A questionnaire survey on 397 random farmers from all the villages of the Sivakasi taluk is used as a tool for the data collection (Table 1). The survey is carried out by the authors of this paper between August 2021 and December 2021. The questionnaire survey focuses on four components (i) socio-economic profile of the farmers, (ii) satisfaction of water supply, (iii) agricultural factors, and (iv) the WTU the TWW for agriculture and the WTP for the reuse. The farmers confirmed that the variables taken into consideration in the questionnaire (Table 1) are sufficient and significant to cover several issues related to the agricultural water management.
