The Collier County Public Utilities Department was recently contacted by a concerned resident after someone claiming to be from the Water Division wanted to come inside a home and test the water.

The Collier County Water Division will never knock on your door and ask to come inside and test the water. All Collier County Public Utilities Department employees also carry photo identification with them while on duty. If someone comes to your door and asks to test your water, the Water Division urges you not to let them in and to call the Collier County Sheriff’s Office.

In addition, the Water Division also will never send you anything in the mail that says you need to have your water tested. These mailers typically come from companies attempting to sell home water treatment products under false pretenses.

The Collier County Public Water Supply System provides potable (drinking) water service to approximately 302,000 permanent residents – approximately 366,000 in season – in the unincorporated portions of Collier County, from Barefoot Beach to the Isles of Capri.

There are over 68,000 service connections to the Collier County Public Water Supply System.
