There is no standard depth and certainly no standard length. The length is from your building to the city sewer, varies by lot size. depth is generally 4' but that varies based on your climate. Frost depth plays into the dig.
You are obviously reading fom a test or study guide. What kind of test are you taking, home inspection??
what is the standard depth of a residential sewer line? what is the standard distance of sewer pipe to the house?
This question's like asking, " How high is up?". There is no "standard" to either the depth or length of a sewer line. As Bob pointed out, It varies by area. Now! Please tell, us why you're asking and where you got the question from? Regards, tom
Depth largely depends on amount of "fall" available on a gravity based system. If the house being served is barely about the sewer main line, you obviously can't go too deep, as to have sufficient flow. Are you replacing an old line? Installing a new one? Or just taking a test?

Not quite true! Your depth will depend pon the frost line in the area. The city and county installations must all fall below the frost line so the house sewer line would naturally do the same. Regards, tom

Well, it is quite true down here, where the frost line is no issue. I was speaking on the principle of gravity feeds also. Peace.
I was speaking on the principle of gravity feeds .
All house sewers are "gravity fed". In my area we slope them at 1/4 or 1/.8" to the foot until we reach the street where we 45 down to pick up the citys main raiser.
