Industrial Water Demand Prediction Model by Using Input-Output Table: The Case of Industrial Strategy of Thailand and Impacts from Pricing Policy

In this paper, impacts of target industrial growth rate from economic scenarios and governmental option scenarios are estimated. There are two main scenarios. The first case is with and without subsidy cost by governmental agencies and the second is case of with and without new water infrastructure. Water demand management model is analyzed by using input-output table, water use unit analysis, water supply analysis, and integrated water management. The suitable government option which should be implemented with minimum impact to the target growth rate is a case of subsidy cost by government with new water infrastructure. The impacts from this proposed option is –0.006 % from 9.7 % industrial target.
