Aerobic treatment-drip irrigation systems qualify for reduction in setbacks to property lines and foundations due to how accurately drip disposal works. They also qualify for reductions in the required drainfield amount that goes in. Aerobic treatment-drip irrigation systems qualify for a 25% reduction in the drainfield square-footage. The reduction in the required drainfield square-footage along with the small diameter of the drip irrigation line directly relates to a significant reduction of the overall footprint. For example, a 400 gpd flow requires 500 square feet in a trench configuration. The footprint of the drainfield is approximately 18’ x 34’. The same flow for an aerobic treatment-drip irrigation system will require 375 square feet in a trench configuration. The footprint of the dripfield is approximately 14.5’ x 23.5’.
Aerobic treatment-drip irrigation systems eliminate future drainfield repairs. Because most homes use the majority of their water in very short periods of time, primarily in the morning, the drainfield can receive up to 70% of the daily flow in the period of just 1 to 2 hours. This leads to drainfield saturation and overloading. Additionally, because of Florida’s frequent and heavy rains, drainfields are often already saturated with water. Saturation leads to very little oxygen being present in the soil which accelerates the development of the bio-mat.
Aerobic treatment-drip irrigation systems virtually eliminate drainfield failure because the wastewater is treated to such a high degree. There is essentially nothing in the water for the bacteria in the soil to work on so a bio-mat builds at an extremely slow rate if at all. The soils are moistened not saturated because the wastewater is delivered evenly over the entire dripfield. The dispersal of all of the water used in a day occurs over a 24 hour period. The drip line is installed in the root zone so most of the water is taken up by plant roots and used in the growth process of the vegetation. The remainder of moisture is lost through direct evaporation into the air. This allows oxygen to remain in the soil which is vitally important.
