When it comes to managing wastewater effectively, having the right sewage treatment system in place is crucial—not just for compliance, but for the health of your property, community, and environment. Whether you own a residential home or a commercial facility in Dorset, understanding your options for sewage treatment plant solutions is essential.
At Pro Sewage Treatment, we specialise in bespoke sewage solutions across Dorset and the surrounding South Coast. From professional sewage treatment plant installation to scheduled maintenance and innovative field services, we’re here to keep your system running safely, smoothly and sustainably.
Let’s explore what makes Dorset’s sewage treatment needs unique—and how our tailored services can help you stay compliant and worry-free.
Get in TouchDorset’s diverse landscape—spanning coastal towns, rural villages, and heritage areas—poses specific challenges for waste management. Many rural properties aren’t connected to the mains sewer, meaning off-mains drainage systems such as septic tanks and sewage treatment plants are a necessity.
According to the Environment Agency, property owners are legally responsible for the maintenance and performance of their off-mains system. The General Binding Rules also specify that discharges from treatment plants must meet strict standards to protect local watercourses, particularly in Areas of Outstanding Natural Beauty (AONBs) like much of Dorset.
Learn MoreInstalling a sewage treatment plant is a long-term investment—and one that must be carried out correctly from the start. At Pro Sewage Treatment, our installation service begins with a full site assessment, where we evaluate:
Ground conditions and drainage fields
Property usage and wastewater volume
Environmental impact and compliance needs
We offer both gravity-fed and pumped systems, depending on site elevation and soil types. Our technicians only install trusted systems from UK-certified manufacturers such as Klargester, WPL, and BioDisc—ensuring durability, eco-efficiency and easy access for future servicing.
Contact our TeamIf you already have a system in place, regular sewage treatment plant maintenance is the best way to protect your investment. Neglecting this crucial step can result in odours, blockages, pollution—and potentially hefty fines.
We recommend an annual service plan which includes:
Full system inspection
Sludge level checks and de-sludging
Air pump and motor servicing
Electrical and alarm checks
Discharge testing (as per EA guidelines)
Our Dorset-based team offers fast response times and flexible appointment slots, ensuring minimal disruption to your day-to-day operations.
