Two-way pneumatic sewers

Less water, less waste ...

A large proportion of dwellings in the developed world* are equipped with flush WC systems discharging into sewers**.

This means there is an extensive network of piping of minimum 100mm diameter.

Apart from the WC, most domestic wastewater can be safely discharged into street drains.

Under the scheme proposed, WCs would be replaced with "dry" closets that compact waste into biodegradable sealed waxed-cardbord cylindrical cartridges.

These cartridges are then despatched via the new 100mm pneumatic tube network installed in the former sewers to centralised facilites for processing and disposal.

The same tubed system can then also be utilised for sending and receiving goods which can withstand the g-forces involved.

Disruption to existing infrastructure is minimised, and much water is conserved.

** not france. Or Belgium, either (apparently). Or maybe the stench just drifts Northward on the breeze ..

       Put it in the post, addressed to your favourite political recipient; then you don't need tubes at all.

       8th: let me acquaint you with Igordo Kang and his marvelous but devastating vegan korean burritos. We will see if the waxed cardboard is doughty enough to receive the intestinal fury they provoke. And if so, or partially so, we will see how the pineapples taste after receiving them thru the same tube that just send out the used burrito.

       I'm gonna guess that, for awhile, people will either be walking buckets over to hydroponics, or utilizing the "linked sausages" method detailed in another post.
