ALFORD WWTP - Secondary Treatment Plant in Alford, Aberdeenshire, Scotland

ALFORD WWTP is a municipal wastewater treatment facility located in Alford, Aberdeenshire, Scotland. It serves a population of approximately 2,779 people, classifying it as a small agglomeration under Scottish water regulations. The plant is situated inland, more than 10 km from the coast, and its operations are part of the broader water infrastructure managed by Scottish Water. The plant 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 designed capacity of 3,250 m³/day allows for a reasonable buffer above the current discharge volume of 618.70 m³/day, indicating adequate headroom for future growth. As a Scottish facility, it operates under the regulatory framework of the Scottish Environment Protection Agency (SEPA), which issues permits and monitors compliance with environmental standards. The treated effluent is discharged into a local watercourse that ultimately drains into the River Don, which flows eastward through Aberdeenshire to the North Sea. This river supports diverse aquatic life, including Atlantic salmon and brown trout, making the plant's treatment performance important for maintaining downstream water quality and ecosystem health.

ALFORD WWTP discharges into a tributary of the River Don, which flows through Aberdeenshire and enters the North Sea at Aberdeen. The River Don is a key habitat for Atlantic salmon and supports a variety of freshwater species. The plant's secondary treatment helps protect this riverine ecosystem from nutrient pollution and organic loading, contributing to the overall health of the North Sea coastal environment.
