CP076  Installing Telecommunication Ducts / Cables in Sewers Sewerage
Installing fibre optic cables within sewers, to carry broadband telecommunication and data traffic, provides a means for Water Utilities to exploit their assets, providing additional revenue streams. Concerns had been raised whether installing fibre optic cables and ducts increases the risk of blockage and maintenance and affects asset condition. WRc, in collaboration with two water utilities, carried out an objective assessment of the impact of these technologies by:

  • Examining available technologies for man-entry size sewers down to 100mm diameter against structural and hydraulic design, material, size, grading and operational/maintenance criteria of sewers
  • Investigating and collating international research conducted on these systems
  • Developing a framework for appraising systems so new technologies can be examined objectively against issues relating to asset owners and operators.

Benefits

  • Minimise risk when installing fibre optic ducts or cables within sewers
  • Assess the potential impact on the asset condition and the operation and maintenance of the sewers
  • Give Engineers a greater understanding of the technologies
  • Provide an objective framework for appraising new technologies as they are developed and brought to market.
