SUMMARY:Reuse of reclaimed water coming from a centralized treatment plant for domestic septic tanks wastewater
DESCRIPTION:Reuse of reclaimed water coming from a centralized treatment plant for domestic septic tanks wastewater\n\n		\n	\n\n	\n		\n			\n\n		\n	\n\n	\n		\n			 \nWaste water source\nThe wastewater treatment plant receives water with some sludge from individual septic tanks and from a small collective wastewater treatment installation. \nWater input quality is : \n\nCOD : 5 to 25 g/l\nSuspended Solids : 5 to 50 g/l\nNTK : 400 to 800 mg/l\,\nPt: 70 to 300mg/l\n\n  \n\n		\n	\n\n	\n		\n			 \nDistribution System\nThe reclaimed water is stored in a 140 m³ storage tank before primary treatment. Then water is distributed via a pressurized piping system that is around 2 km long to the plots. Irrigation is then performed using nozzles and micro-sprinklers delivering one feeding point for each tree. \n\n		\n	\n\n	\n		\n			 \nFarming system\nForestry plantation (poplar and eucalyptus). \n\n		\n	\n\n	\n		\n			 \nWaste water treatment description\nNutrient removal : Treatment on reeds beds with a total surface area of 2\,600 m².\nPesticide removal : none\nDisinfection : none\nSuspended solids removal : Primary treatment with a central grooved disc filter.\nOther : \n\n		\n	\n\n	\n		\n			 \nCapacity\nThe system produces 6\,300 m³ of reclaimed water each year. \n\n		\n	\n\n	\n		\n			 \nExtent of the agricultural beneficiaries\nThe area irrigated with reclaimed water is about 3.2 ha. \n\n		\n	\n\n	\n		\n			 \nCosts\nThe investments cost is 1.72 million euros\, while the maintenance cost comes at 31\,000 euros/year. The energy expenses add up to 14\,000 euros. \n\n		\n	\n\n	\n		\n			 \nType of agreement\nNot applicable as  the fields belong to the community which is as well the owner of the WWTP. The fields supply firewood to the communal heat production plant. \n\n		\n	\n\n	\n		\n			 \nScientific results\n\n		\n	\n\n	\n		\n			 \nAdditional information\nThis project has several environmental benefits such as reducing sludge transport (100 to 120 km per day)\, avoiding direct discharge and reducing surface water withdrawals.
