How to Pay a Casper Water, Sewer or Sanitation Bill

Payment method
Official detail
Best for
Watch out for
Online portal
The City of Casper E-Billing & Payment Portal includes Utility Billing Account Management and a Sign In / Register route.
Customers who want to pay online, use QuickPay, register, view bills, track water use or manage account history.
Use the official Casper portal, not a search ad or similarly named third-party bill site.
QuickPay
The new portal requires the account and customer numbers from the utility bill for QuickPay and registration.
Fast payment when you have the current bill in hand.
Enter leading zeros and verify the address before submitting payment.
Registered account
The portal supports one-time payments, Auto Pay, e-billing, multiple accounts, bill viewing and transaction history.
Owners, renters, property managers and customers with more than one service address.
New registration was required when Casper moved to the new portal, so old login assumptions may fail.
EasyPay ACH
ACH direct withdrawal from a personal checking or savings account.
No checks, no due-date reminders, no mail, no line and no credit/debit card fees.
Print and complete the form, attach a voided check and return it to Utility Billing at City Hall.
Phone payment
Call 1-888-757-9544. Balance check is free; phone payment is listed with a $1.50 additional charge and card fees may apply.
Customers who prefer phone payment or need to confirm balance before paying.
Have account number ready and save confirmation.
Mail
Mail payment to City of Casper, 200 N. David, Casper, Wyoming 82601.
Routine check or money-order payments.
Mail is risky if the account is already 31 or 45 days past due.
City Hall drop box
Drop box at City Hall, 200 N. David, south parking-lot entrance.
After-hours check or money-order drop-off.
Processed weekdays at 8 a.m.; not ideal for same-day urgent restoration without calling.
In person
Finance Customer Service at City Hall, 200 N. David Street.
Receipts, billing questions, deposits, payment arrangements and turn-on concerns.
Thursday opens later at 9 a.m.; call first for urgent service issues.
Card or e-check online
Casper states card payments are processed by a merchant processor and fees are not City profit.
Convenient payment when fee is acceptable.
Public City guidance says card payments have a minimum $2 or 3.25% charge, whichever is greater; confirm the live fee before submitting.

Fee-free strategy: Casper’s official portal announcement says fee-free options include ACH/EasyPay, mailing the payment or bringing payment to the City. Use the live portal screen to confirm any card, e-check or phone-pay processing charge before final submission.

Payment confirmation script: “I paid City of Casper utility account [account number] for [service address] on [date/time] by [portal/QuickPay/EasyPay/phone/mail/drop box/in person]. Confirmation or check number is [number]. Can you confirm the payment posted and whether any 31-day late fee, 45-day fee, turn-on fee, deposit, sanitation charge, sewer averaging issue, reread fee or shutoff balance remains?”

Casper Utility Billing Login, QuickPay and Account Management

🔐

Portal features

  • Sign in or register.
  • Use QuickPay with account details.
  • Make one-time payments.
  • Enroll in Auto Pay.
  • Choose e-billing.
  • Manage multiple accounts.
  • View bills and transaction history.
  • Track water use where portal data is available.
🧾

Numbers you need

Use the account number and customer number from the current utility bill. The City notes that these numbers are needed for QuickPay and registration even if a customer previously used the older online portal.

⚠️

Do not guess

If the portal cannot find the account, shows the wrong address, or the account/customer numbers do not match the bill, stop and call 307-235-8400 option 2 before paying.

Open the official payment portal

Start from the City of Casper utility payment page or open the Municipal Online Payments portal. Confirm the page says City of Casper E-Billing & Payment Portal.

Choose Utility Billing Account Management

The portal also lists municipal court, so choose the utility billing option when paying a water, sewer or sanitation bill.

Use QuickPay or register

QuickPay works for a one-time payment. Registration is better if you want e-billing, Auto Pay, multiple accounts, bill images, transaction history and ongoing usage tracking.

Save proof before closing the page

Download or screenshot confirmation number, amount, date/time, payment method, account number and service address. This is important for late accounts or turn-on requests.

Landfill pass note: Casper’s portal launch announcement said customers who use the monthly utility bill as a one-time free pass to the landfill can bring the bill up on their phone at the solid waste facility. Registering for online access can make that easier to show.

