Osireion Water Contains Unique Filtering System. Water is mixture of Old Nile Water (pre-1970), Recent Nile Water (post-1970), and paleowater from deeper aquifers Osireion water has lowest Total Dissolved Solids and Electrical Conductivity among sampled waters Water contains fewer minerals (calcium, sodium, magnesium, bicarbonates, chlorine) than nearby wells

Researchers discovered Osireion's water has the lowest mineral content and bacteria levels of any sampled well in the area, despite the site being open to tourists. The water is a mix of Old Nile, Recent Nile, and deep paleowater. The hypothesis: Osireion functioned as both a cistern reservoir and natural water treatment facility.

Key Facts

  • Water is mixture of Old Nile Water (pre-1970), Recent Nile Water (post-1970), and paleowater from deeper aquifers
  • Osireion water has lowest Total Dissolved Solids and Electrical Conductivity among sampled waters
  • Water contains fewer minerals (calcium, sodium, magnesium, bicarbonates, chlorine) than nearby wells
  • Osireion water has much lower total coliform and fecal coliform bacteria than surrounding wells despite being open to tourists
  • Seismic scans show central island extends 15 meters down and contains voids or irregularities
  • Structure cannot be fully dewatered - water gushes in from bottom at 500 gallons per minute
  • Hypothesis suggests Osireion functions as combined cistern reservoir and water treatment facility
