Severn Trent Water (STW) is undertaking a market engagement exercise to inform a future procurement for the design, assembly, supply, delivery and co-commissioning of Membrane Aerated Biofilm Reactor (MABR) systems across approximately 13 wastewater treatment sites. This exercise will inform procurement strategy, scope development and market understanding. Core scope includes design support, manufacture, supply, delivery and co-commissioning of MABR systems. STW is also exploring whether suppliers can undertake additional responsibilities such as detailed design, installation, commissioning, optimisation and maintenance support.
