The Horizon area has one of the most reliable water supplies in the arid Southwest thanks to an abundant aquifer. HRMUD, with its three R.O. train systems, is able to turn the brackish groundwater reserve into approximately eight million gallons per day of quality water to customers.  The Texas Commission on Environmental Quality district rates HRMUD a Superior Water System.

REVERSE
OSMOSIS
Reverse Osmosis is a membrane separation process in which raw water flows along the membrane surface under pressure. Purified water permeates the membrane and is collected. The waste that does not flow through the membrane is discharged to the district’s evaporation ponds. The ponds are lined with clay, preventing salty water from percolating back into the aquifer. Reverse osmosis systems remove up to 99 percent of all dissolved minerals, microorganisms, particles and many high molecular weight organics. Reverse osmosis has proven to be most efficient for removing salts, chemical contaminants, and heavy metal, such as lead, from water.
