Affordable Septic Servicing Gwinnett County
Septic tank problems cause and lead to drain field problems. The drain field is where the waste water goes after it leaves the septic tank , also called leach field or disposal field. It can also go to a mound, a seepage bed , or a seepage pit . The general and more technical term for all these methods of handling the waste-water from the tank is the soil absorption system. We will begin with the most common type, the drain field or leach field.
|Once sewage undergoes primary treatment in the septic tank, the clarified effluent flows to the drain field, where it is discharged into the soil for final treatment and disposal.
A typical drain field consists of several relatively narrow and shallow gravel-filled trenches with a perforated pipe near the top of the gravel to distribute the waste-water throughout each trench. In most cases, drain fields will perform indefinitely if an effective septic aerator is installed
The Biomat The natural occurring process of waste-water entering your leach field, drain field, mound, seepage bed , or a seepage pit is the formation of the biomat. The biomat (biological mat) comprises of a black, jelly-like mat that builds on the bottom and sidewalls of the drain field trench. It is composed of anaerobic (without oxygen) microorganisms (and their by-products) that attach themselves to soil and rock particles. Their food is the organic matter in the septic tank waste-water. Because the biomat has a low permeability, it retards the rate of flow out of the trench into the drain field soil.
A failing drain field no longer has the capacity to handle the volume of water which it receives. A failing drain field can have these characteristics: the grass is greener over the drain field than the rest of the yard; there are odors in the yard; the plumbing backs up; the ground is wet or mushy over the drain field. The laterals will probably also have standing water in them. These are indications that the drain field is being converted to anaerobic conditions. A drain field that is anaerobic will not function properly and it must be restored to aerobic conditions before it will resume normal operation.
