Water Supply Methods - INI

Water supply methods are classifications of systems for supplying tap water to buildings. They are broadly divided into two types: 'direct connection water supply' and 'reservoir tank system (storage tank water supply)', each with multiple variations. Direct connection systems supply water directly from the main water pipe and include direct pressure and booster types. Reservoir tank systems store water in a receiving tank before distribution and include elevated tank and pressure tank types. The appropriate method is selected based on building height, purpose, and hygiene management requirements.
