CQU Plumbing Supervisor Andrew Dittman checks a water meter at CQU RockhamptonWith water conservation a hot topic in the Sunshine State, Central Queensland University Rockhampton has reduced its water consumption and saved the University thousands of dollars in water rates.

CQU's Division of Facilities Management has reported initiatives started in 2003 and carried through 2006 have resulted in a reduction in the consumption of water by 29,300 megalitres and savings in the order of $78,000 to date.

Division of Facilities Management Business Manager Debbie Wolhuter said a few simple but effective processes and protocols have been actioned to bring about this significant outcome.

Commencing in 2003, control devices were fitted to hand basins and showers to reduce tap flow from about 26 to 6 litres per minute, and shower head flow from 16 to 12 litres per minute. Other bathroom modifications included fitting urinals with flushing sensors and retrofitting dual flush to all toilets.  High use buildings were fitted with individual water meters which now allows for checking patterns and correcting usage anomalies, such as hidden leaks.

Externally, sprinkler systems had timers fitted to work during the night rather than the day to reduce evaporation losses and reduce the need for watering to twice a week. With the aid of Community Water Grant funding, a rainwater tank has been installed at nGundanoo Imbabee Child Care Centre.

Looking to the University's future, air conditioners will use air-cooled condensing systems rather than cooling towers, and new buildings will comply, as far as practicable, with environmentally sustainable principles including water conservation.

The Division of Facilities Management is also exploring effective ways to harvest some rainwater runoff and possible use of evaporation pond water.
