How much will a leak add to your Gold Coast water bill?

Whywait Plumbing how to read your water meterYour Gold Coast water bill issued by the City of Gold Coast as a Water and Sewerage Rate Notice arrives every three months. Currently, every water meter is manually read every three months with your Gold Coast water bill coming soon after. The cost of water is set every year as part of the budget process with the detailed current water pricing for 2020-21 available from Gold Coast Water.

What are the costs on your Gold Coast water bill?

For most homeowners who use around the average daily water usage of 451 litres, the highest costs in the quarterly Gold Coast water bill are their sewerage and water access service charges. If you look closely at your water bill you can see that you have the following access charges:

Residential Charges Cost
Sewerage access charge per quarter

$181.03

Water access charge per quarter

$53.02

Total Access Charges per Quarter

$234.05

The usage charges per kilolitre as measured by your water meter are made up of council charges and Queensland Government charges as below:

Residential Charges Cost

City of Gold Coast water per kilolitre

$1.090

Queensland Government water per kilolitre

$3.122

Total Cost of Water per Kilolitre

$4.212

In reality, even if you did not use one drop of water, you would still pay for water and sewerage access service charges of $234.05 every quarter or $936.20 every year.

In our experience, the average water use of 451 litres or 0.451kL per property is not an accurate guide to your water use. Most homes with more than one occupant will use 1-2 kL every day. Remember your water usage will vary every day based on the number of occupants at home each day, and their water use behaviours. That is why we recommend you read your water meter weekly as that will give you a better guide about your average consumption but will also alert you to a potential water leak.

The real cost of water dripping from a tap

What will cause your usage charges to blow out is having leaking water. Leaking taps and toilets are frequently overlooked and put off to another day. A dripping tap that drips one drop every second will use 40 litres of water a day. The reality is that it becomes 280 litres a week and then 1214 litres a month and then 14560 litres a year. This is all water charged for on your Gold Coast water bill that you never utilised for any useful purpose.

If we translate the litres wasted to the cost of water, then the numbers become real.

The real cost of a leaking underground water main

A dripping tap or running toilet you can visually sight but the real killer to your Gold Coast water bill is your underground water main pipe leaking. For residential users, these are usually leaking polypipe water mains that were never installed correctly when the house was built. Only occasionally is a water leak apparent and bubbling to the ground. Most of the time they are a silent Gold Coast water bill killer leaking 24/7 undetected.

There is no real average for any leaking water main because it depends on the type of break in the pipe and what the incoming water pressure is.  Currently, we have a small leak where we have water monitoring installed that is leaking on average of 44 litres per hour, so we use that as a basis for what a leaking water main will cost on a Gold Coast water bill.

Cost of a leaking underground water main at 44 litres per hour Residential Cost at $4.212 per kL or 1000 litres Business Cost at $8.662 per kL or 1000 litres

16016 litres per month

$67.459

$138.731

192192 litres per year

$809.513

$1664.767

A leak at 44 litres per minute is only a small leak. It is highly unlikely to show up bubbling to the ground unless it is directly under the grass in a shallow trench. Even looking at your water meter, it will not be evident unless you are testing your water use at the meter by checking for a water leak.

How much does a leak cost per litre

We have always recommended that you test your water usage through your water meter every month. By having comparable figures, you will soon ascertain whether you have a leaking pipe.

We have always recommended that you install an AquaTrip water leak detection system after your water meter. An AquaTrip Water Leak detection system with an integrated automatic shutoff valve supplied and installed by Whywait Plumbing is a permanently installed leak detection protection system that quietly protects against leaks 24/7. It is a one time only insurance payment.

With our modern leak detection methods, it’s a much easier job to find a leak but unless you have an AquaTrip installed or use our water monitoring service you will still pay for a lot of lost water before you become aware of the leak.

If you think you have a leak contact us because every litre that you lose is costing you $0.004212 for residential properties or $0.008662 for businesses on your Gold Coast water bill. If you believe that is inconsequential, we have just rectified a leak for a business client that was in a 40mm underground pipe that was leaking 96 kL every day, which is 96000 litres every 24 hours. This leak was costing $831.55 every day.

Your Average Gold Coast Water Bill is Always Out of Date

Your Average Gold Coast Water Bill is Always Out of Date

Most property owners on the Gold Coast have just received their City of Gold Coast Water and Sewerage Rate Notice for January. Under Queensland law, you must receive a quarterly water bill. The City of Gold Coast issues their water bills in January, April, July and October.

gold Coast water meterWhenever water bills arrive, we get clients asking us why their Gold Coast water bill is always out of date. From experience, we can guarantee the average Gold Coast Water bill is still out of date. For example, most water bills issued in January were for water that was used between July and October. This is due to the contractors who read each water meter having set routes and timelines to read your meter so yes your usage charges are always at least two months out of date. This is why we suggest you monitor your water meter weekly and read how to do it on our page “How To Read Your Water Meter”.

For most homeowners who use around the average daily water usage of 451 litres, the highest costs in the quarterly water bill are their sewerage and water services charges. If you look closely at your water bill you can see that you have the following charges:

  • Sewerage service charges – sewerage access                   $181.03 per quarter
  • Water service charges – water access                                  $53.02 per quarter
  • Gold Coast Water – water usage per kilolitre                          $1.09
  • Queensland Government – water usage per kilolitre              $2.91

In reality, even if you used no water, you would still pay for service charges of $234.05 every quarter or $936.20 every year.

Average water use of 451 litres or 0.451kL per property is not an accurate guide to your water use. In our experience, most homes with more than one occupant will use 1-2 kL every day. Remember your water usage will vary every day based on the number of occupants at home each day and their water use behaviours. That is why we recommend you read your water meter weekly as that will give you a better guide about your average consumption but will also alert you to a potential water leak.

