Development Fees


Plan Review Fees (covers master plan and design review fees, including hydraulic modeling and administrative costs)


The first submittal of the master water plan for review shall include two (2) copies of the plan containing elements as outlined on the Master Water Plan Checklist.  Any subsequent submittals of the master water plan for review shall include only one (1) copy.  A Master Plan is required for phased projects, complex projects, projects that require off-site infrastructure, or other projects as deemed necessary by the District.


The first submittal of the water design plan for review shall include two (2) copies of the plan containing elements as outlined on the Water Plan Review Checklist, one (1) copy of the paving/sewer plans (if applicable), one (1) copy of the grading and drainage plans showing topographic information along the water line alignment, and one (1) copy of the landscape plans.  Subsequent submittals shall include only one (1) copy of the water improvement plans.  Legal descriptions and drawings for public water easements should accompany a subsequent submittal, or after alignments have been determined.


All plan submittals shall include:

  • Copy of the Plan Review Fee form, filled out with applicable fees (project number is assigned during the first submittal).
  • Copies of materials as specified above for the type of submittal.

Plan Approval

When plan review is complete, one (1) – 4 mil reverse-read double-matte mylar original (retained by MDWID after signing) shall be submitted with the appropriate right-of-way and fire jurisdiction approvals/signatures (when applicable) to be signed by the MDWID.  An electronic copy in in PDF and CAD shall also be submitted. A scanned version of the approved plans will be returned to the consultant.

Plan Revision or Re-Approval Fees (covers fees for each plan revision or re-approval)


For formal plan revisions after plan approval or during construction, applicable revision plan sheet(s) are to be submitted electronically in PDF to Engineering staff for an expedited review.  Once receiving approval, the revised plan sheet(s) shall be submitted in mylar, to be initialed/dated by the District Engineer, and copied for distribution to the field.  An electronic scan of the approved revision will also be sent to the consultant. Whether a change to the approved plan constitutes a formal revision or simply a red-line change is at the discretion of the District Engineer.


Water design plans that expire one year after an approval (if no construction permit is issued), are eligible for a one-time re-approval upon request of the original consultant. Staff will make the approved mylar on file available to the consultant to be manually updated with a new signature block for re-approval signatures. If no construction permit is issued within two years of the original approval, a new submittal with associated fees is required.


Any plan revision or re-approval shall include a completed Plan Review Fee form with the applicable fees.



Inspection Fees (covers fees for infrastructure and backflow inspection, and are due at time of water construction permit issuance)

Payment of Inspection Fees shall include:

  • Copy of the completed Inspection Fee form.
  • Attached copy of the contractor's bid for construction of the public water portion of the project (exclude private portion of the water service and fire service work)
  • Infrastructure Inspection Fees - 2.5% of the construction cost for the public system (water mains, fire hydrants and water services up to the meter and excluding private fire services after the public valve).
  • Backflow Inspection Fees - $110 per backflow device (non-residential and irrigation meters only, unless residence is tied-into an alternate well source).

Protected Facilities Fees (covers fees for connection to protected facilities, when applicable, and are also due at the time of water construction permit issuance)

Fire Flow Impact Fees - The District has established impact fees for the La Cholla Corridor area and the Cortaro Farms Road Corridor area to ensure that adequate fire flow exists in those localities. The District financed system development improvements in the La Cholla Corridor and Cortaro Farms Road Corridor. It will recover its cost as developers of vacant parcels within the impact areas are required to pay the impact fees. Developers have been positive about the establishment of such an impact fee because development could not occur without adequate fire flow. This impact program helped finance the new Magee/La Cholla Reservoir and a 12" water main along Cortaro Farms Road.  Fire Flow Impact Fees are based on gross acreage and land use (commercial, multi-family, or residential), and will be included on the coversheet of water improvement plans, if applicable.  See MDWID Resolution 1994-8 or MDWID Resolution 1996-6.

Payment of Protected Facilities Fees shall include:


Water Service Connection Fees - All Service Areas (to establish water meter connections, due when application is made for a meter):

The District charges a water service connection fee to all new customers purchasing a meter or connecting to the system. This includes a meter fee, a water resource fee, and a system development fee. For a standard single family residential home, the total connection fee cost for a standard 5/8-inch meter is $2,372.05.

Note: Installation of a given meter size, per the Water Service Connection Fees above, assumes a water service line exists either equaling or exceeding the size meter desired.  If a water service line does not exist for a meter, or is of smaller diameter than the desired meter size, a new water service line will need to be installed.  All costs for installation of a new or larger water service line are the customer's responsibility.  The customer is also responsible for all work to construct or connect the private side, from the water meter to the house or structure.

Meter Fee - The meter fee represents the cost of materials and labor to purchase and install a given meter size.

Water Resource Fee - The water resource fee is intended to have new development contribute to the acquisition of the District's water allocation to meet current and future needs. These fees equate to how much the District anticipates the added capacity will cost for additional Central Arizona Project water allocation per acre foot for the holding and capital costs..

System Development Fee - The District was the first water provider in the region as well as one of the first public entities to require developers to contribute to infrastructure upgrades associated with growth through the payment of a system development fee. The Board has maintained a policy of not having growth negatively affect existing customers' needs; and thus, supports the system development fees.

Fees for Upsizing and Downsizing MetersA meter is either upsized or downsized when it is determined either more or less capacity is necessary (e.g. more capacity for a combination domestic and private fire sprinkler system), or to switch to a meter size that is the more cost-effective for current or intended usage.

Fees for upsizing or downsizing meters shall adhere to the following:

Upsizing Fee – the difference in the Total Fee between the sizes listed in the Water Service Connection Fee schedule (above), for the added capacity of the larger meter.

Downsizing Fee – the Meter Fee listed in the Water Service Connection Fee schedule of size meter desired (above), for the materials and labor on the new replacement meter.

Note:  Upsizing a meter assumes the water service line feeding the meter is a least as large as the size meter desired.  If this is not the case, a larger water service line will need to also be installed prior to the upsizing of the meter.  All costs for installation of a new or larger water service line would be the customer's responsibility, as well as reconnection of the private system after upsizing or downsizing of the meter occurs.

Metro Water increased its storage capacity of 4.5 million gallons in 1992 to over 16.5 million gallons in 2008. More storage increases overall reliability... More>
