2018 Waterline Replacement - Project Limits

Construction Phasing:

Although the project area is large and affects many streets, the contractor will work in a phased manner.  The contractor is starting at the intersection of S. Holly Street and E. Maplewood Avenue and working their way east.  They plan on working through the east/west streets first and then the north/south streets.  Schedule updates will be posted on our website throughout the duration of the project at:  http://southgatedistricts.org/240/2018-Water-Replacement-Project    

The typical events occurring during waterline replacement construction looks like:

  • Set-up traffic control for the safety of works, drivers, and pedestrians
  • Dig a trench for a section of waterline to be replaced
  • Install the new waterline
  • Backfill the trench and compact the soil
  • Test the new waterline – we test to make sure it does not leak and that it is clean
  • Fully connect the new waterline to the existing system
  • Transfer homes from the old waterline to the new waterline
  • Open the street to traffic before moving on to the next section of pipe - the contractor will likely come back to pave at a later date (in order to do a lot of the paving at once), but it will be drivable in the meantime
  • Restore disturbed areas to similar conditions as before construction

Traffic Impacts:

  • Lane closures will be required daily with approved traffic plans by City of Centennial
  • Notifications regarding “No-Parking” zones will be posted prior to construction
  • Access to driveways may be temporarily impacted when the contractor installs pipe in front of the driveway

Notifications for Residents:

  • Please check your front door for notifications during construction
  • Contractor is required to notify you before blocking your driveway
  • Contractor is required to notify you at least 24 hours in advance before planned water shut-offs to accommodate:
    • connecting a new waterline to the existing system
    • transferring a home from the old waterline to the new waterline
    • safety of workers in the trench (exposed waterlines that are not shut-off (i.e. pressurized) are unsafe for workers
  • Planned water shut-offs are typically scheduled Monday through Friday, 9 am to 5 pm
  • Sometimes the contractor runs into unforeseen circumstances that results in an unplanned water shut-off
    • Safety situations can arise or planned water shut-offs turn into an emergency situation and last longer than expected
    • If your water is out and you were not expecting it, please call us  
  • Any time water is shut-off, the contractor will work non-stop until water service is restored
