Construction of Fish River Steel Pipeline
State Water Corporation
Construction of 0.66 km long steel OD 914 – RRJ pipeline, 2.5 km long steel OD762 – RRJ pipeline, 0.6 km long steel OD762 welded pipeline, Scour valves, air valves and isolation valves, cross connections to Stage 1 and 3 pipelines (at two locations), Valve pits, thrust blocks, anchor blocks, supports, trench stops and bulkhead, end connection of new pipelines to existing Stage 2 pipeline (at four locations), 3 creek crossings. Pipeline grades exceeding 45%.
Working next to a high-pressure, live water main presented challenges to the project, as did the fragile ecosystem which was managed with erosion control measures and silt fencing as outlined in the construction environmental management plan.
Twenty six full days were lost to wet weather but the project was brought in on time and in budget.
