Slamannan Waste Water Treatment Works: Secondary Treatment Plant in Falkirk, Scotland

Slamannan Waste Water Treatment Works is a municipal wastewater facility located on Balmulzier Road in Slamannan, Falkirk, within the Alba/Scotland region of the United Kingdom. The plant serves a population of approximately 1,574 people, classifying it as a small agglomeration under Scottish water regulations. The facility provides secondary treatment, which is the standard level required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for freshwater discharges from agglomerations of this size. The plant has a designed capacity of 1,933.00 cubic meters per day and currently discharges an average of 350.43 cubic meters per day, indicating operational headroom. The treated effluent is discharged into a local watercourse that ultimately drains into the Firth of Forth, a major estuary on Scotland's east coast. The plant plays a key role in protecting the water quality of the Forth catchment, which supports diverse aquatic life and is important for both conservation and recreation.

The plant discharges into a tributary of the River Avon (Falkirk), which flows into the Firth of Forth, a large estuary that connects to the North Sea. The Firth of Forth is an ecologically sensitive area supporting diverse bird populations, fish species, and marine habitats. The secondary treatment provided helps reduce nutrient and organic loads, protecting downstream water quality in this important coastal ecosystem.
