one2clean

Fully certified to EN12566-3 & S.R. 66:2015, the one2clean is a packaged on-site wastewater treatment system suitable for domestic houses and small developments.

The one2clean wastewater treatment system (also known as sewage treatment plant) is the benchmark for low running costs and treatment efficiency. Available in both gravity and pumped discharge options, it seamlessly integrates with gravity percolation trenches, a low-pressure pipe network (soil polishing filter), or a tertiary filter to meet planning application requirements and ensure compliance with local authorities.

Designed for energy efficiency and minimal maintenance, it delivers exceptional performance while keeping operational costs low, making it an ideal, cost-effective solution for homeowners.

✓ Safely treat and dispose of your wastewater.

✓ Available in gravity or pumped discharge.

✓ Suitable for 5-18PE (houses and small developments)

✓ SBR technology operates in cycles and only runs for 11 hours each day.

✓ Silent and odourless treatment process - operates at 36 decibels.

✓ No moving parts or electrical components in the tank.

✓ Can be installed in driveways using a vehicular cover.

✓ Free delivery and commissioning anywhere in Ireland.

Design & Planning

The design process for an on-site wastewater treatment system begins with an EPA site suitability assessment, a critical step to determine the most appropriate system for your site. This assessment evaluates soil percolation, topography, and site-specific conditions, ensuring compliance with EPA and local county council regulations. Key considerations include maintaining minimum separation distances from the water table, bedrock, property boundaries, wells, nearby dwellings, and public roads. These factors influence the safe treatment and disposal of your wastewater and determine whether a standard septic tank or wastewater treatment system with percolation trenches, a low-pressure pipe network, or an advanced tertiary filter is required.

Installation

one2clean wastewater treatment systems are designed with installation in mind, offering factory-designed lifting points to ensure quick and straightforward handling. The lightweight modular tank design makes transport and placement easy, even on sites with limited access or poor ground conditions. For most sites, we recommend a gravel backfill, while a lean mix is preferred in areas with a high water table to ensure stability. Each system has all the necessary fittings and connections, making the installation process efficient and hassle-free. With clear guidelines provided by our experts, you can confidently complete the installation, even in challenging locations.

Commissioning

When the one2clean wastewater treatment system has been installed, and power is available, one of our service technicians will commission the system to ensure it has been installed correctly and is fully operational. This process includes a thorough check of all components to verify proper functionality and compliance with installation standards. Upon completion, we provide a commissioning certification digitally delivered within minutes, which can be shared directly with your engineer for their records. This ensures peace of mind and confirms that your system is operational and complies with your planning application and local county council regulations.

Service & Maintenance

Regular service and maintenance are essential to keep your on-site wastewater treatment system performing at its best and to preserve the useful life of your components. Typically, one routine service callout is required every 12 months, during which our service technicians perform a comprehensive inspection and maintenance process. This includes checking the control panel and operation/fault menu, replacing the air filter (if applicable), and conducting functional checks of all mechanical and electrical components, such as the control panel, air compressor, water pump, valves, high-level alarm, and pipework. The structural condition of the treatment system, including the percolation area, is also inspected.

Additional services may include flushing and cleaning the low-pressure pipe network, measuring pH and oxygen concentration levels for optimising air compressor operating times, conducting a sludge volume proportion test (SV30) to determine accurate de-sludging intervals, and effluent sampling with laboratory testing, where required. Upon completion of the service, you will receive a full digital report within minutes, along with automated reminders for future service calls. Our services also include providing receipts for your local county council as part of your service and maintenance contract or planning application, ensuring your system complies with all relevant regulations.
