24 HOURS · THE EAST BAY

Who actually owns the water in my city?

Five water agencies serve the East Bay, and calling your water company is not an instruction anybody here can follow. EBMUD runs the core. Fremont, Newark and Union City do not. The Tri-Valley and the east end each answer somewhere else.

Who runs the core?

EBMUD, across Oakland, Berkeley and most of the inner cities.

It is the one people assume covers everything, and it does not.

The line moves when you cross into the south county or out east.

Who runs the south county?

Alameda County Water District in Fremont, Newark and Union City.

Three cities, one district, and none of them answers to the core agency.

Fremont and Newark each have a page of their own here. So does Union City.

What about Hayward?

It buys its water wholesale rather than pumping its own.

One city, its own arrangement, and a different number to call.

Hayward sits between two other systems and belongs to neither.

Who serves the Tri-Valley?

Zone 7 wholesale, with four retailers underneath it.

So there are two layers out there, and the one that answers your phone is the retailer.

Pleasanton and Dublin sit inside that arrangement. So does Livermore.

Wholesale and retail answering different questions is the part that confuses people.

And the east end?

Contra Costa Water District, where retail and wholesale split again.

Out past Concord the same two-layer problem repeats, with different names on it.

Which is why a page like this refuses to write call your water company.

It is not an instruction. It is a shrug with a verb in it.

Why does any of this matter?

Because a running leak is somebody’s job, and rarely ours.

A pipe still running is a plumber’s problem, or the agency’s. It depends on which side of the meter it sits.

We dry what the water already ruined. We do not stop the water.

Saying so early saves people an hour and sometimes a visit.

How do I find my meter?

In a lidded box near the curb, usually at the front.

Lift the lid with a screwdriver rather than your fingers. Those boxes are dark, damp and popular with spiders.

Find the small dial that spins on the least movement.

Shut every tap in the house. A dial still turning says water is going somewhere.

Does that find the leak?

No. It proves one exists and narrows the field.

Nothing about a spinning dial tells you where, and nobody should open a floor on that alone.

It is still worth an hour, because it turns a suspicion into a fact.

Hand that fact to whoever has the equipment to locate it.

And once it is wet?

Then it is ours, and the meters set the schedule.

Drying starts at $61 an hour and runs until the readings agree.

All four figures sit on one rate card.

Coming out to read the walls costs nothing, whoever turns out to own the pipe.

An East Bay address raises plenty more, and the guides hold it.

Sixty-six years separate the median house in two East Bay cities. One sits inside the sampling window and one does not, and that decides day one.

Castro Valley Is Not a City: Permits Change

Castro Valley is unincorporated Alameda County. No city hall, county permits, its own sanitary district. What that changes about closing a wall there.

The Hayward Fault and Closing a Wall, East Bay

The fault runs under seven East Bay cities. It changes nothing about drying and a great deal about what it takes to close a wall again.

Whoever turns out to own that pipe, reading the walls costs nothing. (341) 220-0032, and somebody drives out.
