From New California Law Allows San Diego to Revive Water Conservation Discounts

How could the new state law affect the San Diego County Water Authority's rate structure?

Possible What happens if… A possibility worth considering, not a forecast.

New state law may help San Diego County Water Authority revive conservation discounts. The new state law, AB 2180, signed by Governor Gavin Newsom, changes the legal requirements for water agencies to set tiered rates. Previously, a court ruling forced San Diego to switch from tiered rates to uniform rates by January 1 to comply with the ruling in Patz v. City of San Diego. AB 2180 allows agencies to justify tiered rates based on ordinary customer characteristics, such as property size or peak-demand estimates, rather than requiring precise cost measurements. This provides a path for the San Diego County Water Authority to potentially resume conservation discounts in 2028 or 2029.

The facts so far

As reported. Each one links to where it comes from.

Why it matters

Water conservation is a critical issue for San Diego County, and the ability of water agencies to incentivize low-volume usage through discounts is key to managing resources. The previous court ruling cast doubt on the rate structures of nearly every water agency in California, forcing a shift to uniform rates that changed how the 14% overall hike was distributed among customer classes.

This legislative shift provides a clearer, lower-risk path back to conservation-based pricing for the San Diego County Water Authority. However, the Authority must first complete the transition to uniform rates before it can attempt to revive tiered rates under the new legal framework.

What we don't know yet

  • Will the San Diego City Council adopt AB 2180 to allow the Authority to resume tiered rates?
  • What specific timeline will the San Diego County Water Authority follow to implement the new legal standard?
