I personally use the electronic check option cause it doesn’t have any processing fees, but you do you!

2. Look for “AutoPay” or “Recurring Payments”
3. Choose your preferred payment method

• Update your payment methods if you get a new card
• Check your email for bill notifications
• Review your usage occasionally to catch potential leaks

Is ONWASA Online Bill Pay Secure?

This is a big question for a lot of people, and I get it. The good news is that ONWASA uses industry-standard encryption and security measures for their online portal. Your financial information isn’t stored on their servers, which adds another layer of protection.

The system meets all the regulatory requirements for handling payment data, so you can feel confident that your information is protected.

Mobile-Friendly Experience

One thing I really appreciate is that the ONWASA payment portal works great on smartphones too. Sometimes I’m paying bills while waiting in line at the grocery store (multitasking for the win!). The mobile version is easy to navigate and all the same features are available.

Other Ways to Pay Your ONWASA Bill

While online payment is super convenient, ONWASA does offer other payment options:

• By phone (automated system)
• Mail in a check
• In person at their office
• Payment drop box (if you’re dropping off after hours)
• Through your bank’s bill pay service

But honestly, once you try the online option, you probably won’t go back to these other methods.

Managing Multiple Properties

If you’re a landlord or own multiple properties serviced by ONWASA, you’re in luck. The online portal allows you to manage multiple accounts under one login. This saves so much time!

Just register each account to your profile, and you’ll be able to switch between them easily to view bills and make payments for each property.

• Fix leaky faucets and toilets ASAP
• Install low-flow showerheads
• Run full loads in your dishwasher and washing machine
• Water your lawn during cooler hours
• Consider water-efficient appliances when upgrading

The usage tracking in your online account can help you see if these changes are making a difference!
