Applying the Best Available Technologies concept in the substantiation  of the system of engineering protection of natural water from pollution

Summary

The contemporary science-methodical and regulatory base supposes the wide application of the Best Available Technologies principle including the implementation of environmental protection activities. As a result of studies and model simulations three basic causes of underground and surface water pollution on the considered territory of the Sosnovsk oil deposit in the Samara Area were identified: fracking that includes discharging produced and waste water into the stratum; industrial waste leakages from cushion holes and service wells; leakages from distribution pipelines and tanks with the subsequent filtration through the aeration zone into underground and surface waters. A mathematical model of underground water filtration with establishing a specialized information system was developed. Simulating filtration in operating strata where industrial wastewater is pumped provides for evaluating the pressure of the stratum and, consequently, the so-called adverse effect level that is determined by the ratio of the pressure in the stratum to the fracking pressure. The calculations of underground water filtration were carried out both under stationary and non-stationary conditions with the use of MODFLOW Model. The basic conceptual framework of the Best Available Technologies principle as applied to the problem of desi­gning the systems of engineering protection of underground and surface water from pollution is presented. The example of implemen­ting the presented conceptual framework in the location of landfills for produced and waste water discharges in the Samara Area is given. It was determined that the best option shall be chosen on the basis of the business and economic calculations.

Numerical Simulation for Substantiation of the Engineering Protection System in the City of Kazan

Summary

It is told about the process of creating a software package for numerical simulation of the drainage system in the city of Kazan. The calculations to determine the optimal mode of its operation are presented. The problem of optimizing the operating mode of pumping stations is formalized and presented as a problem of multicriterion optimization: reducing the potential damage as a result of underflooding at minimization of energy costs. The decision has been found with the help of an evolutional algorithm. On the basis of calculations carried out the recommendations for optimization of the pumping stations operation mode in the city of Kazan making it possible to reduce expenditures for operation of the engineering protection system for preservation of urban territories from underflooding have been given.
