My Department does not have information covering the United Kingdom as a whole. Between 2000 and 2005, North West Water plans to renew or renovate 281 miles of sewer. For England and Wales, the comparable figure is 1,130 miles. Companies plans for 2006 to 2010 will be reviewed as part of the next periodic review of water companies' prices. The condition of sewers is only one of several factors to be taken into account when assessing whether they need to be repaired or replaced.
Various studies are under way to review the basis for future investment.
