LAKELAND IRRIGATION

Water supply infrastructure design for a 10,900 ha irrigation scheme in far north Queensland — Detailed Business Case review.

Project Overview

Lakeland Irrigation Scheme Detailed Business Case

Crucible was engaged to undertake a review of the Detailed Business Case reference design for the pipeline network for the proposed irrigation scheme around Lakelands in far north Queensland.

The scheme included 56km of pipeline mainly in the DN1000–DN1800 size range, a pump station and a new dam. The scheme operated under high static pressure and required extensive pressure control and pressure relief mitigation.

After undertaking the independent review, Crucible provided significant technical input to the finalisation of the reference design, particularly with respect to general risk mitigation for the system and configuration of the pressure management system.

Crucible also provided technical advice to resolve comments raised by the reviewing authority regarding the operational risk profile for the scheme.

High Static Pressure Management

The scheme operated under high static pressure requiring extensive pressure control and pressure relief mitigation across 56km of large-diameter pipeline infrastructure.

Large-Scale Pipeline Network

The pipeline network comprised 56km of DN1000–DN1800 pipelines — one of the largest irrigation pipeline networks in far north Queensland — requiring specialist hydraulic expertise.

Regulatory Risk Resolution

Crucible provided targeted technical advice to resolve comments raised by the reviewing authority regarding the operational risk profile, enabling the project to progress through approval.
