Our new Ecoliance e.V. member "SWIS"

SWIS GmbH ( Sustainable Water Infrastructure Solutions) is a start-up company from Kaiserslautern that offers software solutions for urban water management. The first software product is a tool for the automated planning of sewer networks called ZIGGURAT.

The team behind ZIGGURAT, an innovative algorithm that takes the planning of sewer networks for wastewater, stormwater or combined sewer to a completely new level, are former employees of the Department of Urban Water Management at the Rhineland-Palatinate Technical University Kaiserslautern-Landau.

The future of sewer network planning is here:

ZIGGURAT enables automated, efficient and forward-looking planning of sewer networks, taking blue-green infrastructures into account. From layout and (de)centralisation to sewer diameters, gradients, installation depths, pumping and storage facilities - our solution takes all these variables into account to deliver tailored and optimal results.


  • Efficiency: Automating the planning process saves you time and resources.
  • Versatility: Whether wastewater, stormwater or combined sewerage - ZIGGURAT adapts to your requirements.
  • Optimisation: The algorithm takes a large number of variables into account to achieve the best possible result.
  • Sustainability: Integration of blue-green infrastructures for environmentally friendly urban development.

The smart approach:

ZIGGURAT is based on current findings from our own research in the fields of urban drainage and hydroinformatics. The algorithm requires only a few input data to start planning and provides you with comprehensive results in the shortest possible time.

Take the first step into the future:

Please approach our new Ecoliance member openly and give him the opportunity to introduce ZIGGURAT personally and explain the advantages for your problems. Efficient, automated and future-oriented sewer network planning opens up new horizons and optimises your projects.

We keep our fingers crossed for the SWIS team and will be happy to support them.
