Over the years, JJID has expanded and diversified into areas of mechanical and waste water treatment in order to better serve clients with utility, drainage and wastewater treatment needs.

JJID performs municipal work including automation upgrades, the rehabilitation of waste water treatment facilities, force mains and pump stations together with the new installation of lift stations and grit chambers. The overwhelming need for renovation and rehabilitation of waste and water plants constructed in the last 40 years has also led to our developing a sub-specialty in this area.Owners, Developers, Municipalities, Construction Managers and General Contractors are often times faced with the construction of new water or waste water facilities in conjunction with the approval of the infrastructure for new development plans. JJID is able to provide a “total site package” including the construction and installation of these facilities.
