Utilities in Polk County

THE WATER LIST IS FROM THE FEDERAL DRINKING WATER DATABASE, not from a directory. All 56 systems were read out of EPA's Safe Drinking Water Information System through Envirofacts on 2026-09-08, filtered to active community water systems whose identifier begins TX187 — the state's code for Polk County — and each row's connection count, population served, water source and PWSID is exactly as the federal record has them. Those figures are as of each system's last report and are not live. THE TWO ALABAMA-COUSHATTA SYSTEMS WERE ADDED ON 2026-09-09 AND WERE MISSING BEFORE THAT. The original query filtered on identifiers beginning TX187, the state's code for Polk County, which by construction cannot return a tribal system: the Tribe is sovereign and its water is regulated by the EPA's Region 6 office, so both systems carry federal identifiers beginning 06 and Texas deactivated its own records for them in 1993. They were found by querying EPA's Envirofacts for systems with Region 6 primacy, and both are recorded there as active community water systems drawing groundwater. THE EAST SIDE POPULATION FIGURE IS FLAGGED ON THE PAGE RATHER THAN REPEATED AS FACT: 4,104 people against 155 connections is about 26 per connection and cannot be households; it reads as a daily service population. The Tribe publishes its own annual water quality report for each system and those are linked; they, not this page and not the state, are the authority on that water. No contact details are published for either system in the federal record and none are invented here. SUPPLIERS WERE ADDED ON 2026-09-09 AND ARE SOURCED THREE WAYS. Sixteen systems are Lake Livingston Water Supply Corp.'s: its own subdivisions page lists them and the federal record gives all sixteen the same office number. Twelve more are named organizations with their own websites, each of which was opened and confirmed to be the Polk County body it claims to be. Six are corporations with an active registration but no site of their own, so the row links the Public Utility Commission's record instead. THE REMAINING TWENTY ARE MARKED NOT CONFIRMED rather than guessed at: they are small private systems with no website and no active PUC registration, and the federal record's contact for them is often an individual's own number, which is not published here. A phone number is shown only where the system is an institution. TWO SUPPLIED LINKS WERE WRONG AND ARE NOT USED: a page offered for Dallardsville Segno WSC belongs to St. Tammany Parish, Louisiana, and a link for Oakridge North returned a 404 — the parent site, Lake Livingston Water Supply Corp., is used for that system instead. A third trap worth recording: rcwsc.myruralwater.com is Robertson County WSC, not Polk County's R.C. WSC, and is not linked. MYTAPWATER.ORG IS LINKED AS A READER TOOL, NOT AS A SOURCE. Nothing on this page is taken from it. Its own about page states it compiles data published by federal, state and local agencies, chiefly the EPA, and it carries an affiliate disclosure, so it is described here as the commercial site it is. Its per-system address pattern was tested against ten of the 56 systems, including the smallest, and all eight resolved. NATURAL GAS COMES FROM THE RAILROAD COMMISSION'S OWN TABLE 1A, Natural Gas Service to Texas Cities, read on 2026-09-09. It names all three suppliers and all seven served places in the county. That table was compiled in 2022, so the customer counts are several years old and are shown to give a sense of scale rather than as current figures. Propane dealers are not gas utilities, are not licensed as such, and are not listed. ONALASKA'S WATER AND GAS RATES, hours, addresses and emergency numbers are from the corporation's own site on 2026-09-09. LIVINGSTON IS FULLY SOURCED from the city's own department pages: the 1922 founding, the two substations on two Entergy lines, the 75 miles of 13 kV line, the customer counts, the billing dates and the 1978 Trinity River Authority water contract. EASTEX AND HIGHLINE are each from their own sites, including Highline's Texas service-area list, which names Livingston, Goodrich and Leggett; note that coverage within a named town is still address by address, which is why the FCC lookup is offered. ENTERGY'S numbers are from its own contact page. SAM HOUSTON ELECTRIC COOPERATIVE IS STILL NOT CONFIRMED: its website returns errors to every automated request from here, so its address, phone numbers and hours are what is published about the co-op elsewhere and are marked accordingly; its own outage map does load and is linked. NOT VERIFIED: which addresses fall in Entergy's territory versus the co-op's, which is why this page says to read your bill rather than drawing a line on a map.
