DSE Water Savings Protocol
G-MW has more than six years of experience in the installation and use of modernisation technology and the roll out of modernisation in the region. This is in addition to G-MW's ongoing work to understand, measure and quantify components of system loss and to identify opportunities for improved system efficiency. G-MW drew on this experience to assist in the development of the Department of Sustainability and Environment's Water Savings Protocol. For the first time ever, all state water savings projects will be subject to a consistent and rigorous process for calculating the long term water savings. G-MW will use the protocol to estimate water savings achieved from projects underway across the region. All estimates will be subject to independent verification and audit.
DSE's Water Savings Protocol is available from http://www.ourwater.com.au/__data/assets/pdf_file/0016/53530/Water-Savings-Protocol-Audit-Process.pdf
Reports and reference documents
DSE has authorised the release of materials provided by G-MW to DSE to inform the development of DSE's Water Savings Protocol. The relevant material is available in the links below.
The following draft documents have added to the development of the Technical Manual. These documents are based on the best information at the time and are evolving as the program is implemented and testing continues.

Technical Basis For Loss and Water Savings Through and Around Outlets
This document was prepared on 2/10/08 and looked at the appropriate water savings estimates for outlets with the potential for leakage around the meter and through the meter. This is a draft report

Hydro Environmental Report
Hydro Environmental was engaged to provide an expert review of particular aspects of G-MW documents which relate to the identification of the potential water savings. This report by Hydro Environmental does not review every aspect of the two reports and only addresses the issues identified as required by G-MW, DSE and WFR in the Project Brief.

Program for Water Savings Audit Program
DSE appointed Cardno to audit the water savings achieved to date by G-MW's modernisation projects. The audit will take place during September and October 2009 and once complete the audited volume will be announced publicly. Until the Audit is complete, beneficiaries of the projects cannot access their share of the water savings.
