Who owns the water service line in Glendale, CA

The division here is not where most water answers divide. Glendale Water & Power maintains the service connection - you do not arrange that work or pay for its upkeep - but the charges for installing a connection "shall be at the expense of the owner of the premises", so a new or upgraded service is your cost even though the department does the work, at a schedule of charges adopted by council resolution and held at the department rather than printed in the code. Ask for that schedule before assuming a figure. Note also that the meter is the department's own, which it owns and installs, and that your other pipe answers the other way entirely: the same City makes the sewer house connection yours to maintain, wye or saddle at the main included. One last thing, and read it for what it is. The nearest the code comes to drawing a line is a clause about what the City will not be blamed for: damage from water used "beyond its meters", or past your property line where the meter is not in the public right-of-way. That tells you where Glendale puts its own risk, and it is the best signal in the code - but a clause about liability is not a statement about who owns or repairs the pipe, and it should not be read as one. If the leak is out towards the street, ring Glendale Water & Power and ask them to tell you which side of it you are on. And one thing to check before you rely on any of this: the State's register puts the City's system over about two thirds of Glendale's land and Crescenta Valley County Water District's over about 3% - if Crescenta Valley bills you, its own rules apply. Most of the rest, a little over a quarter, is ground inside the city limits that no published water service area reaches - not a rival utility, and not necessarily unserved. Check the name on your water bill.
