Smart building water supply management system with leak detection and flood prevention

A system for distribution of a fluid to a structure comprising:

• a logic-based electronic control module
• an electrically-actuated valve having a normally closed state and connected, upstream, to a main fluid supply and, downstream, to a distribution system for the structure
• a sealed accumulator tank connected downstream to said electrically actuated valve, said tank being partially filled with said fluid
• a pressure sensor connected to said tank,
• said electronic control module being in communication with the pressure sensor and the electrically actuated valve;
• the electronic control module programmed to:
• determine, based on input from said pressure sensor, a flow rate of the fluid to the distribution system for the structure
• determine whether said flow rate of the fluid represents an acceptable fluid demand condition;
• cause the electrically actuated valve to open if said determination of an acceptable fluid demand condition is positive
• wherein;
• said fluid is water;
• and
• said accumulator tank further comprises a flexible member separating a water-filled region from an air-filled region.
