One2Clean Sewage Treatment Plant

The One2Clean sewage treatment plant sets the industry standard in sewage treatment with its groundbreaking low power consumption. Utilising just 0.59 kW per day—half the usage of typical sewage treatment plants. Ideal for eco-conscious homeowners, it dramatically reduces energy use without sacrificing performance.

With the One2Clean system, you benefit from one of the highest discharge qualities available in wastewater treatment systems. It ensures compliance with environmental regulations and includes optional treatment modules to meet the stringent demands of nutrient neutrality regulations. These advanced features ensure that your home remains harmonious with nature and adhere to the strictest environmental standards.

Tailored for residential use, the One2Clean sewage treatment plant operates at 36 decibels, ensuring your home environment remains undisturbed. Its design is perfect for self-builders and homeowners seeking a solution that blends seamlessly into their living spaces.

Innovative Design Features:

• Flush-to-Ground Lid: The system’s lid is designed to be flush with the ground. Helping to preserve the look of your garden and eliminating any unsightly protrusions.
• Vehicle Loading Lid: This unique feature allows for installation in limited spaces, such as driveways, without compromising space or appearance.
• Integrated Sampling Chamber: The built-in sampling chamber streamlines your quality assurance process, saving you time and money by eliminating the need for additional installations.
• Gravel Backfill: This installation method suits various ground conditions and is cost-effective, saving you significant installation costs compared to traditional methods.
• No Moving Parts: The simplicity of design with no moving parts or electrical components inside the tank makes maintenance easy and efficient. All servicing can be handled via an external control panel and compressor, ensuring a hassle-free experience.
• Optional Raised Outlet: This option saves you time, money, and future headaches. Install your drainage field closer to the surface, reducing excavation costs. As a result you can enjoy improved flow and fewer blockages, while potentially eliminating the need for a pumped outlet.

Choose the One2Clean sewage treatment plant for a sustainable, reliable, and virtually silent solution that blends seamlessly into your home and provides unmatched performance and cost-efficiency.

The One2Clean system is a simple, yet highly effective way to treat wastewater with minimal energy and maintenance. It operates in three efficient stages:

1. Aeration Phase
   Wastewater flows directly into the treatment area, where a diffuser at the bottom of the tank pumps oxygen into the water. This oxygen is vital as it creates the ideal environment for naturally occurring bacteria to thrive. These bacteria start breaking down the organic waste immediately, ensuring the water is treated right from the start of the process.
2. Settlement Phase
   After the aeration phase, the system pauses to allow everything to settle. The heavier solids sink to the bottom, forming a sludge layer. This leaves the clearer, treated water at the top of the tank, ready for the next stage.
3. Discharge Phase
   In the final phase, the clean water at the top of the tank is siphoned off and discharged through the system’s outlet. This treated water is now safe to be released into the environment, whether through a soakaway or other approved method. Once this phase is complete, the entire cycle starts again.

The One2Clean system is known for its efficiency, low running costs, and environmentally friendly operation. By using natural biological processes and avoiding the need for constant pumping or complex mechanical parts, it ensures reliable wastewater treatment for your home with minimal fuss.
