How often should I empty my tank?

This of course depends on the size of your sewage tank and the number of people using the
facilities. On average it’s advisable to empty your tank at least annually if you are living in a household of around 3-4 people. You should book your tank empty accordingly.

“it’s advisable to empty your tank at least annually”


What happens if i don’t empty my tank?

The decomposition process in the tank slows down, consequently waste starts to back up rather than drain away. Eventually, you may find your washing machine runs slower or your toilet flush is weak.

As your tank is out of sight it is easy to forget about it. However, the most obvious sign that your tank needs emptying is overflow and water-logging in the area surrounding your tank – noticeable by the foul smell!

Tanks need to be emptied regularly to prevent solid waste eventually building up where it can’t be compacted anymore. As a result, toxins and antibacterial substances build up killing the vital bacteria that break down the waste. Some tank emptying service providers will filter the extraction, because of this they only remove liquids. If this continues, subsequently over time the tank fills up with solids which can damage your septic tank system and cause costly damage. Alton Pump Services remove both solids and liquids and also provide septic tank cleaning services.

Building Regulations 2010 – Drainage and waste disposal

Building regulations state that it is a legal responsibility of the property owner to ensure that their waste treatment system doesn’t ’cause pollution, a health hazard or a nuisance’.

The regulations outline the requirements for septic tanks, drainage fields, cesspits and sewage treatment plants. Local authorities can check that your system is:

  • Correctly located
  • Suitable size for the property (or properties)
  • Appropriate for the local ground conditions
  • Maintained regularly to avoid environmental pollution.

Septic Tank or Cesspit – what’s the difference?

Septic Tank

A septic tank is an underwater sedimentation tank used for wastewater treatment as a result of biological decomposition and drainage.

A septic tank can come in all different shapes and sizes. Older tanks may be brick built or concrete, modern ones are made of reinforced plastic. Septic tanks differ to cesspits as they are not sealed. Bacteria inside the tank breaks down the solid waste decomposing it more rapidly allowing the liquids to separate. As a result that they drain away through the gaps in the brickwork into the surrounding soil.

Septic tanks don’t have any mechanical parts or perform any treatment of the waste. The process is:

  • Waste enters the tank.
  • Next waste separates into three different layers
  • Middle layer of separated waste water leaves the tank via soakaway system.
  • Solids are broken down due to the bacteria

A soakaway system is a network of slotted or perforated pipes, these allow the waste water to percolate through the sub soils. Any remaining contents of the tank are removed at regular intervals by a tank emptying company.

Cesspit / Cesspool

Put simply a cesspit is a holding tank for waste. Waste does not soak away – it stays there until the tank is emptied. There is no treatment of the waste that goes in, it simply separates into three layers within the tank. Because of the gas build up in the pit an exhaust is used to allow the gases to escape. As a result of the toxic, untreated nature of the waste, cesspits pose a greater threat to the environment if they fail. Cesspits require more emptying than septic tanks which can become expensive, so consequently they are not as common.

Does your tank emptying service remove solids as well as liquids?

Septic tanks need to be emptied regularly to prevent solid waste building up where it can’t be compacted anymore. Some tank emptying service providers will filter the extraction and only remove liquids. If this continues, over time the tank fills up with solids which as a result can damage your septic tank system and cause costly damage. Contact Alton Pump Services to have your tank professionally emptied. Call 01420 612162.
