Waste Water Use - the Environmental Safety of Crimea

Abstract

The purpose is to assess the volume and quality of wastewater treatment in terms of the feasibility of using it to irrigate crops. Methods. General geographical and generally accepted mathematical and statistical methods were used in the research. Results and discussion. On the basis of the analysis of the quantitative component of the waters formed in the territory of the Republic of Crimea, the most promising sources are sewage treatment facilities of the cities of Simferopol, Yalta, Evpatoria, Alushta, Feodosia, Kerch, Dzhankoy. For the future, it is advisable to consider using the sewage treatment facilities of Bakhchisaray, Novoozernoye ("Donuzlav") and Belogorsk as an alternative source of irrigation water, with the volume of generated wastewater being 0.5-1 million m3/ year. The best salt quality is found in treated wastewater from the towns of Simferopol, Alushta, Sudak and Belogorsk (water suitable for irrigation purposes), while the worst is in Yevpatoria, Kerch and Novoozernoye ("Donuzlav"). Wastewater should be stored in the autumn-winter period, if possible using existing empty water storage facilities, and then used in the irrigation season.
