Customer Portal, Smart Meters and Leak Alerts
Oro Valley announced in 2026 that online billing and water monitoring were consolidated into the existing customer portal. WaterSmart service is being discontinued after June 30, 2026, so the portal and Smart Meters tool matter more now.
Portal does more than bill pay

- View usage history.
- View billing summaries.
- Pay your bill.
- Submit common requests.
Smart Meters tool
- See usage trends.
- Forecast costs.
- Set leak alert thresholds.
- Set service notifications.
- Use email, text, in-app, chat, or phone notifications.
Sign-up checklist
- Grab latest water bill.
- Open Customer Portal Sign Up.
- Enter account information.
- Activate Smart Meters from the left menu.
- Call 520-229-5000 if setup fails.
Portal timing: the customer portal is monitored during regular business hours. Requests submitted after hours are answered the next business day. For true water emergencies after hours, call 520-229-5000 and select option 1.

High Bill or Leak Alert: Desert-Smart Troubleshooting
Meter check
Most meters are underground in boxes near the curb. The “+” symbol on digital meters appears when water is flowing. If water is off and the meter still shows flow, suspect a leak.
Oro Valley outdoor suspects
- Drip irrigation under gravel.
- Valve box leak.
- Pool autofill.
- Hose bib or nozzle leak.
- New plants or landscape work.
Smart alert proof
- Portal usage graph.
- Leak alert date/time.
- Repair receipt.
- Before/after meter reading.
- Photos of leak or repair.
| Check | Official/useful detail | What to do next |
|---|---|---|
| Residential average use | 5/8 inch and 3/4 inch meters average about 5,000-7,000 gallons/month; 1 inch meters average about 16,000 gallons/month. | Compare your usage with the bill period, household size, pools, irrigation, and landscaping. |
| Digital meter low-flow indicator | Numbers changing to the right of the decimal can show low flow; “+” symbol indicates water flowing. | Turn off all water and check whether flow continues. |
| WaterSmart / portal data delay | Hourly data can have a 6-8 hour delay or more because of the amount of transferred meter data. | Do not assume the portal is real-time to the minute. |
| Leak alert threshold | WaterSmart FAQ listed continuous alerts at 10 gallons/hour for at least 72 hours, or 75 gallons/hour for at least 8 hours. | Use the new portal Smart Meters tool to set current thresholds and notifications. |
| Free water audit | Oro Valley Water Utility says customers can call 520-229-5000 to schedule a one-time free water audit. | Use for home, business, or HOA water-use review. |

Water Quality: What Oro Valley Customers Ask Most
System ID
Oro Valley Water Utility
PWS ID: AZ04-10-164
CCR contact: Adam Pence, Water Operations Supervisor
520-229-5042
apence@orovalleyaz.gov
Water source
2025 CCR lists groundwater from the Upper Santa Cruz Sub-Basin of the Tucson Active Management Area, plus 35% CAP water blended with groundwater through Tucson Water system connections.
Call for unusual water
For cloudy/silty water, unusual odor, taste, or serious water-quality concern, call 520-229-5000 so the Utility can investigate.
| Question | Official useful answer | Action |
|---|---|---|
| Is fluoride added? | No. Oro Valley Water Utility says it does not add fluoride to the drinking water system; naturally occurring fluoride may be present from aquifer minerals. | Check the CCR fluoride value if you need current detected level. |
| Why does water smell/taste like chlorine? | Chlorine is added in small amounts for disinfection; summer heat can make chlorine smell/taste more distinct. | Call if the odor is unusual, sudden, or persistent. |
| Why is cold water warm in summer? | Water pipes absorb heat from surrounding ground in summer. | Usually normal in hot months; call if paired with odor/color issue. |
| Why is water white? | Tiny air bubbles often clear after a few minutes and are not harmful to health or plumbing. | Let a clear glass sit and see if it clears. |
| Why is water blue? | Copper plumbing can cause bluish water, especially in new pipe. | Call if it persists or you have plumbing/health concerns. |
| What is water hardness? | Oro Valley hardness ranges from 36 ppm to 270 ppm; classifications: soft 0-60, moderately hard 61-120, hard 121-180, very hard over 180 ppm. | Divide ppm by 17.1 to estimate grains per gallon. |
| Does my home need treatment? | The Utility says treatment systems are a personal preference; if installed, maintain them per manufacturer instructions. | Poorly maintained systems can create water-quality issues. |
| Does Oro Valley test throughout the system? | The Utility samples at about 15 Entry-Point-to-the-Distribution-System sites and 58 neighborhood sampling stations, with lead/copper from 50 private residences. | Use the CCR for official compliance data. |

Annual testing
Customers with service-protection backflow assemblies are notified by mail when yearly inspection is due.
Certified contractor required
Testing, repair, installation, retrofit, and replacement work must be done by a certified contractor. Installation/retrofit/replacement requires a plumbing permit.

Stormwater and Sewer: Why They Show Up in Water Searches
Stormwater fee
Oro Valley’s stormwater utility fee is a flat $4.50/month for residences. Oro Valley Water Utility customers see this fee included and itemized on their monthly water bill.
Tucson Water, Metro Water, and well-water customers receive a separate quarterly bill of $13.50 in January, April, July, and October.
Sewer routing
For sewer-related issues, Pima County lists 520-724-3400 24/7. Sewer billing questions go to 520-724-6609 during business hours.
Bill confusion fix: water, stormwater, and sewer are not always handled by the same department. Use the right route before disputing a charge.
