摘要: Nowadays, sustainable urban water management is a basic objective for the industry. In this context, key strategy to rationalize and energy demands since both resources are scarce precious. Their costs, including environmental ones, in average going up while requirements reduce greenhouse effect gases are, with passing time, also higher. These facts fully justify efforts manage more efficient way. This paper present methodology calculate losses linked leaks distribution systems its equivalent carbon credits (the amount of non emitted CO2 atmosphere obtained from saving water). To assess benefits reduction, two different scenarios (a network without leaks) considered. Carbon calculations performed using “Pacific Institute Water Air Models”. The method presented based energetic audit network, equation applied system. balance establishes that input energy, coming reservoirs pumps, equals useful delivered consumers plus lost pipes friction. As prerequisite, requires system mathematical model network. Simulations carried out EPAnet 2.0. Finally, show influence sources final results, four combinations From quantitative analysis, sensibility analysis can be easily it, adequate strategies whole cycle way, clearly identified.
