Denver Water crews install or replace an average of 60,000 feet of pipe a year. Replacements are done for various reasons, including repairing or avoiding main breaks, replacing corroded pipe, alleviating water quality problems, increasing available hydrant flow and improving area delivery.

The water distribution system contains more than 3,000 miles of water mains. Every improvement and replacement project is different because of the conditions at the project site.

When Denver Water is working in your neighborhood, you will receive a PDF document notice at your door describing the project and providing contact information in case you have questions. To inquire about a specific ongoing project, please contact the project foreman identified on the notice. For other questions, call Denver Water Customer Care at 303-893-2444.

  • Sequence of work

    Pipe replacement projects are done in phases.

    • About a week before the project begins, Denver Water will mark the location of water lines with blue spray paint. A utility locate company will then mark locations of other buried utilities such as natural gas and telecommunication lines.
    • Signs blocking parking spaces will be placed at the work site a couple of days prior to work. Storm water protection materials also will be installed.
    • Before work begins, all plans for the site are approved by the government agency associated with the project's location. 
    • The street will be cut and/or milled.
    • Crews will dig a trench and install the new water main.
    • The new main will be disinfected and pressure–tested. 
    • Crews may be offsite while Denver Water’s water quality experts test samples from the main.
    • After the new main passes these tests, crews will return and connect service lines, fire hydrants and fire lines to the new main.
    • Crews will disconnect the old main.
    • Paving will be done per the requirements of the local government.
    • Any damage to curbs or landscape will be repaired. 
    • Storm water protection materials and parking signs will be removed.
  • Scheduling

    Permanent paving is scheduled after the entire project is complete and may be delayed due to weather or to combine projects into one efficient paving job. Because of this, Denver Water covers all jobs with temporary paving at the end of every day or after repairs are made.

    Water service emergencies, such as a main break in other parts of Denver Water's system, may take precedence over replacement projects. Please be aware that workers may leave at a moment's notice to work on those emergencies and may not return the following day.

  • Service line inspection

    Although service lines are owned by property owners, when Denver Water replaces or repairs a section of our water main, we will test the section of the service line between the water main and the water meter to determine if it is made of lead or galvanized iron. If we find that this section of service line is composed of either lead or galvanized iron, Denver Water will, as a courtesy, replace that section.

    Because lead service lines can increase the exposure to lead through drinking water, Denver Water encourages impacted customers to test andif lead is found replace, at their discretion, the section of service line between the meter and the household plumbing.

  • Possible water discoloration

    After a main replacement, you may see reddish discoloration in your water, which is caused by small amounts of iron compounds flushing out of the system. These iron compounds are not hazardous. You can get rid of the discoloration by running cold water for a few minutes through the bathtub or outside spigot, which don’t have aerators. Iron particles can get caught in your faucet aerators, which will decrease water flow. If that happens, take off the aerator and rinse it out.

  • Landscape restoration

    Denver Water will take detailed photos or videos of hardscape or landscape that may be disturbed during construction. If Denver Water impacts your landscape during construction, we are committed to restoring your landscape to its preconstruction condition. Should your landscape need restoration, we will send you a letter and attempt to call to explain the two restoration options, which are:

    • Restoration payment. Denver Water offers a $2.35-per-square-foot payment for the disturbed landscape of your property. You can expect your restoration payment check to arrive within 10 business days of receiving your response. Once the payment is made, Denver Water will not have further involvement in restoring your property.
    • Landscape restoration. Denver Water will restore your landscape to its preconstruction condition at no cost to you. Note that there may be a planting delay depending on weather and, if needed, to wait for the growing season. We will provide you with guidelines for watering new plantings. After the planting is complete, it will be your responsibility to water and care for the restored landscape plantings.
