Plan Reviews

When is a Plan Review required?

Denver Water requires that all projects involving installation of a 3-inch and larger connection must be reviewed and approved prior to construction.

If a project contains any one of the following, a Plan Review is required:

  • Main extensions for new development.
  • Fire hydrants.
  • Fire sprinklers and domestic connections 3-inch and larger.
  • Water line relocations or modifications.

All existing and new 2-inch and smaller taps are required to be included in the overall plan. However, if the project consists of only 2-inch and smaller taps, a Plan Review is not required.

Plans shall be prepared, stamped, and signed by a PE licensed by the State of Colorado. CAD files must meet the requirements and specifications detailed in Denver Water’s CAD Standards External Requirements. Any deviation from these standards will result in plan rejection.


Denver Water’s approval of plans and specifications expires after one year of inactivity
