Is water a renewable resource
Broadly speaking, water is a renewable resource, because the process of the water cycle, the polluted water can be evaporated, natural purification of the role of available water. Is a non renewable resource in narrow sense, as the city continues to accelerate the process, so that the water can not be normal circulation, sewage can not be good purification, such a vicious spiral, the water will be less and less.
Now the water is generally in the city building room is also the sewage into the sewage treatment plant will be unified, unified management of nitrogen and phosphorus removal, more clean water can be discharged into natural water can also be further processed by recycled water, recycled water (reclaimed water) so as to be back with the neighborhood. The industrial manufacturers generally have their own professional industrial wastewater treatment plant, after special treatment will be discharged to the municipal wastewater treatment plant with domestic sewage for further treatment.The water in nature is like a constant evaporation in the surface water, groundwater, water in the atmosphere, as well as the biological clock water cycle.
Of course, water is a renewable resource. Not to mention the regeneration of natural water resources.The water in the city, if you think it's not renewable, what do you think is the last thing the animal wastes?
