High Bentham STW discharges into the River Wenning, a tributary of the River Lune, which flows into Morecambe Bay, a large estuary on the Irish Sea. The River Lune catchment supports salmonid fisheries and diverse aquatic habitats. Morecambe Bay is an ecologically sensitive area with extensive mudflats and saltmarshes that provide feeding grounds for wading birds and wildfowl. Secondary treatment reduces biochemical oxygen demand and suspended solids, helping to maintain water quality in this important river-to-estuary system.
