The Severn to Thames Transfer (STT)
The Severn to Thames Transfer (STT) would transfer water from the North West and Midlands to the South East for use during a drought. This water would come from the River Severn itself, with Severn Trent Water and United Utilities providing additional sources of water if needed. The water would then be moved from the River Severn to the River Thames either by a new pipeline or by a combination of new pipeline and restoring the Cotswold canals.
An illustrative map is below.
The Thames to Affinity Transfer (T2AT)
The Thames to Affinity Transfer (T2AT) would move water by pipeline from the River Thames to Affinity Water once a new source of water (such as SESRO, STT or a new water recycling project in East London) has been developed. Construction would be in two phases, the first up to 2045, with water available once the reservoir in Oxfordshire (SESRO) is built. The second phase would be up to 2050.
An illustrative map is below.
The Thames to Southern Transfer (T2ST)
The Thames to Southern Transfer (T2ST) would move water by pipeline from the River Thames to Southern Water once a new source of water (either SESRO or STT) has been developed. Construction would be up to 2040, with water available once the reservoir in Oxfordshire (SESRO) is built.
