Replacing a Residential Water Main

More pictures from our water main replacement

The trench to our house partially filled (they do the digging in stages so it’s easier to backfill):


The gas mains (new one is yellow) in the middle of the street.


Our new sewer line and a conduit for the new copper water line going under the sidewalk:


Lowering a trench protector into the pit in the street so the city workers can attach the new water main: IMG_1082

A device they attach to the new copper line to prevent corrosion (it just gets buried with in the pit): IMG_1083

The old water main (c1915):


The old water main cleaned up with drilling device attached:


The results after drilling.  A new tapped valve in the water main.  The puddle is partially from the drilling machine when it relieves pressure in the valve they attached, and partially from rain:


The new water line (3/4” copper) to our house with anti-corrosion device attached.


The shut-off attached to the line at our property line (the metal post coming off the copper line).  You can see where the copper feeds into a conduit.  They used this so they could bury their trench they dug across the street so they could do everything in stages and not shut-down our street for 2 days.

IMG_1099 Overall, we’re quite pleased with the results.  Our water flow has improved, and we don’t have to worry about tree roots in our sewer line causing a backup.

Just waiting for the bill from the city now…
