Project Update

Highlands Ranch Small Storm Sewer UV-CIPP Lining Project – UPDATE

Insituform Technologies dba C&L Water Solutions will be conducting UV lining on storm sewer in three (3) locations the week of October 27, 2025.  The following are the three (3) locations, weather, and site condition dependent:

  • Southwest corner of Summit View & Heatherwood: A storm conduit located in the open space at this location. There will be restricted street parking and potential lane impacts on Heatherwood since we are taking access from Heatherwood.
  • 9275 S Broadway: A storm conduit at this location, which is where the Circle K Gas station is. Broadway southbound in the outside lane and the commercial center access point will be affected with lane closures for this work.
  • Northridge Rec Center (8800 S Broadway): A storm conduit is located at this location and is in the open space directly west. Broadway southbound in the outside lane will be affected due to access from the inlet in Broadway and work in the open space.

If additional cleaning is needed, the work may be delayed into next week while they complete the site’s required cleaning tasks.

Description

Highlands Ranch Small Storm Sewer UV-CIPP Lining Project

The Highlands Ranch Small Storm Sewer UV-CIPP Lining projects have started for 2025– Pipe repairs have already been completed located on Plaza Drive (Broadway & Ridgeline) and on Broadway (south of Northridge Recreation Center driveway).  Starting in mid-August to early September of 2025, the next phase of storm sewer maintenance on Sterling Ct, Sterling Dr, Heatherwood Ct, Broadway just south of the Northridge Rec Center Access point, and at 9261 S Broadway, will occur. These projects are anticipated to be completed on December 31, 2025, weather dependent (see map of the area of these locations above or in “Photos” section below).

Storm Pipe Video Inspections 

The 2024-2025 Highlands Ranch subdivision Storm Sewer Pipe Video Inspection Program is ongoing (started in mid-March 2024) and we will be adding 43,500 linear feet (approx. 325 sections) of storm sewer to be inspected. In Highlands Ranch alone, there are approximately 500,000 feet of pipe in existing stormwater systems and cross culverts. The Douglas County Storm Sewer Pipe Video Program began over six years ago, has already completed videos on more than half of these locations, and the remaining locations will continue to be worked on over the next few years.
