The contentious Central Coast Blue recycled water project is set to move forward in a new form in Grover Beach — but the city won’t have any control over whether it ultimately gets approved. … Once completed, the project is intended to take wastewater from the Pismo Beach Wastewater Treatment facility, clean it, and inject that water back into the Northern Cities Management Area of the Santa Maria Groundwater Basin, which supplies the Five Cities with water. Despite Grover Beach withdrawing from the project, officials said some of the water treatment and then injection would still have to happen from a new facility within the city’s limits — a move that left some Grover Beach residents concerned.
