About 20% of energy in manufacturing is connected to refrigeration, heating water, the purpose of this research is to save environment by conserving water losses and these has to be replenished. Monitor rate of evaporation make up and blow down water superiority to authorize that the up-gradated structure is acting as predicted. Increasingly the most forward thinking using highly treated recycled water, side filtration, and option of ozone treatment, changing behavior of blow-down and replacing water saving equipment’s or modifying to reduce energy in addition water needs, which save budgets in addition recover water management in the future. This will address the problems found through an environmental review of current and future cooling systems, the technological, economic and environmental implications, with possible technical and non-technical solutions. Considering the current water crisis around the world, it is essential to expand the functions of these wet refrigeration towers to decrease their water consumption with maintaining their performance, therefore it has a great potential to recycle water evaporation. Which has not considered so far? This retrofit research using possible up-gradations at different research study, Reference [22] at existing facility regarding environment improvements (sustainability & water conservation) to perform a realistic evaluation of this idea. Experimental data measured and dynamic Eco approaches performed to evaluate the water saving potential. The result shows that water losses at one unit control from maximum (440) to minimum 108level to promote environment sustainability.
