BLS metro-level wage data places Water and Wastewater Treatment Plant and System Operators pay in Texarkana, TX-AR at a median of $39,260 per year ($18.88/hr/hour), drawn from the OEWS May 2025 release for this Metropolitan Statistical Area. Compared to the national median of $60,020, Texarkana pays 35% below, which typically tracks with a lower local cost of living or smaller specialized-employer cluster. Approximately 40 water and wastewater treatment plant and system operatorss are employed across the Texarkana MSA in SOC 51-8031.

The Texarkana pay distribution spans from $33,830 at the 10th percentile to $54,840 at the 90th — a 1.6× spread that reflects experience tenure, specialization, employer size, and the difference between public-sector, nonprofit, and private-sector compensation inside the metro. The 25th percentile sits at $38,240 and the 75th at $46,860, so half of Texarkana-based water and wastewater treatment plant and system operatorss earn within that middle band.

Metro figures capture where you actually work, not just where you live — which matters for commuters. BLS draws metro boundaries from the OMB MSA definitions, so Texarkana, TX-AR covers the central city plus outlying counties tied to the metro economically. Remember that OEWS wages reflect base pay only: employer-provided health insurance, retirement matches, stock options, signing bonuses, overtime, and tips are excluded and can add 20-40% to real total compensation. Before using this metro median as a negotiation anchor, triangulate against the same occupation's national profile (linked below), its state-wide TX data, and peer-metro comparisons — a median is a starting point, not a ceiling.
