Septic tank/absorption field systems : a homeowner's guide to installation and maintenance
A septic tank/absorption field is the most common onsite sewage treatment system in use in Missouri. Nearly 30 percent of all housing units in Missouri use onsite wastewater treatment systems and most of these are septic tank/absorption field systems. Several surveys throughout the state have shown that 70 percent, or 150,000, of these systems are not functioning properly.
