Septic tank installation regulations in the UK
If you're considering installing a septic tank on your property, it's important to know that there are regulations in place in the UK to ensure that it's installed and maintained correctly. These regulations are in place to protect the environment and public health. In this blog post, we'll discuss the septic tank installation regulations in the UK, so you can ensure that your installation is compliant with the law.
Planning permission
Before installing a septic tank, you need to make sure that you have planning permission from your local authority. In some cases, you may also need to get permission from the Environment Agency. If you live in a listed building or a conservation area, you may also need to get additional permissions.
Size of the tank
The size of the septic tank that you install will depend on the number of people living in your property, as well as the size of your property. The larger the property and the more people living there, the larger the septic tank will need to be.
Location of the tank
The septic tank needs to be located in an area that is easily accessible for maintenance and emptying. It also needs to be located away from any watercourses or wells to prevent contamination. The location of the septic tank should be agreed upon with the local authority before installation.
Installation
Septic tank installation must be carried out by a qualified and experienced installer. The installer must follow the manufacturer's instructions for installation and ensure that the septic tank is installed in accordance with Building Regulations.
Discharge
The discharge from the septic tank must not pollute the environment. If you're discharging into a watercourse, you must have an Environmental Permit from the Environment Agency. If you're discharging into the ground, you must have a soakaway system in place that meets Building Regulations.
Maintenance
Septic tanks require regular maintenance to ensure they continue to function correctly. You should have your septic tank emptied by a licensed waste carrier at least once a year. You should also have your septic tank inspected every three to five years by a qualified professional.
New regulations for septic tanks
In 2015, new regulations were introduced that prohibit the use of septic tanks that discharge directly to a watercourse. If you have a septic tank that discharges directly to a watercourse, you will need to upgrade or replace it by 1 January 2020, or earlier if you sell your property before this date.
The new regulations also require all new septic tanks to be installed with a drainage field, which is a system of perforated pipes that allows the treated effluent to soak away into the ground.
In conclusion
Installing a septic tank on your property can be a cost-effective and environmentally friendly way to deal with your sewage. However, it's important to ensure that your installation complies with the regulations in place in the UK. By following the guidelines outlined in this blog post, you can ensure that your septic tank installation is legal and sustainable. Remember, if you're unsure about any aspect of septic tank installation or maintenance, it's always best to seek the advice of a qualified professional.
