Pipe Rehabilitation

The 2015 Denver Water Pipe Rehabilitation Project started April 6. The project has been divided into five phases and work will last from April until October with each phase having different start and end dates. Each phase can last up to three months. Keep checking this page for updated information on phases and start dates.

As part of ongoing efforts to provide a reliable, high-quality water supply, Denver Water identifies sections of pipeline to recondition each summer. In 2015, pipe rehabilitation work will improve a total of 51,000 feet of pipeline in four Denver neighborhoods (South Park Hill, Skyland, North Park Hill and City Park West).

Like many other utilities, Denver Water used to install pipelines made of cast iron. Over time, cast iron can corrode and may lead to water discoloration, decreased pressure and increased susceptibility to leaks or main breaks.

Despite these issues, cast iron is very sturdy and — with proper maintenance and improvements — can provide reliable service for decades to come.

This routine, annual project involves cleaning the insides of pipelines and applying a new lining as a cost-effective, minimally invasive alternative to pipe replacement. The new lining protects pipes against future interior corrosion and creates a barrier against leakage, adding many more years to pipes’ ability to provide high-quality water supplies and adequate flows for fire protection. The pipes being rehabbed this year were installed in the late 1800s and early 1900s.

Because water cannot be running in pipes during cleaning and relining, crews temporarily reroute — or bypass — water to customers by setting up above-ground water supply systems of hoses and piping along streets and sidewalks. These work areas may include traffic lane and street parking closures as well as metal covers on temporary street openings.

Pedestrians should take extra caution as there will be temporary above-ground systems of pipes and hoses along the gutters and sidewalks. Additionally, motorists, pedestrians and residents can expect to see:

  • Water running in streets for water quality-related flushing.
  • Construction equipment and materials.
  • Metal covers on temporary street openings.
  • Asphalt paving activities.

We understand the inconveniences maintenance projects can bring to neighborhoods and businesses. To help minimize traffic disruptions, Denver Water works closely with local permitting and traffic authorities as well as elected officials’ offices and associations representing businesses and homeowners.
