At R Harvey Drainage, we recently completed another successful sewage treatment plant installation in Sellindge, Kent, delivering a high-quality solution designed for long-term reliability and environmental compliance.
This project involved the installation of a Marsh Nitro Lite 20 population (20PE) combined with a Marsh Phos Lite 20PE system, tailored specifically to meet the needs of the property.
Why This System Was Chosen
The combination of the Nitro Lite and Phos Lite systems provides advanced treatment of wastewater, making it ideal for properties that require:
Compliance with modern environmental standards
A reliable solution for homes not connected to mains drainage
This type of system is particularly beneficial in rural areas across Kent, where septic tank upgrades or new installations are often required.
The Installation Process
Our experienced team managed the full installation from start to finish, ensuring everything ran smoothly and efficiently.
The project included:
Full site assessment
Excavation and preparation of the installation area
Installation of the treatment plant and filtration system
Connection to existing drainage infrastructure
Final testing to ensure optimal performance
We always aim to minimise disruption while maintaining the highest standards of workmanship.
The Result
The finished system provides:
✔ Efficient and environmentally friendly wastewater treatment
✔ Long-term reliability with minimal maintenance
✔ Compliance with current UK drainage regulations
✔ Peace of mind for the property owner
