Water designated for human consumption as drinking water may be subject to specific drinking water quality standards.

Wastewater (or waste water) is water generated after the use of freshwater, raw water, drinking water or saline water in a variety of deliberate applications or processes. [1]: 1 Another definition of wastewater is "Used water from any combination of domestic, industrial, commercial or agricultural activities, surface runoff / storm water, and any sewer inflow or sewer infiltration".

The Safe Drinking Water Act is the principal federal law governing public water systems. [1] These systems provide drinking water through pipes or other constructed conveyances to at least 15 service connections, or serve an average of at least 25 people for at least 60 days a year. As of 2017 there are over 151,000 public water systems. [2]

[45] Generally, water management agencies are reluctant or unwilling to give a concrete definition to a relatively vague concept of water ...
