1. Scope of Services
In the case of groundwaters, the scope of our services covers:
- planning of hydrogeological investigation and adequate reports
- evaluation of ground water reserves
- dewatering of mining operations and other engineering constructions.
- ground water intakes for industrial and municipal purposes.
- impact of industrial and municipal waste disposals on the ground water quality
- protection of ground water against harmful effects on human activities
- monitoring systems
including the designs of drainage wells of different types and character, water intake wells, piezometric tubes, ground water flow modeling etc.
2. An offer:
- analyses, opinions
- feasibility reports
- basic and detailed designs
- site supervision
3. Executive Potential
The hydrogeological team consist of highly skilled staff hydrogeologists and engineers. At each phase of planning and designing, the computer technique is used and the available software enables simulation of ground water seepage processes, optimization of design options, and control of large dewatering systems and water pumping operation. To this end, digital hydrogeological databases with operational features of designed system are applied to determine spacing between wells, time of ground water draw-down, volume of pumped water etc.
The team is fully equipped with computers and working stations. AutoCad and Micro-Station software are used to prepare graphic materials. Forecasts and analyses of the quantitative and qualitative ground water protection are done using the most sophisticated software, including SURFER, GRAPHER, Aquifer Test and mathematical simulation methods (programs MODFLOW, MT3D).
4. The most important references:
