FAQs for Rio Grande
Who provides tap water in Rio Grande, TX?
The primary municipal system highlighted here is CITY OF RIO GRANDE CITY (PWSID TX2140018). Rio Grande may also have nearby MUDs, districts, or supply corporations; your bill or CCR names the system that serves your address.
How do I read health-based violations?
Health-based violations involve MCL, MRDL, or treatment technique issues. A past violation does not automatically mean current water is unsafe—check status, dates, and your utility’s public notices/CCR.

Some systems buy water from wholesalers. Your retail utility is still responsible for delivering finished water and issuing the CCR for customers.
Where can I get official documents?
Search your utility name + “Consumer Confidence Report”, check Texas Commission on Environmental Quality (TCEQ) drinking water resources, and use EPA’s ECHO detailed facility report links on each utility page.
