2021 Big Dry Creek Interceptor (BDCI) Sanitary Sewer Rehabilitation Project Phase I

Please excuse our mess! Our apologies in advance for the annoyance of traffic impacts! Thank you for your patience and cooperation while we rehabilitate critical infrastructure to protect health, safety and the environment in your neighborhood!

Schedule Update (9/30/2021):

Work will commence in late May and is expected to be completed by mid-late October 2021. Rehabilitation work at the O - Line Preserve location as well as the River Point location have been completed. Mobilization effects for the Big Dry Creek/Progress Park location have been delayed. An update will be provided as soon as new information becomes available.


Project Information:

Location
Work is scheduled to occur throughout the District’s service area including within the Cities of Greenwood Village, Sheridan, Englewood and Littleton, Colorado.

DescriptionContractor will rehabilitate approximately 2,900-linear feet of 42” Reinforced Concrete Pipe (RCP) and 400-linear feet of 27” Vitrified Clay Pipe (VCP) sanitary sewer via Cured-In-Place Pipe (CIPP). This will require continuous sewer bypass, cleaning, infiltration stopping, build-back, and rehabilitation of twenty (20) sanitary sewer manholes. Approximately six (6) of the manholes are in roads and require traffic control, and other manholes utilized for temporary bypass pumping may also require traffic control.

The typical events occurring during rehabilitation efforts are as follows:

  • Set-up traffic control for the safety of workers, drivers, and pedestrians
  • Isolate the section of sewerline/manhole to be rehabilitated
  • Clean sewerline
  • Setup bypass system
  • Install Cured-In-Place-Pipe
  • Test the newly rehabilitated sewerline – we test to ensure the lining is installed to established specifications
  • Re-establish existing sewer service connections to the newly rehabilitated sewerline
  • Open the street/area to traffic before moving on to the next section of pipe rehabilitation
  • 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, sewer, 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 the various municipalities mentioned above
  • Notifications regarding “No-Parking” zones will be posted prior to construction on your street
  • Access to driveways may be temporarily impacted while the contractor rehabilitates 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


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:
  • Reconnecting any existing sewer services to the existing system
  • 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 shut-offs turn into an emergency situation and last longer than expected
