When it comes to private sewage treatment for a property, you have two main options: a septic tank or a sewage treatment plant. Septic tanks are widely used, but for the most efficient sewage treatment system which clears wastewater to the point it can be released into water courses, a sewage treatment plant is the best option. So, if your septic tank is developing problems or you simply want to upgrade the efficiency of your current system, consider a septic tank conversion.
Septic tank conversion options
There are two different ways to convert a septic tank into a sewage treatment plant. The two methods differ in where the additional conversion equipment is installed.
- ‘Add on’ conversion: this involves adding in extra apparatus after the existing septic tank, thus turning the tank into a primary treatment chamber for a sewage treatment plant. This form of conversion can comply with Environment Agency regulations as the equipment can be tested to EN 12566 standards, receiving a CE mark on passing.
- ‘In tank’ conversion: this adds extra filtering equipment inside your existing septic tank to improve filtration. However, these conversions are not uniform and cannot be tested to to the EN 12566 European Standards for small sewage treatment plants. This means they will not be accepted by the Environment Agency for releasing water into water courses.
Why convert a septic tank into a sewage treatment plant?
Updating your septic tank to a sewage treatment plant is a way to upgrade its performance and wastewater cleaning efficiency. A sewage treatment plant, in simple terms, is like a septic tank with two additional treatment chambers which allow the wastewater to be filtered and treated to a higher degree. If you have an old or faulty septic tank, upgrading your system with the addition of further treatment apparatus improves its efficiency and prevent groundwater pollution.
Septic tank conversion costs
The cost of converting an existing septic tank is generally less than installing a complete, new sewage treatment plant. Provided your current septic tank is an a suitable condition, the conversion will provide you with many years of improved wastewater treatment. A sewage treatment professional will be able to advise you on the condition of your tank, the suitability of your site and on the performance of the new system upgrade.
Further advantages of a septic tank conversion are:
- It’s a cost effective upgrade for an existing system
- Minimises groundworks and reduces the amount of new equipment which needs to be installed
- Installation is quicker and simpler than with a completely new treatment plant
- It’s a low maintenance option with long intervals between tank emptying
- Effluent is clear, odourless and can be released into watercourses
