1. What is Underground Tank Design Calculation?

The Underground Tank Design Calculation determines the required volume of an underground storage tank based on water demand, retention period, and safety factor considerations for various applications.

2. How Does the Calculator Work?

The calculator uses the underground tank design formula:

\[ V = \text{demand} \times \text{retention} + \text{safety} \]

Where:

\( V \) — Design volume (m³)
\( \text{demand} \) — Daily water demand (m³/day)
\( \text{retention} \) — Required retention period (days)
\( \text{safety} \) — Additional safety factor (m³)

Explanation: The formula calculates the minimum tank volume needed to meet water demand requirements while accounting for storage duration and providing an additional safety margin.

3. Importance of Tank Volume Calculation

Details: Proper tank sizing is crucial for ensuring adequate water supply, optimizing system performance, preventing overflow or shortage situations, and meeting regulatory requirements for various applications.

4. Using the Calculator

Tips: Enter daily water demand in m³/day, required retention period in days, and safety factor in m³. All values must be positive numbers to calculate the appropriate tank volume.

5. Frequently Asked Questions (FAQ)

Q1: What factors influence the demand value?
A: Demand depends on population served, usage patterns, seasonal variations, and specific application requirements such as fire protection or irrigation needs.

Q2: How is the retention period determined?
A: Retention period is based on usage requirements, refill frequency, emergency backup needs, and regulatory standards for different types of storage systems.

Q3: What does the safety factor account for?
A: The safety factor provides additional capacity for unexpected demand increases, evaporation losses, sediment accumulation, and future expansion requirements.

Q4: Are there standard safety factor values?
A: Safety factors typically range from 10-20% of the calculated volume, but may vary based on specific project requirements, risk assessment, and local regulations.

Q5: Can this calculation be used for different tank types?
A: While the basic formula applies to various underground tanks, specific applications may require additional considerations for shape, depth, and material specifications.
