Huntsville Utilities

01

Service area: Huntsville and the Huntsville Utilities water service area, with Huntsville Utilities also acting as a billing agent for the City of New Hope water and sewer service

Dothan Utilities

01

Service area: Dothan and surrounding Wiregrass service area

Population: The City of Dothan describes this as a municipally owned and operated electric, potable-water, and wastewater utility serving Dothan and the southeastern Alabama Wiregrass area. The reviewed public pages do not publish a current system-population total, but the municipal service base plainly exceeds 3,300 residents and includes some adjacent customers and wholesale water recipients.

01

Service area: Tuscaloosa and the City of Tuscaloosa Water & Sewer Department service area

Population: The municipal water and sewer department serves the City of Tuscaloosa and its connected customers; the city’s population and university-centered service base place this system well above the 3,300-person threshold. The reviewed 2026 public pages do not provide a separate current population-served or connection-count figure.

Open utility profile
01

Service area: Greater Decatur area, including Decatur and routine resale customers in Hartselle, Limestone County, Northeast Morgan County, and Trinity

Population: Decatur Utilities’ public water-source material states that the system serves approximately 25,000 customers in all portions of Decatur and routinely provides water to the City of Hartselle, Northeast Morgan County Water District, Limestone County, and the Town of Trinity. The system therefore substantially exceeds the 3,300-person threshold; the customer count is more useful than a population conversion because it includes resale systems.

Alabama directory notes

How to compare water utilities in Alabama

This state hub brings together 77 indexed community water systems, from city departments and public authorities to investor-owned systems and smaller regional providers. A service area may cross municipal boundaries, so use the provider name and service address on your bill when choosing a profile.

The most important distinction is between a directory listing and an official account channel. Water Ledger provides a structured starting point; the utility’s own payment portal, published rate schedule, customer-service office, and mailed notice control your account. Compare the payment route, billing frequency, emergency number, and customer-protection notes before relying on a page for a time-sensitive decision.

If you are helping a household with a high bill, leak, or delinquency notice, open the utility profile and review the payment, shut-off, and leak-adjustment guides together. Keep the bill, account number, confirmation receipts, repair records, and notice dates available when speaking with the provider.
