SUMMARY:Demonstration of vineyard irrigation with reclaimed water
DESCRIPTION:Demonstration of vineyard irrigation with reclaimed water\n\n		\n	\n\n	\n		\n			IRRI ALT’EAU\n\n		\n	\n\n	\n		\n			 \nWaste water source\nDomestic wastewater is treated by the wastewater treatment plant of Narbonne Plage which is operated by Veolia. A second wastewater treatment plant has been considered but finally aborted because of a high salinity content due to saltwater intrusion into the sewage network. \n\n		\n	\n\n	\n		\n			 \nDistribution System\nReclaimed water is distributed through a pipe network to the plots. \n\n		\n	\n\n	\n		\n			 \nFarming system\nReclaimed water beneficiaries are intensively cultivated vineyards (wine production). \n\n		\n	\n\n	\n		\n			 \nWaste water treatment description\nNutrient removal : Wastewater is treated using a bio-filter for nutrient removal\, followed by filtration.\nPesticide removal : none\nDisinfection : In order to fulfill different water quality standards\, two processes have been implemented. At first UV disinfection\, followed by chlorination to achieve B quality. One the other hand\, only chlorination is used to achieve C quality.\nSuspended solids removal : none\nOther \n\n		\n	\n\n	\n		\n			 \nCapacity\nThe Narbonne plage wastewater treatment plant has an average discharge of 650 m³/day. However\, as a touristic area\, volumes increase drastically during the summer period. \n\n		\n	\n\n	\n		\n			 \nExtent of the agricultural beneficiaries\nThis project is divided into several stages. The experimental stage 1 involves 1.5 ha of the INRA research center of Pech Rouge. Stage 2’s objective is to investigate the effect of reclaimed water irrigation on water\, and the soil and plant interaction. The aim of stage 3 is to upscale the beneficiaries by supplying 80 ha of vineyards. This area produces grapes for the cooperative winery of Cave de Gruissan. \n\n		\n	\n\n	\n		\n			 \nCosts\nThe total cost of the project is 1.7 million euros. The cost of the reclaimed water is yet unknown. \n\n		\n	\n\n	\n		\n			 \nType of agreement\nThe initiative has an explorational status. The consortium set up a consortium agreement between the project partners. \n\n		\n	\n\n	\n		\n			 \nScientific results\nPeer-reviewed papers and conferences: \nchebarne\, F.\, Aveni\, P.\, Escudier\, J.-L.\, & Ojeda\, H. (2019). Reuse of treated wastewater in viticulture: Can it be an alternative source of nutrient-rich water? BIO Web of Conferences\, 12\, 01009 \nSeveral studies have been performed during that project in order to highlight a potential contamination from reclaimed water to the final product and soil quality. Those studies concluded to the following results:\n(1) No impact on wine quality\n(2) No impact on soil or groundwater quality\n(3) Concentration of micropollutants below drinkable water limit\n(4) No disinfection by-products\n(5) Yield increase due to nutrient input \n\n		\n	\n\n	\n		\n			 \nAdditional information\nStage 1 & stage 2 are implemented and have been operational for several years. Funds are required for stage 3 upscaling. \nhttps://www.actu-environnement.com/ae/news/irrignation-vignes-eaux-traitees-station-epuration-25154.php4#video&xtor=EREC-107 \nhttps://suwanu-europe.eu/wp-content/uploads/2019/11/10_Irrialteau-présentation-du-projet-12_4_7-1.pdf
