(Sacramento, CA) — California’s Delta tunnels water project is moving forward. After downsizing the project last year to save money, Governor Gavin Newsom’s administration released a preliminary cost estimate for the project late last week. The project is estimated to cost nearly 16-billion for a single tunnel running beneath the estuary south of Sacramento. The state is pushing the project forward, but participating local water agencies and irrigation districts south of the Delta would pay for it.
