This is a collection of frequently answered questions about the planned MAXIMA wastewater treatment system.
A regional solution for several municipalities
What is MAXIMA?
The MAXIMA wastewater treatment system is VA SYD’s investment in a new regional infrastructure for sustainable wastewater treatment in the member municipalities of Burlöv, Lomma, Malmö and Svedala, which VA SYD is also offering the opportunity to become a member. This will be one of the biggest infrastructure investments in the region in the near future and is essential if the growth region of southwest Skåne is to be able to continue to grow. With a shared solution, VA SYD meets the need for expansion and modernisation of the wastewater treatment system in the municipalities, protects local aquatic environments and allows cities to grow.
What does MAXIMA include?
MAXIMA currently includes a robust new Sjölunda wastewater treatment plant on the outskirts of Malmö next to the Öresund, outlet pipes into the Öresund, a large new pumping station at the Sjölunda wastewater treatment plant, a wastewater tunnel beneath the centre of Malmö, and transfer pipes and the necessary pumping stations to connect the municipalities of Burlöv, Lomma and Svedala to Sjölunda wastewater treatment plant.
How are the municipalities and treatment plants in southwest Skåne affected?
It is more economical to expand in one place instead of several local treatment plants. Sjölunda wastewater treatment plant is a more suitable location in terms of both impact on the aquatic environment and urban development.
When we expand the Sjölunda wastewater treatment plant in Malmö, we are building and modernising for the region. This may mean that the community no longer needs several local treatment plants, and the sites can be used for other purposes after decommissioning. It will be more economical for each municipality not to need to expand and modernise their local wastewater treatment plant.
Is it not better to invest in new property-based wastewater technologies?
There is no contradiction between planning to develop our main regional wastewater treatment system and new wastewater technologies. However, it is important to realise that the water supply and wastewater infrastructure we have today, and on which we are completely dependent, has been built up over more than a century. It needs to be managed, renewed and adapted to new requirements.
Converting it to something else, such as property-based solutions, would take a very long time with unpredictable costs, as the technical solutions do not exist on a large scale today. Regardless of how things develop, we need a sustainable, robust water supply and wastewater system that stands the test of time.
Has a decision been made to build a new regional wastewater treatment system?
Work is now under way to establish an implementation agreement with the municipalities concerned. This is necessary to allow VA SYD to continue the planning and implementation of MAXIMA. You can read more about the decision-making process here.
What is the alternative to a major new regional wastewater treatment plant in Malmö?
If invited municipalities reject a regional solution, they will need to expand and modernise their local wastewater treatment plants. This will be necessary to cope with strong population growth and stricter environmental legislation.
Why does VA SYD favour a regional solution over local expansion?
The idea that regional expansion is better than several local expansions is supported by our collective expertise at VA SYD, studies, and reports and external analyses from the Swedish trade association Svenskt Vatten. You find this material under Information material and Reports and studies.
Svenskt Vatten points out that a large organisation and cooperation are required to meet the re-quirements for costs, staff, expertise and advanced treatment technology. You can read more about this in Svenskt Vatten’s 2020 investment report.
