SUMMARY:Water reuse project of Hersonisos. Reclaiming municipal wastewater for the irrigation water of olive trees
DESCRIPTION:Water reuse project of Hersonisos. Reclaiming municipal wastewater for the irrigation water of olive trees\n\n		\n	\n\n	\n		\n			Life initiative (2009-2013)\n\n		\n	\n\n	\n		\n			 \nWaste water source\nThe wastewater is of urban origin coming from the municipality of Hersonisos located in Northcentral Crete. The wastewater treatment plant receives wastewater from three settlements: ‘Hersonisos’\, ‘Piskopiano’ and ‘Koutoulofari’. The wastewater treatment plant is located at the West of the ‘Hersonisos’ town\, approximately 0.8 km from the city limits. \n\n		\n	\n\n	\n		\n			 \nDistribution System\nThe existing network for the distribution of treated water to olive cultivation exceeds 50\,000 meters. \n\n		\n	\n\n	\n		\n			 \nFarming system\nThe wastewater treatment plant’s effluent is used for irrigation of olive groves. \n\n		\n	\n\n	\n		\n			 \nWaste water treatment description\nNutrient removal :  Conventional municipal wwtp techniques to remove phosphate and nitrate\nPesticide removal : none\nDisinfection : Chlorination and UV disinfection\nSuspended solids removal : Sand filtration\nOther : \n\n		\n	\n\n	\n		\n			 \nCapacity\nThe wastewater treatment plant of Hersonisos is designed for a population equivalent of 40.000. Its average annual capacity is 2\,475 m³/day with the maximum capacity reaching 5\,297 m³/day.  The total quantity of treated water available for olive-tree irrigation amounts from 3\,000 to 12\,000 m³ on a daily basis (there is a relevant permit). More than 2\,500\,000 m³ of treated water is earmarked annually for olive-tree irrigation. \n\n		\n	\n\n	\n		\n			 \nExtent of the agricultural beneficiaries\nServed users are over 1\,200. The irrigated area reaches 12\,000 acres of olive cultivation\, with more than 150\,000 olive trees. The annual production of olive oil varies from 1\,000 to 2\,500 tons. \n\n		\n	\n\n	\n		\n			 \nCosts\nInvestment cost for the wastewater treatment plant is € 5\,538\,224. The reclaimed water is provided to farmers free of charge. \n\n		\n	\n\n	\n		\n			 \nType of agreement\n\n		\n	\n\n	\n		\n			 \nScientific results\nPapadopoulos\, I.\, Costa\, C. N.\, & Savva\, G. (2009). Sustainable Use of Treated Wastewater in the Agricultural Field. \n\n		\n	\n\n	\n		\n			 \nAdditional information\nFuture goals for the municipality of Hersonissos concerning the reuse of treated waste water are:\n1. Improvement of water quality at the outlet to enable irrigation of vegetables and generally edible vegetables.\n2. Possibility of enriching aquifer from the outflow of the wastewater treatment plants.\n3. Harmonization with the requirements of legislation on the re-use of treated water.\n4. Improvement and extension of the irrigation network for the use of treated water in more areas.\n5. Development of a new management plan for the irrigation network.
