1. What is Underground Storage Tank Sizing?

Underground storage tank sizing is the process of determining the appropriate volume capacity for tanks that will be buried underground. Proper sizing ensures adequate storage capacity while considering space constraints, safety regulations, and operational requirements.

2. How Does the Calculator Work?

The calculator uses the basic tank sizing formula:

Where:

• \( V \) — Required tank volume (m³)
• \( \text{demand} \) — Daily consumption or requirement (m³/day)
• \( \text{days} \) — Number of days of storage needed

Explanation: This formula calculates the minimum tank volume needed to meet demand over a specified period without replenishment.

3. Importance of Proper Tank Sizing

Details: Correct tank sizing is crucial for ensuring adequate supply, preventing overflow or shortages, complying with regulations, and optimizing installation and maintenance costs.

4. Using the Calculator

Tips: Enter the daily demand in cubic meters per day and the number of days of storage required. Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What factors should be considered beyond basic calculation?
A: Safety factors, peak demand periods, refill schedules, regulatory requirements, and potential future expansion should all be considered.

Q2: How does tank shape affect capacity calculations?
A: While volume is the primary concern, tank shape affects installation feasibility, structural integrity, and may require additional calculations for irregular shapes.

Q3: What are common materials for underground tanks?
A: Common materials include fiberglass, steel with corrosion protection, and polyethylene, each with different durability and cost considerations.

Q4: Are there regulatory requirements for underground tanks?
A: Yes, most jurisdictions have specific regulations regarding underground tank installation, including leak detection, secondary containment, and monitoring requirements.

Q5: Should safety factors be added to the calculated volume?
A: Typically, a safety factor of 10-20% is added to account for unexpected demand increases or delayed refills.
