How to read your water meter?

A number of people have asked how one reads the water meter.  Confused by the number of dials, spinning wheels and then the bar of digital numbers.  What does it all mean?

But first!  Do you know where your water meter is? Do you know how to switch off your supply if a pipe bursts or as happened to my neighbour this week – the flush mechanism of your toilet sticks and gushes drinking water into the toilet bowl.  The drought and stricter water restrictions make it even more critical that we also understand how to read our water meters and how to use them to check for leaks.   If you switch off all taps and the little black wheel is turning – then the chances are you have a leak.

See the diagramme of my old water meter annotated to explain what all the dials do!

How to read water meter

Apply for Cape Town eservices so that you can enter your water readings yourself on a specific date then your bill will take into account all liters used not just the kilo liters. Subscribing to an sms reminder service will let you know when you are due to take and enter a reading.

Our Constitution identifies access to clean water as one of our human rights. Many municipalities translate this into a free allocation of 6 kilolitres per household per month.

1kl = 1000 litres and 1 m³ (cubic meter of water)

In acknowledgement of the severity of this drought nationally AND understanding that the Climate Change scenarios for South Africa predict more frequent severe droughts, the Dept. of Water Affairs is reviewing the allocation of water by local authorities.   As a result in Cape Town, from 1 July 2017, affluent households will no longer get a FREE allocation of 6 kilolitres.   This is intended to encourage a culture of efficient use of water by homes with large gardens and pools and by people who can better afford rain tanks and alternatives to municipal water.  The new charge is also (possibly) the need compensate for the reduced revenue from the decreasing sale of water to pay for maintenance and new water infrastructure when the higher fees associated with the restrictions are lifted.  Hopefully this drought will have a lasting legacy of efficient water use. Many of us have learnt lessons in desperate times!!!

 Xanthea Limberg, CT Mayoral committee member for water services was quoted on Cape Talk as saying that  the higher water tariffs were designed to compensate for reduced consumption so that the City did not loose revenue to maintain the water infrastructure.  However, because of a slow response to the Level 2 and then the Level 3 water restrictions, the City’s revenue from water sales had increased significantly by R2.54 million over the past 12 months.  This extra funding was a welcome injection of money to speed up the City’s repair of old water infrastructure.

    hats wrong the one they mark as liters is 10ths of a liter, from top right counterclockwise its hundreds of liters then tens of liters then liters and the last dial on the left is tenths of a liter. That dial reads 8122 kilo liters 165.65 liters.

      One revolution is one litre and as you correctly say each position around this dial marks 1/10 of a litre. I have changed the annotation on the diagramme so it is clearer. Thank -you for pointing out the potential confusion.

    What could be useful would be a second image of the same meter, but taken a few days later, showing (obviously) some usage and a calculation for the difference so the reader can see how the dials have moved, and hence how the actual usage is arrived at.

    • admin May 30, 2017 at 5:32 pm #

      Good idea. But as we are using so little water will have to wait a few weeks to see a measurable shift.

    Hi admin.
    Should say “read dials CLOCKWISE”, not “read dials ANTI-CLOCKWISE”.

      done thanks!

    The spinning disc ‘spins’ all the time even though I am not using any water. Who should I contact about this?

    • admin November 3, 2017 at 2:25 pm #

      hi Susan, sounds as if you may have a leak on your side of the meter and you need to attend to it as soon as possible so as not to waste water and possibly be fined. Do you know where your isolating tap is? If so switch off your water supply and watch what the meter does – it should stop spinning. If not there is potentially a leak between the meter and your tap. As I understand it leaks on your side of the meter are your responsibility – so you need to get a plumber to fix this. Leaks on the city side of the meter are the City’s responsibility – but these leaks should NOT be turning your meter dial. If the leak is somewhere on your property and you can’t see dripping taps or toilets you may need a plumber to find it. To check for yourself – take a reading at night after you have stopped using water and then check again first thing in the morning. See what the consumption difference is – it should be nil.

    I’m furious! My husband and I really try very hard and save every drop of water that we can. We average 50 litres each per day, and am working on reducing that. 6 months ago when we discovered that our water meter had a slow leak, we reported it to the City of CT immediately and they replaced it immediately. However, without spilling more than a cupful at our gate, they replaced it with a meter which already had a reading of 609 litres on it. I phoned in to complain and emailed and sent photos of the old and new meters on the day of repair, but to no avail. That 609 litres remains for our account. We are paying for an extra 6 days or 20% of a month’s worth of water that we didn’t use! What a slap in the face. Apparently because its less than a kilolitre it doesn’t show up on either council workers readings or the readings that I phoned in. Please can anyone advise me on how I can have these 609 litres reversed off of our account?

