Plan Reviews

When is a Plan Review required?

Denver Water requires that all planned construction, involving installation of a pipe 3-inch and larger, must be reviewed and approved prior to construction. Plan Review includes, but is not limited to:

  • Main extensions for new development
  • Fire hydrants
  • Fire sprinklers and domestic connections 3-inch and larger. All 2-inch and smaller taps should be included in the overall plan. However, if the project consists of only 2-inch and smaller taps, a Plan Review is not required.
  • Water line relocations or modifications

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. Any deviation from these standards will result in plan rejection.
