Irrigation and Plan Review Checklist

The irrigation of landscape, more than or equal to 1 acre, whether contiguous or noncontiguous, is subject to special review by Denver Water.

Irrigation Review

The following is a checklist of items required to initiate an irrigation review with Denver Water:

1. Transmittal letter with contact person’s name, phone number and email address.
2. $450 filing fee.
3. One full set of 24” x 36” irrigation/landscape plans, details and irrigation notes (obtain current Denver Water Notes and Details).
4. Water budget.

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.

If the proposed tap size is 3 inches and/or larger, Denver Water requires you to complete a Plan Review Submittal. If tap is 2 inches and/or smaller, a Plan Review Submittal is typically not required. The process mentioned below doesn’t include main extensions, fire line or fire hydrant installations.
