Official payment route

How to Pay a Carbondale Water / Sewer Bill

Official City payment page

Carbondale Online Bill Pay

The City provides separate online options for normal water/sewer payments, reconnect fees and paying another person’s water bill.

Open Bill Pay
  1. 1

    Use your current bill

    Have the account information and service address in front of you before starting the payment.

  2. 2

    Open the City payment page

    Use explorecarbondale.com rather than an unfamiliar third-party payment page.

  3. 3

    Choose Water / Sewer Bill

    The City also provides separate routes for reconnect fees and payments made on behalf of another customer.

  4. 4

    Verify the account

    Confirm that the service address and account information match the property you intend to pay.

  5. 5

    Save the payment confirmation

    Keep the receipt or confirmation number until the payment is reflected on the account.

Past the due date? Do not rely on normal online payment.

The City’s online-payment page specifically warns customers trying to avoid an interruption of service not to pay online after the due date. Call the Revenue Office at (618) 457-3265 for instructions.

Other payment methods:

The City’s water-service agreement states that payments may be made at City Hall and identifies cash, check, qualifying credit/debit cards and automatic bank payment among available methods. Current processing rules or fees should be confirmed before payment.

05

Moving to Carbondale

How to Start Water, Sewer & Refuse Service

Carbondale provides separate online service-connection forms for residential and commercial customers. The City’s current new-resident guidance recommends submitting the request at least three days before the connection is needed.

Residential deposit $100 Current City new-resident guidance
ID requirement Photo ID Driver’s license or state-issued ID
Advance request 3+ days Recommended to avoid delay
Customer office (618) 457-3265 Revenue Office
  1. 1

    Choose residential or commercial

    Use the appropriate City connection form for the type of property being served.

  2. 2

    Enter the requested connection date

    Submit early enough for the City to process the request and schedule any necessary utility work.

  3. 3

    Upload valid identification

    The City’s residential instructions require a valid driver’s license or state-issued photo ID.

  4. 4

    Pay the applicable deposit

    The current residential connection guidance lists a $100 residential deposit. Commercial requirements can differ.

  5. 5

    Confirm the account is approved

    Do not assume submission of the form alone means water will be turned on at a particular time.

Official new-resident instructions

Includes service connection steps, deposit information and customer requirements.

New Resident Info
Some Carbondale addresses use another water district.

The City notes that although municipal sewer service is provided to residents, some properties can receive water from a separate water district. In that situation, the customer may need to establish service with both utilities.

06

Moving out

How to Stop Carbondale Water Service

The City advises customers to contact the Water/Revenue Office when they move. Customers can continue to be billed through the date service is actually disconnected.

  • Call (618) 457-3265. Tell the Revenue Office you need to terminate service.
  • Provide the service address. Use the exact address shown on the utility account.
  • Give the requested disconnect date. Do not assume a lease end date automatically closes the City account.
  • Provide a forwarding address. Ask where any final bill or account correspondence will be sent.
  • Confirm completion. Verify the account has actually been closed after the requested service date.
Moving does not automatically cancel utility billing.

The City’s service forms specifically warn customers to request disconnection when moving because billing continues through the date the service is disconnected.

07

24-hour response

Water Outage, Main Break or Sewer Backup

24 hours a day

Carbondale Water & Sewer Hotline

Use the hotline for water outages, sewer backups, water-main breaks and other urgent utility problems.

Call (618) 529-1731

No Water

Check whether the entire property is affected and whether neighboring properties also have no service.

Water Main Break

Report the street, nearest address or intersection and describe where water is surfacing.

Sewer Backup

Avoid contact with wastewater and report an active municipal sewer emergency to the hotline.

Immediate danger?

Call 911 when flooding, damaged infrastructure or another utility incident creates an immediate threat to life or safety. Do not enter a washout, flooded electrical area or unstable roadway.

08

High usage & bill adjustment

Carbondale Water Bill Suddenly Too High?

Carbondale’s water/sewer code includes an unusually specific process for customers who believe a bill is too high. A customer can request an investigation orally or in writing.

City investigation

Potential high-bill adjustment

Under the currently published ordinance, when the investigation finds no negligence or fault by the customer and that account has not received an adjustment during the previous 12 months, an adjustment may be made.

The ordinance describes the adjustment as 50% of the charges on the high bill, but the adjusted amount cannot be below the customer’s average bill or applicable minimum bill.

Average bill

How the ordinance calculates history

The published rule uses average consumption over a six-month period from the previous 12 months of billing history.

If sufficient history is unavailable, the Finance Department may establish an average consumption for the account.

What to do before calling

  1. 1

    Compare several bills

    Look at current consumption against your normal usage rather than comparing only the total dollar amount.

