What is a septic tank?
Before we proceed to septic tank installation, lets quickly go through a short description of a septic tank. As you have come to this page, definitely you already know about a septic tank. However, it’s better to have the knowledge of a thing you are going to use. A septic tank is a chamber usually made up of concrete, fiberglass, or plastic. It’s an underground container used for the treatment of domestic wastewater (sewage). Septic tanks can be used in areas that are not connected to a sewerage system, such as rural areas. The wastewater runs down to the septic tank through the septic drain field, which provides further treatment. But a disadvantage commonly seen is groundwater pollution may occur and can be a problem.
The term “Septic” is defined as the anaerobic bacterial environment that develops in the tank. It is responsible for the breakdown or decomposition of the solid waste material in the tank. Septic tanks can also be installed with other wastewater treatment units. Such as biofilters or aerobic systems, commonly used for artificially forced aeration.

Before going to install a septic tank, you must have passed a few conditions. In order to install a septic system at your house or field, you must know the law and legislation for installing a septic tank. For a complete guide to the law for installing a septic tank, checkout out our law article. Secondly, you need to perform a site survey where you want to install your septic system. Check your property isn’t in a restricted groundwater protection area. Determine the water table levels where you want to install a septic tank. Check if the ground is suitable for the drainage field area.
Last but not least most important thing is the design of your septic system. You must have created a complete design of your septic system. Whenever you are going to build anything, like a building or your house, you must have a plan. Without planning starting work is not a good option at all. Without a plan, a project is not a cost-saving, but you are at the risk of burning your cash. So, must design a complete plan of your septic system before getting started with septic tank installation
10 step guide

2. Select a suitable place
Select a suitable place where you want to install your septic tank system. Check the available space. Check the ability of soil to drain and filter wastewater.
3. Evacuate a large hole
Make sure it is large enough for the tank and any recommended backfill, then install the right type of base (often a concrete one) for the tank to sit on. Please ensure that you follow the manufactures detailed health and safety guidelines that will be provided in the manual when excavating your hole.
4. Inspect the tank for damage
Tanks will normally have been fully tested and checked before being dispatched to you, but it isn’t uncommon for them to become damaged during transportation and offloading. Make sure to thoroughly inspect the tank when it arrives as, once the tank is installed, most manufacturers won’t accept claims for damage.
5. Double-check the depths
You should have already checked the depth of your incoming pipework during the site survey and design stage of your project and ordered a tank with the appropriate invert levels. However, It is worth checking this again to ensure that the physical tank delivered will still connect to your existing pipework and remain within the maximum permissible depth.
6. Place the tank in a hole
Carefully lower the tank into the hole, using the recommended lifting system, while checking that the inlet and outlet orientation is correct and ensuring the tank is level.
7. Install the inlet and outlet
Should be a straightforward task if everything has gone to plan, but a qualified plumber should be consulted if you are unsure.
8. Install the septic drainage field
This ensures both that the pipes cannot be warped or damaged by heavy loads above, such as vehicles or buildings, as well as making sure that the water from the soakaway won’t enter a watercourse, which is in contravention of new guidelines from the Environment Agency.
9. Backfill and cover
Concrete, gravel, or sand are the most common recommendations, but check the instruction manual to see what the manufacturer advises and follow their steps for adding backfill to the site. Manufacturers will always assume the tank is going to be installed in a traffic-free area. If this is not the case, it is highly recommended that you contact a structural engineer before installing your system.
10. Ventillation arrangements
This can often be overlooked, but it is important to ensure your system is well vented to prevent odor issues on site. Contact our technical team for advice if you are unsure of the best arrangements for your site.
