Wastewater Treatment Plants - You Can’T Switch Them Off For Repairs

This paper discusses the challenges of undertaking major maintenance and repairs (R&M) on wastewater treatment plants (WWTPs). WWTP’s operate 24 hours a day, seven days a week, 365 days of the year with no off season for undertaking R&M. Repairs and maintenance may not have been fully considered during the design. Furthermore later upgrades may have altered how maintenance and repairs can carried out or reduced the amount of redundancy originally built into the plant.
