Operation of economic and other objects within the boundaries of water protection zones is allowed only under the condition of ensuring protection of water bodies, environmentalists warn. Another violation of the Water Code of the Russian Federation near the Stepnoy Zai River was discovered by inspectors of the South-Eastern Territorial Administration of the Ministry of Ecology and Natural Resources of the Republic of Tatarstan. Construction trailers belonging to one of the Almetyevsk companies were installed in the water protection zone in the absence of special facilities for discharge of wastewater, including rainwater, snowmelt, irrigation water and drainage water.
