers over the two year regulatory period from 2013-14 to 2014-15, including the proposed revenue for those services. GCW’s primary service objectives are to: protect the health and safety of ourselves, and our community provide safe and reliable services for drinking water, sewerage and recycled water perform regulatory requirements ensure prudent and efficient expenditure prevent unacceptable impacts on the natural and built environment. To meet these service objectives GCW has defined specific service outcomes that it aims to achieve over the two year regulatory period. This will provide focus for GCW staff and a framework against which to prioritise available resources. These service outcomes are outlined in Chapter 3. Capital expenditure over the two year regulatory period is projected to be around $126 million (m). As set out in Table 1.1. capital expenditure (capex) is attributable to GCW’s requirements to: service growth (i.e. new capacity and or extensions) excluding assets provided by developers maintain our service commitments and service standards prudently manage the risk

  • Enhancing the Effectiveness of Seqwater's Dam Release Messaging
    Enhancing the Effectiveness of Seqwater’s Dam Release Messaging: A Response to the IGEM Review 12 August 2016 Amisha Mehta, Dominique A. Greer, Paula Dootson, Cindy Hammill, and Vivienne Tippett Queensland University of Technology and the Bushfire and Natural Hazards Cooperative Research Centre For further information, please contact: Associate Professor Amisha Mehta QUT Business School Level 10, Z Block 2 George Street Brisbane QLD 4000 Australia Phone: + 61 7 3138 1798 Email: [email protected] Prepared for Seqwater by QUT Executive Summary This report supports Seqwater’s response to the 2015 Review of Seqwater and Sunwater Warnings Communications by the Office of the Inspector General for Emergency Management (IGEM). Specifically, Seqwater engaged the Queensland University of Technology (QUT) to respond to Messaging: Recommendation 1 by addressing three project objectives: test new and existing dam release messaging, identify evidence-based opportunities to improve the effectiveness of dam release notifications, and support Seqwater’s response to the IGEM requirements. To meet these objectives, QUT researchers, with support from the Bushfire and Natural Hazards Cooperative Research Centre, drew on risk communication models and theories to design a multi-method, multi-phase research program that included community focus groups and surveys. Seqwater messages were modified using principles of effective message design to add specificity, clarity, clear guidance, relevancy and consistency, and tested during all phases. This research program led to the following evidence-based recommendations to improve the effectiveness of Seqwater’s dam release notifications: 1. Adopt modified dam release messages, which were more often effective than existing Seqwater dam release messages.

  • Coomera River Catchment Hydrological Study
    Coomera River Catchment Hydrological Study August 2014 1 Title: Coomera River Catchment Hydrological Study Author: Study for: City Planning Branch Planning and Environment Directorate The City of Gold Coast File Reference: WF19/44/(P1) TRACKS #45484061-v1 Version history Changed by Reviewed by & Version Comments/Change & date date 1.0 Draft Review Review Review Review Distribution list Name Title Directorate Branch Coomera River Catchment – Hydrological Study, August 2014 TRACKS-#45484061-v1 Page 2 of 92 Executive Summary The Natural Hazards (NH) team of the City Planning Branch has undertaken a comprehensive hydrological study of the Coomera River catchment. The Council of the City of Gold Coast (Council) commissioned WRM Water and Environment Pty Ltd (WRM) to undertake a study to review and update its hydrological models to a consistent standard in December 2007. WRM assessed all aspects of model development, calibration, estimation of design discharges and provided a set of recommendations (12.10 ) including a recommendation to update all hydrological models to a consistent standard. Furthermore Monte Carlo methodologies have since become available and it was considered necessary to contrast these methods with the standard Design Event Approach (DEA). This study addresses the WRM recommendations and includes Monte Carlo methodologies for comparative analysis. The main objective of this study is to develop a hydrological model for the Coomera River catchment using the URBS modelling software, calibrate and verify the model against historical flood data, verify the modelling results against Flood Frequency Analysis (FFA) and Joint Probability Analysis (JPA). Finally, estimate the design flood discharges for events ranging from 2 year Average Recurrence Interval (ARI) to the Probable Maximum Precipitation Design Flood (PMPDF) and document all the works to a consistent standard.
