Water restrictions in Collin County, TX — also called the watering schedule, outdoor irrigation rules, or drought ordinance — set which days and hours you can run sprinklers or irrigation.
Collin County is served primarily by North Texas Municipal Water District (NTMWD) which enforces year-round twice-per-week watering limits across member cities and unincorporated areas receiving NTMWD water. No watering 10am-6pm April-October. Stage 1 drought restrictions are the baseline; Stage 2-4 tighten further.
NTMWD serves 2 million people including most Collin County cities (Plano, McKinney, Frisco, Allen, Wylie, Princeton, Prosper, Rockwall). Standard rules: automatic irrigation twice weekly on assigned days based on address; handheld hose with nozzle allowed any time; no irrigation 10am-6pm April 1-October 31; no water runoff onto paved surfaces. Rain/freeze sensors required on automatic systems since 2009 (TX HB 1656). Drought Stage 2 drops to once-weekly; Stage 3-4 may ban outdoor watering entirely.
First warning, then escalating citations by city: typically 150 first offense, 300-500 subsequent. NTMWD may fine water utilities for exceeding allocations.
