CP276  Private Sewers and Lateral Drains - Inspection, Cleaning and Renovation Sewerage
The consensus of opinion at the January 2005 DEFRA seminar "Review of existing private sewers in England and Wales: What Next?" was that private sewer / lateral drain ownership will shift from householders to Sewerage Undertakers as early as 2006, substantially increasing volumes of small diameter sewerage assets owned by Utilities.

These assets may have been built to lower standards than public sewers, and are often shallowly laid and hence susceptible to damage. In taking over ownership, Utilities need to identify cost effective methods for inspection, cleaning and repair. A well-established market for these services exists involving insurers, property owners, local Government and drain repair companies, but little independent research is available on techniques and costs. Such knowledge would underpin Utility decision-making on procurement / capital / operational policies. These techniques for small diameter drains may also be important in reducing groundwater infiltration / exfiltration in sewer networks.

After asset handover, fitting demarcation chambers on property boundaries may be particularly necessary for troublesome laterals / sewers, to facilitate inspection cleaning and repair. Including these chambers will complete the analysis of available solutions.

This project will produce a comprehensive reference on survey, cleaning and repair options to support the transfer of ownership of private sewers and lateral drains.

Benefits

  • Identification of rehabilitation options to support policy decisions / responsibilities for Utilities and insurers in operating small diameter sewers and lateral drains
  • Confidence in selecting survey, cleaning and repair technologies to cost-effectively maintain serviceability of the extended network and to tackle infiltration / exfiltration
  • More effective operational and procurement policy through transference of existing market experience on drain survey, cleaning and repair.
