Description

The Contracting Authority is seeking to establish a multi-supplier Framework Agreement for the provision of Membrane Aerated Biofilm Reactor (MABR) systems and associated services to support the delivery of its AMP8 Activated Sludge Plant (ASP) Intensification Programme and wider Net Zero Investment Programme.

The Framework Agreement will be used to procure MABR solutions for wastewater treatment assets across the STW region and may be utilised for both current and future requirements throughout the term of the Framework.

The scope of the Framework may include:

  • Design support; and
  • Manufacture and supply of MABR solutions;

The current anticipated portfolio comprises approximately 11 wastewater treatment sites, however, this is indicative only. The Contracting Authority reserves the right to add, remove or amend requirements during the term of the Framework Agreement and may utilise the Framework for additional MABR opportunities associated with future AMP8 and AMP9 investment programmes.

The Framework Agreement will be established for an initial term of four (4) years, with options to extend in accordance with the Framework Agreement. No guarantee of work, volume, value or future Call-Off opportunities is provided.
