How Do I Verify Utilities and Water Access Before Buying in Scottsdale?

Scottsdale utility due diligence: city water and sewer maps, water quality reports, APS versus SRP territory, rate estimators, and what the SPDS must disclose.

September 22, 2026 · 11 min read · Julie Gonzalez

Before you write an offer in Scottsdale, confirm four things in writing: which water and sewer system actually serves the address, which electric utility the address falls under, what the seller lists on the Arizona disclosure form, and what the monthly bill structure looks like at that meter size. Scottsdale City Code requires property owners to extend public water and sewer lines to their property as a condition of receiving service, so "the city serves this area" and "this parcel is connected" are two separate questions. With a median sale price of $889,576 across Scottsdale in September 2026 and 82 days on market, the median time from listing to going under contract, you have room to do this work inside the inspection period rather than after closing.

Utility verification means confirming, from the service provider and from the city itself, exactly who delivers water, sewer, electricity and gas to a specific address, whether the connections physically exist, and what the recurring cost structure is. It is a parcel-level question. City names alone do not establish which utility serves a particular home or business.

Scottsdale's own maps show the water service regions, and the City Code puts line extension on the owner

The City of Scottsdale General Plan 2035 Water Resources Element map divides the city into Northern, Central and Southern Water Service Regions and also shows wastewater service areas and water treatment facilities. That map is the starting point for orientation, not the final answer for a parcel.

The binding detail is in the City Code. Scottsdale City Code requires property owners to extend public water and sewer lines to their property as a condition of receiving service. If a line does not already reach the parcel, the obligation and the cost sit with the owner. The city's water and sewer planning page covers sewer taps, the Line Extension Participation Program, water and fire line extensions, water meter reductions, county water meters, plan submittal steps, fees and permits. Those are the exact items to ask about before you remove an inspection contingency on a parcel where you have not seen a meter.

One Scottsdale-specific wrinkle matters if you are also shopping nearby. Within the Town of Paradise Valley there are four water providers, Berneil Water Company, City of Phoenix Water Services, City of Scottsdale Water Services, and EPCOR Water Company, plus two sewer providers, City of Phoenix Water Services and the Town of Paradise Valley system, which is operated and maintained by the City of Scottsdale. Paradise Valley wastewater service runs through an Intergovernmental Agreement with the City of Scottsdale, with flows going to Scottsdale's Water Campus or through Scottsdale's system to the SROG interceptor and the 91st Avenue Wastewater Treatment Plant. A Scottsdale mailing address does not settle who bills you.

The City of Scottsdale Water Services general and 24 hour emergency number is 480-312-5650.

Scottsdale Water publishes quality reports and a service line inventory you can check by address

Scottsdale Water publishes annual Water Quality Reports and performs hundreds of regular tests against standards set by the Environmental Protection Agency. The 2025 Water Quality Report is available for download. Read it before you write the offer, not after.

The second document to pull is the service line inventory. The EPA Lead and Copper Rule Revisions require all community water systems to complete a material inventory of service lines that provide water to customers. Scottsdale's initial service line inventory was submitted in October 2024 and is available online, though some homes and businesses remain incomplete. A service line is the pipe connecting a home to the water main, and the public side, between the water main and the meter, is owned by the city. To be considered complete, the city must inspect three points along a service line: the public and private side of the meter, and where the service line connects to the structure. The exterior service line connection is inspected by Scottsdale Water or a third-party contractor for the city, and if a lead service connection is found the owner is notified and the city works on replacing the line.

If the address you are buying still shows as incomplete in that inventory, that is a question for your inspection period.

The city's water resource planning documents explain where the supply comes from

Scottsdale's General Plan Water Resources Element describes a water portfolio of surface water from the Salt River Project, which is Salt and Verde River water, and the Central Arizona Project, which is Colorado River water, along with groundwater and reclaimed water. As required by the State of Arizona, Scottsdale has an assured water supply designation ensuring sufficient supplies for the next 100 years before allowing any new development. In 2006 Scottsdale reached safe-yield in groundwater usage, where groundwater recharge exceeds withdrawal.

The 1980 Arizona Groundwater Management Act created the Assured Water Supply Program, which requires a municipal water provider to demonstrate a 100-year Assured Water Supply for existing, committed and future demand through five criteria: physical water availability, continuous availability, legal rights, water quality, and financial capability. Scottsdale is required to maintain its status with the Arizona Department of Water Resources as an Assured Water Supply Provider under state statutes, and the city must demonstrate the ability to deliver a 100-year sustainable water supply in compliance with the program.

One limit is stated plainly by the city: Scottsdale's assured water supply designation applies to the city's population at build out, and it does not account for customers outside its service area. That sentence is the reason a parcel outside the service boundary is a different purchase than a parcel inside it.

