Without a proper medical center and without professional sickness screening, some individuals could inadvertently bring with them all sorts of infections and diseases. This could harm hundreds.
Such an incident could mark the end of an entire community as the shelter was intended to house all residents around. Instead of being a shelter of safety, it would turn into a mass grave.
A rusty old door stood between the real world and what would soon be discovered as an isolated shelter from a modern threat against humanity, as seen through Bruce's eyes.
This door was the only part of the Ark visible to the outside world. Behind that door stood a power generator and from there on, the underground labyrinth began.
The Living Area
Moor than 14 feet separated the ground level from the actual habitat. The living area of this place was hidden deep below. So, you might have thought that getting into the shelter was the main obstacle, however, once in, bigger issues were awaiting.
The living area down below was so compressed and lacking natural airflow, that if one person carried a virus or some sort of illness, the outcome would have been chaotic.
Bruce, as always, thought a few steps ahead and built a decontamination chamber at the entrance to the shelter, right after the heavy steel door. This was to reduce any risk of contamination and of spreading of disease.
Bruce built this chamber to perfection. It had a double sink made of stainless steel, a shower for adults, and a bathtub for children and disabled people. It even had a food decontamination section! If Bruce was going to do something, he was going to do it properly.
More Was Needed
The chamber at the entrance to his underground world was not the only professionalized room. Those entering the enigma would need more than a sterilization unit to survive. Electricity, fresh running water, and much more were essential. Bruce thought of all this way in advance and an entire plumbing system was planned and installed underneath the living areas.
It ran along the entire premises and ended in a septic tank. The bunker had access to potable water from a nearby well, making the stay as convenient as possible.
