Dependable water storage is essential for electronics and semiconductor campuses. Semiconductor fabs, electronics assembly facilities, and R&D laboratories require reliable continuous water supply for essential applications such as wafer cleaning, cooling systems, and development laboratories and even non-essential applications like toilets, landscaping, and cleaning. 

RCC (Reinforced Cement Concrete) tanks provide the most feasible and durable option for water storage in an industrial setting. By optimizing tank capacity, material selection, and level of design, deeper levels of operational performance can be obtained, and ultimately downtime and maintenance costs can be minimized.

Varuna RCC tank solutions excel in the engineering and delivery of premium tanks for industrial facilities; combining the best of engineering expertise along with sustainable practices, Varuna assists electronics and semiconductor campuses in maximizing their water efficiencies, maintaining reliability, and ensuring lasting savings under their water solutions.

Understanding Water Needs in Electronics & Semiconductor Facilities

Daily Water Consumption Patterns

Semiconductor and electronic campuses can have daily demands of the order of gallons and the types of water usage consist of:

•  Process water for fabrication and testing and cleaning
•  Cooling water for HVAC and cooling equipment
•  Laboratory and R&D
•  Non-critical consumptive uses - toilets, landscaping, cleaning

If you need to work to determine sufficient and appropriate sizing of the RCC tanks, you will want to understand usage patterns.  Underestimating will lead to potential water shortages, and overestimating will lead to unnecessary construction and cost.

Non-Critical vs Critical Water Uses

• Critical uses: Require high-purity water for cleanroom operations, labs, and production processes.
• Non-critical uses: Can utilize treated or recycled water from STP/ETP systems for toilets, irrigation, and cleaning.

Varuna RCC tank solutions are designed to integrate seamlessly with water recycling systems, enabling campuses to reuse treated water for non-critical applications efficiently.

Role of Varuna in Efficient Water Storage Planning

Varuna provides:

• Assessment of daily and peak water demands
• Recommendations for tank types (overhead or underground) and capacities
• Integration with STP/ETP systems for water recycling
• Modular designs for future expansion

This ensures customized water storage solutions tailored to each campus’s unique needs.

Optimizing RCC Tank Capacity

Calculating Water Demand for Industrial Campuses

Accurate tank sizing involves:

1. Estimating daily water usage per building or process
2. Accounting for peak demand and buffer storage
3. Incorporating recycled water from STP/ETP systems

Buffer storage ensures uninterrupted supply for critical operations like cleanrooms, cooling, and laboratory processes.

Notes: Capacities include buffer storage to handle peak demand. Varuna ensures all tanks meet industrial pressure and chemical resistance standards.

Factors Affecting RCC Tank Sizing

• Peak vs average demand: Prevents overloading tanks during surges
• Number of users and processes: More facilities require larger capacity
• Integration with STP/ETP systems: Recycled water reduces total freshwater storage requirements
• Site constraints: Determines whether overhead or underground placement is feasible

Varuna’s Approach to Capacity Optimization

Varuna uses data-driven planning to optimize tank capacity:

• Designs customized solutions based on actual facility water demand
• Integrates with STP/ETP systems for water recycling
• Ensures regulatory compliance and operational efficiency

Choosing the Right RCC Tank Material

Material Properties for Durability

RCC tanks must withstand:

• Water pressure and structural loads
• Corrosion from chemicals in industrial water
• Environmental exposure and temperature variations

Varuna ensures the use of high-strength reinforced concrete and corrosion-resistant additives to guarantee long-term performance.

Overhead vs Underground RCC Tanks

Overhead Tanks:

• Provide gravity-fed water supply
• Ideal for toilets, landscaping, and cleaning
• Easier to monitor and maintain

Underground Tanks:

• Save surface space
• Protect water from contamination
• Minimize evaporation and thermal effects
