From demolition to new installation at Råg, Havre and Vetegatan in Piteå

The project involves the rehabilitation and upgrading of existing water and sewerage systems (WSS). The work includes demolition of old water pipes, laying of new water pipes.

The first phase of the project consisted of the demolition and removal of the existing water and sewerage systems. The demolition work requires careful planning to prevent future leaks and system failures. After the demolition, the installation of new water and sewerage pipes will start. These pipes are designed to meet modern standards and requirements for durability and efficiency. Careful positioning and sealing of the pipes to ensure they are properly connected and free from potential leakage points. We use high-quality materials that guarantee long service life and resistance to corrosion and other types of damage.

Methods we used in this implementation:

Relining
Relining is a method we use where new pipes are inserted into the old pipes without having to dig up the entire system. This method is both cost-effective and time-saving, and reduces disruption to surrounding infrastructure and communities. The process involves both inspection and insertion of new pipe.

Directional drilling
Directional drilling is a technique we use to install new pipelines underground without having to open up large shafts. It is particularly useful in densely populated areas or where traditional digging would cause significant disruption.

Three-wire shaft in Street
Finally, the project involved three-pipe shafts, which meant that three separate pipes (for water, sewerage and possibly stormwater) are installed in parallel in the same shaft.
