Working with a variety of municipalities, Posillico offers services and knowledge to provide municipalities with continuous plant operations during the course of infrastructure upgrades to existing facilities. We oversee and install upgrades to existing plants and can provide any maintenance needed. We also have significant experience and ability to construct entirely new wastewater treatment plant facilities. Expanded capacity of wastewater treatment plants and the construction of new plants directly contribute to improvements for local residents and businesses and their waste removal as well as removing contaminants in groundwater and the local waterways of Long Island.
