A sanitation system includes the capture, storage, transport, treatment and disposal or reuse of human excreta and wastewater. [4] Reuse activities within the sanitation system may focus on the nutrients, water, energy or organic matter contained in excreta and wastewater. This is referred to as the "sanitation value chain" or "sanitation economy".
An example of a wastewater treatment system. Sanitary engineering, also known as public health engineering or wastewater engineering, is the application of engineering methods to improve sanitation of human communities, primarily by providing the removal and disposal of human waste, and in addition to the supply of safe potable water.
Human waste (or human excreta) refers to the waste products of the human digestive system, menses, and human metabolism including urine and feces.As part of a sanitation system that is in place, human waste is collected, transported, treated and disposed of or reused by one method or another, depending on the type of toilet being used, ability by the users to pay for services and other factors.

Water coming from domestic equipment other than toilets (e.g., bathtubs, showers, sinks, washing machines) is called greywater. In some sanitation systems, it is preferred to keep the greywater separate from blackwater to reduce the amount of water that gets heavily polluted and to simplify treatment methods for the greywater. [citation needed]
Sustainable sanitation is a sanitation system designed to meet certain criteria and to work well over the long-term. Sustainable sanitation systems consider the entire "sanitation value chain", from the experience of the user, excreta and wastewater collection methods, transportation or conveyance of waste, treatment, and reuse or disposal.

For example, in 2015 it was reported that 68% of the world's population had access to improved sanitation. [ 3 ] In 2015 this goal was replaced by Sustainable Development Goal 6 , in which Target 6.2 states: "By 2030, achieve access to adequate and equitable sanitation and hygiene for all and end open defecation, paying special attention to the ...
