What Makes Cinco Ranch's Water Unique?
Local geology and source profile
Cinco Municipal Utility Districts (MUDs), including Cinco MUD No. 1, No. 10, and No. 12, managed by Inframark, supply potable water to neighborhoods in Cinco Ranch, Katy, Texas, serving approximately 65,000 residents in Fort Bend and Waller Counties. The utility purchases groundwater from Cinco MUD No. 1, sourced from the Evangeline Aquifer. Treatment facilities operated by Inframark distribute water to areas including Cinco Ranch, Grand Lakes, and Cross Creek Ranch. Inframark can be reached at (281) 579-4500 for service inquiries.
The Evangeline Aquifer, part of the Gulf Coast Aquifer System spanning southeastern Texas, consists of unconsolidated sands, gravels, silts, and interbedded clays deposited in a Miocene-Pliocene deltaic environment. Groundwater percolates through underlying limestone, chalk, and dolomite deposits, dissolving calcium and magnesium ions. This carbonate-rich geology imparts a characteristically hard character to the supply, with elevated mineral content resulting from prolonged subsurface contact with soluble carbonate sediments and no dilution from surface water sources.
Hard water in Cinco Ranch promotes significant scale buildup in pipes, water heaters, dishwashers, washing machines, and faucets, potentially increasing energy costs by 20–30% and requiring frequent descaling. Regular vinegar flushes for appliances, installing sediment filters, and monitoring for white mineral residue are recommended maintenance steps. A water softener is strongly advised to extend equipment life. Independent analysis rates overall water quality C+, with an A for legal compliance but C for health guidelines; 10 contaminants are noted as exceeding health advocacy levels per that analysis.

Data Sources & Methodology
Water quality data for Cinco Ranch is derived from geographic and geological modelling of the surrounding region. No federal monitoring station data was available for this location.
Water Hardness
Modelled estimate based on state-level USGS geological survey data for this region. No direct USGS Water Quality Portal measurement was matched to this city — the value reflects a statistical range calibrated to the state's dominant rock types and typical source water characteristics.
pH
Estimated from regional geology and source water characteristics. pH is correlated with water hardness and local bedrock — values may differ from utility-reported figures.
TDS — Total Dissolved Solids
Estimated using a derived ratio from water hardness and regional conductance profiles. TDS in natural water correlates strongly with total mineral content including hardness ions.
PFAS — Perfluoroalkyl and Polyfluoroalkyl Substances
EPA UCMR5 (5th Unregulated Contaminant Monitoring Rule, 2023–2025) — sum of PFAS compounds detected at the public water system serving this city. A value of 0 indicates the system was sampled with no detection above reporting limits.
Lead
Modelled estimate based on the EPA Lead and Copper Rule 90th-percentile tap-sample methodology. No publicly available per-city lead dataset with sufficient national coverage exists. Values are a conservative baseline derived from city population tier and infrastructure age — all estimates are maintained below the EPA action level of 0.015 mg/L.
Appliance Lifespan
Calculated from water hardness using a linear degradation model. Baseline lifespans represent soft-water performance (kettle: 8.5 yrs, washing machine: 12.0 yrs, water heater: 15.0 yrs). Hard water mineral scale progressively reduces operational life in direct proportion to hardness concentration.
