Rainwater harvesting systems in buildings can also contribute to the management of stormwater runoff reducing flood peaks. These technologies should be enhanced in Mediterranean countries where water scarcity is increasing and the occurrence of extreme events is becoming very significant, as a result of climate change. An extensive pilot GR with three aromatic plant species, Satureja montana, Thymus caespititius and Thymus pseudolanuginosus, designed to study several parameters affecting rainwater runoff, has been in operation for 12 months. Physico-chemical analyses of roof water runoff (turbidity, pH, conductivity, NH4+, NO3\u2212, PO43\u2212, chemical oxygen demand) have shown that water was of sufficient quality for non-potable uses in buildings, such as toilet flushing. An innovative approach allowed for the development of an expression to predict a \u2018monthly runoff coefficient\u2019 of the GR system. This parameter is essential when planning and designing GRs combined with rainwater harvesting systems in a Mediterranean climate. This study is a contribution to improving the basis for the design of rainwater harvesting systems in buildings with extensive GRs under a Mediterranean climate.<\/jats:p>","DOI":"10.2166\/wst.2016.034","type":"journal-article","created":{"date-parts":[[2016,1,22]],"date-time":"2016-01-22T22:23:47Z","timestamp":1453501427000},"page":"1842-1847","update-policy":"https:\/\/doi.org\/10.2166\/iwapcrossmarkpolicypage","source":"Crossref","is-referenced-by-count":36,"title":["Contributions to the design of rainwater harvesting systems in buildings with green roofs in a Mediterranean climate"],"prefix":"10.2166","volume":"73","author":[{"given":"Cristina M.","family":"Monteiro","sequence":"first","affiliation":[{"name":"CBQF\u2013Centro de Biotecnologia e Qu\u00edmica Fina\u2014Laborat\u00f3rio Associado, Escola Superior de Biotecnologia, Universidade Cat\u00f3lica Portuguesa\/Porto, Rua Arquiteto Lob\u00e3o Vital, Apartado 2511, 4202-401 Porto, Portugal"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Cristina S.
