What are the main types of septic systems in London?


Not just in London, but all over the world, there are various types of septic systems which can be used based on different criteria. The most important septic system is that of the entire country, city, in our case, and to which each individual septic system is connected.

The following types of septic systems can be found in London:
 
  1. the septic tank which is the most common type of system used for household and commercial purposes in London;
  2. the conventional system which consists of a septic tank linked to a wastewater infiltration system, also known as a drainfield;
  3. the chamber septic system which consists of a gravelless drainfield, however, this is seldom found in London;
  4. the drip distribution system which is quite complex, and which is connected to a well and a septic tank which then goes into a drainfield;
  5. the Aerobic Treatment Unit (ATU) which follows the same procedures as the London municipality’s sewage system;
  6. the mound system which is suitable for areas with shallow soil depth or high groundwater in London;
  7. the sand filter system which can be built above or below the ground and which come with several advantages;
  8. the evapotranspiration system which is used in specific environmental conditions, such as London’s weather conditions (these systems do not work in places where it snows);
  9. the constructed wetland system which is suitable for London’s weather conditions, given the fact that here it rains almost every day;
  10. the cluster or community septic system which connects several houses to the central sewage system and which is quite popular in London’s residential areas.

Even if most of these septic systems work in London, there are various aspects consider when choosing the sewage system for your home.

Our emergency plumber in London advises homeowners to choose traditional septic systems, such as septic tanks which work perfectly in the city-state. These are also special things to consider for those living in areas of the city where the water infiltrates in the ground, case in which the evapotranspiration system or the wetland system is recommended.
 

1. Septic tank based systems in London

 
A single septic tank based system in London is made of an underground container or tank which is meant to receive and settle wastewater.
 
The solid materials gather at the inferior side as sludge and the oil, grease, and fat get settled at the surface, forming a layer of scum. Our emergency plumber in London can provide more details on this matter.
 
Anaerobic bacteria, which is bacteria that do not need oxygen, appear in the tank and break down the solid waste.
 
Inside a fully functional septic tank, bacteria can decrease the solid waste by 50 to even 60%. The liquid from the sludge on the inferior side of the septic tank and the top scum (named effluent) pours out from the tank in the disposal site.
 
Then, the sludge and the scum coats are pumped out on a regular basis. This is done by septic pumping companies.
 

2. Conventional septic systems

 
Just like the name implies, the conventional septic tank systems are basic ones. There are two types of conventional septic systems:
 
The septic systems in London which use gravity in order to move the wastewater from the tank into the field;
The septic system which utilizes a pump to move the water.
 
Septic tanks in gravity systems are located on higher grounds than the drain field, which enables the flow of water into the tank and then in the drain field.
 
As about the pressure distribution systems, our plumbers in London can provide detailed information on the subject.
 

3. Can plumbers near me set up alternative septic tank systems in London?

 
These can be:
 
Aerobic treatment units (ATU);
Mound systems;
Sand filter systems.
 
Our emergency plumber in London can offer all the necessary information on these types of alternative septic systems in London.
