  Variations within Septic Tank systems
  
  Traditional septic tanks contain two rectangular chambers: the main one being 2/3 of the whole and the second 1/3, usually built with brick or concrete. Strict design rules are in place and septic tanks must be designed as per BS 6297 1983. The inlet pipe into the first chamber ends in a 'T' pipe which travels down the at the least 450mm (18") following top water level (TWL), and the chamber must be a minimum of 1500mm (5'-0") serious from TWL. This first stage chamber is usually twice as long as it is wide. The pipe in the first chamber into the other chamber consists of an 'H' pipe along with the bottom of the pipe is a min. of 300mm (12") below TWL in the first chamber and 450mm (18") below top water level (TWL) when it enters the other chamber. This second stage chamber is frequently square. The outlet pipe from the second chamber of the tank also consists of a 'T' pipe with the lower of the pipe 300mm (12") below TWL.
  
  Vent pipes should be installed from the first and second chambers with regard to venting the gases, mostly methane and hydrogen sulphide, that are produced by the sludge. Strong covers should be placed completely on the septic tank to stay away from children / animals falling into the tank. There are many cases of thcovers collapsing and many people have been killed as a result.
  
  Nowadays, septic tanks are stated in GRP and polyethylene which often commonly are spherical of form with a narrow shaft at the top to a manhole ground level. These do not produce the same quality of effluent since two chamber tanks and cannot be placed in front of many conversion units.
  
  Care should be taken so that problems will not occur as a result of tank rising out of the ground, when it is usually emptied in high mineral water table sites. It is actually advisable to install the tank which includes a concrete surround.
  
  Septic container effluent still contains about 70% with the pollutants in the original sewage and needs further treatment inside soakaway to prevent a pollution problem.
  
  Soakaways together with Septic Drainfields
  
  The Septic Tank only provides the first the main sewage treatment process. The soakaway is the underground soil treatment system which uses aerobic bacteria found naturally in the ground to further address the effluent. The soil type ought to be suitable for a soakaway to figure properly. Percolation tests are necessary to determine whether a septic tank soakaway would work. If the soil is actually clay, it is not well suited for a soakaway and some sort of drainage problem is inevitable. If you have this issue then a sewage treatment plant could be the answer as they cannot need a soakaway.
  
  The soakaway consists of either several trenches containing perforated conduit laid on and surrounded by stone, or a great absorption bed, or some sort of soakaway mound, all of which are connected to this septic tank outlet by the pipe. In all cases the soakaway must be at the least 1. sewage treatment plant, cesspool cesspits installations, sewage treatment plantSeptic tanks are integral component of a septic system, and a septic system is a small sewage treatment plant.
