LLANBEDR STW - Secondary Wastewater Treatment Plant in Llanbedr, Gwynedd, Wales

LLANBEDR STW is a wastewater treatment plant located in Llanbedr, Gwynedd, Wales, serving a population of approximately 2,660. The plant provides secondary treatment, which is the standard level required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for discharges into coastal waters. As a small agglomeration, it meets the regulatory expectations for its scale. The plant's designed capacity is 2,660 population equivalent, with a reported discharge volume of 592.21 cubic meters per day. It is situated within 10 km of the coast, indicating that treated effluent likely discharges into coastal waters or a nearby river system that flows into Cardigan Bay. The plant operates under the UK's environmental permitting regime, which transposes the EU directive's requirements. The receiving waters ultimately drain into Cardigan Bay, part of the Irish Sea, which supports diverse marine life including seabird colonies and cetaceans. The plant's secondary treatment helps protect this sensitive coastal ecosystem from nutrient pollution and pathogens.

LLANBEDR STW discharges into the local catchment that drains to Cardigan Bay, a marine area in the Irish Sea. The bay supports diverse aquatic life, including important fish spawning grounds and migratory bird populations. Secondary treatment reduces organic load and suspended solids, helping maintain water quality in this ecologically sensitive coastal environment.
