Source basis

Solomon Water's official institutional pages establish its state-owned utility status and municipal water and wastewater remit. ADB and the utility identify Solomon Water as the implementing and operating-side organization for UWSSSP. The current public record still leaves the proposed NRH and Ranadi marine works at bid-document stage and does not reconcile the later two-outfall geometry with the older three-outfall basis in the corporate plan. The Fisheries-to-Ranadi progress image and contractor record belong to a separate landward sewer section. EIB's related facility excludes the new outfall pump stations and sea outfalls. None of those records proves a marine works award, offshore mobilisation, installed outfall pipe, first discharge or operating acceptance.
