Templates 2 & 3 – Management Review & Actions Template 2 - Management Diagnostic: Please note that the EDC report was based on the most recent data available at the time, and not the 2006 calendar year as indicated in Template 1 and the Department of Commerce audit. For this reason, the average daily water consumption value in the EDC report, differs slightly. Although this aspect is not part of the management diagnostic for the WSAP, it is listed in the Executive Cost Summary of the EDC report, and should be clarified. Template 1 & Department of Commerce audit using 2006 data: 669 kL/day EDC Report (using the latest billing data – several months into 2007): 711 kL/day. Please see attached EDC One-2-five Water Management Report, Pages 3 & 4, the Executive Summary. Template 3 – Water Management Actions: The Sustainable Office, which is still partially in the development stage, with a number of positions and structural issues yet to be decided. This new office is part of the university’s vision towards a sustainable future, and as such, has the full support of the most senior executive’s – it is expected to be fully operational early next year, timeframes are a little uncertain at present. Also mentioned in Template 5, the Office of Facilities Management is to employ a Sustainable Officer early next year – the draft duty statement has already been open for discussion. This person is expected to be a little more technically orientated than the Sustainable Office staff, but at the same time, act as a liaison between the two departments. It is to be expected, that by early to mid 2008, a fully operational sustainable management structure will be in place, with many of the water saving measures listed in the Department of Commerce audit, to be given the highest priority. It is expected that this new structure will also be formally requesting funding, as the need arises. Attached are two reports; The EDC report on Page 9, lists a number of recommended actions. Please note that some of these actions have not been completed by the recommended date, but are currently in progress. Also attached is an Interim Water Policy, drafted by the Sustainable Office, dated November 2007.

Template 5 – Introduction to Plan
Organisation: Macquarie University Brief Introduction: As the name suggests, the university is largely an educational and research based facility, with student accommodation and a number of business related tenancies The University is situated on just over 110 ha, with more than 60 buildings. ____________________________________________________________________ Background / History of Water Savings: Prior to mid 2005, limited involvement in water saving measures and activities. The university focused on meeting general building standards and practises of the time. This included maintenance on leaking toilets and taps (flooding & continuous running water attended to immediately, leaking taps attended to in a couple of days), sensor driven urinals, and drift eliminators on cooling towers. Major plumbing infrastructure leaks were repaired ASAP with the first visual indication of running water. The Sydney Water billing meter was corrected in mid 2005, and the introduction of the WSAP later that year, resulted in water saving measures and sub-metering becoming higher on the agenda. A number of early attempts to satisfy the criteria listed in the action plans were rejected due to inadequate detail in the managerial and technical review areas. Since the beginning of 2007, a number of new senior executive staff, including the Vice Chancellor have joined Macquarie, instigating a new culture, with fresh ideas on sustainability, and the university’s direction and leadership roll in this area. ________________________________________________________________________________ Introduction to Water Savings: There were two areas in the initial WSAPs that required further attention, as indicated by DEUS (now DECC). 1. The Management Structure & Responsibility The Office of Facilities Management whose roll it is complete the report and implement water savings measures, has had a major limitation prior to the new administration, i.e. we had limited control over the academic structure on campus, and their operational and equipment needs. With the new administration, came the establishment of the Sustainable Office (SO). This group would report directly to the senior executive. Included in its agenda, the SO would form campus wide ‘enforceable’ policy on water savings measures, and liaise with the EDC Project Manager. The Office of Facilities Management has also forged ahead with a draft proposal for a Sustainable Officer. It is envisaged this position will be more technically based, (from a building perspective), and will operate in close consultation with the senior executive’s Sustainable Office. Dedicated individuals with direct access to the senior university executive, is the means by which water saving practices and equipment may be enforced across the entire university community.

Introduction to Water Savings (Continued): 2. The Technical Review If you can’t meter it, you can’t manage it. The first requirement of any technical review was to know where the water usage across campus was being consumed. Initially we set out installing a number of sub-meters on targeted, known high usage buildings. For the previous reports, daily readings were taken over a number of weeks. This indicated usage, but not base load or leakage etc. The university at the recommendation of the EDC representative, enlisted the services of the Department of Commerce to do a full technical audit including an initial 12 months monitoring of (web based logging) high daily water use meters. This included 9 sub-meters and 3 Sydney Water billing meters. A further meter (No. 13) was electronically logged for the test period only. ________________________________________________________________________________ Integration with the existing business operations: During the audit, a number of areas were highlighted, particularly with the assistance of monitoring. Overnight base loads indicated abnormalities in the following areas: • Constantly flowing toilets. • Incorrectly adjusted cooling tower ball valves. • Possible leaks in infrastructure. • Research equipment left operational overnight unnecessarily (eg Aspirators). • The phasing out of wasteful research equipment, in particular aspirators, and all potable water direct to waste research equipment. There is a detailed report in Section 9 of the Department of Commerce audit, listing various recommendations, which includes this list and other useful information. From a monitoring and technical review perspective, this flows on to general ‘housekeeping’ including maintenance and response time to faults. Regarding the management review, it is the ability to implement policy, whether it is for building or research equipment. The new sustainability management structure will also enable greater involvement in requests for water saving funding, with dedicated staff striving for targeted goals. Signoff on the Plan ‘I certify that the Water Savings Action Plan has been prepared in accordance with the Guidelines issued by the Minister for Utilities. I am authorised to submit this Plan, on behalf of the designated user, to DEUS (now DECC)’. Robert Kelly Director, Office of Facilities Management
