Cooling water recovery from water distillation equipment was a research that has the objective to restore the cooling water from distillation equipment which installed at textile chemistry technology department laboratory at Textile industrial and fashion design in Rajamangala University of Phra Nakorn. The research plan was designing and developing the water distillation equipment type cyclon ultrapure water stills model WSC008 of Fistreem company. The outcomes found the designed system could save the tap water consumption 3462.72 square meters per year. That was implied 7617.64 Bath per year of tap water consumption could be save what the tap water consumption rate was 2.22 Bath per square meters. This system was paid back in 3.33 years and the benefit-cost ratio for single project (B/C ratio) was 1.26 (>1). Finally this project was successfully to save the tap water consumption and great benefit investment.

Pure water was consumed and insufficient that causes from the population continuous increasing. The water was contaminated with some pollutants. The most of science laboratory produced only the distillation water for experimental learning. In present distillation technology was released a lot of wastewater. Therefore a research group interested in applies to use value engineering for water resource management. This research collected the data analysis of distillation water process and designed of renewable wastewater for cooling process. The results shown that before improve system a distillation water and wastewater were found 3.7 l/h and 140.3 l/h respectively. For after improve system a distillation water was found only 3.82 l/h and without wastewater. Furthermore economical study found that the cost of water and electric were saved 394.23 bath/month when compared with old system. And the payback period was 114.16 month (9 years 6 months 3 days). Hence the applied value engineering for water resource management could be saved wastewater 100 percent.
