Management

(15) Ensure all new plumbing and water fixture work undertaken through refurbishments, or installed as part of new builds, conforms to best practice water efficiency as defined by Sydney Water. At the time of writing this was measured as three (3) star WELS, per Water Rating, or better.

(16) Ensure that contractors and sub-contractors are provided with the appropriate information and / or training to meet University requirements for water efficiency prioritise the installment of automated control systems and appropriate sub-metering during any new builds or refurbishments undertaken.

Replacements

(20) Ensure that all water fixtures not conforming to best practice (3 star WELS or better, per Water Rating) are replaced as funds become available.

(21) Prioritise replacement of water fixtures in utilities with high usage.

Maintenance Program

(22) Ensure a robust maintenance program is in place by:

  1. checking all plant rooms and large water using sites manually for visible leaks. All such equipment on campus should be checked at minimum once every two weeks; and
  2. identifying all leaks and maintenance requests reported through the Property Service Request Form and responding appropriately. All leaks and maintenance requests will be inspected and action plans identified within a two (2) week period. Actions on mains water and other high pressure leaks are considered urgent and must be dealt with immediately, isolated and repaired as soon as physically possible.

Cooling Towers

(23) Operate cooling towers as follows:

  1. operate cooling towers in accordance with the Water Conservation - Best Practice Guidelines for Cooling Towers in Commercial Buildings or manufacturer’s specifications;
  2. proactively seek opportunities to assist Sydney Water in the further development of best practice guidelines to reduce water and electricity use associated with operation of cooling towers (to be done within the context of the mechanical specification of the product); and
  3. undertake an audit based on the Water Conservation - Best Practice Guidelines for Cooling Towers in Commercial Buildings (for example, refer to page 12) annually, ensuring appropriate follow up action is taken.

Water Monitoring

(24) Monitor water use as follows:

  1. monitor water use, where possible, using online live tools;

  1. sub-meters will generally last for at least ten (10) years, therefore it is necessary to record the date of installation;
  2. continually monitor meter readings and respond to any abnormalities as a possible fault with meters;
  3. if necessary, open the meter and clean out to see if this alleviates issues;
  4. include the testing of sub-meters at the ten (10) year mark into maintenance schedules; and
