— Gravel Drain Field Gravel based drain fields are one of the most common designs used in septic systems This design features a bed of gravel with perforated pipes laid on top The effluent is then dispersed through the gravel and absorbed by the surrounding soil Gravel based systems are generally low maintenance and can be easily

Yêu cầu trực tuyến →— Most commonly drain fields will have a series of perforated pipes that will get buried in trenches that are filled with gravel There are other ways to construct a drain field but this is perhaps the most common way available If you have a sloped property you will want to make sure that it is installed across the slope line
