RainBox™ is AgriWater’s advanced water treatment technology that applies the RainBox Advanced Oxidation Process (R-AOP) to water. During the process, reactive oxygen species, including hydroxyl radicals, are generated in pressurised flowing water through reactions involving oxygen and hydrogen peroxide under controlled conditions. Following treatment, the reactive species naturally dissipate, and the process components break down into oxygen, carbon dioxide, and water. The R-AOP process modifies certain physical and chemical characteristics of the treated water, providing a water treatment solution for agricultural irrigation applications.
Independent Research
It’s Not NPK — It’s Oxygen Stress
Independent agronomists confirm: waterlogged soil can severely stress corn roots in 70 hours and collapse yield by 100–200 bu. Water and oxygen compete for the same pore space — and oxygen must win.

What is the RainBox?
Soil Treatment Process
-
Step 1: Water Penetration
Water with high gas content and lower viscosity penetrates deeper and distributes more widely.
View -
Step 2: Soil Aeration & Compaction Relief
Entrailed O2, CO2, and N2 gases improve the soil profile's structure.
View -
Step 3: Aerobic Soil Life Support
Supports microbial activity and beneficial organisms across the profile.
View -
Step 4: Release of Tied-up Nutrients & Minerals
Water movement and microbial action unlock vital nutrients.
View -
Step 5: Reduced Stress on Roots
Healthy soil = strong, stress-free root development and function.

Benefits of RainBox™ Technology
Cleaning Of Irrigation
Removes buildup in pipes and nozzles for optimal system performance.
View
Soil Regeneration
Breaks salt bonds and aerates the soil for improved root growth and biology.
Enhanced Water Absorption
Makes treated water more bioavailable for maximum plant uptake.
Increased Crop Yields
Improved nutrient uptake leads to stronger, more productive crops.
Sustainably Engineered
Designed to reduce environmental impact while maximizing results.
Carbon Reduction Support
Enhances soil carbon cycling and sequestration capabilities.
Water Saving Technology
Reduces irrigation frequency and volume requirements.
Before vs After RainBox™
Transforming common irrigation challenges into competitive advantages through Advanced Oxidation.
Legacy Maintenance
Weekly filter cleaning and monthly dripper maintenance due to organic build-up and mineral scaling.
VS
Self-Cleaning System
Extended maintenance intervals as R-AOP treatment supports irrigation system upkeep and helps limit organic build-up and mineral scaling.
Nutrient Lock-out
Foliar and soil-applied minerals get "tied up" in complex soil bonds, becoming unavailable to the plant.
VS
Maximum Availability
Treated water can support mineral mobility and improve irrigation efficiency.
Slow Stress Recovery
Extreme temperatures and irrigation fluctuations cause prolonged plant stress, reducing overall yields.
VS
Rapid Rebound
Plants experience more stable growing conditions under more consistent irrigation management.
Resource Waste
Inefficient water infiltration and fertilizer run-off lead to higher operational costs and environmental impact.
VS
Precision Optimization
Improved water use efficiency helps irrigation inputs work harder for your bottom line.
Real Results
Farmers using RainBox™ have reported significant improvements in soil health and crop yields. The system's unique R-AOP technology enhances water quality, leading to better irrigation efficiency and healthier plants.
RainBox™ has been successfully implemented in various regions, demonstrating its versatility and effectiveness in different soil, climate and crop types.
In a recent study, farmers observed no more standing water in the treated fields, indicating improved drainage and soil structure. The results were evident in the field, with crops thriving in previously challenging conditions.
Below you will see comparison images of Control and Treated fields, notice the standing water in the Control field and the lack of it in the Treated field.

What Independent Experts Are Saying
Independent Agronomists
It’s Not NPK — It’s Oxygen Deficiency
Leading agronomists — not affiliated with Agriwater — are raising the alarm on one of agriculture’s most overlooked yield limiters. Water and oxygen compete for the same soil pore space. When water wins, roots suffer within hours.
Research published as far back as 1984 confirms that waterlogged soil during early growth stages like V3 can permanently collapse yield potential by 100–200 bushels per acre — not because of nutrient deficiency, but because of oxygen starvation at the root zone.

Customer Success Stories
See how farmers worldwide are transforming their irrigation practices with Agriwater
It took 6–8 hours to increase the subsoil of my orchards under drippers to field capacity. The filter had to be cleaned once a week and the drippers twice a month due to blockages. After five months of RainBox treatment, it took only four hours to water the subsoil (350 mm). The filter and drippers are now only inspected every two months!
The impact was well beyond our expectations. We saw a significant increase in yield.
The plants grow faster and more vigorously than ever before thanks to RainBox™.
The installation of 3 RainBox Units contributed to an increased percentage of our butternut export. The butternuts were more uniform and the plants recovered significantly faster after very high temperatures.
For me it is important to always look for new technologies that can sustainably increase my profitability in the long term. The RainBox Unit is successful in achieving this.
