Small water retention reservoirs
Using small water retention reservoirs is a concept that is becoming more and more important in the context of highly urbanized areas. The activities carried out as part of “small water retention” are an antidote to many problems that modern cities grapple with. Urban floods, increasing sewage system operations costs, lower sewage system capacity, surface water pollution, and breaking the natural water cycle, are only some of the worrying phenomena that are gaining relevance. The reason for this relevance is quite prosaic, while the losses incurred by cities and the environment are complex.
