SEVERN Trent and Northumbrian Water, along with Yorkshire Water, are also making provisions to pare back their framework contractors.
A Northumbrian spokesman said it will split its workload three ways. Contractors will be appointed to a framework for an initial period of three years with the option to extend for two more.
A main A-list of contractors will take care of Northumbrian's core civils work, estimated at £30 million a year. The authority is expected to appoint between five and eight firms.
A B-list will become the authority's Area Service Providers. The area will be split geographically and a contractor will be appointed to each area to carry out duties such as CCTV installation and sewer cleansing. This is expected to generate up to £20 million worth of work a year.
A C-list will take care of the authority's M&E work, set at £12 million a year. All appointments will be made between January and March.
In September, Severn Trent advertised in the of ficial Journal for firms to prequalif y for its approved contractors lists for pipelines and for waste-water.
It has yet to firm up its plans but one UK-based contractor said Severn Trent is looking to draw up a list of 12 contractors that will bid against each other on a job-to-job basis.
