Northmead, New South Wales

Bypass Infrastructure + Early Works Package

[Project Background]

Replacing Emergency Pumping Infrastructure

The Northmead Pump Station replacement project was initiated to replace a temporary pump station that had previously been installed under emergency conditions. The new infrastructure was designed to restore long-term operational reliability to the wastewater network in the area.

Killard was engaged to deliver enabling works and bypass infrastructure to support the construction of the new pump station and ensure continuity of wastewater flows during the replacement process.

Installation of dual OD630 PE rising mains connected to the new pump station system
Installation of DN200 gravity sewer connection infrastructure
Construction and installation of dropper pipe into the existing inlet manhole to support bypass operations
Integration of works with the existing Sydney Water wastewater network

Key Features

Works delivered within a complex site located at the confluence of three waterways
Construction sequencing developed to address restricted site accessibility
Multi-disciplinary delivery including civil, mechanical, FRP and pipeline installation works
Early works package delivered while design development was still ongoing
Close collaboration with project stakeholders to ensure constructability and design feasibility

[Environmental Responsibility]

Managing construction within a sensitive waterway environment

Construction works were delivered within a site located at the confluence of three waterways. Environmental controls were implemented throughout the project to manage site access, protect surrounding waterways, and ensure safe delivery of the enabling infrastructure.
