1. What is the Indian Standard Water Tank Formula?

The Indian Standard IS 3370 provides guidelines for water tank capacity calculation. The formula estimates the required water storage capacity based on daily demand and retention period, ensuring adequate water supply for residential and commercial buildings.

2. How Does the Calculator Work?

The calculator uses the Indian standard formula:

\[ Volume = Demand \times Retention \times 1000 \]

Where:

\( Demand \) — Daily water requirement in liters/day
\( Retention \) — Number of days water needs to be stored
\( 1000 \) — Conversion factor to liters

Explanation: The formula calculates the total water storage capacity needed to meet the daily demand for the specified retention period.

3. Importance of Water Tank Capacity Calculation

Details: Proper water tank sizing is essential for ensuring continuous water supply, managing water resources efficiently, and complying with building codes and standards in India.

4. Using the Calculator

Tips: Enter daily water demand in liters/day and retention period in days. Both values must be positive numbers to get accurate results.

5. Frequently Asked Questions (FAQ)

Q1: What is the basis of IS 3370 standard?
A: IS 3370 provides guidelines for concrete structures for water storage, including capacity calculation methods based on demand and retention requirements.

Q2: How to determine daily water demand?
A: Daily demand depends on number of occupants, usage patterns, and local water supply conditions. Typical values range from 135-225 liters per person per day.

Q3: What is an appropriate retention period?
A: Retention period typically ranges from 1-3 days, depending on water supply reliability and local regulations.

Q4: Does this account for emergency storage?
A: The basic formula provides regular storage capacity. Additional capacity for fire fighting or emergencies should be added separately as per local requirements.

Q5: Are there different formulas for different building types?
A: While the basic formula remains the same, demand values vary for residential, commercial, industrial, and institutional buildings as per Indian standards.
