East County is moving closer to building a new wastewater treatment plant to recycle millions of gallons a day, amid a severe lack of rainfall that’s pushed the region into its driest period in a millennium.

Officials with the local Helix Water District have announced they and other project leaders are more than halfway done designing a system to make the region less reliant on outside water. The governing body overseeing the project is scheduled to vote May 19 on a final price with contractors, a spokeswoman said.
