Cloncurry Shire Council was successful in obtaining funding through the Works for Queensland program to build a $350,000 water treatment plant to to provide better water quality for residents in Dajarra.

Cloncurry Shire Council mayor Greg Campbell said the tender had been awarded to a specialist company in South Australia.

“We had to outsource for this project as we required a specialist for the reverse osmosis plant,” Cr Campbell said.

“This will be built to Dajarra’s specifications and transported and connected.

“Dajarra will then have unbelievable water.”

Cr Campbell said this upgrade was essential for the Dajarra community.

“Dajarra never had potable water and while it was chlorinated to clean the germs out it was still very hard and had other minerals in it,” he said.

“It wasn’t great water so we are providing a better service to a great little town.”

Cloncurry Shire Council are also upgrading a toilet block facility in town to facilitate both locals and traveling tourists.

The toilet block was jointly funded between Cloncurry Shire Council ($150,000) and the Works for Queensland ($10,000).

Samples of the town supply in Dajarra, collected at the School and the Health Clinic in 2007, exceeded the ADWG for Chloride, Total Hardness, Sodium, and Total Dissolved Solids (as tested by Queensland Health). High values of these chemicals affect the taste or aesthetic quality of water.

Various samples show that the Dajarra town water is unpalatable; however, health-based guidelines are not proposed for each of these specific chemical characteristics. Although the ADWG proposes no health-based guideline value for sodium, it does warn that ‘Medical practitioners treating people with severe hypertension or congestive heart failure should be aware if the sodium concentration in the patient’s drinking water exceeds 20 mg/L.’ Sodium was measured at 209mg/L at the Health Clinic and 387 mg/L at the West End in Dajarra in 2007; see Table 5. The ADWG recognises the effects of high concentrations of these chemicals on water reticulation systems.
