In the center of Kraków, the City of Polish Kings, in a small street named after Ludwik Zamenhof, in May 2021, INVEST-LEX company rehabilitated an egg-shaped, 600/900 mm, combined sewer system.

The above Contractor was selected by Kraków water system company, Wodociągi Miasta Krakowa S.A., and during the installation representatives of POliner and BLEJKAN companies provided technical support.

A POliner Glass UV liner (previously called Mazur Liner UV) was used. The installed liner was 63 m long, had a replacement diameter of 757 mm, and a thickness of 8 mm.

The whole process was carried out smoothly, quickly, and efficiently, thanks to the knowledge and experience of the Contractor’s team and the egg-shaped liner that fit the sewer perfectly, all combined with the provided technical assistance. The entire process started and was completed within one day.

We appreciate the trust vested in our products and expertise, and look forward to more business in the future.
