INRB Systems
In-ground nitrogen reducing biofilters designed to protect Florida springs and groundwater.
In-ground nitrogen reducing biofilters are increasingly required in Florida's springs protection areas. We build them to state specification, including the sand and lignocellulosic media layers that do the nitrogen reduction work.

- They are typically required on lots inside springs protection or Basin Management Action Plan areas, including much of the Crystal River and Homosassa area.
- Can you install and permit an INRB system?
- Yes. We design, permit and install INRB systems to current Florida Department of Health standards.
- Do INRB systems need special maintenance?
