Understand Your CAW Bill: Water, Sewer, Sanitation, Taxes and Fees

A Little Rock customer may call it a water bill, but the monthly statement can include several different providers and line items. CAW/UBS handles billing and collection for multiple utility services, so the fastest way to solve a high bill is to identify which line actually changed.

💧

CAW water

Central Arkansas Water charges availability, monthly volume, infrastructure investment, watershed protection and other water-related line items.

♻️

Little Rock sewer

Little Rock sewer charges are from Little Rock Water Reclamation Authority, even when they appear on the combined CAW/UBS bill.

🗑️

Sanitation / solid waste

City of Little Rock solid waste charges can appear on the monthly statement and are separate from your water usage.

Bill line / partner
What it means
Who to contact
Central Arkansas Water
Drinking water service, meter reads, water volume charges, water fees and water service turn-on/turn-off.
CAW customer service: 501-372-5161.
Utility Billing Services / UBS
Collective billing name under which utility providers bill each month.

General sewer questions: 501-376-2903; sewer emergency: 501-223-1509.
Little Rock sanitation / solid waste
Garbage, recycling, yard waste and related solid-waste fees.
311 or 501-371-4437 for service; CAW/UBS for billing posting questions.
Franchise fees
Helpful information page lists franchise fees that apply to water/wastewater customers inside certain city limits.
Ask CAW to explain the city-specific franchise line item.
Sewer Service Line Replacement Fee
Monthly fee to Little Rock residential customers with 5/8-inch or 3/4-inch meter for LRWRA’s sewer service line replacement program.
Ask LRWRA about program details; ask CAW/UBS about how it appears on the bill.
Billing Services Fee
Monthly fee to fund replacement and maintenance of the customer information and billing system that serves water, wastewater and sanitation accounts.
Ask CAW/UBS for line-item explanation.
Taxes
Water and sanitation/refuse charges are subject to applicable state, county and city sales taxes.
Ask CAW/UBS to identify the taxable bill components.

High-bill clue: if the “water usage” line stayed normal but the total rose, check sewer, sanitation, taxes, franchise fees, prior balance, payment fees, deposit, reconnect fees and returned-payment charges before assuming the water meter is wrong.

High Little Rock Water Bill: Usage, Leak Adjustment and Meter Clues

📈

Check CCF and days

CAW billing periods run from prior meter read to current meter read. The number of days between readings appears on the bill.

💧

One-cycle leak adjustment

CAW’s leak adjustment policy offers a courtesy adjustment for only one billing cycle during a leak episode and is for water loss only based on average usage.

🧾

Repair proof needed

The leak form requests account details, leak discovery date, repair date, repair type and paid repair bill, receipts, photos or written repair statement.

High-bill check
What to do
Why it matters
Water usage in CCF
Compare prior and current CCF. Multiply CCF by about 750 to estimate gallons.
Understanding CCF helps compare usage month to month.
Billing days
Check the number of days between meter reads.
A longer billing period can raise total use even if daily use is normal.
Water vs sewer vs sanitation
Separate CAW water from LRWRA sewer, Little Rock sanitation, franchise fees, taxes and prior balances.
The total bill can rise from non-water line items.
Toilet leak
Dye-test toilet tanks and listen for refilling when nobody flushes.
Silent toilets can waste large amounts without visible water on the floor.
Irrigation / outdoor use
Check sprinkler controller, stuck valves, broken heads, hose bibs and seasonal watering.
Outdoor water can push the bill into higher residential CCF tiers.
Private plumbing
Check water heater, crawlspace, service line, ice maker, washing machine, pool fill and outdoor faucets.
Property owners/account holders are responsible for maintaining plumbing on the premises.
Leak adjustment form
Submit the one-time leak adjustment request with required repair documentation after leak repair.
Signing the form does not guarantee an adjustment, and payment responsibility remains.
Contact CAW early
Call customer service when abnormal activity is noticed.
CAW’s policy encourages customers to monitor accounts and contact staff immediately when abnormal use appears.

Leak-document checklist: keep paid plumber bill, itemized parts receipt, photos of repair, contractor/property-manager inspection note, or owner statement describing the leak, discovery date, repair date, location and corrected issue.

High-bill script: “My CAW/UBS bill increased from [normal CCF/amount] to [new CCF/amount]. I checked toilets, irrigation, water heater, crawlspace, outside faucets and the private service line. The leak was discovered on [date] and repaired on [date]. Can you explain whether I should submit a one-time leak adjustment and what amount must still be paid?”
