SEPTIC TANK TREATMENT CHICAGOLAND WITH RON’S TIDY TANK SEPTIC SERVICE

A Septic is a private sewage disposal system installed in rural areas where city sewer is not available.

While all septic systems are individually designed for each site, most septic systems are based on the same principles.

septicimageA typical gravity septic system consists of a septic tank, a distribution box or drop boxes and a drainfield, all connected by pipes called header lines. Your septic system treats your household wastewater by temporarily holding it in the septic tank where heavy solids and lighter scum are allowed to separate from the wastewater. The solids stored in the tank are decomposed by bacteria and later removed, along with the lighter scum, by your professional septic tank service Chicagoland. State code requires a few inches be left in the tank allowing bacteria to be present at all times.

After the partially treated wastewater leaves the tank, it flows into a distribution box or drop boxes which separate the flow into a network of septic lines buried one to three feet below ground surface. Drainage holes in each line allow the wastewater to slowly drain into gravel trenches. This effluent then slowly evaporates and seeps into the subsurface soil where it is further treated and purified. The gravel & soil in a drainfield act as biological filters. As the wastewater percolates to the groundwater below, the filtration process and organisms in the soil work together to remove toxics, bacteria, viruses and other pollutants from the wastewater. Soil particles chemically attract and hold sewage nutrients, metals, and disease carrying organisms. This process can effectively treat the wastewater to an acceptable level that will not contaminate the groundwater.

The majority of new septic tank systems in Chicagoland installed now require a Class I or Class II aeration device. The typical installation then consists of a trash tank (septic tank), an aeration device and a lift station (for a pressurized system). The effluent flows by gravity from the septic tank directly to the aeration devise for purification. The treated water then exits the aeration devise by gravity to another tank with an effluent pump (the lift station). The water is then pumped to the septic system; a conventional drop box, Wisconsin Mound, Drip Irrigation, etc.
