Surveying drinking water, waste water, electrical cable

In Lower Saxony, TRIGIS designed route options for a medium voltage line in combination with a drinking water pressure line and a waste water pressure line. The line had to go through the Harz National Park and cross a main road twice.

Method

TRIGIS designed a 4 kilometer-long medium voltage cable in combination with a drinking water and waste water line for compression of the telecom network, new construction of a medium voltage cable as replacement for the removal of a medium voltage overhead line, and a connection of city districts to a central treatment plant.

In the process, a main road was crossed twice. TRIGIS surveyed the cables, designed the main road crossing and took care of the approval planning process, in particular the obtaining of all necessary approvals.

Soon after the approvals came for the comparison of routing variants and then the construction permit.
