Make irrigation repairs easier with an IWDD
An IWDD is a county special taxing district that’s managed by you and your neighbors. An IWDD helps with funds to cover the cost of irrigation system upkeep, helping you stay on top of repairs. An IWDD also makes sure costs are shared equally by neighbors.

How to start an IWDD
Once you and your neighbors agree to form an IWDD, follow the steps below to start the process with the county.
First, decide which houses will fall within the boundaries of the group. An IWDD can only be formed if "50% plus one" of individual homeowners within your proposed boundary vote to approve.
Next, you’ll need to do some paperwork. Write and submit an impact statement, a request for resolution and a petition to Maricopa County.
Finally, establish leaders and rules. You and your neighbors will elect trustees to govern the IWDD and, together, establish the bylaws.
How does an IWDD work?
Curious how an IWDD will work in your neighborhood? Here’s a quick overview to help you understand if it’s the right move.
- You choose who leads. Trustees are elected by you and your neighbors and can have different roles based on your IWDD's needs and bylaws.
- You set the rules. You and your neighbors establish the bylaws based on the needs of your private irrigation system.
- You’ll meet annually. Unless your bylaws state otherwise, trustees hold an open annual meeting to discuss budget needs for the next year, file necessary paperwork and schedule maintenance.
- Funds come from your property taxes. They’re collected each year through your Maricopa County property assessments, and 100% of the funds collected remain with the IWDD.
Explore the costs and benefits
Your IWDD trustees not only collect funds, they also coordinate maintenance and repairs to the private neighborhood system in a timely manner. Other benefits of an IWDD include:
- Establishes an account with the Maricopa County Treasury to save and pay for current and future irrigation expenses.
- Creates an equitable way to share the cost to repair and maintain private irrigation systems.
- Eliminates the task of collecting funds door-to-door.
- Establishes fair and transparent rules for how funds are spent.
- A well-maintained private irrigation system allows irrigation to flow efficiently protecting our water resource.
Costs are determined by your IWDD annual budget, which is divided by the number of acres within your IWDD. In 2022, the annual average costs for a homeowner with a 0.25 acre property was $61.01.
