Paterson and Kirkwood Reservoirs, Gladstone
Increasing the water storage capacity for Gladstone city and surrounding areas

Background

Gladstone Regional Council has engaged on a program of works to update the region’s water and sewerage infrastructure to ensure that it is able to meet the demands of the growing population in the region. Leed was awarded tenders for two concrete reservoirs.

The 10 ML Paterson 2 Reservoir in Gladstone will bolster the water supply storage capacity for the Gladstone CBD, Gladstone South, Barney Point, West Gladstone and Hanson Road commercial and industrial vicinities.

A new 11 ML reservoir at Kirkwood will add to the existing water storage capacity in Clinton and allowing for growth in the Clinton, New Auckland and Kirkwood areas.

Scope

The scope of the two reservoirs is as follows.

Paterson 2 Reservoir

  • Design and construction of 10 ML post tensioned concrete reservoir, approx 53 m diameter, 6 m high
  • 35,000 m3 earthworks
  • 200 m DN500 DICL pipework
  • FRP concrete valve pits
  • Stormwater drainage and fencing
  • 3,000 m2 road works
  • Electrical and telemetry

Kirkwood Reservoir

  • Design and construction of 11 ML post tensioned concrete reservoir, approx 50 m diameter, 7 m high
  • 100 m DN500 DICL pipework
  • FRP concrete valve pits
  • Stormwater drainage and fencing
  • 2,000 m2 road works
  • Electrical and telemetry

Key features

The original concept design called for a mild steel roof, requiring concrete columns. Based on the Leed team’s extensive tank building experience we were able to recommend stainless steel columns and an aluminium roof be utilised, which will result in a lower maintenance solution in the long term.

Leed is currently undertaking this project with completion scheduled for July 2018. The project is running on time and budget with an outstanding safety record to date.
