Iron Mill Bay WWTW, Crombie, Fife | Scotland Wastewater Treatment Plant

Iron Mill Bay Wastewater Treatment Works (WWTW) is located in Crombie, Fife, Scotland, serving a population of approximately 19,116. The facility is part of the UK's wastewater infrastructure, managed under Scottish Water's operational area. As a medium-sized agglomeration, the plant is expected to meet secondary treatment standards under the Urban Waste Water Treatment (Scotland) Regulations, which transpose the EU Urban Waste Water Treatment Directive. The designed capacity is 1.00 (likely in megalitres per day or equivalent), indicating the plant's scale. The treated effluent discharges into the Firth of Forth, a major estuary on Scotland's east coast. This water body supports diverse marine life and is an important area for seabirds and seals. The plant's location within 50 km of the coast means its discharge contributes to the coastal environment, requiring careful management to protect water quality.

The plant discharges into the Firth of Forth, a large estuary that flows into the North Sea. This estuary supports a rich ecosystem, including migratory fish, seabird colonies, and marine mammals. The area is ecologically sensitive, and the plant's nutrient and pollutant loads are regulated to minimize impact on the coastal and marine environment.
