Fuzzy Evaluation of Agricultural Water Conservancy Facilities in Reuse

2. Literature Review

Pescod investigated few case studies for wastewater and TWW reuse, recycle and their effects on soil, human health, and crop yield and production (Walaa A., et al.,. 2019). Al-Aama and Nakhla) investigated the cost of TWW reuse for landscape irrigation in Jubail, Saudi Arabia. Crook and Surampalli (Singh B., et al., 2008; Sharma A., et al., 2019) compared the criteria of TWW reuse in several States in the USA. Rathee G., et al., 2020) demonstrated that water conservation, reuse and recovery measures in the natural gas and crude oil sectors alone had the potential to conserve up to 222 MCM/year of water in Saudi Arabia. The study showed that the increase in secondary wastewater treatment and reuse might result in substantial cost and energy savings for six inland cities, while an estimated 26% of urban water needs could be met by such TWW (Kajenthira et al. 2011). Qadir et al. (2010) summarized the production, treatment and irrigation by TWW in the Middle East and North Africa (MENA) region. The authors have shown that the MENA region has high potential of beneficial reuse of Treated waste water, while some of the major constraints for slow progress are as follows:
