This emerging paradigm is based on the premise that urban waters are the lifeline of cities and the focus of the movement towards more sustainable "green" cities. The concepts of the new sustainable urban water management systems and the triple bottom line (TBL) criteria by which their performance will be judged are summarized and outlined. The paradigm considers microscale green development concepts and links them with macroscale watershed management, water/stormwater/wastewater infrastructures and landscape preserving or mimicking nature. Urban water management of the future ecocities may be based on implementing interconnected semiautonomous water management clusters. In the sustainable urban development the macroscale TBL measures of sustainability must be considered. The new systems will combine sustainable water conservation and reuse infrastructure and ecologically and hydrologically functioning landscape. Concepts and fundamental building blocks of ecocities are presented and discussed.

A high percent removal for a control will usually occur if the initial concentration is high. Separate and combined stormwater flows exhibit wide variability from storm to storm as well as within a given storm. The effect of initial concentration on performance can be evaluated directly by finding the order of the reaction as well as the rate constant (Heaney and Wright 1997).
