Water geo-filtration around, under or through the constructions and equipment is one of the most important environmental factors that influence their durability, endurance and exploitation conditions. In natural environments geo-filtration takes place everywhere and at any time. Therefore, during the processes of planning, building and exploiting buildings and equipment it is necessary to know the most important parameters of geo-filtration, such as present and anticipated levels and depths of ground water, geo-filtration rates, velocity and directions. The calculations results and their accuracy depend on the correctness and accuracy of initial input data and the formation of the model of modelling territory. Data is filled the intersections of the rectangle mathematical net, which covers modelling territory. The mathematical net should be chosen so that the input data in the intersections forms a calculation model as close as possible to reality. If the initial input data of the model differs from reality, the results of calculations will inaccurate.
