Central Arkansas Water Rates and Charges for 2026

CAW’s published water rate schedule became effective for water billed on or after January 1, 2026. Rates differ for properties inside and outside Little Rock and North Little Rock city limits.

The water bill includes an availability charge based on meter size and a volume charge based on water consumption. One CCF, or hundred cubic feet, is approximately 750 gallons.

2026 Residential Availability Charges

2026 Residential Water Usage Rates

These amounts apply to CAW residential water charges, not the entire combined utility bill. Infrastructure investment fees, watershed protection fees, wastewater charges, sanitation fees, taxes and other applicable items can increase the total.

For additional meter sizes and customer classes, consult the official 2026 CAW rate schedule.

Why Does My Little Rock Water Bill Include Sewer or Trash Charges?

CAW’s Utility Billing Services also handles billing functions for participating wastewater and sanitation agencies. Receiving these charges on the same statement does not mean CAW operates every service.

• Water service: Central Arkansas Water.
• Little Rock wastewater: Little Rock Water Reclamation Authority.
• Solid waste and sanitation: The applicable city or local sanitation provider.
• Billing services fee: Supports the shared utility billing and customer information system.

Little Rock residential sewer charges may also depend on Average Winter Consumption, calculated from water use during the October–March period. If your sewer amount appears unusually high, compare it with the winter consumption shown on your statement.

For sewer-related questions, visit Little Rock Water Reclamation Authority.

Start, Transfer or Stop Water Service in Little Rock

Moving into a house or apartment? Contact Central Arkansas Water before the move-in date so the account and meter can be handled correctly.

Start Water Service at an Existing Property

1. Read CAW’s Start or Stop Service instructions.
2. Call Customer Service at 501-372-5161 or toll-free 855-742-0309.
3. Provide the service address, requested start date and identification or account details requested by the utility.
4. Ask about the deposit and activation charge before finalizing the request.
5. Confirm whether someone needs to be present when water is turned on.
6. Verify the account is active before relying on the service.

CAW publishes a $20 activation fee, added to the first month’s bill, for establishing service where facilities are already in place.

New customers generally need a security deposit equal to approximately two months of average billing. Depending on credit history, the deposit may be included on the first bill.

Transfer Service to Another Little Rock Address

If you are moving within the CAW service area, ask whether your existing deposit can transfer to the new location.

CAW states that it may allow overlapping service at the old and new addresses for up to two weeks to help with a move. Confirm eligibility and account dates with Customer Service.

Stop Water Service

1. Contact CAW Customer Service.
2. Give the service address and requested final service date.
3. Provide a forwarding mailing address.
4. Ask how the final bill and any refundable deposit will be handled.
5. Keep the confirmation and review the closing statement.

CAW says residential deposits are refundable after 12 consecutive months of on-time payments. When an account closes, a deposit may also be applied toward the final bill.

New Construction Without an Existing Meter

For a property that has never had water service, contact the New Service Section at 501-210-4910 or email newconstruction@carkw.com.

New construction may require permits, engineering review, meter installation or other charges. These are separate from the standard existing-service activation process.

Little Rock Water Utility Customer Service and Emergency Numbers

Use the correct number for your problem. A payment question, water main break and wastewater backup may require different departments.

Fix Common Little Rock Water Billing and Service Problems

Water Bill Is Much Higher Than Normal

A sudden increase can come from plumbing leaks, running toilets, irrigation, longer billing periods or changes in consumption.

Start with these checks:

1. Compare your current and previous month’s CCF usage.
2. Check toilets, faucets, outdoor taps and irrigation systems.
3. Review your online usage history for unexpected increases.
4. Arrange repairs if a leak is found.
5. Contact CAW to ask about its one-time leak adjustment program.

Request a Water Leak Bill Adjustment

Central Arkansas Water has an official courtesy leak adjustment process. A qualifying adjustment applies to one billing cycle during a leak episode, subject to utility review.

To request a review:

1. Repair the leak and record when it was discovered and fixed.
2. Gather plumber invoices, receipts, repair photographs or other accepted documentation.
3. Open the official one-time leak adjustment form.
4. Enter your account details, service address and repair information.
5. Upload the required repair documentation and submit the request.

CAW reviews requests under its leak adjustment policy. Submitting the form does not guarantee an adjustment or remove responsibility for the bill.

Cannot Afford an Overdue Water Bill?

CAW partners with Promise to offer flexible payment arrangements for customers with overdue balances.

According to its published program, residents and businesses owing $50 or more on their CAW water bill can explore a payment plan.

1. Open CAW’s Promise payment plan website.
2. Provide the account information requested.
3. Review the available payment arrangement.
4. Accept the plan terms if appropriate.
5. Make scheduled payments and keep your regular CAW account current.

Customers who keep both their CAW account and Promise plan current receive the protections described in the program terms, including protection from water disconnection related to the covered balance.

Another possible local resource is the Central Arkansas Development Council (CADC), which CAW references for utility assistance. Contact CADC at 501-326-6229 to ask about current assistance availability.

No Water or Low Pressure at Your Address

Before reporting a water outage, check whether the issue affects the whole property or just one fixture.

• Check whether nearby homes have water.
• Look for planned interruptions on CAW’s outage map.
• Use the map’s address search to focus on your neighborhood.
• Call the water main dispatch line if there is a suspected break.
• Use the after-hours emergency number for urgent situations.

Check Central Arkansas Water outages ↗

Fall 2026 local notice: CAW has published hydrant testing and inspection information for parts of North Little Rock, Maumelle and Sherwood during October–November 2026. If you notice temporary pressure or water appearance changes near testing activity, verify the official notice or contact CAW rather than assuming it is a citywide outage.

Water Appears Cloudy, Brown or Unusual

Water discoloration can have different causes, including local main work or sediment disturbance. It does not automatically mean the water is unsafe, but unusual odor, color or an active advisory should be taken seriously.

For water-quality concerns, contact CAW at 501-223-1574. Follow any current official boil-water or safety advisory and do not rely on general troubleshooting advice when a health warning is active.

Who Handles Water, Wastewater and Trash in Little Rock?

The name printed on a combined bill can cause confusion. Different providers may operate the underlying services even when they share a billing system.

For billing questions involving multiple services on the same statement, start with CAW Utility Billing Services. For an actual sewer overflow, contact the wastewater utility directly.
