Sewage Treatment Plants Installation and Servicing
We specialise in the design, installation and servicing of sewage treatment plants for homes and businesses not connected to the main sewer network. Our sewage treatment plants, also known as package treatment plants, treat wastewater from domestic, commercial and industrial properties safely on-site, so clean water can be returned to the environment rather than the mains system.
We can offer numerous treatment plant solutions including electric and non-electric options from top manufacturers such as ClearFox and GRAF.
How Sewage Treatment Plants Work
A sewage treatment plant breaks down and treats wastewater using biological and chemical wastewater treatment processes. Waste enters the plant, where solids settle, and natural bacteria break down harmful materials. The result is treated water that can be safely discharged into local watercourses, protecting the environment while reducing pollution risks.
Why Sewage Treatment Plants are Important
If your property isn’t connected to the main sewer, or public sewage works, a sewage treatment plant is essential. It makes sure wastewater is treated properly before it’s discharged into the environment, protects local watercourses from contamination, and helps you meet environmental regulations.
They protect watercourses from contamination and meet environmental regulations. Installing a sewage treatment plant can be a legal requirement for homes and businesses in rural or off-grid locations.
Sewage Treatment Plants Services
Our services cover the design, installation, support and maintenance of any domestic, commercial or industrial sewage treatment plant.
We provide a variety of sewage treatment plants, including electric and non-electric systems. Non-electric systems are often favoured for their low running costs and minimal environmental impact, while electric systems can offer enhanced efficiency and performance in certain situations. Whatever your requirements contact us today and we will help you select the right plant for your property.
Sewage Treatment Plant Installation Process
We aim to provide a seamless installation process, minimise disruption and make it as easy as possible. We conduct a thorough site assessment to understand your property’s specific needs and any local environmental factors. Based on this, we recommend the most suitable sewage treatment plant or design a system that meets your requirements and local regulations.
Our team then handles the entire sewage plant installation process, making sure everything is in place according to the highest industry standards. Once installed, we perform extensive testing to ensure the system operates efficiently.

Sewage Treatment Plant Maintenance and Support
After installation, we offer ongoing sewage treatment plant maintenance and servicing to keep your system running smoothly, whether you have a domestic or commercial system. Sewage treatment plants also need periodic sewage treatment plant emptying to remove sludge build-up. Get in touch with our team to find out more about our tankering services for safe, efficient emptying.
