Thames Water has gone out to tender with an AMP7 contract for the design and installation of event duration monitors and flow monitoring at its Sewage Treatment Works sites worth an estimated £18 million.

Thames Water Mogden Sewage Treatment Works

The water company is looking for suppliers to provide MCERTS Event Duration Monitors (EDMs) (U_MON3 driver) to detect start and stop times of overflows to storm tanks, off-line storage, on-line storage, land treatment area or direct to the environment.

The tender also covers the provision of MCERTS pass forward flow (PFF) monitors (U_MON4 Driver) and MCERTS flow monitoring for the first time flow (U_MON5) where the permitted DWF or maximum daily flow is greater than 50m3/d at sewage treatment works (STWs).

The solutions can involve the condition assessment and modification of pre-existing installations to meet the MCERTS standard, or the first-time installation of PFF instruments.

Installations may require a degree of civils work as part of the installation, including new flume channel or wash out chambers.

Initial contract term is 4 years, with four further annual extension options.

Time limit for receipt of expressions of interest is 31st March 2021 – click here to access the tender documentation.
