One of our german customers - Frank GmbH - produces large diameter pipes (up to DN/ID 3500) for waste water collection points in the course of the large construction site Stuttgart 21.
In the videos you can see in which dimensions pipes can be used with Krah Pipe Production Technology.

Manila, capital of the Philippines, has around 1,8 Mio inhabitants and is situated in the agglomeration “Metro Manila” with a total of 12,9 Mio citizens. The immense population pressure since the middle of the 20th century caused an uncontrolled expansion of the city Manila and the surrounding conurbation.

The planning and construction of the installations of sewage discharge and treatment systems as well as storm water distribution could not keep up with this growth. Thus, drainage systems yes do exist, but do not meet in any way to the objectives of integral urban drainage systems. Especially the inadequate hydraulic dimensioning of the distribution pipelines, which are mostly done in the diameter of DN/ID 900 mm, regularly lead to overload flooding in a lot of districts of Manila.

The hydraulic failure of the systems is even intensified by the need of relining and repair, wrongly constructed manholes, false installation of the pipelines as well as root infiltration and blockings. On basis of the applied regulations of the German association for water management, waste water and waste (Deutsche Vereinigung für Wasserwirtschaft, Abwasser und Abfall e. V. (DWA)) and DIN norms possibilities for a safe discharge of waste water as well as the protection against flooding shall be presented.The current situation in Manila is difficult: Due to the demographic development of the last decades in the agglomeration of „Metro Manila“ and the city of Manila, the populated areas have multiplied. This expansion of populated areas happened without a sustainable planning of a secure waste water discharge and storm water distribution system. Thus, consequently, the protection of humans and goods against flooding in the residential areas and a proper discharge of waste water were not ensured. The sewage system based on a sewage and storm mixed system was extended with the growing settlement but without adapting the existing system to the hydraulic additional load. Natural discharge ways and retention areas were overbuilt without creating sufficient countervailing measures. The still existing open water channels were often limited and restricted by dense constructions. Bridges without sufficient freeboard, encroaching buildings of all kinds as well as deposit of rubbish is existent, which reduces the drainage system width considerably.

Leaders of Ukrainian market of construction and installation of pipelines are ready to work on international level

On November 2016 in Lviv, Ukraine, there was a solemn ceremony of opening a new tramline connecting residential district Sykhiv with central part of the city. Only few people attending the ceremony knew that it was preceded by another event, not less important for the city’s life. It was replacement of old 520-meters underground non-pressure sewage collector located directly under the future tramline track. Replacement of the old sewage collector on the Stusa Street was the biggest infrastructural project implemented in the period of Ukraine’s independence over last 26 years.

Worn-out condition of the old collector could have caused damage of the road bed above it. That’s why Lviv City Council and Lvivvodocanal organization decided to urgently replace the old collector with a new one. This difficult task was assigned to INSTALPLAST HV company and its subdivision INSTALBUD which performs works on construction and installation of internal and external pipelines, natural gas pipelines and sewage networks. Replacement works were done according to the project designed by German specialists. The works started in June 2015 and were accomplished in July 2016. Pipes PE of DN 1600 mm SN10 were used for a new collector. These pipes were manufactured by INSTALPLAST on its own equipment purchased from leading German company KRAH.
