However, the installation of planted filters remains a greater investment than that of a conventional solution (For 5 PE: approximately 10,000 € for planted filters, versus 7,000 € for an all-water septic system). The system becomes profitable at around 15 years, as it demands neither management by a professional workforce, tank drainage (there is no tank), nor energy (apart from cases requiring a sewage pump station for powering the filters, but this costs only a few euros per year where necessary).
