Indication of Available Capacity
This register provides an indication of available wastewater treatment capacity based on loads received in 2021 and available treatment plan capacity now or by completion of a project by 2024 (where relevant).
• Green = spare capacity available.
• Amber = potential spare capacity to be considered on case by case basis.
• Red = no spare capacity available at present.
WWTP Project Planned/Underway
Project planned or underway to increase capacity and/ or improve treatment performance, based on available information in June 2022.
General notes
- The indication of available treatment capacity has been determined based on a standardised national review of the available information.
- The information in this register is subject to change.
- This register provides commentary on the available capacity at the WWTP, it does not consider the capacity of the sewer network.
