What a Waco or McLennan County home needs depends on which system serves it, and whether it is on a public supply or a private well. The assessment comes first, then the recommendation.
Softening and carbon filtration on the main line, so it reaches every tap in the house rather than one fixture. Sized after we read your water report.
An under-sink stage with its own faucet for drinking and cooking water. It works on dissolved solids, which matters more on some systems here than others. Woodway reports average total dissolved solids of 584 mg/L.
For homes on private wells, common around Crawford and China Spring. There is no published annual report for a private well, so the starting point is a screening rather than a document.
