Water Service Update
Posted: Nov 29, 2022 3:23pm

Cimarron Municipal Utility District does not receive water from the City of Houston. Water provided by the District is safe to drink and is not affected by the City's boil water notice. Any official notices about changes in the District's water system will come directly from the District and the District's operator, Si Environmental.

Welcome to Cimarron MUD

Created on February 9, 1976, Cimarron Municipal Utility District has been providing water and waste-water services for over 40 years. We are currently transitioning from reliance on ground water aquifiers over to surface water. In an effort to reduce subsidence this conversion to surface water has been mandated by the West Harris County Regional Water Authority, founded in 2001.
