2020 septic tank regulations


​Under the code of practice implemented by the Environment Agency (General binding rules: small sewage discharge to a surface water), homeowners are responsible for the installation and maintenance of the sewage treatment system on their property and to limit its impact on the local environment.

If buying or selling a property, you are now legally required to inform any potential buyers in writing if the property has a septic tank as well as provide all information regarding maintenance requirements and the location of the system.
2020 Septic Tank Regulation Handbook

​What is the situation?

Since January 2015, new rules relating to sewage treatment discharge came into effect in England and Wales. All direct discharge from a septic tank into a watercourse, such a river, a lake or a stream, will no longer be permitted. An upgrade or a replacement of the existing septic tank will be required.

Meaning now, in order to comply with the 2020 septic tank regulations in England and Wales, homeowners will have to use a small sewage treatment plant to treat the sewage.  These package treatment plants treat wastewater so it’s clean enough to be discharged to surface water.

Who is affected by the 2020 septic tank regulations?

Any homeowner, in England or Wales, who currently has a septic tank directly discharging into a watercourse or causing pollution. Moreover, if you buy a property with a non-conforming septic tank before 1 January 2020, you now have to upgrade it – the responsibility for the replacement tank will have to be settled between the property buyer and seller. For further information, you can download our dedicated e-book.

What are the deadlines?

The upgrade to your sewage treatment system must be in place by January 1, 2020, or when you sell the property (if selling before this date).

Besides, if the Environmental Agency finds out before 2020 that you are currently polluting surface water as a result of discharge from a septic tank, you will be required to install a new system before the new regulations are actually enforced. In such situations, you will be given one year to upgrade, although this will be decided on a case by case basis.

What are the options?

If your septic tank is discharging directly into a watercourse, three solutions are available:

  1. Connect to the main sewer. However, this is unavailable in a lot of remote areas. If there is an obstacle in the way to the public sewer, you may not be able to connect to it either.
  2. Install a drainage field. This option is also known as an infiltration system and allows the septic tank to discharge to the ground instead of the watercourse. Please note that, in many cases, the installation of a drainage system is not possible due to site constraints such as small space and/or the soil not having sufficient drainage potential such as clay soil.
  3. Upgrade your septic tank with a small sewage treatment plant, thus eliminating the need for any drainage field.

For the latter option, the Tricel Novo sewage treatment plant is a suitable cost-effective solution for a septic tank upgrade. It is simple, reliable, easy to install and complies with the environmental legislation.

In fact, all Tricel wastewater treatment plants have been tested to European certification EN 12566–3 and comply with the requirements of S.R. 66:2015. This certification tests all plants for strength, water tightness, durability and treatment efficiency.

By using a wastewater treatment plant which is CE certified, homeowners can rest assured that they are compliant with the standards currently in force, which guarantees a high level of security and efficiency.

​Tips to a hassle-free septic tank or sewage treatment plant

Sewage treatment plants provide treatment of the wastewater inside a tank whereas septic tanks separate the solids from the liquid in the tank and use a percolation area or sewage treatment filters after the tank to provide the final treatment of the effluent.

A quick way of identifying the solution type that your property employs is by applying the following parameters:

  • Most sewage treatment plants require power to run the aeration and carry out the wastewater treatment process; septic tanks do not.
  • A septic tank generally requires emptying once per year, where sewage treatment plants get emptied at intervals of three to sixty months.
  • The level of treatment from a sewage treatment plant is very high, allowing for discharge directly to a stream, ditch watercourse or drainage field.
  • A septic tank produces a much more pollutant effluent which must be discharged to a drainage field for further treatment from natural aerobic soil bacteria in order to process the effluent to an acceptable purification level equal to that of a sewage treatment plant.
