Biofilters
Septic tank and Ecoflo biofilter installation.
Biofilters offer a natural way to treat wastewater, combining physical and biological processes to remove contaminants.
Premier Tech’s Ecoflo biofilter takes this process a step further by using renewable coconut husk fragments to filter wastewater. The best part? This sewage treatment system requires no electricity, making it one of the most sustainable options available.
Sequencing batch reactors
Rewatec Solido Smart sequencing batch reactor installation.
Sequencing batch reactors (SBRs) use energy to aerate and treat household wastewater in optimised cycles.
Premier Tech’s Rewatec Solido Smart stands out in this category for its reliability, flexibility, and energy efficiency.
This treatment plant reduces electricity costs by using intermittent aeration cycles. This is different from competing products, which continuously force air into wastewater, requiring electricity 24 hours a day and increasing energy bills.
The Rewatec Solido Smart can also be programmed to handle variable loads, offering more flexibility than similar systems that require a constant inflow of wastewater.
The size and capacity of a sewage treatment plant are primarily determined by population equivalent (PE). PE refers to the estimated amount of wastewater generated by a person per day, which helps to define the plant’s required capacity.
For instance, a typical household of four people might need a system with a capacity of 5 to 6 PE. Larger households may require a system designed for 10 PE or more. The higher the PE rating, the larger the system needed to handle the wastewater.
Quality and construction
While the size and capacity of a sewage treatment plant are important, the quality of the tank also plays a role in determining the cost. Two tanks of the same size could vary in cost, depending on the durability and overall quality of the materials used.
Discharge area
The discharge area can also influence the cost of a sewage treatment plant. There are two typical discharge options: ground discharge and watercourse discharge.
If treated wastewater is discharged to a drainage field, the septic system is relatively simple, which helps lower costs.
Watercourse discharge is a bit different. It requires more advanced treatment technologies or “bolt-on” systems. These additional components are necessary to meet environmental regulations and can increase the overall cost of your project.
A home's wastewater output determines the size and capacity of the treatment plant — two key factors that affect cost.
A site assessment is a crucial first step before installing a domestic sewage treatment plant. It identifies your treatment technology options based on your property’s conditions and local regulations.
The process includes a percolation test to evaluate how well your soil can absorb treated wastewater. Other factors, such as groundwater levels, site topography, and proximity to water sources, may also be assessed to ensure a safe and compliant installation.
At Premier Tech, we offer free site visits in the UK to help homeowners better understand their options. Our experts will assess your property and ensure compliance with all local regulations.
System design
System design involves selecting the right sewage treatment plant for your property and sizing it based on your household’s needs. It also includes creating detailed plans for the system’s layout.
Premier Tech provides free system designs as part of its installation services. It’s a money-saver for our clients as the typical cost for system design is anywhere from £500 to £1,500.
Premier Tech's free site assessment for residential properties in the UK.
The installation process is where the rubber meets the road. It covers site preparation, excavation, and the actual placement of your sewage treatment plant.
Assuming your site has permeable soil, a gentle slope, and easy access, the cost to install a sewage treatment plant starts at £7,000 to £8,000. Costs are higher for more complex sites.
At Premier Tech, our experienced team can handle the installation of your system. With decades of expertise, we make sure you get the right system and that it’s installed correctly — the first time.
Regulatory fees
Installing a domestic sewage treatment plant may involve some fees and permits to ensure compliance with regulations.
- Planning permission fees
You need to get planning permission if you’re installing a sewage treatment plant in a new location or if you’re expanding your site and need a larger system. The fee is usually around £350. Permission and fees are not required if you’re replacing an existing system with one of a similar size.
- Environment Agency permits
You don’t need a permit from the Environment Agency if your system discharges less than 5,000 L per day and complies with all requirements of the General Binding Rules. If your system doesn’t meet these rules, you will need to apply for a permit and pay the application fee of £125 .
At Premier Tech, we offer a complementary consultation to help you navigate this process. Our team provides guidance on planning permissions, permits, and all necessary documentation, making it easier to get your system approved.

Get multiple quotes
A domestic sewage treatment plant is a major investment and it’s important to shop around. Don’t settle for the first company you find and don't always go with the cheapest option.
Instead, take time to get quotes from at least three reputable companies. A quote should give a detailed scope of works, including treatment units, parts, materials, labour, installation, and any additional services.
To protect yourself, be sure to ask about hidden costs like disposal fees or charges for remote or challenging sites.
By comparing multiple quotes, you can identify areas where savings might be possible and choose professionals that best meet your needs.
