REMEMBER : Water uphill is undrinkable. It is Nile overflow.
The Osireion can almost be reactived. Just put back roof on it, and on mortuary temple, and divert water from above, into mortuary temple, let water recess, use resulting vacuum to pull freshwater into Osireion. TODAY !
Osireion is a giant Shop-Vac with 15 hoses/straws,
like Khafre valley temple is a giant Shop-Vac with 2 straws/hoses.
Osireion (valley temple) had an airtight/hermetic implosion-resistant rock roof, just like Khafre valley temple,and just like the mortuary temples.
Mortuary temple was a vacuum source caused by recessing water. This vacuum was renewed daily, which required daily refill of mortuary temple, using Nile overflow from 900 m away, slightly above.
The vacuum was used to pump fresh groundwater into the valley temple.
