Swansea Treatment Works

Aqueous, Oil & Effluent Treatment Facilities

Opened in 2025, our innovative Aqueous Treatment Plant is designed to process a wide range of inorganic waste streams. At its core are two high-capacity reactor vessels capable of safely neutralising most acid and alkali mixtures. Following treatment, a 50-plate filter press is used to dewater the waste and remove neutralised metals, ensuring efficient and compliant waste handling.

Opened in 2024, our Oil & Water Treatment Plant treats contaminated organic wastes, typically with oil or as non-hazardous effluents or spills.

The final stage of our treatment process is managed by the Effluent Treatment Plant, which handles treated water from both the Aqueous Plant and site-wide rainwater collection. This system ensures all discharges meet the strict limits set by our environmental permit and Dŵr Cymru Welsh Water.
