The Arlington Water Utilities mobile app is now available for download on the Apple App Store and Google Play, offering convenient access to the City of Arlington’s Know Your H2O customer portal.

With the Arlington Water app, residents with water and sewer accounts can:

• View and pay their Arlington Water Utilities bills.
• Track water usage by the hour, day, or month.
• Set up alerts to notify them when water usage is higher than expected.

To find the app, search for “Arlington Water” in the online store that is compatible with your mobile device. Then, use the credentials from your online account to log in or register for a new KnowYourH2O account.
