Curitiba still has slums filled with poor people but the city has a social charter designed to help them. The slum dwellers have to cope with regular floods. The slums will be cleared but to solve this Curitiba has used Site and Service schemes, where the government offers low interest loans on the land and free house design for the people. The residents are trained to build the houses and make up a large part of the labour force. The houses have electricity, sewerage and running water.
