It's done. Mostly.

Two days, and somewhere about $4500 later, we have a new sewer line.  The final tally looks like this:

New sewer line from the house almost to the street.  The city gets real funny about working too close to the main, so once you reach the easement (that area between the telephone poles and the street), you're done: you tie into whatever you can find and leave it at that.

What came out of the house was 6".  What tied into the main was 6".  So what they put in was 6".  In very real terms, we could service the sewer needs of a twenty unit motel, or flush a full grown toy poodle.  Hopefully, neither will ever be necessary.  (To put this in perspective, the average house in America today only has a 4" line.  I'll let you do the math, but the difference in performance is more than you might think.)

The trench was 8'-3" deep at the lowest part.  That's really damn deep, in case you were wondering.   

When I said it was done mostly, what I meant is that sewer and water lines are hooked up and functioning.  That's all done.  There's still 12 linear feet of trench to be filled in, but it was 7:00 and the guys were tired.  When they decided to stop for the night, we didn't argue.

So, it was expensive; the front lawn is destroyed: a backhoe does damage just by being present.  It's messy as hell out there.  BUT, short of some geologic event, we will never have problems with the sewer again.  

I'm sure I'll have more to say about it, but not now.  It's shower and bed time.

p.s.  Two things you always remember as a plumber.  1: shit runs downhill.  2.  Don't chew your fingernails.

For the math-challenged...

6" / 4" = 1.5. The cross-sectional area increases with the square of the diameter, so a 6" pipe has cross-sectional area (3 / 2) **2 = 9/4 = 2.25 that of a 4" pipe.

Same reason that a small increase in monitor diagonal measurement makes more of a difference than you'd initially think.

*chuckle*

I was wondering if anyone would actually post something like that.

10 points for the answer, and thank you for showing your work.
