Recently purchased a large parcel of land in northern, rural California. A few decent sized towns near, so contractors and equipment are reasonably close (quincy area). Soil conditions seem amenable for digging (higher elevation, pine/doug fir, loamy, reddish soil... but some rocks likely).

Need to dig a 1000 foot long utility trench to bring water, power and telco to home site. All can be put in same trench, water at bottom... 4 feet deep.

Need an estimate of trench cost, plus a return trip to backfill after inspections. Do not include pipe costs, wire, etc.

Soil does not need to be compacted.

Thanks!

It's not really meaningful to ask for quotes on a world wide site such as this one.
Call 2 or 3 locally and they will be happy to look at your land.
Where I live (northeast) a backhoe is usually $125 hour for one man and $25 for a helper if needed.
They won't quote a fixed price because of rocks.
1000' down 4' sounds like it would take all of one day, if big boulders aren't a problem.

Only way to get cost concepts is to get quotes from local contractors.

All can be put in same trench,

I really really doubt that. Better check and recheck. And if you can do it, I wouldn't do it.

Depending on size of rocks anticipated check out using a trenching machine.

Check into going to home Depot or any equipment rental place and find out the price of a ditch witch. If not rocky or filled with tree roots, it should be easily done in a day. Remember to put a colorful tape in the trench when it is halfway full on the backfill so sombody doesn't dig up your wires or pipes at a later date. Good Luck

1,000 feet in a day with a home depot trencher? That's going to be a very long day. I did one 75 feet between my garage and shed 3 feet deep to bury a power cable and that took a few hours.
