In the OJEU documentation for the contracts Scottish Water said a significant portion of the waste water partners work would be 鈥渋n connection with projects intended to remove properties from the flood register by addressing flooding resulting from overloaded sewers and also to address unsatisfactory intermittent discharges from the sewer network鈥.

While, it said the water partner鈥檚 work would centre around projects to 鈥渞ehabilitate鈥 the water mains to decrease risk of leaks and other problems.

The waste water partner contract is estimated to be worth 拢360m between 2015 and 2021, and would be worth the same again if extended for the next regulatory period.

The water infrastructure partner job is valued at 拢375m over the initial six year period and a further 拢375m if extended over the second period of six years.

Both partners will be expected to undertake some initial work ahead of the start of the first regulatory period in 2015.
