Water of a quality suitable for drinking. ... Water Treatment Plant. A facility that treats water to remove contaminants so that it can be safely used.

The specific gravity indicates how much heavier or lighter a material is than water. It is the ratio of the weight of a given volume of material to the weight of an equal volume of water. If a particle has a specific gravity greater than one, it means that it has a weight heavier than water and it will eventually settle in still (quiescent) water.

Furthermore, wastewater can include any used water and water-carried solids from a community that flows to a treatment plant, such as stormwater, surface water, and industrial water. Fact: 99 percent of wastewater is just dirty water; the other 1 percent is solids, chemicals, nutrients, fats, and other pollutants. Screening

The homogeneous sand filter has a 0.9–1 m deep bed of typically 0.85–1.7 mm sand (d 10 =0.9 mm) placed on a 50 mm layer of 4–8 mm or 75 mm of 6.7–13.2 mm gravel. Homogeneous sand of effective size up to 1.3 mm has also been used. The stated size ranges for sand and gravel are generally 5 and 95 percentiles.
