Systems and methods for backflow management

An end-to-end fluid management system for a building, comprising:

• a building comprising a fluid system defining a potable water inlet and a wastewater outlet;
• an inlet device coupled to control a flow of potable water through the potable water inlet;
• and
• an outlet device in communication with the inlet device, the outlet device, comprising:
• a housing comprising threads and defining an interior volume, the threads being engaged with corresponding threads of the wastewater outlet;
• a cover coupled to seal the interior volume, the cover comprising a bore;
• and
• an electronic processing device disposed within the interior volume;
• a fluid sensor disposed within the interior volume, in communication with the electronic processing device, and oriented to detect fluid properties through the bore;
• a wireless communication device disposed within the interior volume and in communication with the electronic processing device;
• and
• a memory device storing instructions that when executed by the electronic processing device result in:
• receiving data descriptive of a fluid property of wastewater in the wastewater outlet;
• identifying, by the electronic processing device and by a comparison of the data to stored rules, an occurrence of a backflow event;
• and
• automatically transmitting, by the wireless communication device, and in response to the identified backflow event occurrence, a shutoff command to the inlet device.
