Grifo Water
Every hydrant is an open tap. Grifo closes the loop.
A self-powered authorization valve for contractor hydrant draws. Water flows only after a credentialed handshake, every gallon is metered, and the invoice lands in your existing utility billing system — automatically.
How it works
Contractor taps their phone — NFC powers an offline credential handshake. The clutch engages the free-spinning nut, the turbine meters every gallon while powering the device, and the invoice lands in Tyler.
Fire flow is never touched
Only the 2.5″ auxiliary port is fitted. The 4.5″ steamer is unmodified, override is mechanical, and deployment is limited to contractor hydrants chosen with the fire marshal.
Fail-secure by physics
The nut free-spins at rest — electronics are the only thing that can engage it. Smashing the device doesn't release water; it bricks the auxiliary valve. Vandalism is worse than compliance.
No new dashboard
Billing in Tyler, draw maps in Esri ArcGIS, tamper work orders in Cityworks. Your staff work in the systems they already use.
The device that pays the city — instead of costing it.
Pilot: 20–30 hydrants, one corridor · <10 hrs total staff time · day-90 readout in dollars · revenue-share — costs the city nothing.
