Full Breakdown
Reclaimed (purple-pipe) water in Frisco is delivered through NTMWD and city infrastructure to qualifying parks, golf courses, and large commercial sites for irrigation and cooling. Connection requires a cross-connection control device, dedicated piping, and purple-pipe identification under Texas Commission on Environmental Quality rules. Reclaimed water cannot be used for drinking, food prep, swimming pools, or interior plumbing. Sites must post non-potable warning signs at all hose bibs and quick-connects. Single-family residential reclaimed connections are not generally available in Frisco.
Violations & Fines
Cross-connections to potable systems, missing signage, or unauthorized use can trigger TCEQ enforcement, fines, and immediate disconnection by the City.
