Dowdens Pumping and Water Treatment met with Orionstone who wanted one of their unused buildings on site in Paget, Mackay to be converted into a wash bay.

Dowdens Pumping and Water Treatment suggested they utilise the two overhead gantries already present on site, and advised they would need several large wash cannons plus a hot / cold pressure washer to efficiently clean the large mining machinery Orionstone had coming through the site.

Because of the high volume and pressure of water required to power the cannons Dowdens also recommended a variable speed pressure system. Orionstone had limited town water supply volume, so then Dowdens installed 2 x 25,000 litre rain water tanks as reservoirs. These are both fed by town water and rainwater to ensure the wash bay has uninterrupted supply.

As most of the machinery to be washed is extremely large it was a requirement that both sides could be accessed and operated independently.

Dowdens supplied a 'Washmate 5' Hot / Cold Pressure Washer, along with a remote reel for easy access across the opposite side of the wash bay. A remote control box to control the pressure washer remotely was also installed on site.
