Plano uses NTMWD-treated reclaimed water to irrigate select parks, golf courses, and medians, reducing potable demand on Lake Lavon. Private connections require a TCEQ-permitted reuse plan and dedicated purple-pipe infrastructure.
The North Texas Municipal Water District operates Texas Commission on Environmental Quality permitted Type I reuse facilities that supply Plano with reclaimed water for non-potable irrigation. Pecan Hollow Golf Course and several large median strips draw on the system through purple-pipe distribution. Private commercial users wishing to tap reuse must hold a TCEQ Chapter 210 authorization and install backflow prevention assemblies. Cross-connections between potable and reuse lines are strictly forbidden. Signage labeling reclaimed water as non-potable is mandatory at every point of use.
Cross-connecting reuse and potable supply, drinking from reuse spigots, or operating a reuse system without TCEQ Chapter 210 authorization can result in immediate disconnection and TCEQ enforcement penalties.
