Wastewater tunnels south and north of Sjölunda wastewater treatment plant
One wastewater tunnel under Malmö and one wastewater tunnel connecting the municipalities of Burlöv, Lomma, and Lund addresses the challenges of population growth and an obsolete wastewater system, and enables protection of our local water environment. MAXIMA allows more people to live and work in the region.

If a wastewater treatment system is unable to handle the volumes of water that can occur during, for example, heavy rain, the water must be let through anyway – so-called overflow discharge. If a pumping station or some other part of the facility overflows, important equipment risks being destroyed, which can cause major problems and costs. Overflow means that untreated wastewater is discharged into nearby waterways, such as Malmö's canals or the Öresund.

Tunnels are an increasingly common solution
In densely populated communities in regions with strong population growth, wastewater tunnels are becoming increasingly common. In the Nordic countries, wastewater tunnels exist or are planned in cities such as Copenhagen, Stockholm, Gothenburg, Oslo and Helsinki. In Copenhagen, tunnels are drilled using the same technology planned for MAXIMA and in comparable geological conditions.
