Design Guidelines
For domestic dwellings, the recommended minimum water storage capacity is 200 – 300 liters (53 – 79 gallons). This ensures adequate supply for typical household demand over a 24-hour period.
Note: Actual storage requirements depend on occupancy levels, fixture count, and peak demand patterns. Refer to CIBSE Guide G (2004) Public Health Engineering for detailed sizing methodology.
