The Water Bill That Tripled While I Watched the Meter at Dawn

A man who trusts a number

I taught mathematics for thirty-eight years, most of them at a high school in the east of Pretoria, and the one thing I told every class on their first day was that a number does not lie to you. People lie. Numbers simply are. So when my water bill arrived in the autumn of last year and the figure at the bottom was almost three times what it had been in January, I did not panic the way my daughter assumed I would. I sat down at the kitchen table, I put on my reading glasses, and I decided that somewhere in the arithmetic there was an honest answer waiting for a patient man.

I should tell you that I live alone now. My wife, Marietjie, passed four years ago, and the house is too big and too quiet, and I have filled the quiet with routines. I read the newspaper front to back. I walk to the shop even when I do not need anything. And now, it seemed, I had a new project, the kind of project a retired man secretly longs for: something with a cause and an effect, something I could solve.

The first month I assumed it was a mistake at the municipality. I have never fully trusted them, if I am honest, not since they estimated my readings for a whole winter and then sent me a correction that made no sense. So I phoned, I waited the usual eternity of hold music, and a tired young woman told me the reading was actual, not estimated, and that perhaps I had a leak. A leak. I looked out of the window at my dry, ordinary garden and I nearly laughed. There was no puddle. No damp patch. No sound of running water anywhere in the house. Where, I asked her, is this invisible leak of yours?

Taping the taps at midnight

Now, a scientist tests. That is the whole of it. So I became, at the age of sixty-eight, a man who tested his own plumbing with the seriousness of a lab technician.

I started with the taps. Every tap in the house, inside and out, I wrapped the spout in a square of kitchen paper and a strip of masking tape, and I checked each one at the end of the day for the faintest grey of moisture. Nothing. The toilets I tested the old way, a few drops of food colouring in the cistern, left overnight, to see if colour crept into the bowl. Marietjie would have scolded me for the blue stains I left on the porcelain, but she also would have understood. She knew what I was like with a problem. She used to say I would rather miss supper than leave a sum half done.

Then I found the stopcock, the main valve where the municipal supply enters the property, and this is where a teacher's habit of recording everything took over my life for a while. I would close every tap in the house, make sure the geyser was not filling, and then go out in the dark to the meter by the gate and watch the little red dial. If the house was truly sealed and the dial still turned, then water was leaving the system somewhere I could not see. And the dial turned. Slowly, patiently, like a clock that would not be argued with, it turned.

The dead-of-night readings

This is the part my daughter still teases me about. For the better part of three weeks I set my alarm for half past four in the morning, pulled my dressing gown over my pyjamas, pushed my feet into Marietjie's old garden clogs because they were by the door, and walked down the driveway with a torch and a notebook to read the meter before the city woke and before anyone in the neighbourhood could possibly be using water. Four thirty. Five thirty. A reading at each, written in my small square handwriting, the difference calculated on the spot in the margin.

The figures were brutally consistent. Litre after litre, hour after hour, even when the whole suburb should have been asleep and every tap in my house was shut. I filled page after page. I drew a graph. I am not ashamed to say I drew a graph of my own water loss by candlelight, and that there was a strange comfort in it, the comfort of a man who has found something solid to hold on to in a house that had felt unmoored for years. The leak, whatever it was, had given me a reason to be awake, and a reason to care about tomorrow's reading.

Somewhere in that fortnight I started reading everything I could find about how these things are even located, and I came across the idea of leak detection as a proper discipline, a thing with method and instruments, not just a plumber poking about with a spanner. That appealed to the teacher in me enormously. The notion that you could find water you could not see, by listening rather than digging, struck me as almost elegant.

Marietjie's roses, and the thing I got wrong

Here is where I must confess my one great error, the one that still makes me wince.

Along the north wall of the garden are Marietjie's roses. She planted them the year we moved in, and after she died I kept them alive out of something between duty and love, mostly love, I think, though I would not have said so out loud. And that autumn the roses were magnificent. Absurdly, impossibly magnificent, blooming out of season, greener and fuller than they had any right to be, while the lawn around them had gone soft and spongy underfoot in a way I had decided was simply the shade.

For weeks I told myself the roses were thriving because I was finally watering them properly. I even felt a quiet pride about it, as though Marietjie could see that I had not let her garden go. It did not once occur to me, stubborn old fool that I am, that the roses and the soft lawn and the turning meter were the same story. The water was not a kindness I was doing the garden. It was the leak, feeding the roots from below, drowning the grass, pushing those roses up out of the ground on a hidden spring. My wife's favourite flowers were blooming on the back of a burst pipe, and I had taken the credit.

When the man finally explained it to me, standing on my lawn with his equipment, I had to turn away for a moment and pretend to study the fence.

Listening to the ground

I had expected, I think, that finding the leak would mean men with picks tearing my garden to pieces, trenches everywhere, the whole yard turned into a building site for a month. That was the image that had stopped me calling anyone for too long. Instead a calm fellow arrived with what looked like a set of headphones and a sensor on a pole, and he walked my property the way I imagine a doctor moves a stethoscope across a chest, slowly, listening, asking the ground to tell him where it hurt.

He let me listen too, once, and I will never forget it. Through the headphones there was a faint, insistent hiss, far away and underneath everything, the sound of my own water escaping in the dark. He moved the sensor a few paces and the hiss grew louder, then softer, then louder again, and he marked the spot with a little flag. He told me the people who do this well are half plumber and half something else, part detective really, and that good leak detectors can place a buried pipe to within a few centimetres without lifting a single paver. All my dawn readings, all my graphs, and the ground had known the answer the whole time. It only needed someone who could hear it.

The leak was beneath the concrete driveway slab. The pipe ran under the very strip of concrete my car had sat on for twenty years, and the thought of breaking all of that open, the slab Marietjie and I had laid the year of the drought, filled me with a weariness I cannot describe.

Relief, and a quiet driveway

But it did not come to that, and this is the small mercy at the end of my story. Rather than demolishing the driveway and cutting a trench through my memories, they renewed the old pipe from the inside. What he did, he called pipe relining, a way of forming a new pipe within the shell of the failed one, so that the concrete overhead was never touched. I did not fully follow the chemistry of it and I did not need to. What mattered to me was that the slab stayed whole and the hissing stopped.

The next morning, out of pure habit, I went down at half past four with my torch and my notebook and read the meter with the house shut up tight. I stood there a long time in the cold, waiting for the little red dial to betray me again. It did not move. I waited longer, the way you wait to be sure a fever has really broken, and still it did not move. I wrote the two identical figures in my notebook, drew a line under them, and found that my eyes had gone blurry in a way the dark could not explain.

I have stopped the dawn readings now. The roses, freed of their secret flood, have settled back into being ordinary roses, and I tend them the proper way, with a watering can and my own two hands, which is how she would have wanted it. The bill came back down to its honest size. The numbers, in the end, had not lied to me. They never do. It only took a stubborn old teacher a very long time, and a stranger who could listen to the ground, to finally understand what they had been trying to say.
