| Abstract | This study was result for assign and designs appropriate the disposal systems of human excreta in Thawatchaburi district, Roi-Et province. The analysis of three different disposal systems of human excreta (Cesspools system, the septic tank with soakage pit, and the septic tank with anaerobic filter) from LCA tool shows that impact potential from the septic tank with anaerobic filter which is damage to human health 13.2 milli-points (6.77E-10 DALY), Ecosystem quality 2.34 milli-points (3.00E-05 PDF*m2yr), and Resource 21.9 milli-points (6.14E-04 MJ surplus) that was bigger than the other systems. It was result assessment from and Eco-indicator 99 part, it should select cesspools because it had least damage to global. But in the other part, the cesspools does not suitable because had many problem into human health and high cost (16,820-46,820 baht) per one life time of the disposal systems of human excreta (50 years). Thus the system suitable for local people is the septic tank with soakage pit because it considers in damage categories from LCA it had damage to human health 7.60 milli-points (3.89E-10 DALY), Ecosystem quality 1.31 milli-points (1.69E-05 PDF*m2yr), and Resource 13.6 milli-points (0.00038 MJ surplus) and the lowest cost (including initial cost and operation cost = 8,165-18,165baht). Thus the system is suitable and appropriate with the local in the rural area is the septic tank with soakage pit. Because of this system had low cost for installation and damage to global a little score. |
