Hydraulic management of a soil moisture controlled SDI wastewater dispersal system in an Alabama Black Belt soil

► Soil moisture based real-time control over wastewater hydraulic disposal can successfully avoid unfavorable wet drain field conditions. ► The persistent low hydraulic dosing period during winter season is preventing this concept to be applied as a standalone application. ► The distance between the wastewater distribution points and the soil moisture monitoring locations should be optimized to limit soil cracking.
