This guide explains how to enroll in Wilmington water bill AutoPay through the Enquesta portal, what to do if your old AutoPay was already active, how to register with a new account number, how to use online pay safely, and what to do if your account is past due or at risk of shutoff.
Wilmington Water Bill Payment Finder: Which Option Should You Use?
Wilmington has more than one way to manage a water/sewer/stormwater bill. Choose the right option based on whether you want AutoPay, a one-time payment, old portal help, account-number help, assistance, or emergency contact.
How to Enroll in Wilmington Water Bill AutoPay in 2026
AutoPay is best for customers who want the bill paid automatically instead of logging in each billing cycle. The new Enquesta portal is the main place to manage online account details, view bills, set up AutoPay and track usage.
Open the official Enquesta portal
Start from the City’s official Enquesta portal. Do not use a third-party bill payment site when setting up automatic payments.
Register or sign in with the correct account information
Keep your most recent Wilmington water bill nearby. The portal may require the new account number, and the City says customers can call 311 or 302-576-2620 if they need help registering before receiving the new account number.
Go to payment settings
After login, choose the option to manage payment methods or automatic payment. Review the account, service address and bill balance before saving any AutoPay method.
Add payment method carefully
Enter bank or card details exactly. If using a bank account, check routing and account number twice. A failed automatic payment can create late-payment problems.
Confirm AutoPay activation
After enrollment, check for confirmation. Keep one manual reminder for the next bill until you see the first automatic payment post correctly.
Already Had Wilmington AutoPay? What Changed With the New Portal
Wilmington’s portal guidance says customers who previously signed up for AutoPay through the former Paymentus portal before the June 28 transition should use the “Forgot your password?” option to access the new portal. The City also says existing AutoPay information was stored in the new portal and will continue to process even if you do not sign in.
Old AutoPay customer
Use the “Forgot your password?” option in the new portal to complete your first login.
New account number
The City says the new account number is provided with the July bill, and customer service can help if you need it earlier.
AutoPay continues
The City says previously enrolled AutoPay can continue processing even if you do not sign in right away.
Open the new Enquesta portal
Use the official new portal, then choose “Forgot your password?” rather than creating a duplicate profile.
Use the account details requested by the portal
Follow the prompts. If the portal asks for the new account number and you do not have it, call 311 or 302-576-2620.
Verify AutoPay after first login
Once inside the portal, check whether payment method, AutoPay status, account number and service address are correct.
How to Pay a Wilmington Water/Sewer/Stormwater Bill Online
The official Enquesta portal lets customers view and pay bills online, review transaction and payment history, analyze and download water usage, and add multiple accounts to a web profile.
Open the official portal
Use the City’s Enquesta portal or the official pay/manage account page. Avoid unofficial bill-payment websites that are not the City’s portal.
Have your most recent bill ready
The portal sign-up page says to have your most recent bill handy. This helps you enter account details exactly as shown.
Confirm water, sewer and stormwater charges
Wilmington bills may include water, sewer and stormwater. Review the full bill before paying so you understand the total.
Save payment confirmation
Keep the confirmation number, amount, date, payment method and account number until the transaction appears in payment history.
Enquesta Portal Login and Registration Troubleshooting
Most online payment issues happen because customers use an old login, old account number, wrong customer details, or an outdated saved payment link. Use this checklist before calling.
| Problem | Likely reason | Best next step |
|---|---|---|
| Old portal login does not work | The City moved to the new Enquesta portal. | Use “Forgot your password?” if you had old AutoPay, or call 311 for help. |
| Portal asks for new account number | New billing system uses updated account details. | Check your July or newer bill, or call 302-576-2620 outside city limits. |
| Account not found | Name, address or account number may not match the bill exactly. | Use your most recent bill and enter information exactly as printed. |
| AutoPay status unclear | Old AutoPay migrated, but you have not verified it in the new portal. | Sign in and confirm payment method, scheduled payment and account details. |
What to say when calling customer service
Say: “I am trying to register in the new Enquesta water billing portal. I need help confirming my new account number and AutoPay status.”
Pay by Phone, Mail or Drop Box
Wilmington customers can pay online, call 311 and ask for an agent, use the telephone payment system, pay by mail, or use the City drop box. Mail or drop box may be useful for routine payments, but they may be risky for urgent or shutoff-related accounts.
Call customer service
Call Wilmington 311 for help. If calling from outside City limits, use 302-576-2620.
Drop box
The City lists a drop box in the lobby of the Louis L. Redding City/County Building at 800 N French Street.
Mail payment
If paying by check, write your utility billing account number on the check and include the bottom portion of the bill.
Past-Due Wilmington Water Bill, Shutoff Risk or Assistance Need
Wilmington has water/sewer bill assistance resources for residents behind on water bills. The City also has a Utility Payment Assistance Program, with eligibility and payment-plan requirements for remaining balances after grant funding.
Call 311 before making a partial payment
Ask whether the account is already in delinquent or shutoff status, what amount is required, and whether assistance or a monthly payment plan is available.
Ask whether you qualify for utility assistance
Wilmington’s Utility Payment Assistance Program includes income rules and may require proof of income, property information, and agreement to pay remaining balances or enter a monthly payment plan.
Confirm account balance with customer service
If your account is delinquent, online search results may not reflect all additional charges. Ask customer service for the real amount needed.
Save all payment and case proof
Keep confirmation numbers, assistance application proof, customer service notes, caseworker emails and payment receipts.
Use the Portal to Track Water Usage and Avoid Surprise Bills
The Enquesta portal is useful beyond payment. It can help you review payment history and analyze water usage. This is important because a high bill may come from increased usage, a running toilet, irrigation, a leak, previous balance or stormwater/sewer charges.
Track usage
Compare current usage with previous periods. A sudden jump can indicate a leak or unusual household use.
Review transactions
Check whether recent online, phone or mailed payments appear correctly in payment history.
Manage multiple accounts
The portal supports adding multiple accounts to a web profile, which is useful for landlords or owners managing more than one property.
Start or Stop Wilmington Water/Sewer Service
If you are moving in, selling, renting, buying, managing a property or closing an account, use the official Wilmington Water Utility service resources before relying only on payment portal access.
Start/stop service path
The Wilmington Water Utility site links to Start/Stop Water/Sewer Service from its pay/manage account resources.
Call before move date
Call 311 or 302-576-2620 before your move date to confirm account setup, service status, final bill, or transfer requirements.
Move-in and move-out checklist
Keep your service address, closing or lease date, owner/tenant information, account number if available, forwarding address, phone number, email and final payment confirmation.
