CUSTOMER SERVICE & BILLING

Our customers are our number one priority. Here you'll find useful information about your service, your bill, and your rights and responsibilities as a Hawaii American Water customer. 

We’ve always offered 24-hour customer service, but now that service is even more convenient when you manage your account online. By managing your account online, you can:

• set up accounts
• pay bills at your convenience
• request a time to have your service initiated or canceled

We welcome your feedback and want you to share your stories about your experience with us.