Late Fees, Deposits, Turn-On Fees and Reread Charges

31st day

Updated utility-fee notice lists a $20 delinquent late fee on the 31st day.

45th day

An additional $35 fee applies at the 45th day, making the listed late-fee total $55.

Turn-on

Water turn-on fee is listed at $35, with shutoff-related situations potentially totaling more.

Deposit

Refundable utility deposit is listed as $100 with ACH autopay and $200 without ACH autopay.

Fee / issue
Current City notice says
Customer action
31st-day late fee
$20 delinquent late fee.
Pay or call before the account reaches deeper delinquency.
45th-day fee
$35 additional fee on top of the $20 31st-day fee, for a total of $55.
Ask Utility Billing for the exact full amount due before paying an older statement.
Water turn-on fee
$35 listed water turn-on fee.
Call billing after payment if you need restoration, because payment alone may not answer field scheduling questions.
30-day-late shutoff situation
City fee notice says if you are 30 days late, a shutoff fee will be added, totaling $90.
Ask whether your account is still only past due or already in shutoff/turn-on status.
Refundable utility deposit
$100 for accounts with ACH autopay; $200 for accounts without ACH autopay.
Ask if enrolling in ACH/EasyPay changes deposit treatment for your account.
Deposit waiver possibility
New customer deposit may be waived with a letter from a previous utility company showing 12 months of good history.
Request that letter before start-service date if possible.
Existing delinquent customer deposit
City reserves the right to require deposits for existing delinquent customers.
Ask whether deposit is part of the amount required to restore service.
Unsubstantiated reread
$102 fee listed for unsubstantiated reread of a water meter.
Check toilets, irrigation and visible meter data first so you do not pay for a reread caused by a customer-side issue.
Insufficient check
$30 insufficient-check fee.
Ask whether returned payment changes accepted payment methods.
Frozen meter
$66 plus meter cost, with a 3/4-inch meter example listed at $246.
Winterize meter areas, basements and crawl spaces before extended cold periods.
Late-bill script: “My City of Casper utility account [account number] is late or has a shutoff/turn-on issue. Can you confirm the exact balance, whether the 31st-day $20 fee, 45th-day $35 fee, shutoff/turn-on fee, deposit, insufficient-check fee or reread charge has been added, and which payment method posts quickly enough today?”

Casper Residential Water, Sewer and Sanitation Rate Basics

Rate schedule

The City’s residential rate page says a new schedule was approved effective January 1, 2025.

Water minimum

The public rate summary lists $13.45 for the first 1,500 gallons consumed as the minimum monthly water fee.

Sewer averaging

Residential sewer averaging is recalculated annually using January, February and March water usage.

Sanitation

Residential weekly pickup minimum monthly fee is publicly listed at $31.70.

Bill line
What it means
Customer check
Water minimum / base usage
Current public summary lists $13.45 for the first 1,500 gallons consumed as the minimum monthly water fee.
Even low-use or vacant homes may still have minimum charges.
Water usage above minimum
Additional consumption can increase the water portion of the bill.
Compare gallons to the same month last year and to recent irrigation use.
Sewer charge
Residential sewer averaging is based on January, February and March usage because those months better reflect indoor wastewater flow rather than summer lawn watering.
Fix leaks before winter averaging months because those months can affect future sewer billing.
Commercial sewer
Commercial sewer billing may differ from residential winter averaging and can be tied to actual usage depending on class and policy.
Business customers should call before relying on residential examples.
Sanitation
City bills sanitation service on the utility bill; public summary lists residential weekly pickup minimum monthly fee at $31.70.
For trash pickup and landfill questions, call Solid Waste at 307-235-8246.
Card-processing fee
Casper public guidance states card payments carry a minimum $2 or 3.25% fee, whichever is greater, and the City does not profit from it.
Use EasyPay ACH, mail or in-person options if you want to avoid card fees.
Phone-pay charge
Phone-pay page lists $1.50 additional charge plus card fees.
Ask if the payment method posts immediately if you are late.
Re-read fee
Unsubstantiated reread fee is listed at $102.
Check for leaks and irrigation use first; request reread only when the reading seems truly wrong.
Updated rates
The City may update rates by Council action, budget cycle or published fee schedule.
Confirm the current live rate page before publishing a calculator or quoting a non-residential bill.

