Commercial RO Plant Installed at ACC RMC Plant to Improve Concrete Quality and Water Efficiency: A Case Study by Netsol Water
Water plays a crucial role in the production of high-quality concrete. In Ready Mix Concrete (RMC) plants, the quality of water used for batching and mixing directly impacts the strength, durability, and performance of the concrete produced. Impurities such as high Total Dissolved Solids (TDS), hardness, chlorides and suspended particles can negatively affect the hydration process of cement and ultimately compromise the structural integrity of concrete.
Construction companies and cement manufacturers are therefore increasingly focusing on maintaining strict water quality standards in their RMC operations. One of the most effective solutions to ensure consistent water quality is the installation of Commercial RO plants, which remove dissolved salts and contaminants from raw water sources such as borewell water.
Recognizing the importance of reliable water treatment for its operations, ACC Limited, one of India's leading cement and concrete companies, implemented a high-performance 3000 LPH Commercial RO Plant at its Ready Mix Concrete (RMC) plant in Greater Noida.
The system was designed, manufactured, and installed by Netsol Water, a leading water and wastewater treatment company specializing in industrial RO plants, sewage treatment plants and water treatment solutions.
This case study highlights the challenges faced at the RMC plant, the design and installation of the RO plant, and the significant improvements achieved in water quality, operational efficiency, and sustainability.

Project Overview
To improve water quality for concrete production at its Greater Noida facility, ACC decided to install a 3000 LPH Commercial RO Plant.
Project Details
| Parameter | Details |
| Client | ACC Limited |
| Location | Greater Noida, Uttar Pradesh |
| Application | Ready Mix Concrete Plant |
| RO Plant Capacity | 3000 LPH |
| Technology | Reverse Osmosis |
| Installed By | Netsol Water |
| Raw Water Source | Borewell Water |
The primary objective of installing the RO plant was to remove excess dissolved salts and impurities from raw water and ensure that only treated water meeting acceptable quality standards is used in concrete production.
Challenges Faced by the RMC Plant
Before installing the RO plant, the RMC facility was using groundwater sourced from borewells for its operations. However, the water quality analysis revealed several issues.
Key Challenges
1: High TDS Levels
Groundwater in many parts of the Delhi NCR region contains high levels of dissolved salts. The raw water at the site had TDS levels exceeding 2000 ppm, which could negatively impact concrete quality.
2: Hardness and Mineral Content
Excessive hardness caused scaling in pipelines, valves, and batching equipment, increasing maintenance requirements.
3: Chlorides and Sulphates
High concentrations of chlorides and sulphates can affect the corrosion resistance of reinforced concrete structures.
4: Equipment Scaling
Mineral deposits inside pipelines and mixers resulted in reduced efficiency and higher maintenance costs.
5: Water Quality Inconsistency
Seasonal variations in groundwater quality made it difficult to maintain uniform water quality for concrete production.
These challenges prompted ACC to install a reliable and efficient water treatment solution.
Importance of Water Quality in Ready Mix Concrete
Water used in concrete mixing must meet specific quality standards to ensure optimal performance.
Poor water quality can result in:
. Reduced compressive strength of concrete
. Delayed or irregular cement hydration
. Corrosion of reinforcement steel
. Poor durability of concrete structures
. Reduced workability of concrete
Therefore, RMC plants must use treated water that meets established construction standards.
Water Quality Standards for Concrete Production
In India, water used for construction must comply with the guidelines specified in IS 456:2000 – Plain and Reinforced Concrete Code of Practice.
Recommended Water Quality Parameters
| Parameter | Raw Water | Treated Water |
|---|---|---|
| TDS | 2200 ppm | < 100 ppm |
| Hardness | High | Low |
| Suspended Solids | Moderate | Negligible |
| Chlorides | High | Controlled |
The installation of the RO plant ensured that treated water supplied to the batching process remained within the recommended limits.

The membranes remove:
. Dissolved salts
. Heavy metals
. Chlorides
. Sulphates
. Hardness
Step 6: Treated Water Storage
The purified water is stored in a treated water tank and supplied to the RMC batching process.
Raw Water vs Treated Water Quality
The installation of the RO plant significantly improved water quality.
| Parameter | Raw Water | Treated Water |
