==A primary Sanitation Infrastructure in Rapture==

System :
Who created those OPEN SEWERS we saw ??? ( There ARE things called 'pipes', even in 1946. These open ways are usually used for Street Drains/water-runoff. )
Water Reclamation ??? Except Seawater Purification likely would be cheaper/simpler/more-efficient ( 'use for agricultural' not probable with most farms being hydroponic ). Cleaning up water is alot of work and requires chemicals not sourceable in Rapture.
We saw some kind of open drainage in McDonagh's Tavern (storage areas) but they then connected to some watery decorative motif near the entrance. That needs to be fixed up a bit ( stagnant water and sewer smells is not condusive to pleasing customers ).

All Bad Things of Rapture Flow Out of the City -  Rapture Sewage and Party Rental Ltd :
A take-off on that underwater sign you see when first coming to Rapture in the Bathysphere.
Rapture would recycle alot of stuff ( valuable because otherwise it has to be brought expensively into Rapture ).  Sounds like a good basic 'dole' job for newly cured ex-Splicers.
Recycling water, various effluvium for 'fertilizer'.  Toxic waste from industries usually cost too much to process.

Sewer Gas Suppression :
Methane gas is given off by decaying organic materials, a substantial amount would be generated by Rapture's sewer system. Since Rapture is a closed system the gas cannot be vented as it is in a surface city. To prevent methane accumulation and potential methane explosions, Rapture was designed with a system to prevent this problem.
* Some Sewage is pumped directly into the Ocean at the earliest possibility ( another function of those large Pumping Stations ).
* Other 'piped' Effluvium is promptly sent to a sewage plant ( located on Mt Ryan ) for processing and fertilizer extraction ( needed for the many Farms ).
* The sewage pumped into the Ocean accounts for the abundant Sea Life seen 'Outside' on the seabed in these dark depths and the constant presence of fish, because of the extra nutrients.
* Byproducts of the sewage plant are used to improve the yield of the Sea Weed farms - most also located on the shallow depths of Mt Ryan ( Rapture sewage being sprayed upon the crops would vastly increase the yield ).

None of the Toilets in Rapture Had TP Dispensers ??? :
Toilet Paper.
Rather un-hygienic, though this might be a case of 'bring your own', like in non-US parts of the world, though you might have expected an overpriced Vending Machine then to take care of people who forgot.   But then, there are none ( toilet paper rollers ) in the ritzy private apartments either ( does this indicate some amazing technical innovation ?? Or a 'Plasmid' to handle this issue ?? ... Heh. )
Possibly its some new 'high tech' toilet technology ( early enough in the City's history to have them all TP-less even in Fontaine's flophouses ??? ) ?   All will be explained in the MMORPG (one way or another).
McClendon Auto Toilets - only with test units like in Fort Frolic - and the project was then stalled by the 'civil war' ??

There was a BioShock Concept NPC type called 'Survivors', which the Player was to have some dealings with - Like getting supplies from ( before the Vending Machines idea was selected for that operation ).
This picture is of some Real World 'sewer inspectors' who would go thru the underground sewers in cities looking for problems which might require maintenance. ( Prudent measures called for proactive maintenance, unlike so much of the Parasite-laden Surface World, with its 'Sit on their hands' clock-atching government workers. )
Perhaps the Large Hot Water Pipes which run from Hephaestus ( a major part of Rapture's Heating system ) would have teams like these to do periodic inspections and repairs.
