Population: 186,738 residents in Brownsville (2020 U.S. Census; the Census Bureau QuickFacts page reports a 2020 estimate base of 186,331). BPUB's public water page describes service to Brownsville and surrounding areas, so the city population is used as a conservative public proxy rather than claiming an unsupported exact CWS population.

Population: Approximately 66,500 residents in the City of Victoria (U.S. Census Bureau July 1, 2025 estimate); the City budget reports approximately 23,440 water customers and 22,121 sewer customers in its most recently published utility operating data.

Service area: Cedar Park and connected areas of the Cedar Park utility service area

Population: The City’s water-utility code estimates the 2024 water service-area population at approximately 101,648; the Census Bureau estimates Cedar Park city itself at approximately 78,380 residents in 2024. The utility bills city water, wastewater, trash, and certain district-related charges, so the billing footprint is larger than the city’s residential population alone.

Service area: Flower Mound

Population: Approximately 81,925 residents in the Town of Flower Mound in 2025 according to the Town’s demographics page; the Town’s 2025 utility presentation reports approximately 26,465 water accounts and 23,100 sewer accounts.

Population: Approximately 68,316 residents in the City of Pflugerville according to the U.S. Census Bureau July 1, 2025 estimate. The City’s 2026 water-shortage declaration identifies approximately 64,193 water customers and essential community facilities, which is the better operational service-population measure for the retail system.

Service area: Wylie and adjacent Collin/Dallas County service areas

Population: The EPA SDWIS profile for PWS TX0430011 lists 48,393 people served; the City of Wylie’s July 2025 Census estimate is 63,842 residents, and the FY2026 utility budget reports approximately 17,600 monthly water, sewer, and trash accounts.

Service area: Allen and the City of Allen water and wastewater service area

Service area: Baytown and the City of Baytown water, sewer, garbage, recycling, and drainage service area

Population: PWS TX1010003 is a Community Water System serving approximately 83,701 people in the latest published state-organized system listing; an EPA-linked profile has also reported 72,312 in an earlier data vintage. Baytown’s city population is approximately 84,000, so the current system should be treated as a roughly 84,000-person municipal service area.

Service area: City of Katy municipal water, sewer, and garbage service area

Population: EPA SDWIS PWS TX1010017 identifies CITY OF KATY as an active Community Water System, local-government owned, serving approximately 25,253 people in Harris County. The system is a municipal provider and does not represent every surrounding Katy-address MUD or private district.

Population: EPA-linked PWS TX0190004, TEXARKANA WATER UTILITIES, is a Community Water System serving approximately 39,678 people.

Service area: Mansfield and the City of Mansfield water-utility service area in Tarrant County

Population: EPA-linked PWS TX2200018, CITY OF MANSFIELD, is reported as a Community Water System serving approximately 68,612 people. The City’s fiscal planning documents separately estimate the broader municipal population at a higher figure, so the SDWIS system population is used here for the drinking-water system estimate.

Service area: Cleburne and the City of Cleburne water, sewer, and sanitation service area in Johnson County

Population: EPA-linked PWS TX1260003, CITY OF CLEBURNE, is reported at approximately 30,573 people by the current EPA-derived utility profile. Other Texas project records show population figures around 31,352–34,075 depending on reporting year and boundary, so 30,573 is retained as the current system estimate with the reporting variation noted.

Service area: Midlothian and the City of Midlothian retail water and wastewater service area in Ellis County

Population: EPA-linked PWS TX0700005, CITY OF MIDLOTHIAN, is reported at approximately 21,450 people in the current EPA-derived utility profile. Other public records show lower historical snapshots, including approximately 16,728, so the current profile estimate is retained with the expected reporting-year variation.

Service area: Kerrville and the City of Kerrville municipal water, sewer, and garbage service area in Kerr County

Population: EPA-derived current utility records identify CITY OF KERRVILLE as a Community Water System serving approximately 23,489 people. Public profile snapshots vary, including approximately 21,450–26,000 depending on reporting year and system boundary; the current estimate is retained as a drinking-water-system figure rather than the City’s total regional population.

Service area: Sherman and the City of Sherman water, wastewater, trash, and stormwater service area in Grayson County

Population: EPA-linked PWS TX0910006, CITY OF SHERMAN, is reported at approximately 43,645 people in current Texas Water Development Board and EPA-derived records. The City’s wastewater permit separately identifies about 44,000 Sherman collection-system residents; the drinking-water-system estimate is retained as 43,645.

Service area: Wichita Falls and the City of Wichita Falls retail water, wastewater, refuse, and stormwater service area in Wichita County

Population: EPA-derived PWS TX2430001 (CITY OF WICHITA FALLS) serves approximately 102,316 people in current SDWIS-derived public records. The City’s current AMI materials also identify approximately 34,000 retail meters and the Water Distribution page reports more than 35,000 active meters, so the customer-meter count and population estimate represent different measures.

Service area: Harker Heights and the City utility service area in Bell County, including inside- and outside-CCN customers

Population: EPA-derived public water system TX0140023 (CITY OF HARKER HEIGHTS) serves approximately 34,834–35,957 people in the latest publicly indexed records. The City’s 2024 water-quality report projects a build-out population of about 45,000, so the current served estimate and long-range planning number should not be conflated.

Service area: Denison and the City of Denison water, wastewater, and refuse service area in Grayson County, including inside- and outside-city customers

Population: EPA/Texas public-water records identify City of Denison PWS TX0910003 with an estimated population served of approximately 24,872; a 2020 public-water funding record listed 22,682. The City’s 2020 Census population was approximately 24,479, so the directory should treat 24,872 as the current indexed system estimate rather than a guaranteed current census count.

Service area: Ennis and the City of Ennis water, wastewater, and garbage service area in Ellis County

Population: EPA-derived public records identify CITY OF ENNIS PWS TX0700001 serving approximately 24,891 people. The City’s 2020 Census population was about 20,159 and the system serves Ennis and nearby Palmer-area customers in indexed utility records, so the PWS population is the appropriate water-system estimate rather than the city-limit census figure.

Service area: Palestine and the City of Palestine water, wastewater, and solid-waste service area in Anderson County

Population: EPA-derived public-water records identify City of Palestine PWS TX0010001 and approximately 24,891 people served. The Census Bureau estimates the City of Palestine at 19,555 people in 2025, so the PWS figure can include service-area customers beyond the incorporated population.

Service area: Paris and the City of Paris water, wastewater, and residential solid-waste service area in Lamar County, including Reno-area customers served by the system

Population: Texas Water Development Board’s SFY2026 public-water funding list identifies City of Paris PWS TX1390002 with approximately 24,476 people served. The City’s utility office reports services for nearly 10,000 households each month, while the PWS population includes the broader water service area.

Service area: Waxahachie and the City of Waxahachie water, wastewater, and related utility service area in Ellis County

Population: The EPA/TCEQ-indexed public-water record for PWS TX0700008 reports approximately 33,021 people served. Current Census city estimates are approximately 50,090 and current indexed water-quality sources vary up to roughly 50,814, so the PWS figure is used as the direct utility-system estimate and the city estimates are contextual.

Service area: Seguin and the City of Seguin municipal water and wastewater service area in Guadalupe County

Population: An indexed 2026 water-quality record for City of Seguin PWS TX0940001 reports approximately 32,736 residents served.
