Environmental Sanitation means a wide range of interventions designed to
create and maintain an environment conducive to human health. This includes
sanitation (defined as the infrastructure and services required for the safe
management of human excreta) but also includes solid waste management, drainage
of surface water and sullage, vector control, air pollution control, etc.
(Greywater or sullage is defined as wastewater generated from plates and
wash-hand basins, showers and baths, which, because it is nearly as clean as
potable water, can be recycled onsite for uses such as toilet flushing,
landscape irrigation and constructed wetlands. Greywater often also includes
wastewater from clothes washing machines and sometimes include discharge from
dishwashers and kitchen sinks.)
