\u0130zmir\u2019in en \u00f6nemli su kayna\u011f\u0131 olan Tahtal\u0131 Baraj\u0131, son y\u0131llar\u0131n en kurak d\u00f6nemlerinden birini ya\u015f\u0131yor. Barajdaki su miktar\u0131, tarihinin en d\u00fc\u015f\u00fck seviyesine gerileyerek 1.65\u2019e kadar d\u00fc\u015ft\u00fc. Bu seviye, 2008 y\u0131l\u0131ndaki b\u00fcy\u00fck kurakl\u0131kta \u00f6l\u00e7\u00fclen 1.90 seviyesinin de alt\u0131na inmi\u015f durumda. Ekim ay\u0131nda ise \u0130zmir genelinde 81 kilogram ya\u011f\u0131\u015f kaydedilmesine ra\u011fmen, barajdaki su seviyesinde belirgin bir art\u0131\u015f g\u00f6zlemlenmedi. Uzmanlara g\u00f6re bunun nedeni, uzun s\u00fcren kurakl\u0131\u011f\u0131n ard\u0131ndan ilk ya\u011f\u0131\u015flar\u0131n b\u00fcy\u00fck b\u00f6l\u00fcm\u00fcn\u00fcn kuru toprak ve bitkiler taraf\u0131ndan emilmesi. Ayr\u0131ca mevsim normallerinde Kas\u0131m, Aral\u0131k, Ocak ve \u015eubat aylar\u0131nda ortalama 119 kilogram ya\u011f\u0131\u015f d\u00fc\u015f\u00fcyor. Her kurak d\u00f6nemim ard\u0131ndan bol ya\u011f\u0131\u015fl\u0131 bir d\u00f6nem geldi\u011fini aktaran T\u00fcrkiye Bilimler Akademisi (T\u00dcBA) \u00c7evre, Biyo\u00e7e\u015fitlilik ve \u0130klim De\u011fi\u015fikli\u011fi \u00c7al\u0131\u015fma Grubu \u00dcyesi Prof. Dr. Do\u011fan Ya\u015far, bu d\u00f6nemlerde ya\u011f\u0131\u015flar\u0131n ekim ay\u0131ndaki gibi ya\u011f\u0131\u015f miktar\u0131n\u0131n yakla\u015f\u0131k 2 kat\u0131na ula\u015fmas\u0131 halinde Tahtal\u0131 Baraj\u0131\u2019n\u0131n doluluk oran\u0131n\u0131n y\u00fczde 20 seviyelerine kadar \u00e7\u0131kabilece\u011fini belirtti.<\/p>\n

2009-2019 y\u0131llar\u0131 aras\u0131nda Tahtal\u0131 Baraj\u0131 doluyken durumun iyi oldu\u011funu vurgulayan Ya\u015far, “\u00d6zellikle ge\u00e7en sene neredeyse hi\u00e7 ya\u011fmur ya\u011fmad\u0131, \u00e7ok az ya\u011f\u0131\u015f ald\u0131k. Bu durum yaln\u0131zca \u0130zmir\u2019de de\u011fil, b\u00fct\u00fcn Bat\u0131 Anadolu\u2019da ya\u015fand\u0131. Her yerde tehlike \u00e7anlar\u0131 \u00e7al\u0131yor. Ancak \u0130zmir\u2019in \u00f6nemli bir fark\u0131 var; kentin suyunun b\u00fcy\u00fck k\u0131sm\u0131 yer alt\u0131ndan sa\u011flan\u0131yor. 15-20 y\u0131l \u00f6nce 40-50 metreden \u00e7ekilen yeralt\u0131 sular\u0131 bug\u00fcn 450 metreye kadar d\u00fc\u015ft\u00fc. 2022\u2019de bile baraj doluluk oran\u0131 y\u00fczde 60\u2019lardayd\u0131. Ancak buna ra\u011fmen yer alt\u0131 suyunun \u00e7ekilmeye devam edilmesi akiferlerin t\u00fckenmesine yol a\u00e7t\u0131. Bu gidi\u015fle 2035\u2019ten sonra benzer bir kurakl\u0131k ya\u015fand\u0131\u011f\u0131nda yer alt\u0131ndan su 