Septic Tank Regulations

Septic tank regulations were changed with the introduction of the 2015 general binding rules compliance which came into force at the end of 2019 making some sewage treatment systems illegal to operate.

If you are not sure if this will effect you or not why not give us a ring to discuss your current setup and we will be able to let you know if you will be complaint or if we can adapt your current system to make it compliant.

Here are the rules in more detail:

The general binding rules

You must follow the general binding rules if you’re the operator of a septic tank or small sewage treatment plant.

The sewage must:

  • be domestic in nature, for example from a toilet, bathroom, shower or kitchen of a house, flat or business (such as a pub, hotel or office) – contact the Environment Agency if you’re not sure if the sewage is domestic in nature
  • not cause pollution – find out how to check for pollution

There are other rules depending on whether you’re releasing this sewage:

  • to the ground, for example in your back garden
  • to a surface water, for example a river or stream

Ask your local installation or maintenance company if you’re not sure what sort of system you have.

Releasing to the ground

You must use a septic tank or a small sewage treatment plant and a drainage field (infiltration system).

You must apply for a permit if you release (‘discharge’):

  • to a well, borehole or other deep structure
  • more than 2 cubic metres (2,000 litres) per day
  • in a groundwater source protection zone (SPZ1)

Calculate how much sewage you discharge

For sewage from a residential property, use the calculator to work out how much you discharge per day.

For commercial properties (such as a hotel, restaurant or office) or holiday accommodation (such as a cottage or chalet), use British Water’s flows and loads guidance or contact the Environment Agency for advice.

Work out if you’re in a groundwater source protection zone 1 (SPZ1)

An SPZ1 can be either:

  • the area around a commercial water supply shown on the map of protected zones – check whether your discharge is in the inner zone (Zone 1) or ask the Environment Agency
  • any area within 50 metres of a private water supply for human consumption – ask your neighbours if they have a spring, well or borehole, and how far it is from your drainage field

Releasing to a surface water

You must use a small sewage treatment plant. You must apply for a permit if you’re discharging more than 5 cubic metres (5,000 litres) per day. Use the calculator to work out how much you discharge per day.

For commercial properties (such as a hotel, restaurant or office) or holiday accommodation (such as a cottage or chalet), use British Water’s flows and loads guidance or contact the Environment Agency for advice.

Investigate Septic Tank Problems and Install New Soak Away

James and his team came to investigate why our septic tank kept backing up, they quickly identified the problem and gave us options to remedy the issue. Once we instructed them to carry on the work required they quickly and efficiently installed a new 7000 litre soak away pit leaving the site extremely clean and tidy.

I cannot recommend them enough, if you have any problem at all to do with drainage then call James now.
