The fine bubble membrane diffuser system is to include all necessary below-water elements, including fine bubble diffusers, diffuser holders, air distribution pipework, air release systems, manifolds and drop-legs. Standard efficiency fine bubble membrane diffuser systems will have a standard oxygen transfer efficiency (SOTE) in the range of 6 %-7 % per metre depth of submergence. High efficiency fine bubble membrane diffuser systems will have a standard oxygen transfer efficiency (SOTE) in the range of 7 %-9 % per metre depth of submergence. The service provider(s) will offer a complete end-to-end service solution including the supply of all technical labour needed for the design, supply, installation and commissioning of complete FBMD and aeration systems. For single, large scale requirements, the service provider(s) may be required to ‘project manage’ to ensure that all goods are supplied in a timely manner, and to minimise project costs. New aeration growth schemes are typically delivered by our alliance partners, and the service provider(s) for this lot of the agreement will be expected to work collaboratively with our alliance partners to deliver the most efficient and cost effective technical solutions. Thames Water reserve the right to use alternative technical labour for the installation and commissioning works, and where alternative technical labour is to be used, these labour resources will be sourced from the service provider(s) awarded lot 3 of this agreement.
