Project Title Relining Suction Line Netherby Street Corowa

⁠⁠⁠Overview

Federation Council is seeking to engage a suitably qualified and experienced contractor to reline the raw water suction main at the Netherby Street Pump Station, located off Lone Pine Avenue in Corowa. The existing 425mm cast iron suction line, dating back to the original 1923 and 1946 installations, is currently showing signs of leakage and requires relining to restore structural integrity and prevent pump cavitation.

Scope

The scope includes:

• Mechanical disassembly of the existing pipework
• Descaling of the suction line in preparation for relining
• Installation of a specialised vacuum-rated structural liner

Contractor Requirements

• Suitably qualified and experienced in relining suction mains and similar water infrastructure
• Capable of providing a high-level engineering solution that ensures a 30-year service life, given the asset operates under negative pressure and is located within a deep dry well and river-intake tunnel
• Capable of undertaking craneage and confined space operations within the critical tolerances required by the existing infrastructure

Site Inspection

A mandatory site inspection is required prior to quote submission to verify site access, internal pipe configurations and lifting corridors, due to the age of the infrastructure and the critical tolerances required for craneage and confined space operations.
