Irrigation and Landscape Plan Submittal Requirements

In order to extend the yield of Denver Water’s water supply and to encourage the efficient use of water, the irrigation of landscape of more than one acre is subject to special review.

Note: All taps to 24-inch and larger water mains will be estimated and installed by Denver Water crews at the developer’s expense.

If the proposed tap size is 3 inches or larger, Denver Water will require a separate Water Plan Submittal.

Irrigation/Landscape Designer submits the following:

  1. Transmittal letter with contact person’s name, phone number and email address
  2. PDF document Irrigation Plan Review Checklist
  3. One 24" x 36" size drawing Irrigation/Landscape Plans and Details
  4. AutoCAD files with individual DWFs of the plan set
  5. Excel document Projected Annual Water Budget (insert zero for acres under plant material not used in the budget)

*********** $450.00 Review Fee required on ALL subsequent submittals ************

If nonpotable water is being considered for irrigation purposes, a user plan to comply must be submitted and approved by the Colorado Department of Public Health and Environment before Denver Water will approve the plans and install a tap. Expect at least six months processing time for the Colorado Department of Public Health and Environment to review and approve the plan.
