Choosing the Right Sewage Treatment Plant

The best sewage treatment system for your property depends on your occupancy, land layout, and whether the site is used full-time or seasonally. For a domestic property in the UK, the size of sewage treatment plant required is determined by the number of bedrooms.

You must allow for:

• Bedroom 1 = 2 people
• Bedroom 2 = 2 people
• Additional bedroom = 1 person

For example, a four-bedroom house requires a 6-person system (2+2+1+1=6).

If the sewage treatment plant needs to serve multiple properties or is for commercial/non-domestic applications, please contact us for help via phone or email.

Sewage Treatment Plant FAQs

What is a Sewage Treatment Plant?

A sewage treatment plant is the modern off-mains solution instead of a septic tank.  It is an underground tank that treats sewage to a much higher standard than a septic tank, producing clean, environmentally safe effluent. These systems are designed for UK off-mains properties and are suitable for homes, commercial sites, and rural developments where connection to the mains sewer isn’t possible.

What are the benefits of Sewage Treatment Systems?

Modern sewage treatment plants offer cleaner discharge, lower environmental impact than a septic tank, and full compliance with the Environment Agency’s General Binding Rules. They are reliable, low-maintenance systems that keep effluent treatment on site, helping protect local watercourses while supporting sustainable long-term use. WTE’s UK-built plants provide high performance, low running costs, and decades of dependable operation.

 How much does a Sewage Treatment Plant cost?

The cost of a sewage treatment plant in the UK typically starts from £1,470 + VAT, but the final price will depend on several factors, including your property size, ground conditions, and whether you need a domestic or commercial system'

There are also many other site-specific considerations, including installation depth, type of system required (ASP, MBBR, or non-electric), and discharge point.

Here at WTE, we have:

• QUANTUM: from £1,470 + VAT (economy domestic systems)
• VORTEX: from £1,980 + VAT (standard domestic systems)
• CYCLONE: from £1,800 + VAT (commercial or multi-property sites)
• FilterPod: prices vary depending on tank size and configuration (non-electric systems)

Your overall water treatment plant cost also includes installation and long-term running costs.

 What different types of sewage treatment systems are available?

There are three main types of sewage treatment systems used in the UK: ASP (Activated Sludge Process) systems like QUANTUM and VORTEX, MBBR (Moving Bed Biofilm Reactor) systems such as CYCLONE for larger or commercial sites, and non-electric systems like FilterPod, which are ideal for off-grid or seasonal properties. Each system treats wastewater differently and suits different site conditions and occupancy levels. Read more about how each sewage treatment system works in our full guide.
