City of San Angelo

WHERE DOES OUR WATER COME FROM? San Angelo currently has six-floor water sources: Twin Buttes Reservoir, O.C. Fisher Lake, Lake Nasworthy, O.H. Ivie Reservoir, E.V. Spence Reservoir, and the South Concho River. San Angelo presently receives its source water from O.H. Ivie Reservoir or the South Concho River, which is fed by Twin Buttes and Lake Nasworthy. O.H. Ivie Reservoir is usually the number one supplier. However, every so often the South Concho River is used because of the primary source. Occasionally, the 2 source glasses of water are mixed. In 2014, the Hickory Aquifer groundwater became available as a further water source. A water treatment plant, which includes ion change and pressure filtration to put off radium and iron from the Hickory groundwater, has been finished and is presently being used as a further water supply. The dealt with groundwater is mixed with surface water. Hickory water wells have a mean 18 pCi/L of radium. The groundwater remedy plant will take away approximately 90-ninety five percent of the radium resulting in approximately 1 pCi/L in the completed water. This water is then combined with surface water, to lessen the radium content material even more, most probable beneath 1 pCi/L. The TCEQ regulatory limit is presently five pCi/L. The Hickory Aquifer water additionally has miles decrease mineral and natural content than the metropolis’s floor water assets. Utilizing this water will result in a decrease in ordinary overall mineral content of the finished water. The lower tiers of natural cloth within the water will also help reduce the formation of trihalomethanes (THMs) throughout the disinfection technique.

CHLORAMINE DISINFECTION San Angelo uses an aggregate of chlorine gas and liquid ammonium sulfate for disinfection. When combined, chloramine is formed. Chloramine is in most cases composed of monochloramine, with a lot lesser tiers of dichloramine and trichloramine. Surface water sources, along with O.H. Ivie and the South Concho River, normally contain dissolved natural compounds that react with unfastened chlorine at some stage in disinfection to shape undesirable byproducts known as trihalomethanes (THMs). To lessen the manufacturing of THMs, liquid ammonium sulfate is introduced on the time of chlorination so it will combine with the chlorine to form chloramines. This is finished particularly to lessen and manage the production of THMs. As chloramine movements through the distribution system and provides disinfection of the water, it in part decays and releases ammonia. Over time, the ammonia can cause unwanted aspect-outcomes which include nitrification and biofilm. Periodically the disinfectant should be changed again from chloramines to free chlorine to he.