Sewer averaging tip: Casper’s annual residential sewer recalculation makes January, February and March important. A silent toilet leak, running humidifier, water softener issue or winter pipe leak during those months can raise the average used for future sewer charges.

High Casper Utility Bill: Water Leak, Sewer Average or Sanitation Charge?

Portal history

Use the new portal to view bills, payments, transaction history and usage information where available.

Toilet leaks

Silent toilet leaks can raise both water usage and winter sewer averaging.

Irrigation

Summer lawn watering can increase the water bill even when sewer averaging limits sewer impact.

Sanitation

Trash, landfill and sanitation questions may need Solid Waste, not only Utility Billing.

Bill clue
Likely cause
Customer check
What to ask Casper Utilities
Water usage jumped
Toilet leak, irrigation, outdoor hose, water softener, humidifier, underground line leak or actual seasonal use.
Turn off all water and watch meter movement if accessible; check every toilet, irrigation valve and hose bib.
“Can you review usage history and tell me if the increase appears continuous or seasonal?”
Bill seems high in January-March
Winter usage may affect annual sewer averaging.
Fix toilet/plumbing leaks quickly during the first quarter.
“Will this January, February or March usage be included in my sewer average?”
Water high but sewer stable
Outdoor irrigation or summer use may be affecting water more than sewer.
Check sprinkler run times, broken heads, drip zones and hose-end timers.
“Is my sewer charge based on the winter average rather than this month’s water use?”
Sewer charge rose after spring
Annual sewer average recalculated from January-March consumption.
Compare the winter bills that created the average.
“Which months were used for this year’s sewer recalculation?”
Sanitation charge seems wrong
Cart, weekly pickup, landfill, collection or solid-waste service issue.
Separate water/sewer from sanitation before disputing the bill.
“Should I call Solid Waste at 307-235-8246 for this charge?”
Meter reread requested
Customer suspects reading error, but City fee may apply if reread is unsubstantiated.
Check for leaks and take photos before requesting reread.
“Could a $102 unsubstantiated reread fee apply to my request?”
Account has old late fees
31st-day and 45th-day late-fee schedule, plus possible turn-on/deposit issues.
Ask for itemized balance, not just the current bill amount.
“Please separate usage, sanitation, late fees, turn-on fees, deposit and NSF charges.”
High-bill script: “My City of Casper utility bill increased from [old usage/amount] to [new usage/amount]. I checked toilets, irrigation, outdoor hoses, water softener, humidifier, visible leaks, sanitation charges, sewer averaging months and portal history. Can you review whether my usage pattern suggests a leak, whether a reread fee could apply, and which charges are water, sewer, sanitation, late fee or deposit?”

Where do I mail a City of Casper utility bill payment?

Mail payment to City of Casper, 200 N. David, Casper, Wyoming 82601. Include the account number and payment stub. Use a faster method if the account is close to late fee, shutoff or turn-on timing.

Does Casper charge card-processing fees for utility payments?

Yes. Casper public guidance says card payments have a minimum $2 or 3.25% charge, whichever amount is greater, and that the City does not profit from card-processing fees. The phone-payment page also lists a $1.50 additional charge for phone payment, plus card fees.

What is EasyPay for Casper utilities?

EasyPay is ACH direct withdrawal from a checking or savings account. The City says it avoids checks, due-date reminders, mailing, waiting in line and credit/debit card fees. To enroll, print and complete the authorization form, attach a voided check and return it to Utility Billing at City Hall.

What late fees can apply to a Casper utility bill?

The City’s updated utility fee notice lists a $20 delinquent late fee on the 31st day and an additional $35 on the 45th day, making the listed total $55. Ask Utility Billing for the exact account balance because turn-on, deposit, NSF, reread or other fees may also apply.

What deposit is required for Casper utility service?

The City’s utility fee notice lists a refundable utility deposit of $100 for accounts with ACH autopay and $200 for accounts without ACH autopay. A new customer deposit may be waived with a letter from a previous utility company showing 12 months of good history, and the City reserves the right to require deposits for existing delinquent customers.

Why is my Casper water or sewer bill high?

Common causes include toilet leaks, irrigation, outdoor hose use, water softeners, humidifiers, winter leaks, sewer averaging, sanitation charges and old late fees. Casper recalculates residential sewer averaging each year using January, February and March usage, so winter leaks can affect future sewer charges.
