The works involved full visual inspection and GPS location of exposed pipework, safe excavation and spoil disposal, and surface preparation for testing. Ground pipework and valves were installed to AAVs and Manual Air Bleed Valves with concrete slabs and protective infrastructure. Existing coatings were removed under specialist asbestos supervision, pipework was re-wrapped to TS 18, PAUT testing was completed, and all areas were reinstated in accordance with SA Water Standards.
