Scottish Water is looking for contractors to deliver between £500m and £800m of works under its ceramic membrane capital investment programme.
The publicly owned utility company published a contract notice on 1 November inviting bids from firms to deliver the new water filtration programme.
Up to five contractors will be appointed to the framework, which is due to run from 2025 until 2033, with a possible extension to 2039.
Included in phase one of the works are construction, commissioning and handover.
Its notice says: “The appointed partner(s) will be required to have capabilities in all these areas or be able to demonstrate how they will acquire these skillsets.
“The supplier will have pan-Scotland capability to deliver this programme. It is expected that the supplier can act as both principal contractor and principal designer in the delivery of this programme.”
Work to be delivered under the framework includes construction of the already-designed Turriff Ceramic Membrane Water Treatment Works in Aberdeenshire.
Other facilities are expected to follow, with successful contractors designing them.
Membrane technology helps filter water in treatment centres. Although often more expensive up front than polymetric versions, ceramic membranes are becoming increasingly popular in water treatment works, as they are seen as having longer lifespans and good thermal stability.
Companies interested in bidding for the work with Scottish Water have until midday on 13 December to submit their tenders.
More information can be found in the contract notice.
