The Unaccounted Litre

Sera Venn liked numbers that closed.

The Exchange main did not close. Every morning the overnight balance was short by a volume that would have been a scandal if it had arrived as a fountain in the square and was, instead, a rounding error with stamina.

“Seasonal,” said her supervisor, who had three years left and a plant on his desk that was doing better than the pipes.

“It’s the same in every season.”

“Then it’s a model error.”

Sera opened Civic Network. Approved Public Gateway offered her seven verified explanations, all of which had the word leakage and none of which had a hole.

She walked.

Central Exchange at 09:10 was already performing civic life: kiosk, fountain (working, which still surprised her), a child being told not to treat the rim as a boat. Pell from Maintenance was sitting on that rim with a sandwich, as if the water were a colleague on a break.

“You’re Water,” he said.

“You’re the pump.”

“The pump is under the plant. I’m only the apology.”

She showed him the overnight short.

Pell chewed.

“That’s not a burst,” he said. “Bursts arrive with shouting and a smell. That’s a conversation the main is having with a relative it doesn’t claim.”

“Meaning.”

“Meaning a line that used to be Foundry service. Blanked. Not dead.”

Sera had been trained to call that theft.

Pell wiped his hands on his trousers.

“If you map it as a success, they shut it. If you leave it as a fault, someone else will map it. If you call it unaccounted, the plant on your supervisor’s desk keeps growing.”

“That’s not a procedure.”

“It’s how the city drinks in two directions.”

She filed an interim: Volume unaccounted. No surface burst located. Recommend continued observation. Do not raise a heritage photograph of any associated board.

Her supervisor read it.

“Observation of what?”

“Of the fact that the litre is going somewhere people already live.”

He looked tired in a municipal way.

“Don’t put living in the log.”

“Then it stays unaccounted.”

“Good.”

Sera went back to the wall of numbers.

The short was there again, faithful as a tide.

She added a private note to a paper book that Civic Network could not search:

The city meters what it can see. I have seen the gap. I will not make it a map.

Pell, later, sent a message that said only The plant is still in front of the board.

She sent back Keep it there.

The fountain threw a clean arc into the basin.

Somewhere under the Exchange, a valve that was not on her screen opened because a woman Sera would never be allowed to name had decided it was morning.

The litre left.

The balance did not close.

Sera, against her training, was almost grateful.
