![]() These inhibit the settlement process in the tank and the biological processes in the drainage field. This progression is accelerated by larger volumes of water produced by a modern home, along with an array of chemicals and detergents in the waste. This can then lead to the effluent leaching to the surface or the drainage backing up to the house. Eventually the flow into the system from the home is greater than the flow out to the subsoil causing the drainage field to back up. This reduces the efficiency of the drainage field and the rate at which it is able to discharge the effluent into the subsoil. Over a period of time fine suspended solids are passed through the septic tank into the drainage field, the bacteria also produce some biomass, silting up the drainage field. ![]() For this process to work successfully the septic tank must be working efficiently and the subsoil be free draining. The drainage field is designed to treat the waste effluent by the action of naturally occurring bacteria. The settled liquid then drains away through soakaway or drainage field. ![]() A septic tank should only need emptying when the solids levels have built up within the tank. This is usually achieved with a number of chambers within the tank and the use of T pipes or baffles. More modern systems are often made from fibre glass or polyethylene.Ī septic tank is designed to settle and retain the waste solids produced from a property. ![]() These can be constructed from a variety of materials including brick or concrete. There are two main types of septic tank applications: Septic tank with a soakaway Septic tanks are designed to collect sewage and wastewater from households that are not connected to the mains sewer. ![]()
