    1816: Why York Water?

    Fire almost destroyed York many times in the 1700s and 1800s! To put out fires, the community needed a public water supply with reliable water pressure.

    This Lewis Miller print depicts the first water hydrant test in York.

    1816: Log Pipes

    The wooden water mains did not stand the test of time.  In 1840, they were replaced with cast iron.
