Chesterfield is a licensed contractor and installed for Suffolk County I/A Septic Systems (Innovative Alternative Onsite Wastewater Treatment Systems). In attempt to revitalize our local waters through reducing nitrogen emission, Suffolk County Department of Health Services required residential projects located within the high priority area to be equipped with an I/A system. Since their introduction in 2015, Chesterfield has worked to install these systems and help protect our local waters.

Chesterfield also has extensive experience installing conventional  grease traps, distribution boxes, piping and septic systems in Westhampton, East Hampton, Southampton, Greenport, Mattituck, Southold, The North Fork, Suffolk County, Nassau County, Long Island. We will also work with you to ensure the proper inspections, approvals and paperwork has been submitted to the health department.
