The χ2 test is used to analyze the statistical significance of agricultural factors (type of land, source of irrigation, and method of irrigation) on the WTU and WTP (Table 4). The type of land has no significant influence on WTU. It is noted from the analysis that irrespective of the type of land, whether it is rainfed or wetland, the farmers have WTU the TWW for agriculture. This is due to the fact that almost all the farmers require an alternative source of water for irrigation because of the water scarcity in the area. More than 90% of the farmers confirm the prevailing water scarcity in the area. The farmers prefer to reuse the TWW for agriculture rather than leaving the land barren. However, to date, the farmers are unaware of the potential use of TWW for agriculture.
