Design & Engineering – rather complex and multidimensional process. This development of a conceptual object the functioning of the scheme, including portion of the study, hydraulic calculations, power supply system, the balance of the equipment with a miscalculation of technical parameters, as well as details of the calculation for the plants precipitation. The accuracy and literacy project depends on the quality of the future work of the system. Therefore, the design is necessary to entrust a highly qualified specialists who will be able to prepare all the necessary working documents, and will be responsible for the design solutions developed.
