The Marsh ENCO Gravity Sewage Treatment Plant is a high-performance, cost-effective wastewater treatment solution designed for domestic and small commercial applications where mains drainage is not available. Engineered by Marsh Industries, this system delivers reliable, efficient treatment while maintaining low running and maintenance costs.
Built to meet the latest BS EN 12566-3 European standards, the ENCO range provides consistently high-quality effluent that is safe for discharge to a drainage field or watercourse, subject to local regulations and consent conditions. Its gravity outlet design ensures a simple, energy-efficient discharge process, reducing the need for additional pumping equipment.
The system uses a proven multi-stage treatment process combining primary settlement, aeration and final clarification. This ensures effective removal of solids and organic matter while supporting long-term operational stability. The integrated low-energy compressor and high-specification bio-media promote efficient biological treatment with minimal energy consumption.
Designed with installers and end users in mind, the Marsh ENCO features a robust, rotationally moulded tank structure, integral lifting eyes for safe handling, and a keying-in lip for secure installation in a range of ground conditions. Its compact footprint and flexible sizing options (6–16 PE) make it suitable for a wide variety of residential and light commercial projects.
Reliable, durable and easy to maintain, the Marsh ENCO Gravity Treatment Plant is an ideal solution for off-mains drainage where performance, compliance and long-term value are essential.
