Welcome to the Greater Lawrence Sanitary District website.
As a wastewater treatment facility, our organization supports five communities in northern Massachusetts and southern New Hampshire Lawrence, Methuen, Andover, North Andover and Salem, New Hampshire. Our purpose is to preserve the Merrimack River and to protect it for enjoyment and use today and in years to come.