City growth projections used in water infrastructure planning estimated Scottsdale's population would increase to 281,700 by 2030. In conjunction with the budget process and based on the most current Water Resources Master Plans, Scottsdale develops and maintains a multi-year Water Resources Financial Plan that is updated annually.

Electric service follows the address, and Scottsdale is split between two utilities

Scottsdale is split between two electric utilities. APS serves the north and the old townsite, while SRP serves most of the south. The city's General Plan electrical map shows SRP serving south Scottsdale from about McDonald Drive and Chaparral Road to the Salt River. Phoenix and Scottsdale are mixed-territory cities, while Goodyear, Peoria, Surprise and Sun City West lean APS for most of their footprint.

A buyer cannot pick between the two. Service follows the address under territorial agreements dating to 1954 and 1955. That makes the governance difference permanent for the life of your ownership: APS is a shareholder-owned utility whose rates are set by the elected Arizona Corporation Commission, while SRP is a public district whose board is elected by landowners, and SRP is exempt from Arizona Corporation Commission jurisdiction.

Three ways to confirm which one serves the house you are considering:

  • Use SRP's address lookup and service territory page at srpnet.com.
  • Use APS's downloadable service area maps at aps.com/en/Residential/Service-Plans/Service-Area-Maps.
  • Look at the top of the first page of the current electric bill, where the utility name appears. Call APS at 602-371-7171 or SRP at 602-236-8888 to confirm.

Ask the seller for a full year of electric bills during the inspection period. Natural gas in Scottsdale houses is supplied under Southwest Gas residential service, and the same request applies there.

Scottsdale water and sewer bills are built from a base charge, a tiered volume charge, and winter water use

Scottsdale's water rate structure consists of a monthly base service charge based on water meter size plus a monthly volume or commodity charge. The base charge represents having water available 24 hours a day, seven days a week, and the larger the meter the larger the reserved capacity. A five-tier increasing block rate structure determines the volume charge for single-family residential accounts, while a four-tier structure is used for multi-family, commercial and industrial, and non-residential irrigation customers.

In the city's water and sewer rate report, the current residential Tier 1 rate, covering 0 to 5,000 gallons, is $1.72 per 1,000 gallons. Tier 2, covering 5,001 to 12,000 gallons, is $3.24, with a proposed $3.39. A utility comparison of eight valley cities along with the proposed impact to an average City of Scottsdale customer appears in the March 3, 2026 Council meeting materials under the proposed FY 2026/27 Rates and Fees agenda item. A State of Arizona water quality assurance fee is added to the total of all water charges.

Sewer works differently, and this is the part buyers miss. Scottsdale states that sewer fees are based on most of a household's winter water use. Under the sewer rate schedule effective July 1, 2024, the monthly wastewater service charge is calculated by multiplying 90% of the customer's average winter consumption for the prior December, January and February by the applicable rate. Single-family residential wastewater rates total $2.97 per unit, made up of operations and maintenance plus capital. All wastewater users also pay a base fee, which is $7.75 for 5/8, 3/4 and 1 inch meters.

To put a number on a specific property, use the city's tools. The City of Scottsdale utilities page offers an Estimate My Bill tool for residential and commercial rates, and the water service page links to separate tools to Estimate Residential Water Rate Charges and Estimate Commercial Water Rate Charges. You need the meter size and a realistic monthly gallon figure to use them, which is another reason to request the seller's billing history. Scottsdale's Solid Waste Division provides trash and recycling collection services in the city, so budget that alongside water and sewer.

After closing, WaterSmart is a free water monitoring portal for all Scottsdale Water customers that lets account holders view usage graphics, use an online leak assistance tool, and download water use data. As of December 2025, approximately 67% of Scottsdale's water customers have access to hourly water use data. About a third of customers do not yet have the infrastructure for hourly data, and the multi-year AMI rollout has an expected completion date of 2030.

The Arizona disclosure form names every utility provider and asks the sewer questions directly

Arizona's legislature has not created a statutory seller disclosure form. The Arizona Association of Realtors drafted the most commonly used one, the Residential Seller's Property Disclosure Statement, known as the SPDS. The standard Residential Real Estate Purchase Contract requires the seller to provide the completed SPDS to the buyer. It is a 10-page form covering six major categories including utilities, and it is due within three days of contract acceptance.

The utilities section requires the seller to list the provider for each utility, including electrical, fuel, cable, internet, phone, garbage, water and fire, and to disclose any known drinking water problems. That is where you compare the seller's stated electric provider against what SRP's and APS's own lookups tell you.

