Unitywater Executive Manager Sustainable Infrastructure Solutions, Mike Basterfield, said the five-million litre capacity asset, which provides water to around 2,000 properties in Peregian Beach and Marcus Beach, was constructed in 1981 and was due for maintenance.

“Following extensive engagement with the community, Unitywater commissioned the art back in 2015. After 10 years in the elements, it is time for a refresh which we are doing at the same time as our maintenance work,” Mr Basterfield said. 

“The native melaleuca artwork is special for Peregian Beach residents and we will maintain the current design on this significant community landmark, which celebrates the area's natural heritage.”

Mr Basterfield said the $3.9 million maintenance project was being delivered under a five-year, $400 million replacements and renewals program, which enables Unitywater to continue providing safe and reliable water and wastewater services across the region.

“The reservoir maintenance work involves a roof replacement, including framing and sheeting, and an amendment to the roof design to facilitate a pitched roof, as well as internal repair works,” he said.

“The works will help ensure water quality by keeping any potential contaminants out of the reservoir and will increase the longevity of the asset to continue supplying water for this community for the next 40-plus years.

“Once the construction works are complete, the mural will be re-painted and receive protective anti-graffiti coatings to help prolong the life of the artwork.”

Noosa Council Mayor Frank Wilkie said the community would appreciate the refreshed design adorning the reservoir.

“It’s great to see Unitywater investing in the maintenance of this iconic water reservoir and large public art piece which has become a prominent Peregian landmark,” he said.

In 2015, Unitywater invited local artists to submit mural designs for the reservoir. The 12 submissions were shortlisted down to four – a skyscape, a Peregian Beach sunrise, a watercolour palette of different Peregian Beach landscapes and a full wrap of native melaleuca trees by Peregian Beach artist Colin Passmore – which was the winning design with 38% of the community vote at the time.

The artwork refresh will follow the construction works which are expected to take about five months.
