Scope of Work

Design of large diameter water transmission pipeline, two pressure regulating stations, and a metering station with radio telemetry.

Project Challenges

  • Devise solution to localized low pressures in distribution system.
  • Limited accurate record information available for underground utilities.
  • Provide maximum flexibility for use of alternative construction methods.
  • Two adjacent projects being designed concurrently by others and scheduled for construction immediately following the completion of this project.

Solutions and Successes

  • Recommended solutions to low pressure problems using hydraulic model developed by Brelje & Race as part of prior Water System Master Plan work.
  • Developed construction documents to allow use of directional boring or open cut methods.
  • Set-up procedures for quick re-design of vertical alignments as potholing revealed true location of existing utilities.
