Construction of a sewage system in Gdańsk-Jasień

Project: 

Construction of a sanitary sewage system in Gdańsk - Jasień, Kartuska street

Modular pipes used: PP 180x10.2x600 / 700

Gravity drop: i = 1.5%

Installation length: 16.5 m

Sanitary sewerage construction, typical for the technology of precise horizontal drilling MIDO. The implementation required high precision of the set gravitational drop. The installation is located under a busy street, the exclusion of which would result in significant traffic difficulties, especially during rush hours. Using our Gravity Drilling technology, communication difficulties were limited to the partial occupation of one lane of traffic adjacent to the DN 1200 starting well.
