Changes

'''[[Tariffs]]''' are funds contributed by users of W water, sanitation and hygiene services for obtaining the service ([[#GLAAS|GLAAS]], 2012). Users generally make payments to service providers for getting access to the service and for using the service. When the service is self-provided (e.g. when a household builds and operates its own household latrine), the equity invested by the household (in the form of cash, material or time, sometimes referred to as ''sweat equity'') would also fall under tariffs.
