CP054  Pollution Prevention & Control in Sewer Systems Sewerage
This project, undertaken by WRc for a group of water utilities, developed practical solutions to manage sewer systems in emergencies, enabling sewage escapes and spills to be avoided where possible. The objectives of the work were to:

  • Assess sewer operational practice and to identify areas where guidance/better information is required to avoid failures developing into pollution incidents
  • Identify appropriate levels of response to an emergency and to optimise systems for dealing with incidents including: call handling procedures, the production of contingency plans and effective information management systems
  • To develop standard procedures for sewer operators with operational failures including first time guidance regarding microbiological contamination die off periods for ground/buildings contaminated with sewage.

Benefits

  • Practical solutions for managing sewer systems in emergencies, enabling sewage escapes and spills to be avoided where possible
  • When failures are inevitable, strategies are recommended to minimise impacts and to demonstrate to the regulators that appropriate actions were taken.
  • Less risk of failures and lower costs if failure does occur.
