12 to 50 Person sewage treatment plants
Sewage treatment plants in this category are suitable for large domestic properties, small groups of houses, campsites, small residential care homes as well as some commercial properties.
For example, a 12 person sewage treatment plant (12PE) will be suitable for up to 2 x 4 Bedroom properties if they are sharing a system.
When sizing the correct plant it is important to consider all the loadings and flows which will pass through the treatment plant. If catering or meal preparation is included in the site activities a grease separator may also be required to ensure the efficient functioning of the system.
If in doubt, please contact us so we can advise you on the most suitable size for your property or project.
We offer a wide variety of sewage treatment plants suitable for large domestic properties or commercial use, accommodating up to 50 people, from trusted providers including Marsh Industries, Klargester, and Harlequin. Explore our full range below.
