Lachlan River Pump Station Augmentation

Parkes Shire Council is currently advancing infrastructure to meet the growing demands for bore water within the township of Parkes and local surroundings. The forthcoming construction of a pre-treatment facility for river and bore water signifies a pivotal step in enhancing water supply reliability and quality for local residents and industries. The water will be primarily used for industrial purposes and irrigation.

The necessity for this pre-treatment facility arises from the escalating growth and heightened water requirements within the community. Once operational, the facility will serve as a crucial link, pumping treated water directly to the Parkes Water Treatment Plant (WTP) for further processing and distribution.
As part of this comprehensive initiative, the existing river wet well pump station, responsible for delivering water to the pre-treatment facility, is slated for significant upgrades. The primary objective is to bolster the station’s capacity and efficiency by upgrading two single submersible pumps (duty/stand-by) and integrating an additional third pump. This augmentation aims to fortify the station’s capability to meet increased water demand and ensure continuous operational reliability.

The scope of works encompasses not only the installation of new pumps but also the comprehensive replacement of all associated metalwork, valves, electrical components, guiderails, and piping within the wet well and valve pit. This holistic approach ensures that all critical infrastructure components are modernized to current standards, enhancing operational efficiency and minimising maintenance requirements.

In conclusion, the augmentation of the wet well capacity and installation of new pumps at the river pump station represent a critical investment by Parkes Shire Council in ensuring reliable and high-quality water supply for the growing needs of the area. This initiative underscores the council’s dedication to meeting present and future water demands while fostering sustainable growth and community well-being.

Challenges, Key Features, and Outcome of Killard Project

Challenges:
1.Critical Working Timeline and Water Shutdown Management:

• • Managing a critical working timeline to minimise water shutdown periods and maintain uninterrupted water supply to Parkes township and critical industries.
  • Coordination with Parkes Shire Council (PSC) to schedule shutdowns during off-peak times.
  • Staggered work pace due to water shutdown constrains

2.Confined Space and Suspended Work Operations:

• • Navigation and execution of tasks within a confined space environment inside the wet well, requiring specialised safety protocols and equipment such as gas monitors and extraction fans.
  • Suspended work operations with man cage and Franna adding onto
  • Ensuring compliance with confined space entry procedures and continuous monitoring to mitigate risks associated with confined space work.
  • Restrictions on the use of emissive power tools

3.High-Risk Work Environments:

• • Addressing high-risk elements such as Franna lifting operations, working at heights, and handling heavy equipment during pump installation and infrastructure upgrades.
  • Implementation of comprehensive risk assessments, safety plans, and emergency response protocols to safeguard personnel and assets.

Key Features:
1.Installation of Submersible Pumps and Infrastructure Upgrades:

• • Successful installation of NP3315 Flygt submersible pumps at the bottom of the 11-meter deep wet well.
  • Upgrading the manifold system to accommodate an additional pump, enhancing operational capacity and flexibility.

2.Construction of Concrete Lid with McBerns Lid System:

• • Design and construction of a robust concrete lid equipped with the McBerns lid system to support the new, larger pumps.
  • Ensuring structural integrity and safety while facilitating ease of access for maintenance and operational activities.

3.Implementation of Guide Rail System and Safety Measures:

• • Installation of a secure guide rail system with chains to enable safe extraction and maintenance of pumps.
  • Implementation of stringent safety measures to mitigate risks associated with confined space entry, working at heights, and high-risk activities.

Outcome:
1.Operational Efficiency and Reliability:

Enhancing the operational efficiency, reliability and capability of the pump station through the installation of modern submersible pumps and upgraded

infrastructure.
Improving pump performance and system resilience to meet the increasing water demands of Parkes Shire Council area.

2.Safety and Compliance:

• • Successfully executing high-risk work activities while prioritising safety and environmental compliance with industry standards and regulatory requirements.
  • Mitigating potential hazards associated with confined space entry, working at heights, and critical infrastructure upgrades.

3.Environmental Stewardship:

• • Upholding environmental stewardship by implementing measures to protect the nearby river and ensuring minimal ecological impact during project execution.
  • Adherence to environmental regulations and best practices to safeguard natural resources and preserve water quality.
  • Additional measures to prevent well contamination with possible spills or inadequate material use.

In summary, the Killard project for Parkes Shire Council exemplifies effective project management in overcoming challenges associated with critical timelines, confined space operations, and high-risk work environments. The successful implementation of key features has resulted in improved operational capabilities and safety measures, contributing to enhanced water supply management and infrastructure resilience for the community of Parkes
