Find Your Acadiana Water Provider, Pay a Bill or Contact Customer Service

Trying to pay an Acadiana water or sewer bill? Your payment website and customer service number depend on the company named on your statement.

Magnolia Bill Pay / Login Call Magnolia Water

Check the provider before paying. Acadiana is a region of Louisiana, not a single water utility. The Louisiana Public Service Commission also lists Acadiana Water & Sewer, Inc., with a Duson address and phone number. Do not assume that every account with “Acadiana” in its name belongs to Magnolia Water.

Which Water Utility Company Serves Your Acadiana Address?

Acadiana includes communities across Lafayette, Acadia, Iberia, St. Landry, St. Martin, Vermilion and neighboring parishes. Water and wastewater service may come from different companies even within the same parish.

Name on Your Bill	Correct Starting Point
Magnolia Water Utility Operating Company	Magnolia Water official customer website
Acadiana Water & Sewer, Inc.	Confirm the current account administrator through the Louisiana PSC utility record or the number on your bill.
Louisiana Water Company (LAWCO)	LAWCO payment options
Lafayette Utilities System (LUS)	Official Lafayette Utilities System website
Another municipal or subdivision utility	Use the exact company name, service address and account details printed on the bill.

Three Ways to Confirm Your Provider

Read the billing statement. Find the utility’s legal name and account number. The name of the community or subdivision alone may not identify the billing company.
Check the payment instructions. Magnolia customers are directed to CSWR AuthorityPay. LAWCO customers follow Louisiana Water Company’s separate payment system.
Verify an unfamiliar bill. Check the company’s official website or Louisiana PSC utility listing before entering payment details.

Local example: A customer in Crowley may receive service from Louisiana Water Company, while a household in another Acadia Parish subdivision may have a different provider. Living near Lafayette does not automatically mean you are served by LUS.

Forgotten Login or Missing CID

If you cannot register, first check the latest water or wastewater bill for the customer account number and CID. If the bill is unavailable or the account details do not match, call Magnolia customer service rather than guessing credentials or opening multiple accounts.

Magnolia Water Fees, Due Dates and Late Payments

Magnolia publishes the following general billing and processing charges. Connection, deposit and reconnection amounts may depend on the tariff that applies to your particular water or wastewater system.

Charge	Published Information
Credit/debit processing fee	2.25% of the payment balance
Electronic check fee	$0.75 flat fee
Late payment fee	5% of unpaid balance
Returned check	Amount depends on approved tariff
Disconnect/reconnect	Depends on the utility’s approved tariff
Monthly due date	Last business day of the month

Magnolia states that bills for the preceding month are generally mailed during the first week of the next month. The account becomes delinquent when the required payment has not been received by its due date.

What Happens After a Missed Payment?

The unpaid balance becomes overdue after the published due date.
A late charge can be applied to the outstanding amount.
Magnolia states that customers receive at least 10 days’ mailed notice before service discontinuance.
To prevent or resolve disconnection, contact customer service about the full amount due and payment options.
If service has been shut off, any applicable shutoff or reconnection charges must be addressed before restoration.

Need more time to pay? Magnolia offers eligible customers payment arrangements. The company describes a plan that includes the current month’s bill plus a portion of the past-due balance. Call 1-855-643-8152 before the deadline and ask whether your account qualifies.

Start, Stop or Transfer Water and Sewer Service in Acadiana

If Magnolia Water serves your property, begin service changes directly through its official customer website. Do not use an existing-customer contact update form to open a new account.

Starting Service at a New Address

Visit Magnolia Water.
Choose Start or Stop Service.
Select the option to start service.
Provide the service address, applicant details and other information requested.
Review the required deposit, activation charges and start date with the utility.
Keep a copy of your application or confirmation.

Closing Your Account When Moving

Use the same Start or Stop Service section to request disconnection. Confirm the final service date, forwarding address and final balance. If you pay automatically, confirm how the last bill will be handled before removing your payment method.

Subdivision tip: A property can have one company for drinking water and another for wastewater. When buying or renting a home in Lafayette, Duson, Youngsville or nearby communities, ask specifically for the names of both providers before setting up utility accounts.

Common Acadiana Water Utility Problems and What to Do

Water or Sewer Service Suddenly Stops

First determine whether the problem involves only your property or neighboring homes. If you are a Magnolia customer, call 1-855-643-8152. Magnolia states that after-hours personnel can receive emergency information and arrange assistance.

Prepare your address, subdivision or system name, description of the issue, when it began and whether nearby homes are affected.

Water Bill Is Much Higher Than Normal

Check whether the increase is in water consumption, wastewater service, fixed charges or a past-due balance. Review the meter readings and billing period. Inspect toilets, faucets, irrigation lines and wet areas around the property.

Do not assume that a higher wastewater charge means more water was used. Some wastewater accounts are billed at a flat tariff rate rather than metered household consumption.

Payment Completed but Still Shows Unpaid

Keep the receipt, check your payment account and allow for processing. Call customer service with the exact payment date, amount and confirmation number. If the payment was made through an outside service, ask whether Magnolia has received notification.

Boil Water Advisory or Unusual Water Quality

Check Magnolia’s Service Alerts section for notices affecting your water system. Search by location or system when available.

If a boil water notice is active, follow the utility’s instructions for drinking, cooking, preparing food and other household uses. Continue following the notice until the responsible utility announces it has been lifted.

Unable to Find Your Water Quality Report

Open Magnolia’s Regulatory Information section and look for your specific water system, subdivision or public water system identification number. Different systems in Acadiana may have separate Consumer Confidence Reports and service notices.

How to File an Unresolved Utility Complaint in Louisiana

Magnolia Water Utility Operating Company is regulated by the Louisiana Public Service Commission. If customer service does not resolve a billing, service or tariff issue, customers may request regulatory review.

First contact Magnolia at 1-855-643-8152 or support@magnoliawateruoc.com.
Document dates, previous responses, charges, payment confirmations and any service notices.
Visit the Louisiana Public Service Commission.
Find the consumer complaint or commissioner contact information.
Explain the issue clearly, identify the utility and provide supporting documentation through the official process.

The Louisiana PSC separately lists Acadiana Water & Sewer, Inc. in Lafayette Parish and Magnolia Water Utility Operating Company across multiple Louisiana parishes. Use the exact regulated utility name when requesting help.

Do not confuse related company names. Magnolia Water Utility Operating Company, Magnolia Plantation Water Systems in Abbeville and Louisiana Water Company are distinct entities with different customer billing systems. Never use a payment link simply because it contains the word “Magnolia” or “Louisiana.”
