2020 Palos Verdes Waterline Replacement Project

The typical events occurring during waterline replacement construction are as follows:

  • Set-up traffic control for the safety of workers, 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 water services from homes from the old waterline to the new waterline
  • Open the street to traffic before moving on to the next section of pipe replacement
  • The contractor will be 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

Neighborhood Impacts During Construction

  • Noise
  • Contractors communicating, operating equipment and vehicles, backup beepers, etc. all generate more noise than typical. The back-up beepers are usually the most noticeable noise – these are required for worker and resident safety
  • Unplanned Service Outages (includes water, gas, electric, internet, and phone)
  • The contractor takes great care not to damage existing utilities, but sometimes utilities owners do not locate their existing utility in the dig area effectively (including Southgate).  Hitting an existing utility with the excavator will typically result in a service outage.  Note that these outages may not be reported to residents directly.  Call Southgate’s office for updates on unplanned service outages. 
  • Road and Sidewalk Closures
  • 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 on your street
  • Access to driveways may be temporarily impacted while the contractor installs pipe in front of the driveway
  • Please mind the “No-Parking” zones – ignoring no parking zones could result in towed vehicles
  • For your safety, avoid the active construction areas and do not walk through construction zones
  • Increased Traffic
  • From the contractor executing work, inspectors making site visits, and detoured drivers to avoid construction zones
  • Construction Materials Stored in the Streets
  • The contractor will have materials temporarily stored in the streets, such as dirt piles and pipe, in anticipation of using the materials for construction
  •  Messiness
  • The streets will get messy with construction – the contractor will keep the streets and sidewalks as tidy as possible as they move through the project area
  • At the end of the project, the contractor will do one big final cleaning of all the streets and sidewalks
  • Paving
  • At the end of the project, the contractor will pave the half of the street in which the waterline was replaced – this is in accordance with City of Centennial standards

Notifications for Property Owners

  • 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 – You will not get a notification if it was unplanned
  • Safety situations can arise or planned water shut-offs turn into an emergency situation and last longer than expected
  • An existing water pipe starts to leak or is damaged and water will be shut-off to repair the water pipe
  • 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

Water Quality

Turning on and off the water system can sometimes disturb accumulated sediment, or cause cloudiness from air bubbles. If this occurs, we ask to do the following:

  • Open the cold-water faucet in the bathtub all the way open, full force, with the drain open, for about 15 minutes. Most dirty water situations will clear up in this time. If not, turn the water off, wait 10 to 15 minutes, and repeat the flushing again.
  • After doing this and the water does not clear, please call us at (303) 779-0261, option 8 to be connected to the on-call operator and report the problem. We can perform additional flushing at our hydrants and blow-off valves near the home.

Emergencies (Water Leak or Sewer Spill)
