Upgrading critical pumping infrastructure to support increased water demand and improve supply reliability for Parkes.

Parkes Shire Council

Parkes, New South Wales

Wet Well Pump Station Augmentation

[Project Background]

Strengthening Water Supply Infrastructure for a Growing Community

Parkes Shire Council initiated upgrades to the Lachlan River pump station to support growing demand for bore and river water across the region. The project formed part of a broader initiative to develop a new pre-treatment facility that would pump treated water to the Parkes Water Treatment Plant for further processing and distribution.

The existing pump station required augmentation to increase pumping capacity and ensure reliable delivery of water for industrial and irrigation use across the township.

[Scope Of Works]

Operating in Sensitive and Live environments

Augmentation of the existing river pump station to increase operational capacity and support growing water demand across Parkes.

Installation of new submersible pumps within the existing wet well structure

Replacement of pipework, valves, guiderails, and associated mechanical infrastructure

Construction of concrete lid systems and access infrastructure

Electrical upgrades and integration of new pumping equipment

[Outcome / Key Features]

Delivered Pump Station Capacity Upgrade

Outcome

Installation of Flygt NP3315 submersible pumps within the existing wet well
Upgrade of the pump station manifold system to support an additional pump installation
Replacement of critical mechanical infrastructure including valves, pipework, guiderails and associated metalwork
Electrical system upgrades to support the modernised pump station operation
Construction of a new reinforced concrete lid with McBerns lid system

Key Features

Installation works carried out within an 11-metre-deep confined wet well environment
Pump installation delivered using Franna lifting operations and suspended work platforms
Strict confined-space safety procedures implemented including gas monitoring and extraction systems
Shutdown coordination undertaken to minimise disruption to Parkes water supply
Safety systems implemented to manage high-risk lifting and working-at-height activities

[Environmental Responsibility]

Protecting surrounding waterways during infrastructure upgrades

Environmental controls were implemented throughout the upgrade works to protect the nearby river environment and prevent contamination of the wet well during construction activities. Spill prevention measures and controlled work procedures ensured the integrity of surrounding water resources.
