Run-off wastewater management2007-12-22
Run-off wastewater shall be rain water or any other water (resulting from washing covers or vehicles, or from watering, etc.) falling on the surface of the urbanised territory (except agricultural and green areas) that the manager of the territory wishes or has to collect (using wastewater management systems) and discharge into the environment or into wastewater management systems of other entities (transfer to the wastewater manager). According to the official data, about 63,7 million cubic metres of run-off wastewater were discharged into surface waters in 2012. Only about 10,6 % of the discharged run-off wastewater was treated to reach the established standards, while 89,1 % were discharged untreated. The expanding area of urbanised territories and the growing traffic flow make the collection, treatment and discharge of run-off wastewater increasingly important. In order to deal with these issues, the conditions of run-off wastewater management economy of cities and towns must be assessed and measures must be provided and implemented to develop an economically and technically efficient run-off wastewater management system of cities and towns, which would allow the implementation of environmental provisions applicable to run-off wastewater management and the meeting of needs of the management of run-off wastewater accumulated in cities. Information about the quantities of discharged run-off wastewater is provided on the website of the Environmental Protection Agency http://gamta.lt.
