Campus Infrastructure Services is looking to improve water
efficiency in every area. Major buildings are designed to
the highest practicable standards and refurbishments will
try to incorporate the latest water savings technologies.
Even our maintenance teams are looking for what they can
do to eliminate leaks, maintain potability and replace water
intensive systems with efficient alternatives.
By changing
the way you use water in your building, laboratory or workshop,
you can reduce maintenance, improve efficiency, help the environment
and show our students how to do the same.
The Utility Information System is available to every staff member
and every student. You can see how much water your building or area is
consuming and in many cases the results of your water-wise initiatives.
This online system may also be used as an education tool or to
identify anomalies to the management or the administration.
Please read below about how water is used on campus and what you can do.
The University
has previously received an award by the NSW government for one
individual water-saving champion.

The Utility Information System
presents up to five displays of water consumption
data for each meter.
- Display One - presents Real-time
Water Demand Profiles (updated automatically every 15 minutes)
for a limited number of meters located on Main Campus only.
- Display Two - presents Monthly
Bar Graphs for Total Water Consumption and Cost.
- Display Three - presents
a Recent Eight Day Water Demand Profile for a limited number of
meters located on Main Campus only.
- Display Four - presents
an Historical Sixteen Day Water Demand Profile for a limited number
of meters located on Main Campus only
- The University water tariff is divided into charges for each kilolitre for water
consumption , each kilolitre for sewerage usage and a variety of water, sewerage and waste
service charges. The prices are set by
IPART and as published on the
Sydney Water website.
- Sewerage consumption is calculated according to the Sewerage Discharge Factor,
which for the university is estimated to be 70%. This means that for every 100 litres
of tap water, 70 litres is assumed to run into the sewerage system.
- Bookmark and visit your university building's internet site/s on
at least a monthly basis. Learn how to analyse your building's monthly
consumption water data.
- Where appropriate, turn off all water consuming equipment when not
in use including over night and weekends.
- Install simple flow indicators (eg rotometers, indexed valves etc)
and minimise water flow rates where equipment cannot be turned off.
- Identify areas within your building where utility savings can be
made then liaise with CIS on x12264.(eg efficient shower heads, water
flow reduction devices or flow indicator devices)
- Report all faulty taps and leaking toilet cisterns to CIS Service
Desk on telephone x17838.
- Report continually wet or soggy grassed areas (as well as wet pavements,
etc) as a possible indicator of a concealed leak.
- Monthly Water consumption is, in part, seasonal. The increases
over summer may be attributed to water losses in cooling towers,
back flushing of cooling towers, oval irrigation and local garden
irrigation (Note - your building meter may also measure the water
consumption of local garden watering systems).
- If an increase in monthly water consumption exists (with temperature
conditions and building use relatively average), further investigations
should be carried out to determine a problem does not exist. A substantial
increase without a change in building population or teaching hours,
suggests an unidentified discharge to drain from mechanical plant
or alternatively, a possible water leak.
- Increases in consumption are normally attributed to: faulty tap
wear / toilet facilities, unidentified leaks, departmental equipment
not being fully turned off, faulty garden / lawn irrigation systems,
faulty float valves in cooling towers and header tanks.
