====Chile: Social tariff====
In Chile, poor families that cannot pay are eligible by law for a state-paid discount of 50% to 85% on their piped water supply and sewerage bill. The condition is that they have a ''social card'' from the Municipality. About 10% of the utility’s clients received the discount in 1994, which was valued at 2.5% of the total amount billed (Alfaro, 1997).
==Guidelines tariff setting water and sanitation==
The Water Partnership Program (WPP) of the African Development Bank produced guidelines (2010) on user fees and cost recovery for both non-networked and networked water and sanitation services in rural and urban areas. These guidelines can be used to develop water and sanitation tariffs.
