The water company is working on reducing design time, carbon efficiency and construction time for several key assets over AMP8; storage tanks have been identified as an asset used widely across the business, from storm tanks to distribution service reservoirs.

Severn Trent Water (STW) has developed a Plug and Play modular precast concrete tank system that can be used in several applications which allows standardisation of assets, reduced costs and improved carbon efficiencies.  and now are looking to develop a supply chain to work with in supplying this asset, both directly as STW and also indirectly through the STW capital supply chain.

The tank solution is intended to be used across both potable drinking water assets and wastewater assets.

It is expected that the split between clean water and wastewater will be unequal; most tank panels will be required for wastewater assets.

The overall Framework will include a number of different product lines as follows:

The first design completed will be for the product line "Above ground rectangular tanks 6m high". The designs for the remaining product lines are yet to be completed.

When Severrn Trent went out to tender it explained that only one supplier would be awarded the delivery of the initial phase and would be considered the primary supplier. As part of the tender process, it would also select up to three secondary suppliers.

The following companies have been awarded a place on the framework:

FLI Precast Solutions UK Ltd

Kilnbridge Structures Ltd

Marshalls Mono Ltd

Shay Murtagh (Precast) Ltd

Earliest date the contract will be signed is 13 April 2026 – current estimated start and end contract dates are 13 April 2026 to 13 April 2028 with further possible extension options up to 13 April 2031.
