Why Properties Choose Our Sewage Treatment Plants
A sewage treatment plant is a long-term piece of infrastructure. We focus on correct design, quality equipment and professional installation so your system runs quietly, efficiently and stays compliant for years.
Correctly Sized Design
We size the plant around occupancy, flows and site layout so it performs properly under day-to-day use.
Compliance Focused
Our installations are carried out with Building Regulations, General Binding Rules and discharge consents in mind.
Proven Equipment
We work with established plant manufacturers for reliable performance and easy access to parts and servicing.
Cleaner Effluent
Treatment plants significantly improve effluent quality, protecting streams, ditches and groundwater from pollution.
Clear, Fixed Quotes
We provide itemised quotations up front, so you know exactly what is included in your sewage treatment plant install.
Service & Aftercare
We provide guidance on servicing, desludging intervals and can support with future callouts or upgrades.
Our Sewage Treatment Plant Process
Site Survey & Assessment
We visit your property, review existing drainage, check levels and access, and discuss how you use the building.
System Design & Sizing
We calculate flows and occupancy, select the right plant size and plan inlet, outlet and venting requirements.
Groundworks & Plant Installation
Our team carries out excavation, base preparation, plant positioning and main pipework connections with care.
Power, Controls & Outfall
We connect blowers, electrics and control panels, plus drainage fields, ditches or other outfalls as per design.
Backfilling, Testing & Commissioning
We carefully backfill in layers, check levels and flows, then test and commission the plant so it runs correctly.
Handover & Maintenance Guidance
You receive clear instructions, servicing intervals and any documentation needed for your records and compliance.
Common Sewage Plant Problems We Prevent
Many callouts we attend are down to wrong sizing, poor installation or lack of access for servicing. Getting the system designed and installed properly from the start avoids these headaches.
Frequent Alarms & Callouts
Incorrectly sized or badly set up plants can alarm regularly. We design for realistic flows and ensure correct commissioning.
Odours & Visual Impact
Poor siting or venting can cause smells or unsightly covers. We consider wind, access and landscaping in our designs.
Non-Compliant Discharge
If a plant isn’t installed or run correctly, discharges can fail tests. Our installs follow best practice and manufacturer guidance.
Short System Lifespan
Cheap or poorly installed units often fail early. We specify proven equipment and proper installation methods to maximise life.
