![]() Removing roots from a septic tank costs $600 to $1,600. A septic tank has two baffles-one at the tank's inlet and another at the outlet-to prevent solid waste from clogging the system or moving into the drain field. Repairing a septic tank baffle costs $250 to $900, depending on the type and material. Learn more about our product and septic systems, in general, by navigating through our website, reading the Septic System Owners Manual, downloading the Septic System Report and calling us toll free.To avoid costly repairs, have the distribution box regularly inspected when the septic tank is inspected. ![]() Aero-Stream® has developed a product and process that will fix and restore any type of failed drainfield. The drywell and mound designs are subject to the same failure mode over time they eventually become impermeable so that the sewage outflow from your septic tank cannot be absorbed into the ground.įortunately, you do not have to replace your drainfield to return your septic system to an operational condition. The aerobic bacteria are far more efficient, processing up to 90% of the solids in the septic tank versus an anaerobic system which processes only 40% of the solids in the tank and allows 60% to flow to the drainfield, resulting in biomat clogging over time. Aerobic Treatment Unit (ATU):Īn aerobic treatment unit introduces oxygen into any anaerobic septic system, allowing aerobic bacteria to flourish and convert the system from anaerobic to aerobic. Homeowners must post a bond for potential spills and have to have a contract with an approved sludge hauler. Some schools and other public properties use this system when sewers are not available and no suitable site exists for an on-site septic system. Holding tanks must be routinely pumped to prevent overflows or back-ups into the house. It is most commonly used as a temporary measure to allow continued occupancy of a house until a more permanent fix can be arranged. Holding Tank:Ī holding tank is a self-contained watertight sewage tank which has no outlet for effluent. On sloping sites the down slope area below the mound must remain protected. ![]() Drainage around the mound site is critical if the system is to function properly. ![]() Septic tank effluent is pumped in controlled intervals through the pipes to insure uniform distribution throughout the bed.įinal treatment of the effluent occurs as it filters through the sand and into the natural soil. Within the sand fill is a gravel bed with a network of perforated distribution components, typically PVC pipes. The drywell is typically a secondary chamber added in series after the septic tank or cesspool which allows only the clarified effluent from a septic tank or the gray water to enter. Drywell (or Seepage Pit):Ī drywell is similar in design to a cesspool with an added layer of crushed stone around the outside diameter to increase the absorption area. The pump is activated intermittently by use of a mechanical float device in the chamber where the pump is located. Pressure Distribution Drainfields:Ī pressure distribution drainfield is installed when the site conditions do not allow the drainfield to be installed at a lower elevation than the septic tank outlet, preventing the effluent to flow to the drainfield by gravity.Pressure distribution systems are similar in design to a gravity field and differ only by the use of a mechanical effluent pump to distribute the effluent from the pumping chamber or settling chamber to the drainfield. The size of the drainfield depends on the estimated daily wastewater flow (generally based on the number of occupants), soil type, and soil conditions. Maximum effectiveness of the final treatment occurs when the soil is dry and permeable. The undisturbed soil filters out the remaining solids in the effluent which are then processed by anaerobic bacteria transported from the septic tank in the effluent.The anaerobic biochemical process cleans the effluent before it reaches the groundwater.
