Tehachapi’s planned indirect potable reuse project collapses after Watermaster withdraws support and CEQA objections

A multi‑year plan in Tehachapi to treat and recharge wastewater into the local aquifer — a technique known as indirect potable reuse (IPR) — collapsed after the county Watermaster stopped honoring a memorandum of understanding and the local water district raised environmental objections under the California Environmental Quality Act (CEQA), according to a local reporting series.

City planners and engineers argued the IPR system would have taken roughly 700–750 acre‑feet a year of treated wastewater — about one‑third of the city’s roughly 2,000 acre‑feet annual consumption — and by cleaning and recharging that water could have added the equivalent of that volume to the local supply. "So it would instantly add 30% of the city's water supply over again," Narrator 2 said in the episode, adding that the system could be banked underground and extend the city's supply by decades.

Supporters framed IPR as a sustainability measure that would make the city less reliant on imported State Water Project (SWP) allocations, protect agricultural users who currently rely on SWP water, and create a locally controlled, drought‑resistant source. The project’s proponents included engineering staff and consultants and, according to the episode, former development services director Jay Schlosser and public works director Don Marsh were involved in planning.

But the episode says negotiations with the Watermaster proved decisive. After a prolonged, lawyer‑assisted negotiation the city and the Watermaster signed an MOU intended to clarify the regulator’s role and assure the Watermaster that the basin would be protected. "We signed that MOU. And without exaggeration, I say that within 3 months, we began receiving emails from the water master that he no longer wished to honor that agreement," Narrator 2 said.

When the CEQA review began, the water district submitted written objections centered on "safe yield," the calculation of how much groundwater can be sustainably extracted each year. The district disputed counting the full recycled volume as new, saying some portion historically returned to the aquifer and therefore should not be considered available consumptive supply. The district, as described in the episode, pushed back that much of the historically returned water must remain in the ground — reducing the city’s usable benefit from roughly 700 acre‑feet to about 200 acre‑feet.

Narrators in the episode described tracking exactly how much water returns to the aquifer as difficult because of factors such as rainfall, vegetation, runoff and soil absorption, and they said the city expected that these questions would be addressed during the MOU negotiations rather than raised after the agreement was signed. "CEQA permits you to challenge the adequacy of that process from frankly a not very honest position," Narrator 2 said, arguing CEQA can be used to halt projects by litigating environmental review.

Faced with a sharply reduced project benefit, the episode says the IPR plan "wasn't cost efficient" and a decade of planning collapsed; the dispute strained relations between the city and the water district and resulted in a lawsuit. The city, according to the episode, remains dependent on native groundwater and on supplemental SWP water it is contractually entitled to buy but unable to access.

No formal vote or city council action is reported in the episode; the account is framed as a retrospective narrative based on interviews and planning documents discussed in the series. The episode closes by saying the next installment will explore why the water district’s decisions appear to correspond with particular financial interests at the agency.

The reporting series characterizes the project’s failure as the result of a breakdown in collaboration between the city, the Watermaster and the water district, an accounting dispute over safe yield, and the practical financial calculation that left the project unable to proceed.
