April 25th Solvang City Council Meeting. City of Solvang Solvang will invest another $10 million into its wastewater treatment plant, including tooling that could support future wastewater recycling, after the council voted unanimously Monday to support the least expensive of four potential options.’I’d rather do the minimum until we’re forced. I like Phase 2, and it’s a step in the right direction. I don’t want to go into debt and I don’t want to just feel good about using nonpotable water from a recycled source just because it makes me feel good,’ Councilman Robert Clarke said.
