Water and sewer utility locates refer to the process of identifying and marking the underground water and sewer infrastructure, including pipes, valves, and manholes, to prevent accidental damage during construction or excavation activities. District staff only locate water and sewer lines that are owned and maintained by the district. The district does not mark private utilities, such as customer-owned water and sewer lines on private property.

The district has three days to respond to locate tickets that are generated through Colorado 811. Locate tickets can be submitted by homeowners that are completing jobs as small as installing a new mailbox or garden. Locates performed throughout the entire neighborhood are submitted by contractors that plan to excavate in the area.

Direct Link is currently installing fiber internet within district boundaries, which has resulted in an excess of locates in and around your neighborhood. If you have questions regarding the fiber internet installation, please contact Direct Link at 720-851-1111.

The American Public Works Association (APWA) has established a color code system for utility markings. Water lines are marked in blue, while sewer lines are marked in green. These color codes help workers easily identify the type of utility they are encountering.

The following colors for underground facilities are used:

  • RED – Electric Power Lines, Cables, Conduit and Lighting Cables
  • YELLOW – Gas, Oil, Steam, Petroleum or Gaseous Materials
  • ORANGE – Communication, Alarm or Signal Lines, Cables or Conduit
  • BLUE – Potable Water
  • PURPLE – Reclaimed Water, Irrigation and Slurry Lines
  • GREEN – Sewers and Drain Lines
  • WHITE – Proposed Excavation
  • PINK – Temporary Survey Markings
