Em uma visão moderna, o sistema de drenagem deve ser tratado como um dos componentes do espaço urbano, sendo impossível dissociá-lo da infraestrutura das cidades. Para avaliar esses sistemas, os indicadores tradicionais (tais como aqueles baseados em cobertura de rede ou atendimento <em style="mso-bidi-font-style: normal;">per capita</em>) não são capazes de retratar sua condição (eficiência ou déficit). Esse artigo busca definir o conceito de déficit em drenagem e manejo de águas pluviais urbanas, tentando estabelecer as relações entre o conceito em si, as noções de risco utilizadas em dimensionamento de redes, a cobertura do sistema, as tecnologias para drenagem das águas pluviais, a informação disponível, o estado (de degradação) dos corpos d’água e as estruturas técnico-institucionais. Observa-se que a definição conceitual de déficit relacionado às águas pluviais é complexa e se relaciona a vários aspectos da infraestrutura e da política urbanas, não podendo estar restrito à cobertura de rede.</span></p> <!--[if gte mso 9]><xml> <w:LatentStyles DefLockedState="false" DefUnhideWhenUsed="true" DefSemiHidden="true" DefQFormat="false" DefPriority="99" LatentStyleCount="267">
