Today in Laishevo launched purification biological facilities after a large-scale reconstruction. The last repair work on the site was carried out in 1989. The opening ceremony was attended by the Minister of Ecology of Tatarstan Alexander Shadrikov, the Director of the Gasification Fund of the Republic of Tatarstan Jaudat Minnahmetov and the head of the Laishevsky district of the republic Mikhail Afanasyev. The design capacity of the facility is 450 cu. m drains per day. Now before the discharge of sewage into the natural reservoir of water, they have to overcome several stages of purification. Contaminated water undergoes biological treatment with the help of special bacteria. As a result, it is cleared at 95 - 98 percent. According to the head of Laishevsky district, it is planned to build the second phase of the facility. In the next few days, the treatment facilities in Tarlovka, Bazarnyi Mataki and Mamadysh will also be commissioned after the reconstruction. In 2018, the budget of the republic allocated 167 million rubles for the repair of the BTF in Biryulyakh, Novosheshminsk, Rybnaya Sloboda, Buinsk and Karabash.
