It basically offers protection against the possibility of costly repair bills and covers any service line damages from the curb stop to the outside wall of your home or building.
It's not as complicated as it sounds.It might surprise you to know that the pipe that carries water from your curb to your house is on your property and is actually owned by you. Unfortunately, if something would happen to that line, (a leak or break, etc.) it would be your responsibility to repair it.
Under the Lateral Maintenance program if anything happens to your water service line, MABL will make the repair at no additional cost to you.
