The tram route to Mistrzejowice is much more than just laying tracks between the existing terminus in Mistrzejowice and the intersection of Mogilska and Jana Pawła II Streets. It also involves the redevelopment of as much as 335 kilometers of existing infrastructure.
Redeveloping underground infrastructure in a large city is a complex process that requires efforts by many specialists. In the northern part of Kraków, it includes upgrades to the water, heating, sewage, gas, electricity and teletechnical networks as well as the redevelopment of the Sudół Dominikański watercourse. Their total length is as much as 335 kilometers. The redevelopment is necessary to provide residents with access to safe and sustainable infrastructure.
Types of networks to be rebuilt:
Water supply networks – 5.23 kilometers,
District heating networks – 1.02 kilometers,
Sewerage networks – 9.41 kilometers,
Gas networks – 2.92 kilometers,
Sudół Dominikański – 0.39 kilometers. It is an underground river which we described here,
Electricity networks – 45.54 kilometers,
Telecommunications networks – 270.56 kilometers.
Redeveloping underground infrastructure is a complex process that requires precise planning and coordination of activities. The work is carried out with the highest safety standards and takes place in stages. Once a new element is completed (for example, a trunk pipe made of ductile iron), the old infrastructure is repiped and then dismantled. Currently, the focus is on creating new underground infrastructure. The repiping is planned for the off-season.
Underground networks are mainly placed under sidewalks, bike paths and in green belts. This allows easy access to installations during repair or maintenance work. In the case of repairs, this does not require disturbing the road surface, which minimizes disruption to traffic.
