While exact methods can vary, here’s a general breakdown of the municipal wastewater treatment process:When wastewater leaves a home or business, it is transported through municipal collector pipelines usually by the force of gravity, to a wastewater treatment plant. If gravity flow is not available all the way, then a lift station may pump the wastewater up to a level where gravity flow can again take place.As wastewater enters the treatment plant, it is screened to remove non-sewage items suc...

Sedimentation in water treatment is a process in which water is cleaned by allowing solids to settle out of the water by gravity during treatment.

Mineral water is naturally occurring or prepared water that contains dissolved minerals, elements or gasses, often used therapeutically. Several Brazos River basin towns built industries around local mineral water and its purported healing powers towards the end of the nineteenth century. Those cities included Mineral Wells, Marlin, Waco and others.

Total dissolved solids, or TDS, are the amount of minerals that remain when a water sample is completely evaporated, such as the water spots on your glassware.  TDS is a measurement of all organic and sometimes inorganic solids in water and is reported as milligrams per liter (mg/l). TDS includes elements and organic compounds such as calcium, magnesium, potassium, sodium, bicarbonates, chlorides, and sulfates.  TDS is used as a general indicator of water quality.

Brackish is a term used to describe water that contains more dissolved minerals (see total dissolved solids) than normally acceptable for municipal, domestic and agricultural uses. It has a higher amount of dissolved solids than fresh water but not as high as saltier types such as seawater.Brackish water includes concentrations of total dissolved solids (TDS) ranging from 1,000 to 10,000 milligrams per liter (mg/l).
