Narromine Concept Design

Narromine Concept Design

Overview

City Water Technology is working with Narromine Shire Council to develop the concept design for the upgrade of the Narromine Water Treatment Plant.

Narromine currently depends on groundwater bores and a temporary treatment plant that was installed during drought conditions. The project is focused on developing a long-term treatment solution to improve drinking water security, water quality and compliance for the community.

Project summary

  • Reviewing and refining the preferred WTP upgrade option for a 7.5 ML/day concept design.
  • Assessing treatment barriers to address pathogens, iron, manganese, turbidity and variable raw water quality from multiple sources.
  • Developing the process concept, site layout, drawings, risk inputs and supporting documentation required to progress the project.
  • Positioning the project for the next stage, including technical specification development, D&C procurement readiness and future grant funding opportunities.

Services Offered

  • Desktop review, site inspection and design basis development
  • Jar testing and raw water quality assessment
  • Process selection, sizing and operating philosophy
  • Development of PFDs, P&IDs, hydraulic profile and equipment lists
  • Critical control point and operational control point development
  • Concept design development for the preferred upgrade option
  • Risk workshops, stakeholder input and value engineering
  • Support for approvals, procurement readiness and future technical specification development

Need

Narromine relies on five groundwater bores, but the raw water presents significant quality and security challenges including iron, manganese, turbidity, quartz sand, bentonite, and a high risk from chlorine-resistant pathogens.

The existing temporary WTP was commissioned during the 2018-2020 drought and is not a complete long-term solution for Narromine’s future water quality, treatment barrier and capacity requirements. Narromine Shire Council needs a robust concept design to support Section 60 approval and the next phase of project delivery.

Solution

Develop a concept design for the preferred Narromine WTP upgrade option, based on a 7.5 ML/day treatment capacity, to support a long-term, fit-for-purpose water treatment solution for the township.

The concept design is refining the treatment process and site arrangement, including raw water balancing and oxidation, coagulation, flocculation, clarification, ceramic membrane filtration, UV and chlorine disinfection, treated water storage, sludge handling, electrical and control systems, and environmental and approvals support.

As the project is still in progress, the concept design will continue to be developed into a technical specification and procurement-ready package to support a future Design and Construct contract.

Benefit

Provides a clearer pathway for Narromine Shire Council to replace the temporary plant with a robust long-term treatment solution that improves drinking water quality, reliability and regulatory compliance.

Progresses the project toward Section 60 approval, technical specification development, D&C procurement readiness and future grant funding applications.
