Non-Infrastructure Medium Project Work

Non-infrastructure MEICA and Civils ~ Medium (RW1) Project Work. TWUL are procuring delivery capability for Non-Infrastructure projects.

TWUL recognises non-infrastructure as nominally all above ground plant, equipment, structures and process; the expected scope of works spans Thames Water's water and wastewater non-infrastructure (treatment) assets across the Thames Water region. The Non-infrastructure scope includes refurbishment, replacement and provision of new potable water and wastewater treatment assets including service and storage reservoirs

Water non infrastructure scope includes but is not limited to:

• refurbishment, replacement and provision of new potable ground and surface water production assets such as enhanced slow sand filter performance,
• disinfection,
• surge protection,
• chemical dosing,
• supervisory control and data acquisition (SCADA),
• run-to-waste facilities,
• cartridge filters and UV,
• increased power resilience,
• inspection and maintenance of existing service and storage reservoirs.

Wastewater non-infrastructure scope includes but is not limited to:

• refurbishment, replacement and provision of new treatment facilities such as inlet works,
• storm water storage,
• event duration monitors,
• settlement tanks,
• biological treatment, tertiary treatment, sludge treatment including thermal hydrolysis process (THP),
• digester roof replacement,
• combined heat and power (CHP),
• chemical dosing,
• phosphorous removal,
• odour control,
• SCADA,
• increased power resilience.