1000-1200 metre derinliklerden \u00e7ekilmek zorunda kalacak. Bu da \u00e7ok b\u00fcy\u00fck enerji harcamas\u0131 demektir. Zaten \u0130zmir\u2019in T\u00fcrkiye\u2019de en pahal\u0131 su kullanan \u015fehir olmas\u0131n\u0131n nedeni budur. \u0130zmir\u2019i rahatlatacak en \u00f6nemli ad\u0131mlardan biri, \u00c7i\u011fli Ar\u0131tma Tesisi\u2019nden \u00e7\u0131kan gri suyun tar\u0131ma kazand\u0131r\u0131lmas\u0131d\u0131r. Bu tesis g\u00fcnde 500 bin metrek\u00fcp su \u00fcretiyor. Bu su ar\u0131t\u0131larak Menemen ve Gediz ovalar\u0131na verilmelidir. B\u00f6ylece bu b\u00f6lgelerde yeralt\u0131 suyunun \u00e7ekilmesi durdurulabilir, akiferlerin yeniden dolmas\u0131 sa\u011flanabilir. Gerekti\u011finde bu kuyular yeniden kullan\u0131labilir ve \u0130zmir\u2019in su kaynaklar\u0131 s\u00fcrd\u00fcr\u00fclebilir hale getirilebilir” dedi.<\/p>\n

“E\u011fer bir yerde d\u00fczenli su kesintileri ba\u015flat\u0131lm\u0131\u015fsa, bu orada suyun t\u00fckendi\u011fi anlam\u0131na gelir. Ancak su kesmek siyasi bir ba\u015far\u0131s\u0131zl\u0131k de\u011fildir; suyun siyaseti olmaz. \u015eu anda gece 23.00 ile sabah 05.00 aras\u0131nda yap\u0131lan kesintilerle yakla\u015f\u0131k 100 bin metrek\u00fcp su tasarrufu sa\u011flan\u0131yor. Ge\u00e7en y\u0131l ayn\u0131 d\u00f6nemde \u0130zmir\u2019e 680-700 bin metrek\u00fcp su verilirken, \u015fu anda bu miktar 580 bin metrek\u00fcp civar\u0131nda. Asl\u0131nda bu uygulamaya ge\u00e7en y\u0131ldan ba\u015flanm\u0131\u015f olsayd\u0131 durum biraz daha rahat olabilirdi. Ekim ay\u0131nda ya\u011f\u0131\u015flar \u00e7ok iyi ge\u00e7ti, y\u00fczde 100\u2019e yak\u0131n art\u0131\u015f oldu. Ancak barajlara etkisi hemen g\u00f6r\u00fclmez. \u00c7\u00fcnk\u00fc \u00f6nce toprak doymal\u0131d\u0131r. 52 y\u0131l\u0131n en kurak d\u00f6neminin ard\u0131ndan toprak suya a\u00e7t\u0131r. \u00d6nce toprak suyu emer, ard\u0131ndan bitkiler al\u0131r, kalan su barajlara ula\u015f\u0131r. Bu nedenle barajlarda aral\u0131k ay\u0131n\u0131n 10-15\u2019ine kadar b\u00fcy\u00fck bir art\u0131\u015f beklenmemelidir. Aral\u0131k sonunda y\u00fczde 3\u2019l\u00fck bir art\u0131\u015f g\u00f6r\u00fcl\u00fcrse iyi say\u0131l\u0131r. Barajlar\u0131n dolum d\u00f6nemi nisan ortas\u0131na kadard\u0131r. E\u011fer o tarihte y\u00fczde 20 doluluk oran\u0131na ula\u015f\u0131l\u0131rsa bu \u00e7ok iyi, y\u00fczde 25 olursa ola\u011fan\u00fcst\u00fc bir ba\u015far\u0131 olur. Ya\u011f\u0131\u015flar elbette gelecektir ama belediyeye tavsiyem, su kesintilerini bir y\u0131l daha s\u00fcrd\u00fcrmeleri ve gece kesinti saatlerini biraz daha uzatmalar\u0131d\u0131r.”