The sewer section is the one to read carefully. It asks whether the entire property is connected to a sewer, whether a professional has verified the sewer connection, and the type of sewer, listed as public, private, or planned and approved but not connected. The form carries a notice to the buyer to contact a professional to conduct a sewer verification test. Sellers must also disclose the type and provider of sewer and the date of the last inspection of the sewer or wastewater system. The SPDS addresses water pressure issues and water heater type, age and condition.

Arizona REALTORS pairs the SPDS with the Residential Seller Disclosure Advisory, which explains that Arizona law requires disclosure of material facts even when nobody asks, and that the obligation survives an agreement that no SPDS will be provided. A seller who declines to complete the form has not eliminated the duty.

During the inspection period, the items worth ordering or confirming in writing are the sewer verification test the form itself points you to, the service line inventory status for the address, and the meter size that drives the monthly base charge.

What the Scottsdale market gives you time for

Across Scottsdale, the median sale price was $889,576 in September 2026, up 9.2% year over year, meaning compared with the same period a year earlier, while the market-time figure increased to 82 days on market from 78 days. The average sale-to-list ratio, the share of asking price a home sells for, was 96.4%, and 29.8% of homes had price drops in the three months ending September 2026.

In a market closing at 96.4% of asking price, assume you will negotiate rather than bid up, and that includes negotiating over anything a sewer verification test or a service line inventory check turns up. Neighborhood pace varies inside the city. In the three months ending September 2026, DC Ranch recorded 60 days on market and Grayhawk 75 days, while Gainey Ranch was at 83 days, Old Town at 85 days, and McCormick Ranch at 95 days. A property in a slower-moving pocket gives you more room to insist on documentation before you release contingencies.

The Bottom Line

Scottsdale utility due diligence comes down to documents you can actually obtain: the General Plan 2035 Water Resources Element map for service regions, the city's water and sewer planning page for line extension requirements, the 2025 Water Quality Report, the service line inventory submitted in October 2024, the SRP and APS address lookups, the Estimate Residential Water Rate Charges tool, and a complete SPDS with the sewer verification question answered. With 82 days on market citywide in September 2026 and 96.4% of asking price as the average sale-to-list ratio, you have both the time and the negotiating position to get all of it before you remove contingencies. Send me the address you are considering and I will walk the utility and water verification list with you before you write the offer.

FAQ

How do I confirm a Scottsdale property is actually connected to city water and sewer?

Start with the City of Scottsdale General Plan 2035 Water Resources Element map, which shows Northern, Central and Southern Water Service Regions along with wastewater service areas and treatment facilities, then confirm the parcel itself. Scottsdale City Code requires property owners to extend public water and sewer lines to their property as a condition of receiving service, so being inside a service region does not mean a line reaches the lot. The city's water and sewer planning page covers sewer taps, the Line Extension Participation Program, water and fire line extensions, and the related fees and permits.

Does my Scottsdale home have APS or SRP, and can I choose?

You cannot choose. Service follows the address under territorial agreements dating to 1954 and 1955. Scottsdale is split between two electric utilities, with APS serving the north and the old townsite and SRP serving most of the south, and the city's General Plan electrical map shows SRP serving south Scottsdale from about McDonald Drive and Chaparral Road to the Salt River. Confirm by address using SRP's lookup at srpnet.com or APS's service area maps, or by reading the utility name at the top of the first page of the current electric bill.

How is a Scottsdale sewer bill calculated?

Scottsdale states that sewer fees are based on most of a household's winter water use. Under the sewer rate schedule effective July 1, 2024, the monthly wastewater service charge is calculated by multiplying 90% of the customer's average winter consumption for the prior December, January and February by the applicable rate. Single-family residential wastewater rates total $2.97 per unit, which includes operations and maintenance plus capital, and all wastewater users pay a base fee of $7.75 for 5/8, 3/4 and 1 inch meters.

What does the Arizona SPDS have to disclose about utilities and sewer?

The Residential Seller's Property Disclosure Statement is a 10-page Arizona Association of Realtors form covering six major categories including utilities, and it is due within three days of contract acceptance. The utilities section requires the seller to list the provider for each utility, including electrical, fuel, cable, internet, phone, garbage, water and fire, and to disclose any known drinking water problems. The sewer section asks whether the entire property is connected to a sewer, whether a professional has verified the connection, the type of sewer, and the date of the last inspection, and it carries a notice to the buyer to contact a professional to conduct a sewer verification test.

Should I worry about lead service lines in Scottsdale?

Check the inventory for the specific address. The EPA Lead and Copper Rule Revisions require all community water systems to complete a material inventory of service lines, and Scottsdale's initial inventory was submitted in October 2024 and is available online, though some homes and businesses remain incomplete. The exterior service line connection is inspected by Scottsdale Water or a third-party contractor for the city, and if a lead service connection is found the owner is notified and the city works on replacing the line.
