Design and Construction Eastern Force Main Stage 1 Renewals

⁠⁠⁠Overview

The City of Gold Coast called for a Registration of Interest for the design and construction of renewals to Stage 1 of the Eastern Force Main.

About

The Eastern Western Force Main (EWFM) is a critical sewerage conveyance asset that collects and transports wastewater from the Benowa Re-Pump Facility to the Coombabah Sewage Treatment Plant. The asset is over 30 km in length and crosses major road corridors, residential streets, and multiple waterways, as well as environmentally sensitive areas. Sections of the EWFM are in poor condition and currently pose an unacceptable operational and environmental risk.

Purpose

To accommodate forecast population growth within the catchment, and in response to significant planned infrastructure works in the area, the City is required to meet its General Environmental Duty (GED) obligations. Accordingly, upgrades to the sewerage network are required.

Scope

The scope includes:

• Replacement of sections of the existing Eastern Force Main where the current alignment conflicts with a major infrastructure project planned for FY27
• Upsizing the main along a new alignment to provide capacity for future population growth and adjacent infrastructure development
• Addressing existing high-risk sections of the network that are constrained under current demand
