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.

This research is aimed to study both the species diversity and utilization of plants at the Baan Tah Tongdeang community forest Nabot Wangchao districtTak province. The survey of plant species and the available quantity has been carried out using the quadrat method. The leaders and intellectuals in the community were interviewed using a structured questionnaire. The result showed that the plant with the highest Density (D) and Relative Density (RD) were Tectona grandis L.f. (0.734375/m2 7.742998353) Xylia xylocarpa Taub. var. kerrii Nielsen (0.6875/m2 7.248764415) Grewia eriocarpa (0.65625/m2 6.919275124) respectively. Whilst plant with the highest Frequency (F) and Relative Frequency (RF) were Xylia xylocarpa Taub. var. kerrii Nielsen Grewia eriocarpa and Holoptelea integrifolia Planch. (87.5 4.96) Tectona grandis L.f. and Schleichera oleosa (Lour.) Oken (75 4.26) Pterocarpus macrocarpus Kurz and Bombax anceps Pierre (62.5 3.55) respectively. The Shannon and Wiener’s diversity index (H’) of trees was 3.38 while evenness index was 0.85. The utilization of the plants in the community included 94 species as wood (used as plank furniture firewood charcoal string chemical extraction etc. 62 species as medicinal herbs 47 species as wild vegetables fruits and foods. All of them are utilized in the community. The results of this research would be beneficial for administrative and management as a guideline to preparation a community biological database and learning resources for conservation and sustainable uses of natural resources and environments in Baan Tah Tongdeang community forest.
