Los Alamos County is pleased to offer you the Los Alamos DPU App, a convenient way to manage your utility account more effectively online or on your mobile device at no cost to you!  Enjoy the following benefits with this new and innovative tool: view and pay your bills, monitor consumption to gain insight into your usage patterns, move your service and more!


I’ve used the online system in the past, but my login information doesn’t work anymore.

Los Alamos DPU Portal is our new customer interface and requires registration. If you have not registered on this new site, you must do so to access your account online.

I have multiple accounts, but can’t add them all to my online registration / account.

Each utility account number must have a separate email address. Your e-mail address is tied to the registration and creates a unique ID in our software database. We are aware of how this impacts our customers with multiple accounts and apologize for any inconvenience this may cause.  Due to the agreement with our software vendor, we are unable to alter this requirement.

I registered my account, but I still can’t log in or pay my bill.

After registration, a confirmation email link will be sent to the email address you provided during your registration. You must activate your account from this link in order to access your account and payment options.

Am I required to input home data when prompted (e.g., square footage, number of rooms, etc?

No, this is optional. You can complete this information at any time, if you choose.

I have a business account. What do I enter in the LAST NAME field?

Businesses must use the entire name in the “last name” field, including any punctuations. If you are unsure, please feel free to contact our Customer Care Center at 662-8333.

I want to make a payment online. Is that available?

The Los Alamos DPU App online payment options available are credit card (Visa, MasterCard, and Discover), debit card, and E-check. Please remember when making an E-check payment, that you must enter the entire account number, including any preceding and ending zeroes. If you have questions regarding your checking account number, please contact your financial institution.

I selected "Pay Bill" like I used to on the County’s old site, but an error pops up that says it doesn’t recognize my information.

As of March 15, 2017, all customers must register their account in the new Los Alamos DPU App.

Where do I find my account billing and payment history?

The Los Alamos DPU App still provides 13 months of account billing and payment history, similar to our previous online system. To find your billing and payment account history, select the “Billing" icon (the $ image) then “History” tab.  Located in this tab are PDF versions of your last 13 bills, simply click the “View” option.

Why does the dollar amount on the dashboard still say I owe a payment when I paid it already?

The dashboard reflects the total amount due from your last bill, not the current amount due. Please click on the “Billing” icon (the $ image) and “History” tab to see all payments made since the last bill was issued.

What if I want to change my payment type?

Our Los Alamos DPU App allows our customers to save one payment type.  If you wish to change this, you can do so anytime by going to the “My Account” module and “Payment Info”. You will always be asked to provide your password again when requesting to view payment information.  There is an option to delete or edit your saved payment information.  When you delete your saved payment information an option will appear to “Add Payment Method” towards the bottom left hand of the screen.
