Exercise begins in the early morning hours. Frequent users in gym gear choose to start the day with physical exertion. Walking, running, outdoor gym, biking, soccer and volleyball are just some of the options available. All this takes place on the shores of nine interconnected lagoons, the wetlands. The project developed by Architectus S/S has turned a ­formerly degraded area into a bustling, lively, pulsating public space.

Occupying one of the city’s flooded preservation areas, the Rachel de Queiroz Park project adopted the drainage system as a structural element. Wetland management was used to improve the water quality of the Riacho Cachoeirinha stream, as well as to create a flood mitigation system. After intensive hydrological studies, nine interconnected ponds were proposed to perform natural water filtration by means of decanting and phytoremediation, a process performed by microorganisms fixed both on the surface of the soil and on the roots of aquatic plants in the ponds. In other words, in addition to its landscape potential, wetlands are a fundamental strategy for the environmental restoration of the area, without excluding the uses required by the local community.
