Traditional plumbing systems send all wastewater — toilet waste, sink water, and food scraps — into the same sewage network. Once mixed, separating and processing these materials becomes complex and inefficient.
Swedish engineers approached the problem differently: separate the waste streams at the source.
The result is a system with three independent pipelines, each optimized for a specific type of waste.
1. Vacuum Toilets: Efficient Waste Transport
The first pipe connects to vacuum toilets, a technology commonly used in airplanes and high-speed trains.
Instead of flushing several liters of water per use like conventional toilets, vacuum toilets rely on air pressure and suction to move waste through the system. This dramatically reduces water consumption while still ensuring efficient transport of waste.
Because the waste is more concentrated and not diluted with large amounts of water, it can be processed more efficiently in treatment facilities.
