CORPUS CHRISTI, Texas — Corpus Christi's City Council received an update Tuesday from the team who is working on the permit for a desalination plant.

The desalination plant staff reported that potential sites for the desal plant had been narrowed down from 22 to 4 -- two in Nueces County and two in San Patricio County.

The idea for Corpus Christi to construct its desal plant started during the drought that lasted from 2011 to 2013.

Due to the amount of time, it takes for permitting, City Council decided to start the process so that the city would be ready to decide to build sometime in 2019.

The plant would have a minimum capacity of 10 million gallons of drinkable water per day to a maximum of 36 million gallons per day.

Tuesday's update answered questions for new members and gave the council a timetable for the summer.

"The project is on schedule. We're making good progress. We're soon going to be able to present to you the sites in our recommendations. Also, I hope to have your input and considerations in the next step of the project," consultant Nikolay Boutchkov. 

There will be a council workshop to look at the final sites, and Boutchkov said they hope to present the final plans for council consideration in July.

If City Council decides to build the plant funding would come from water sales, Texas water board funds and local industry who are current water customers.