  2. 2

    Check for continuous water use

    Turn off intentional water use and check whether the meter continues registering consumption.

  3. 3

    Inspect toilets first

    A leaking toilet can consume water continuously without leaving visible water on the floor.

  4. 4

    Document repairs

    Keep plumber invoices, repair dates and photos when a leak or equipment failure caused unusual use.

  5. 5

    Request the City’s investigation

    Call the Revenue Office and explain that you believe the bill is unusually high and want the account reviewed.

Carbondale Code §16-3-5

Official published rules for investigation, adjustments and hardship installment agreements.

View Rule
09

Hardship option

Can You Get a Water Bill Payment Plan?

Carbondale’s published billing-adjustment ordinance allows an installment agreement when appropriate hardship circumstances exist, even when a bill adjustment itself is not granted.

Initial payment At least 10% Of total amount due
Remaining balance Monthly installments In addition to new monthly bills
Maximum schedule Up to 12 Payments under published rule
Frequency 1 per year Per account under current code
An installment plan does not replace new monthly bills.

The ordinance states that during the agreement period, the customer pays the scheduled installment plus the regular monthly utility bill. Missing required installments can affect continued service.

10

Avoid interruption

Past-Due Bill, Shutoff & Reconnection Rules

Important Carbondale delinquent-account rules in the published City Code
Issue Published rule What the customer should do
Due date City service agreements state bills are due 21 days after billing. Use the date printed on your actual bill.
Possible disconnect Outstanding balances can be subject to disconnection five calendar days after the payment due date. Call before the shutoff date if payment cannot be completed.
Disconnect notice The published code calls for notice at least five calendar days before proposed discontinuance. Do not ignore a shutoff notice.
Reconnect fee $40 under the currently published §16-3-6. Outstanding balance and applicable reconnect requirements must be satisfied.
Friday / holiday rule The published code states service will not be discontinued Friday or the day before a legal holiday. Still contact the City immediately; do not treat this as extra free payment time.
Service already off?

Carbondale Water Reconnect

The City’s online bill-pay area provides a separate reconnect-fee process for customers whose service has been interrupted for nonpayment.

Reconnect Options
Do not pay a past-due balance online and assume the water will automatically be restored.

Contact the Revenue Office at (618) 457-3265 when service is at risk or already disconnected so you know the amount and restoration process that apply to the account.

11

Long-term delinquency

Can an Unpaid Carbondale Water Bill Become a Property Lien?

Yes. Carbondale’s currently published utility code provides a lien process for qualifying unpaid water/sewer balances.

Timing

60 days

An outstanding utility balance can be deemed delinquent when it remains unpaid within 60 days of the billing due date.

Lien threshold

Over $100

The published ordinance states a lien will be filed against real estate with an outstanding balance exceeding $100.

Advance notice

At least 14 days

The code calls for notice before filing, including the amount due and information about bill-adjustment procedures.

Property owners should not ignore a tenant-related utility balance.

If you receive lien-related correspondence for a property, contact the City promptly and verify the exact account status, balance, adjustment rights and deadline.

Understand the bill

Carbondale Water Rates & Account Charges

Carbondale’s utility ordinance separates the bill into a monthly account charge and a consumption-based water rate. Wastewater service has its own charges.

Published FY2026 water-rate baseline effective with bills issued May 1, 2025
Water charge Published FY2026 amount
Residential/commercial water usage $5.25 per 1,000 gallons
5/8-inch meter monthly account charge $4.70
3/4-inch meter monthly account charge $4.70
1-inch meter monthly account charge $9.00
1½-inch meter monthly account charge $22.50
2-inch meter monthly account charge $22.50
Do not use the FY2026 baseline as an August 2026 quote.

The City ordinance requires water rates to be updated annually beginning May 1, 2026 using prior-calendar-year CPI guidance, subject to a 6% annual cap. Contact the Revenue Office for the exact rate currently applied to your bill.

New construction

New Water Tap vs. Opening an Existing Account

Existing property

Opening customer service

If a home or business already has a City water connection, use the residential or commercial service-connect process.

The normal residential account deposit listed by the City is $100.

New physical connection

Water tap / sewer connection

A new tap is a construction/utility connection project and has separate deposits, actual installation costs, permitting and zoning requirements.

Do not confuse a new-service customer deposit with a new physical tap deposit.

Examples of published water-tap deposits for new physical connections
Meter size Published deposit
5/8 inch$750
1 inch$800
1½ inch$2,600
2 inch$2,800
3 inch$3,800
4 inch$4,200

The ordinance says actual connection charges cannot be less than the City’s cost for materials, equipment rental and labor. Final costs can therefore differ from the initial deposit.

Water / sewer connection forms

The City provides tap applications and customer-service connection forms in its official Form Center.
