Thames Water has outlined details of its tender plans for £2.6bn of work under the next AMP7 spending programme.

The big water company will set out further details at a bidders day next month ahead of formally issuing invitations to tender for various lots over the next 12 months.

Thames Water’s draft AMP7 plan includes a number of complex projects, significant programmes and anticipates a potential increased volume in maintenance activity.

Its investment plan covering 2020-2025 will include two major sewage treatment works projects worth together around £180m.

This includes a new treatment works at Guildford and upgrading Mogden sewage treatment works.

Thames Water’s business plan is still provisional and needs to be signed off by regulator Ofwat in December.
