We went by the Southeast sewage treatment plant and picked up six free
sacks of compost. They loaded them into the car for us, gave us their
DVD "The Sewers of San Francisco", and a free mouse pad!

They have real tours, too; we'll have to schedule one. I've done the
Sewers of Paris tour, so it will be interesting to compare.

Why in the world would you subject yourself to a tour of a SEWER?

I've always thought it interesting that, under every city, there's
another set of structures we never see: foundations, caissons,
transformer vaults, pumping stations, subway tunnels, water and gas
distribution, wire and fiberoptics communications, and one or often
two separate wastewater systems, all sorts of things. I'm an
electrical engineer, but civil engineering really impresses me.

OK, some people don't think of stuff like this, and would rather watch
reruns of "Gunsmoke" without thinking about the cable distribution
system underneath the streets.

Underneath parts of Edinburgh, there are complete streets which have
been built over and are now open to tourists.

This is true in some U.S. cities as well, such as Seattle that was re-built at
least once (I believe it's actually been rebuilt several times -- fire did it
in once too) after severe flooding in the city's early days. The original
"street level" is something like 10' below the current "street level."

It is really cool to see all these old underground "ghost" towns.

Back at the Univ. of Minn., there was a legend that there were "steam
tunnels", and supposedly, you could get to them through the dorm basement,
and follow them to the basements of the girls' dorms, and go on panty
raids and stuff.

I never actually saw one, however. )-; (or a panty raid! D-; )

Thanks!

Why in the world would you pass up such an interesting tour unless
you're the type that sits around watching Oprah for all your
informational needs. Large industrial/civil processes are quite
interesting.

Don't get me wrong,I find it interesting too...I'm fascinated by the
local water system,it comes to town in giant pipes,and is collected in
various tanks,some *in* a big hill behind my house..

Sewers and lift pumps,etc. are interesting too...

But not interesting enough to crawl into them....EWW!

When I went skydiving in Baldwin, WI fifteen or twenty years ago, the
drop zone had a big huge sewage treatment thing next to it, which
they called the "turd swirl". They recommended that if your main
chute and backup both malfunction, to aim for it, because it would
be softer than the ground. =:-O

Interestingly, there was no noticeable odor from it.

Yep. When I was scouting out universities while I was still in high
school there was a demonstration at the University of Cincinnati of a
sewer mechanism to handle low flow neighborhoods.... a cistern filled
up with sewage and water until it reached a certain critical level,
then flushed itself... no moving parts.

How did it retain and release the sewage with no moving parts?

Just like a toilet does when you exceed a certain water level in the
bowl.

This is a common technique used in some septic tanks to give the drainage
field a break. The tank is broken into two chambers. The first chamber
holds the nasty stuff, and overflows into the second chamber. The second
chamber has a pipe that comes up from its bottom, and performs an upside
down "U" bend that goes back to the bottom (inlet). When the tank fills
enough to make the water fall over the top of the "U" bend, it forms a
siphon which draws all of the water out of the chamber.

In the case of a septic tank, the pipe that forms the "U" bend has to be
sized small enough that a toilet flush will cause it to fill completely
and start the siphon. This is not a problem, because the second chamber
has nothing but water in it. For a municipal sewage system, the bend would
have to be sized based on the usual usual flow surges that occur in the
sewer lines.

Cool!

In the '80s, a student of mine got a job working there. She was doing
all sorts of interesting instrumentation projects. I visited her at
work once, and was very impressed.

Sounds like, in the time since then and now, they've built themselves
a PR department. DVD? That's a surprise!

Be careful how you use that compost. I don't know how it is now, but
there used to be a problem with heavy metal contamination of that
stuff.

Did they call it "Milorganite?" My Dad used to buy that stuff for the
garden.
