Leak in copper water line near street. Best options?

[Kyle Agius]

Hello,

I received a letter(attached) from the city of Casper, WY regarding a small leak in a copper water line at my duplex.  Per my conversation with the city, they shut off water and determined that it stopped the leak on my property, only a few feet from the shut off. They turned the water back on because I guess the leak is pretty minor.

I am just writing to find out a few things as I am pretty new to property ownership and this is the first real issue I have faced.  

1.) Is there any method to get the city to help with some of the expenses of fixing the leak?

2.) How much should an issue like this cost my (considering its a small leak in copper piping about 5 feet deep and assuming about 4-5 feet form the curb stop.)?

3.) Just want to make sure I'm not being taken advantage of as a remote property owner.

Any information the BP community can provide me with is greatly appreciated.

Thank you

-Kyle
