The Groveland Water and Sewer Department recently brought in a specialized crew to clean its 800,000 gallon water storage tank, ridding the tank’s floor of naturally-occurring sediment that accumulated over the years since it was first put into service.
The cleaning project was the first that the tank has undergone since the Water and Sewer Department began using the tank in 2011. In order to perform the work, a team of divers took turns suiting up and working their way to the bottom of the tank. Using a tool that functions essentially as a large vacuum, the divers extracted iron and manganese sediment that had collected on the tank’s bottom.
Iron and manganese are two naturally occurring contaminants in public water systems that source their supply from ground water, as Groveland does.
