Grand Prairie New Water Utility Customer Portal: What It Helps You Do
The City says the new Water Utility Customer Portal is designed as an all-in-one place to view billing statements, account details, water usage and payment options. This is useful not only for paying the bill but also for spotting unusual usage before a bill becomes stressful.
View statements
Use the portal to view current and past billing statements instead of searching old paper bills.
Review usage
Checking water usage can help you notice a leak, irrigation issue or unusual household use.
Go paperless
Registered customers can choose paperless billing and manage account information more easily.
1
Create an online account if you manage bills regularly
Registration gives more tools than one-time payment.
▾
Registering is helpful if you want to view statements, see account details, review water usage, manage payment settings or reduce paper bills.
2
Use one-time payment when you only need to pay quickly
Good for simple payment when you have your account number.
▾
The City says one-time payment can be made without registering. You need the account number from your paper bill.
3
Use usage history when your bill looks high
Usage history gives clues before calling.
▾
Before calling about a high bill, compare current use to past use. If the usage jumped, check toilets, outdoor faucets, irrigation, water heater relief valves, washer lines, dishwasher connections and other common leak points.

Grand Prairie Water Bill Tips That Save Time and Reduce Payment Problems

The portal is more useful when registered because you can see statements, account details and water usage.
