(e.g. from commercial to private use or vice versa), the submission of a building permit is required.<\/p>\n<p>With the building permit, the development of the property with all necessary media is usually to be proven to the building regulations office.<\/p>\n<p>On the one hand, this affects the sectors of the utility companies, such as electricity, drinking water, gas or district heating and, on the other hand, those of the disposal companies, such as waste water and rainwater.<\/p>\n<p>The rainwater can be disposed of in two different ways, such as connection to the public sewage network or internal infiltration on your own property.<\/p>\n<p>In most areas, the wastewater statutes of the utility companies (municipal utilities or wastewater associations) and the binding land-use planning (for new construction or commercial areas) regulate the type of (rainwater) disposal.<\/p>\n<p>It can happen that the seepage of rainwater on one&#8217;s own property due to unfavorable local site conditions, such as insufficient soil permeability (in clay and loam soils), too high groundwater levels (MHGW) or the stocking of contaminated sites (often in the case of revitalized industrial sites) by statute is excluded from the outset.<\/p>\n<p>But this is not the norm. In most cases, the drainage of the accumulating rainwater is desired on one&#8217;s own property, as this relieves the public sewer system (especially the mixed water sewers) and promotes the formation of new groundwater.<\/p>\n<p>In places where the soil, water and property conditions permit and no binding prohibition has been laid down in the statutes, we strongly recommend our builders to carry out the property-internal infiltration on their own property, there<\/p>\n<\/div><\/section><br \/>\n\n<style type=\"text\/css\" data-created_by=\"avia_inline_auto\"
