Supply of Precast Concrete Tank Panels

Severn Trent Water are working on reducing design time, carbon efficiency and construction time for several key assets over the current Asset Management Plan (AMP8). Storage tanks have been identified as an asset used widely across the business, from storm tanks to distribution service reservoirs.

Severn Trent Water have developed a Plug and Play modular precast concrete tank system that can be used in several applications which allow standardisation of assets, reduce costs and improve 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 technical specification details the requirements for the supply of precast concrete panels for the Plug & Play tank solution. 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, demonstrated in the following volumes.

The overall Framework will include a number of different product lines. These are:

1. Above ground square/rectangular tanks
2. Below ground square/rectangular tanks
3. Above ground circular tanks
4. Below ground circular tanks

The first design completed, and included in theis tender document, will be for the product line "Above ground rectangular tanks 6m high". The designs for the remaining product lines are yet to be completed.

As a result, Severn Trent intends to award the initial phase of the Pre-cast Concrete Framework to a single supplier. Only one supplier will be awarded the delivery of these initial phase and will be considered the primary supplier.

As part of this tender process, Severn Trent will also select up to three secondary suppliers.
