Usable Tank Capacity Equation
V_{usable} = L times W times (H_{total} - H_{freeboard}) times 1000 text{ Liters}; quad text{Autonomy} = frac{V_{usable}}{text{Occupants} times 135}
Engineering Specifications & Method of Calculation
Determine storage capacities for underground sumps, overhead RCC reservoirs, and cylindrical water tanks with building population demand analysis.
Domestic Water Storage Standards
Standard municipal water demand averages 135 Liters Per Capita per Day (LPCD) for residential dwellings. A minimum 300mm freeboard is required between water top level and roof slab.
Frequently Asked Questions
What is the purpose of freeboard in a water tank?
Freeboard provides air space for float valve operation, overflow relief, and ventilation to prevent contamination and water hammer surges.
