One of the projects was carried out in the town of Analandia, Sao Paulo, Brazil and wetlands with floating aquatic plants associated to the HDS system were used. Nearly 6480 inhabitants were supplied. The other conducted project was an experimental station in partnership with SABESP (Sao Paulo State Sanitation Agency/Brazil), for the pretreatment of 1700 l.s-1 of waters from the Cotia River, which is used for the population's supply after conventional treatment at the Lower Cotia Water Treatment Station. For this pilot project, wetlands with emergents and floating plants associated to the HDS system were used. The proposed objectives were achieved in both projects.203-210engAquatic plantsConstructed wetlandsDownflow bedsFiltering soilPublic water supplyVertical flow systemFiltering soilsHydric depuration with soilsVertical flow systemsDeveloping countriesPlants (botany)Reservoirs (water)RiversSoilsSurface water resourcesWater filtrationWater qualityWater supply systemsWetlandsWater treatmentBrazilconference paperwater supplywater treatmentTrabalho apresentado em evento10.1016/S0273-1223(99)00411-4Acesso aberto2-s2.0-0032821006
