Decent paper. Consistent with Metcalf & Eddy.
IMHO, he disinfection of the filovirus will focus on the 70nm x 760nm filtration or its chemical destruction/incineration.
Source control is simplest to protect existing infrastructure, but the most costly, ...but would have to rely on economies of scale for efficient implementation.
Probably need a water trap or plumbing fixture component able to filter/disinfect the wastewater stream.
Such a system would be very costly to implement, but would make wastewater treatment at the centralized source much more efficient,...perhaps too efficient, i.e. not enough food for the biologicals to feed.
It might be better addressed as an Ezekiel 7/8 problem and let God handle it.
