Water laying in your yard can be caused by numerous things such as a leaking water line, a wet weather spring or possibly a leaking sewer line. One of the simplest ways to determine if it is city water is to run a chlorine test. If the test comes out positive, call the Municipal Authority of Westmoreland County, and they will further assist your problem. If the test comes out negative, then you need to call FTMSA. If you do not have the ability to run a chlorine test, please call FTMSA and we will assist you.
