Transparent procedure: Communication about its own ERDWÄRME – BREISGAU project is very important to the badenova subsidiary. Therefore, citizens are invited to find out more about the hiking convoy and the special vehicles as well as the project itself. The performance will take place on Saturday, January 8th in Breisach am Rhein (Bahnhofstrasse 35, 10 a.m. to 1 p.m.). When the event is held, the current regulations of the Corona Protection Ordinance apply. It is a 2G + event, and a mask is required. The implementation on Saturday depends on the current pandemic situation.
(If this is not possible, badenova will inform you via press information and at www.badenovawaermeplus.de/geothermie.)
Offer for the media: To inform the local media, badenova will offer a separate press event around the start of the measurements.
In the run-up to the 3D seismic survey, badenovaWÄRMEPLUS obtained permission to enter the property from the property owners and tenants concerned. The measurement area includes Breisach am Rhein, Merdingen, Freiburg-Munzingen, Schallstadt, Ehrenkirchen, Bad Krozingen and Hartheim. There the geological structures are examined for naturally hot thermal water resources. Interventions in the subsurface are not associated with 3D seismics.
How 3D seismics work: At the start of the measurement, the measurement points are marked in the relevant area. Then geophones are put into the earth. Geophones are about six inches tall measuring sticks that work similarly to microphones. Measurements are made wirelessly. A traveling convoy, consisting of three impulse vehicles, drives through the measurement area. While the vehicles are in use, they are accompanied by traffic safety vehicles. They stop every 40 meters and generate pulses or sound waves underground. The geophones pick up the impulses reflected from the various layers of rock in the subsurface. With this measurement, experts can create a concrete and very detailed picture of the geological structures down to a depth of around 3,000 m. The 3D seismic measurements should be finished at the beginning of March 2022.
What are the effects of the measurements?
The convoy can cause short-term traffic disruptions as the following traffic has to wait briefly (comparable to garbage collection). Operating noises can be heard close to the measurements, similar to what occurs in small construction projects. The vibrations caused by the impulse vehicles can be felt in a narrower radius and correspond roughly to the vibrations when a tram drives past. These low-intensity seismic waves are barely perceptible to humans and animals and are harmless.
Safety is a top priority: Additional accompanying measurements ensure that all standards and safety regulations for buildings are complied with. Measurements are made exclusively on the surface of the earth. “Like any construction vehicle, the impulse vehicles can easily sink in or create hollows on unpaved roads. If you discover such or other damage or if you have any further questions, please contact us. We take care of it unbureaucratically ”, says Simon Laub, project manager of badenovaWÄRMEPLUS.
