Utilização de solos residuais para infiltração de águas residuais tratadas
Silva, Flora; Albuquerque, António; Arrobas, Margarida; Cavaleiro, Victor; Marecos do Monte, Helena; Scalize, PauloA reutilização de águas residuais tratadas (ART) é praticada, na maioria dos casos, como uma estratégia de conservação da água em regiões onde os recursos hídricos são escassos, mas também por motivos ambientais, a fim de se preservar a qualidade da água de meios recetores, reduzindo a descarga de efluentes de estações de tratamento de águas residuais (ETAR). Nos próximos anos, a região da Beira Interior (Portu...
Site selection for reclaimed water infiltration using GIS tools
Silva, Flora; Albuquerque, António; Marecos do Monte, Helena; Cavaleiro, Victor; Carvalho, AntónioIn the Beira Interior region (Portugal) some sources of water do not present characteristics suitable for some uses due to pollution (namely associated to the discharge of point and nonpoint effluents) or are over-exploited (namely the aquifers). However, the water demand will grow in this region to meet socio-economic activities under development (e.g. the Cova da Beira irrigation plan, irrigation of golf cour...
Analysis of reclaimed water application for irrigation using multi-criteria ana...
Albuquerque, António; Marecos do Monte, Helena; Silva, Flora; Cavaleiro, Victor; Carvalho, AntónioApproximately 60% of the population of the Cova da Beira region (Portugal) lives in rural communities with less than 2,000 inhabitants and the wastewater treatment plants (WWTP) in the region are mainly septic tanks, constructed wetlands and trickling filters. The daily reclaimed water discharged into streams could be mainly reused for landscape irrigation of public parks and lawns and golf courses, which often...
Evaluation of the groundwater quality in the Alcochete area using GIS
Cavaleiro, Victor; Casinhas, Cláudio; Albuquerque, António; Carvalho, António; Silva, FloraMost of the water needed for domestic, agricultural, recreational and industrial activities in the Alcochete municipality (Portugal) comes from groundwater sources. However, doubts remain on the state of its quality and attractiveness for the current uses. A monitoring campaign was set in 67 groundwater sources (26 wells and 41 boreholes) for the period of 4 months to evaluate the water quality status. In order...
Estado da qualidade da água de origem subterrânea no concelho de Alcochete com ...
Cavaleiro, Victor; Casinhas, Cláudio; Albuquerque, António; Carvalho, António; Silva, Flora; Sanderson, A.M. LeitãoA maior parte da água necessária para atividades domésticas, agrícolas, lúdicas e industriais no concelho de Alcochete (Portugal) provêm de origens subterrâneas. Contudo, subsistem dúvidas sobre o estado da sua qualidade e a sua apetência para as utilizações atuais. O estudo da hidrogeoquímica permite estabelecer relações entre o meio aquoso e o meio geológico, refletindo a influência da litologia local e dos s...

Site selection for reclaimed water infiltration using GIS tools
Silva, Flora; Albuquerque, António; Marecos do Monte, Helena; Cavaleiro, Victor; Carvalho, AntónioIn the region of the Beira Interior some sources of water do not present characteristics suitable for some uses due to the discharge of not well treated effluents or because are over-exploited (namely aquifers). However, the water demand will grow in this region to meet socio-economic activities under development (the Cova da Beira irrigation plan, irrigation of golf courses and green areas, spas and distributi...

Application of GIS-based multi-criteria analysis for site selection of aquifer ...
Pedrero, Francisco; Albuquerque, Antonio; Marecos do Monte, Helena; Cavaleiro, Victor; Alarcon, JuanReclaimed water from small wastewater treatment facilities in the rural areas of the Beira Interior region (Portugal) may constitute an alternative water source for aquifer recharge. A 21-month monitoring period in a constructed wetland treatment system has shown that 21,500 m3 year−1 of treated wastewater (reclaimed water) could be used for aquifer recharge. A GIS-based multi-criteria analysis was performed, c...
Localização de áreas para infiltração de águas residuais tratadas de pequenos a...
Silva, Flora; Albuquerque, António; Cavaleiro, Victor; Marecos do Monte, HelenaNa região da Beira Interior algumas origens de água não apresentam características compatíveis com algumas utilizações, devido a fenómenos de poluição (descarga de efluentes) ou por se encontrarem sobre-exploradas. Contudo, as necessidades de água tenderão a crescer nesta região para satisfazer as exigências de actividades sócio-económicas, o que implicará a procura de recursos hídricos alternativos. Após uma c...
