After a sludge analysis is performed and the sludge is checked for a reduction in total volatile solids the sludge is pumped from our sludge holding tank to Southern Soil Builder's tanker trucks, which then transport the sludge to the appropriate field. There the sludge is applied to the soil by Southern Soil Builder's equipment and personnel.
