Green-tech launches first closed-loop subterranean irrigation system - Mona Pluvia

Accredited Supplier, Green-tech has launched the latest evolution of its renowned Mona irrigation system – Mona Pluvia, the first closed-loop subterranean irrigation system.

Building on over 40 years of research and development, Mona Pluvia transforms water management in urban environments, ensuring efficient and sustainable irrigation while minimising water wastage. This cutting-edge system includes technology that futureproofs a tried and tested irrigation method into a more intelligent use of water fit for our changing climate. The system cleverly collects and utilises rainwater to deliver essential hydration directly to tree and plant roots in urban areas.

At the core of the Mona Irrigation System is passive irrigation technology, a natural, low-maintenance method of watering that includes processes such as capillary action. The subterranean yellow Mona tanks act as underground reservoirs, storing water at the root level and releasing it gradually as needed.

Key Benefits of Mona Pluvia

• Intelligent Water Management: Automatically responds to soil moisture levels to deliver water precisely when needed.
• Sustainable, Closed-Loop Water Use: This system captures and reuses rainwater, eliminating water wastage and reducing reliance on the mains supply.
• Proven Capillary Action Technology: Works with nature to optimise plant hydration and root health.
• Drought Resilience Built-In: Maintains consistent soil moisture during dry periods, reducing plant stress and improving survival rates.
• Low-maintenance design: This design eliminates the need for regular surface watering, saving time, reducing run-off, and minimising labour costs.
• Ideal for Urban & Hard Landscaping: Designed for city tree planting, parks, streetscapes, and green infrastructure projects.
• Supports Climate Resilience: Helps urban areas adapt to changing rainfall patterns and water shortages.
• Manufactured in the UK: Incorporating decades of irrigation experience.
   

The next generation of intelligent irrigation

Planting in urban environments is a key contributor to improving biodiversity within cities and towns. By harvesting and recycling rainwater, resources are utilised to reduce the impact of flooding by removing water from the sewerage network. Mona Pluvia works with the planting's natural feeding pattern while recovering water that ordinarily enters an urban drainage network. This ensures a more natural hydration cycle for trees and plants and supports long-term sustainability in urban landscapes.

Specially designed sensors detect when the tank's water level drops below a set threshold, prompting the pump to refill the Mona yellow tanks with harvested rainwater. This closed-loop system reduces water wastage while promoting a more natural and sustainable irrigation process.

A major year for Green-tech

In addition to launching Mona Pluvia, the TreeParker System was nominated for the Big Innovation Pitch at Futurebuild 2025. This recognition highlighted Green-tech’s ongoing commitment to revolutionising urban tree planting and sustainable drainage solutions (SuDS).

Seraya Sigsworth, Head of Green Blue infrastructure at Green-tech, comments, “Mona Pluvia presents a major step forward in sustainable urban irrigation. By harnessing rainwater, this system significantly reduces water waste while ensuring that trees and plants in urban environments receive the hydration they need. We unveiled this innovation at Futurebuild 2025, and I was delighted at how well it was received. Visitors to the stand appreciated how it could support them with projects to provide greener, more resilient cities.”

Taking green assets that naturally provide biodiversity and combining them with water management creates a true vision of sustainable blue-green infrastructure. For more information, please contact Green-tech on 01423 332100 or visit www.gtspecifier.co.uk
