Liquid waste management

Liquid waste management will include both onsite sanitation and offsite treatment and disposal methods. The most usual method of onsite liquid waste containment in rural areas is the pit latrine. Pit latrines are simple drop-and-store systems in which the liquid waste collects in a pit below. There are many different designs of pit latrine:

In places where water is more easily available, typical methods are drop-flush-and-discharge systems, also known as water carriage systems, such as the pour-flush latrine or a water closet (WC).

Wastewater from water carriage systems may be piped into a septic tank or into a community or municipal treatment system, if one exists.
