Wastewater Regulation<\/h1>\n\n\n\n
\"\"<\/figure>\n\n\n\n

The new wastewater regulation brings changes to wastewater treatment in sparsely populated areas. The new law concerning wastewater treatment came into force in Finland in 2017, and the deadline for making changes to wastewater systems based on it was in October 2019.<\/p>\n\n\n\t\t<\/div>\n\t<\/div>\n<\/section>\n\n\n

Wastewater Regulation – What Does It Mean and Who Does It Affect?<\/h2>\n\n\n\n
\"\"<\/figure>\n\n\n\n

In summary, the purpose of the decree clarifying the law is as follows: if your property located in a sparsely populated area meets the required conditions, you must arrange compliant treatment for household wastewater, for example with a wastewater treatment system<\/a>.<\/p>\n\n\n\t<\/div>\n<\/section>\n\n\n

Proper Wastewater Treatment Improves the Cleanliness of Nearby Water Bodies<\/h2>\n\n\n\n
\"\"<\/figure>\n\n\n\n

The long-prepared law is based on the idea of efficient, safe and environmentally sound wastewater treatment. If wastewater were not treated properly, it could end up polluting nearby water bodies and, for example, groundwater. Good planning of wastewater treatment therefore protects the nature around us.<\/p>\n\n\n\n

Careless wastewater treatment can lead, for example, to contaminated well water and eutrophication of swimming beaches. The aim of wastewater treatment is therefore to keep your own water and the waters around you safely clean and usable.<\/p>\n\n\n<\/div>\n\n\n\n

Who Does the New Wastewater Regulation Affect?<\/summary>\n\n

The new wastewater regulation applies to properties in sparsely populated areas that use mains water and meet the following conditions.<\/p>\n\n\n\n

The wastewater system must be renewed if your property is located no more than 100 meters from water bodies or the sea, or in a groundwater area.<\/strong> The building can be, for example, a residential house, summer cottage, lakeside sauna, agricultural building, or a holiday cottage or camp center used for business purposes.<\/p>\n\n\n\n

In some cases, the regulation also applies to other properties located outside shoreline and groundwater areas in connection with major renovations. If, for example, you are installing a flush toilet or doing other plumbing work requiring a building permit, the wastewater system must be renewed at the same time.<\/p>\n\n\n\n

According to the law, action must be taken by October 31, 2019, if the conditions are met.<\/p>\n\n\n<\/details>\n\n\n\n

When Does the Wastewater Regulation Not Need to Be Considered?<\/summary>\n\n

Renewing the wastewater system does not affect all residents of sparsely populated areas. The law specifies the conditions under which you do not need to make changes to your wastewater treatment.<\/p>\n\n\n\n

You do not need to renew your wastewater system if<\/strong><\/p>\n\n\n\n
