Stemming from at least three incidents where residents across Long Island were robbed by individuals posing as water department employees, one of which occurred in North Massapequa, the South Farmingdale Water District (SFWD) is urging customers to use common sense and precautions to stay safe.

In a statement issued by the water district, officials said that "no one wants to think they may not be safe in their own house. Unfortunately, there are fraudulent people who will try to gain access to your home in order to commit a crime. Therefore, we urge you to use caution when someone claiming to be a water district employee appears on your doorstep to read a water meter, confirm a leak or sell you a water filtration device."

In North Massapequa earlier this month, an elderly woman was burglarized by men posing as water department personnel. Police said that the incident is related to similar ones that took place in other areas on Long Island and are asking residents, especially the elderly, to be careful.

SFWD officials stated that it is rare that anyone from the water district will show up at their home. In fact, 99 percent of visits to residents' homes are by appointment.

"Even if there is an emergency, such as a water main break, we will notify you when we'll be in the area," they said.

In the event that somebody does come to the door claiming to be a water district employee, residents should ask to see his or her identification card and if they have any doubts about their identity, contact police immediately.

"Our employees have been trained by the Nassau County police regarding identification procedures to help identify imposters," officials said.

SFWD officials also urge residents who witness any unusual activity around water well sites in their area, or if they see a van, truck or any persons who do not look as if they are conducting official business, to contact the police department immediately, or the water district at 249-3330.

SFWD officials concluded, "Remember, a little bit of common sense goes a long way in protecting yourself and your family members. Trust your instincts and call the police if you suspect any problems."
