As a secondary treatment facility, it provides biological treatment to reduce organic matter and suspended solids before discharge. Under New Zealand's regulatory framework, wastewater treatment plants are governed by the Resource Management Act (RMA) and regional council discharge permits. For a plant of this scale, secondary treatment is standard, and the plant's discharge volume of 278.60 megalitres per year indicates consistent operation. The plant is situated near the coast, which influences its discharge management and environmental considerations. The treated effluent from Weston plant ultimately reaches the Pacific Ocean via local waterways. The coastal environment supports diverse marine life, including fish, seabirds, and invertebrates. The plant's proximity to the coast necessitates careful monitoring to protect water quality and marine ecosystems from nutrient enrichment and other pollutants.

Weston plant discharges into the Pacific Ocean via local streams and groundwater. The coastal waters off Otago support diverse marine ecosystems, including kelp forests, fish, and seabirds. Nutrient inputs from treated wastewater can affect algal growth and water clarity, making effective treatment essential for maintaining ecological balance.
