Sewerage and Wastewater treatment

Water quality protection and responsible wastewater treatment contributes to the improvement of environmental conditions. Sweco Hydroprojekt‘s activities span across the complex issues related to waste water collection and treatment on the municipal and industrial level. In addition to the design of new Wastewater Treatment Plants (WWTP), we provide services related to the modernization and expansion of existing WWTPs which at the present time do not comply with emission limits as per European legislative. We place great emphasis on the environmental safeguarding of WWTPs, reduction in their energy consumption requirements and increasing the efficiency of control systems.

Collection, treatment and disposal of sewage water needs to be done in such a way to avoid endangering human health and prevent the degradation of surface and ground water resources. Conceptual design of disposal of waste water from an urbanized basin is called a drainage master plan. The dynamic development of built-up area requires the most detailed description and evaluation of the existing situation to create a complete model with the most accurate inputs to allow detailed design required a prospective solution. At present, so-called integrated approach that considers all drainage elements and processes for wastewater treatment in context is implemented.

Sweco Hydroprojekt solves waste water of sewage and rainfall character by systematic way and with the most efficient use of available tools and resources to create sustainable water management of particular area.
