"We have about 13.5 months left of water supply," stated the City Water Utilities Director, Ricky Dickson.
When the city of San Angelo's water supply drops to just 12 months, stage 3 drought restrictions will be put into place. In the meantime, as work continues on the new water treatment plant, workers will begin blending water piped 62 miles from the Hickory Aquifer to San Angelo. Water from Lake Ivie will be blended with the Hickory water beginning May 1st.
"We just want this opportunity to test the system, make sure everything works alright, and not stay on that water for a long time," Dickson said.
Currently, the city of San Angelo uses an estimated 10 to 11 million gallons of water a day. This test supply will put about 1 million gallons of water a day into the system.
"If we have to get on the Hickory at nine-million gallons a day-even with what we have left...," continued Dickson.
The blending ration will be nine parts San Angelo city water supply with one part Hickory water, which contains radium and iron. The ratio is within state and federal requirements for public drinking water.
"So, we're going to bring in one-million-gallons of Hickory water and probably blend it with nine or ten-million-gallons of the surface water," Dickson explained.
If the trial blending process is successful, city officials said the blending process could continue.
"If this drought continues, they're saying Ivie is going to be depleted - probably - in November and that just leaves us with what water we have left in Nasworthy and Twin Buttes," finished Dickson.
The blending process at the Surface Water Treatment Plant is set to last, at least, two weeks.
