In some cases, there may be visual signs you have a septic system. They take many forms, including open-bottom chambers, fabric-wrapped pipe, and synthetic materials such as expanded polystyrene media. Some leak around the lid. This evaluation is performed as a service to a developer at no fee and while any individual can request an evaluation it must be signed by the owner of the property to allow MoDNR access for the evaluation. The following is an example on how to calculate minimum lot size for the use an individual on-site wastewater treatment system with subsurface soil (absorption) dispersal on individual lots. A conventional decentralized wastewater treatment system consists of a septic tank and a trench or bed subsurface wastewater infiltration system, known as a drainfield. We can make most of them watertight. Once the grey water, or effluent flows from the septic tank to the pump chamber it is then pumped to the sand filter. Effluent is pumped under low pressure through the pipes at the top of the filter. This can cause ponding in the drainfield, surfacing of untreated wastewater, or backing up into the septic tank and into the plumbing in the house. In many states, a septic system must be inspected with the transfer of real estate. There are charcoal filters available for roof vents that may also alleviate the odors. Regular maintenance is the best method to prevent a septic system failure. In others, it can be more complicated. Many materials that might be poured down the drain do not easily decompose. The gravity septic system is also known as the conventional system. Many times folks believe they can simply restart a septic system by flooding it with a high dosage of pre-treated bacteria to eat up the sludge that might be overloading a conventional tank and causing a blockage. If the geohydrological evaluation indicates a minimum lot size (acres) acceptable to the developer then as described in 10 CSR 20-6.030(3) they should contact a soil scientist, as defined in 701.040(2)(e), RSMo to prepare a detailed soils report for the subdivision.

Some pre-casters build their tanks as two pieces with a bottom and a top. Please remember this is only an example; lot size will vary throughout the state depending upon the geology, soils and topography within any proposed subdivision. I. This list describes nine types of septic tanks and designs, each with different advantages and uses. The gravity effect forces water through a sand layer that filters it so what finally exits is completely clear liquid into the surrounding soil area. They require careful back-filling using small gravel or sand to properly support and protect the tank when filled with water. The effluent is filtered through the sand allowing it to be properly treated. No matter what your preference is for referencing your sewer pump, at Envirotek Systems we can diagnose, repair and install for all your maintenance requirements.
