Land drainage and sewer connection
Proper disposal of dirt and rainwater is a matter of course for many. However, responsibility is not limited to public wastewater disposal. Every single landowner is required here.
The wastewater of a building is fed via the so-called land drainage system (GEA) to the public sewer. The property owner is responsible for the construction and maintenance of this facility. The accumulating rainwater is to be seeped into the new development - as far as technically possible - on the property.
Checking the canal house connection
The network of public canals in the city of Landshut must be regularly maintained and repaired in the event of damage like any other building. The municipal utilities regularly check the main and connecting canals in the public road area to see if they are tight.
Property owners must also have their own drainage pipes in the ground regularly checked for damage, for example via a camera inspection. Irrespective of the stipulated deadlines in the drainage statute of the city of Landshut, you should ensure in your own interest the lasting functioning of your drainage system. As with the car or the heater, it usually only gets really expensive if damage is detected too late or an emergency situation has occurred.
And: Functional lines serve both environmental and water protection as well as the value preservation of your property.

At the latest, if Stadtwerke Landshut checks the public sewer main lines and property connections as part of the self-monitoring, you must expect that the Stadtwerke demand proof of the absence of defects in your property drainage system.
Our tip: Ask Stadtwerke Landshut if the municipal sewers in the connection area will be checked in the near future or if sewer or road construction measures are planned. You may receive a favorable offer for your own commission from the companies commissioned by Stadtwerke, which are already working on site anyway. You will find more tips in our guide to checking the canal house connection.
Frequently Asked Questions (FAQ) & Info
Protection against backwater
Basements are threatened with a particular unwelcome form of moisture against which it has to be secured: a backwater from the public sewer system. This can happen, for example, during heavy rain or when the public sewer system becomes blocked. In the event of backwater, for example, wastewater can penetrate into basements via wash basins, washing machines, floor drains or toilets and cause damage.
Owners can protect themselves through a backwater protection. The drainage statute of the city of Landshut provides homeowners with such a safeguard in § 9 (6): "Against the backwater of the wastewater from the drainage device, each subscriber has to protect itself. Unless otherwise specified by the city for the individual case, the road level at the junction shall be assumed to be the backflow level. "
For example, a wastewater lifting plant can help. Lifting systems collect the wastewater that accumulates under the backflow level in appropriate storage containers and then pump it via the backflow loop into the sewer system. Easier backflow stops interrupt the flow in backflow-prone sewers through valves, gate valves or pinch valves.
Experts, who should always be consulted for the installation of such fuses, advise mostly to sewage lifting equipment. Because only with her the house drainage in the basement rooms remains fully operational. The backup against backwater is only effective if they are regularly maintained. Homeowners have to expect a backwater, even if it has not come to that. Sanitary installers are the right contact person and are happy to clarify.
Further information on this subject can be found in the flyer "Protection against backwater".
Introduction of groundwater
For construction projects in the groundwater area or for pumping tests on private land, it may be necessary to build up or discharge discharged groundwater into the public sewer system if there is no possibility of seepage (eg no suitable infiltration areas or contaminated groundwater prevails) or other diversion (eg, inflow into a body of water).
A permit for the discharge of groundwater into the public sewage system is to be applied for from Stadtwerke Landshut, sewage sector. To do this, please submit a plan extract with a description of the location of the planned construction water system or the well boreholes and indicate the expected discharge volume and the planned pump period for assessment.
