This is a low pressure dosing septic system designed for a small school in Tampa, Florida. A low pressure dosing septic system evenly distributes the wastewater throughout the drainfield. This is a more efficient way of disposing of the septic tank effluent than using a dose to gravity system. When you dose to gravity the effluent puddles at the very beginning of the drainfield. Over time this oversaturates and creates a bio-mat. The low pressure dosing system uses the entire drainfield every single dose.
