Underground Utilities


JJID has the equipment, experience and the skilled personnel necessary to safely and efficiently perform all types of underground utility projects, both large and small. Every year JJID installs miles of underground utilities, from underground utility repairs, partial replacements and water line installations for both private and public utilities to complete water, storm water and sewer systems as part of much more involved site work packages.
