Why NSF 245 Septic Systems are Superior to INRB Systems for Enhanced Nutrient Reduction

Enhanced nutrient reduction systems are the buzz here in Florida. In order to protect our natural resources, we must all do our part to improve the water quality. Septic systems play an important role within our watersheds. Florida has many impaired water basins that require an action plan. These basin management action plans (BMAPs) require a reasonable assurance plan (RAP). These plans will require an enhanced nutrient reducing septic system.

Why NSF 245 Septic Systems are Superior to INRB Systems for Enhanced Nutrient Reduction

At Southern Water and Soil, we believe that NSF 245 septic systems are the best alternative when compared to an INRB or in-ground nitrogen reducing system. We will discuss the difference.

The INRB is a passive system using wood chips as a way of slowing down water. This creates a saturated environment beneath the drain field that helps treat nitrogen. However, the INRB system that is approved has not been tested to reduce nitrogen to 65 percent as touted by some. The INRB can also induce premature drain field failure due to the reduced flow vertically.

The NSF 245 septic systems, like Norweco and Fuji, have been tested by the National Sanitation Foundation (NSF) and have been proven to reduce nitrogen by 67 percent or greater. At Southern Water and Soil, we have designed thousands of Norweco and Fuji systems in the state of Florida. They have a proven track record and increase the longevity of the drain field.

If you need a septic design with enhanced nutrient reduction, then look no further than our team at Southern Water and Soil. We would be happy to discuss NSF 245 septic systems or other options with you.