    • admin November 6, 2017 at 11:22 pm #

      hi,It looks like sloppy workmanship by the City. The 609 litres will result in you reaching the 1000 ltr mark (1 kilolitre ) much faster and therefore the first payment mile. You can carry on protesting or just accept that you will pay for it – probably at the rate of R4.56 per kilo litre for consumption up to 6 kilo litres. Well done for being a water warrior. If all Captonians used 50litres per day we would reach the City’s target of 500 million litres consumption per day and delay the dreaded D- Day of the dams running dry.

    Dear Admin

    This is an INCREDIBLY helpful article! You have explained everything perfectly! Thank you, THANK YOU for posting it!

    Good day, who do I contact in CoCT to have my existing Water meter cleaned. The numbers are covered in Algae from the inside and now the Water reading man can not read the numbers on the dials. I was told it is just a matter of taking the meter off and giving it a good shake and flush. I do not need to replace the meter. Please let me know who I can contact at CoCT.

    Thank you for this helpful page. I would like to know if water meters in Cape Town include the outflow or the sewage/waster water flow as well. I am calculating our water usage and need to know if I should divide my reading in roughly half to really understand our usage. Thank you.

    • admin January 29, 2018 at 4:41 pm #

      Hi, the water meter measures the total water consumption of the building – not the outflows. The inflow includes the water you flush if you are flushing your toilet with the municipal supply. To work out how much water you are flushing you need to measure the volume of your toilet cistern in litres and multiply this with the number of times you flush. To measure the volume of your toilet cistern you need to flush and then stop the inflow. then manually fill your toilet using a container of known volume. A litre jug or bottle works well. Hopefully you are managing to fill your toilet cistern during the drought with shower, washing machine water, swimming pool or borehole water. We need to save as much potable water as possible. hope this helps.

    Thank you a most helpful article. I even called the Municipal help line but got nowhere.

    Good morning, We recently had individual water meters installed in our Estate. Owners and tenants still pay the same for water every month. I am doing the readings. Just correct me if I am wrong regarding the readings.

    Flat 102 – 37.123 is it 37000 liters and 123 hundred (4 in the flat)
    Flat 22 – 4.462 is it 4000 liters and 462 hundred (1 in the flat)

    Your feedback would be appreciated.

    • admin February 12, 2018 at 6:02 pm #

      Hi Flat 102’s meter appears to have recorded 37 kiloliters (37000liters) and one hundred and twenty three litres. The City charges for the kilo litres used each month. Presumably the 37 kilolitres was used over a number of months otherwise the consumption is excessive. Flat 22’s meter appears to have recorded 4 kiloliters (4000liters) and four hundred and sixty two litres. 4000litres for one person per month is way over the old prescription of 87 liters per person which equals 2610 litres per month. Now the target is 50liters per person per day. The households in these flats need to reduce their water consumption significantly – or they or the complex will be liable for high water costs and we will all be facing Day Zero with only 25litres that we have to collect ourselves. .

    Hi, we just want to know if you can let us know how many liters there is in one unit of water? We live in a security complex with individual water metres, but get our reading in units?

    • admin February 12, 2018 at 6:05 pm #

      As the City charges for water in units of 1 kilolitre which equals 1000 litres I assume that the units you are being charged for are multiples of 1 kilolitre units.

    Good day.,I hope my text find you well.
    I’m in desperate need of advice regarding our residential water meter. Our problem started a few years back when local municipality decided to move and replace all existing water meters and replacing them with the current plastic ones. At first our meter was inside our our yard and placed it on the outside..
    I would like to know why is there still a stop valve inside our yard. He we want to stop the water flow we need to close both valves.. And shortly after we noticed excessive increase on our monthly water bill. Various times we query our bill and various times we got told that our reading was incorrect and that we don’t have to pay the entire Knott stated on our bill..
    Please tell me What’sthe reason that we need two stop valves.. Prior their change everything was perfect. I checked with our neighbors and theirs differ from ours.. He they want to kill or completely stop their water flow..they only close the 1 valve on their meter ..if we intend on completely stopping our water flow.. It’s require to turn both valves the existing ~+the new valve on the plastic never.. Is this normal?

    • admin February 19, 2018 at 4:37 pm #

      Hi Shawn, sorry I do not work for the City – am an independent sustainability auditor and can’t answer your questions and why you have to turn off both valves. I can only assume that the inside value is for your convenience in case you need to do plumbing and need to switch off your supply. Not sure why you would also need to turn off the supply at the City meter. The meter would be outside your property to make it easy for the reader to access it>
