Bore Water Blending Infrastructure Project

Our Solution

Dowdens Pumping and Water Treatment were engaged at the project’s inception, offering our entire service spectrum to assess, engineer, design, specify, construct, install, test and commission, and project manage a turnkey solution.

Pumping equipment supplied is operable via an electronic variable speed drive using a manually set speed selection. Interlocks were provided to prevent the borehole pump from operating for other than limited periods, for example, unless the water treatment plant is also operating.

Delivery of the pipeline included ductile iron cement lined (DICL) pipe laid below ground level to accommodate transfers of 15 l/sec of hot artesian water to the discharge of the Water Treatment Plant filters designed to withstand pressures of 500kPa. The plant was designed to withstand high water temperatures of 75℃ from the constantly flowing artesian bore.

Pipeline construction works included excavation, bedding, laying and backfilling utilising Dowdens experienced infield crew, supervisors and project management. Dowdens Pumping and Water Treatment’s Project Department design team also engineered concrete thrust blocks to restrain the pipeline within the unstable substrate.
