Water scarcity is a worldwide problem, which leads to unprecedented pressure on water supply in arid and semi-arid regions. Treated wastewater is an alternative water resource, therefore, its reuse for agricultural irrigation has been growing worldwide since the beginning of the 21st century. In several regions of wine-producing countries (e.g., Australia, California – USA, Spain), wastewater reuse appears to be the most accessible alternative, both financially and technically, for agricultural uses that notably do not require drinking water. From the summer of 2022, vine irrigation full-scale implementation will start with tertiary treated municipal wastewater in the French Languedoc region. This was made possible thanks to a collaborative research project conducted between 2013 and 2018 to address all potential health and environmental risks associated with this process. This research project was conducted in the south of France, with experimental and control plots both equipped with drip irrigation systems. All the results produced during the research project demonstrated the feasibility of applying this process for vine drip irrigation while effectively managing health and environmental risks and complying with the regulation. A social acceptance and economic study were also performed in order to broaden the scope of the project scalability evaluation.

水资源短缺是一个世界性问题，导致干旱和半干旱地区的供水面临前所未有的压力。处理后的废水是一种替代水资源，因此，自 21 世纪初以来，其用于农业灌溉的再利用在世界范围内不断增长。在葡萄酒生产国的一些地区（例如澳大利亚、美国加利福尼亚州、西班牙），对于不需要饮用水的农业用途，废水再利用似乎是最经济和技术上最容易实现的替代方案。从2022年夏季开始，法国朗格多克地区将全面实施采用经过三级处理的城市废水进行葡萄树灌溉。这要归功于 2013 年至 2018 年期间开展的一项合作研究项目，该项目旨在解决与此过程相关的所有潜在健康和环境风险。该研究项目在法国南部进行，试验地块和对照地块均配备了滴灌系统。研究项目期间产生的所有结果都证明了将该工艺应用于葡萄藤滴灌的可行性，同时有效管理健康和环境风险并遵守法规。为了扩大项目可扩展性评估的范围，还进行了社会接受度和经济研究。研究项目期间产生的所有结果都证明了将该工艺应用于葡萄藤滴灌的可行性，同时有效管理健康和环境风险并遵守法规。为了扩大项目可扩展性评估的范围，还进行了社会接受度和经济研究。研究项目期间产生的所有结果都证明了将该工艺应用于葡萄藤滴灌的可行性，同时有效管理健康和环境风险并遵守法规。为了扩大项目可扩展性评估的范围，还进行了社会接受度和经济研究。
