The project of improvement of the residential area of the favela in Brasilia is made in the form of a three-dimensional layout using the following materials. The project provides layouts of public toilets. They are painted with white, brown and pink acrylic paint. Next to the toilets, trees -birches, maples - are planted at a distance of 5-7 meters. These trees pull up to 200 liters of water out of the ground in 24 hours. This solution significantly reduces sewage waste water. Drinking taps should be provided on the streets of favelas.
