What are the different types of septic systems?
Seepage systems, otherwise known as cesspools, are an older, less commonly used type of septic system. They are constructed by digging a pit approximately five feet in diameter and lining it with concrete rings. The bottom of the rings are filled with rocks. Waste is pumped from the residence into the system, where solid waste is trapped on top of the rocks and biologically broken down by microorganisms, and the effluent is then allowed to seep down into the underlying soil. Most systems installed today are drainage systems, otherwise known as leach fields. These consist of a tank that traps solid waste. Perforated pipes are then laid down in the trenches and covered with dirt. Effluent water from the tank is allowed to leach out of the holes in the pipes while the solids are carried to a cement holding tank for decomposition. In the Pattee Creek drainage system, there are 62 homes with septic systems. All but nine have been inspected. Of these 62 systems, 47 are new and the other 15 h
