It's a dam sewer. Real mess when it backs up.

G-Cans Saitama, Japan. It's the Metropolitan Area Outer Underground Discharge
Tunnel, designed to provide flood control for Tokyo, basically. One of the
largest (if not the largest) underground structures in the world. Excess
rainwater runoff is collected and then pumped out of this reservoir at a rate
that the surrounding rivers can accommodate, preventing flooding. It's an
engineering marvel.

it is basicially a big hold tank, they are building one in chicago and alot of
big cities to handle excess gray water that overwhelms the sewages system. In
times of big rainstorms and lets them hold water then process it rather than
just dump it in a lake or ocean untreated which is what a lot of cities did and
some still do. one of the reason it looks so good is because once they cap and
start it, it is almost impossible to fix it there is one in NY that has lasted
90 years so if they want they can build things right the only reason i know is
before i quit i worked for parsons one of the biggest pipeline contractors in
the world.sorry to chew your ears off