If you suspect a water leak, call Whywait Plumbing and ask for our leak detection service.

Gold Coast Council Water Rates to Increase

Gold Coast Council Water Rates to Increase

Gold Coast council water rates are about to increase again. For both homeowners and business owners, this could be a double whammy when you couple this with the increases in power bills in recent years.

The Increases are likely to continue in coming years even though the City of Gold Coast has not increased its portion of your water bill at all for three years. Bulk water charges for the City of Gold Coast are recommended to increase by the Queensland Competition Authority a further $12 a year for the next two years.

The City of Gold Coast has now finalised the 2018-19 budget. Your Gold Coast council water rates charges will not increase on the retail and distribution component of the water and sewerage charges from the last financial year.

However, the significant portion of your water cost which is Queensland Government’s bulk water price will increase in line with the recommendations by the Queensland Competition Authority. The bulk water price will increase by 2.5% from $2.74 per kilolitre to $2.91 per kilolitre.

Contrary to some urban myths City of Gold Coast no longer owns Hinze Dam and the desalination plant. Gold Coast Water buys the water that you use through your meter from Seqwater owned by the Queensland Government. The price paid for the bulk water is itemised in your water bill.

Essentially the bulk water charges levied by the Queensland Government makes up the bulk of your water bill.

These charges are still reflecting the poor planning from 20 years ago that resulted in the multi-billion dollar water grid construction in 2007-08 which resulted in supply pipes connecting all of South-East Queensland being built. To a large extent, the pipe grid was constructed without dams being built and to lesser extent dams constructed without pipes which also resulted in the construction of the seldom-used Tugun desalination plant.

For 2018-19 your Gold Coast council water rates will increase on 1 July for your water and sewerage which will comprise of the following charges:

  • Queensland Government bulk water charge $2.91 per k/L
  • City of Gold Coast distribution           $1.09 per k/L
  • Total water consumption charge    $4.00 per k/L 

The water and sewerage access charges will remain the same as in previous years being:

  • water access charge of $212.08 per year
  • sewerage access charge of $724.12 per year.

Currently, water charges are relatively stable, but significant problems are looming. Long term planning is required to address the issues of aging infrastructure and their maintenance costs which will impact Gold Coast council water rates.

Infrastructure Australia in a major report has predicted water bills will go the way of power bills increasing by at least $50 every year. They predict today’s average annual water bill of $1200 will increase to $2500 within 20 years.

The report correctly says we need to start planning now as our dams are relatively full which gives us the rare opportunity of “….clear thinking and long-term planning to meet our future needs.”

As we all know from the water management supply crisis of 2007-09 South East Queensland can be adversely effected quickly with a combination of natural disasters, poor planning and below average rainfall.

Very simply if we don’t start long-term planning now for planning our future water needs the drastic increases in water bills will cripple family and business budgets in the same way power bills are now.

Preventative Maintenance Is Critical Plumbing Advice For Business Owners

Every business relies on many factors and unexpected disruptions are an everyday occurrence to be managed . From a plumbing perspective the best management technique is preventative maintenance which is critical plumbing advice for business owners. One of the most disruptive plumbing problems faced by business owners is a sudden leak or failure of a plumbing appliance or fixture. (more…)

The Risks of Living With High Water Pressure?

Do you know the risks of living with high water pressure because I frequently listen to clients of Whywait Plumbing recollecting the days gone by when high water pressure was the norm. For many high water pressure had been a bonus, especially when water was virtually provided for free. High water pressure enabled many to stand in one spot and water the whole garden or to literally pressure clean the car or driveway.

Both Gold Coast and Logan council areas in the past had high water pressure delivery. Frequently in excess of 800kPa and often as high as 1100kPa. In reality high water pressures caused many problems with damage to pipes, appliances, taps, valves and fittings from water hammer which also reduced their operational life plus caused excessive noise in the water reticulation system.

Legally under Australian Standards, AS/NZS 3500.1:2003, Plumbing and Drainage – Water Services, the relevant clause is 3.3.4 which states, “Maximum pressure within buildings – Provision shall be made to ensure that the maximum operating pressure at any outlet, other than a fire service outlet, within a building does not exceed 500 kPa.” This was further reinforced with amendments in 2010 to clause 3.2.1 which states, “The maximum flow rate from a shower, basin and kitchen sink or laundry trough outlet shall not exceed 9 L/min.”

These very clear definitions within Australian Standards create a dangerous situation that many home and building owners are unaware of. This is because they have the incoming mains water pressure set above the maximum legislated operating pressure of 500kPa level for most connected plumbing fixtures. These plumbing fixtures include dishwashers, washing machines, ice makers, boiling water units, mixer taps, refrigerators with water dispensers and hot water systems.

Having excessive water pressure can cause you more problems than you may be aware of. Aside from damage to pipes, appliances, taps, valves and fittings from water hammer which also reduced their operational life plus caused excessive noise in the water reticulation system, you may also be voiding your property insurance and manufacturer’s warranty on any number of these expensive household appliances.

Most insurance policies and appliance warranties are void if your water pressure is above the recommended operational levels. This will always come back to the requirements of Australian Standards which is of course 500kPa.

Most hot water system warranties are void above 500kPa once again with the reference point being the requirements of Australian Standards. Many people are fooled into thinking they have a compliant system as they have pressure limiting valves installed. In reality the majority of these valves over 3 years old are faulty and in need of replacement.

As council water retailers will not guarantee supply pressures the onus is back on home and building owners to ensure they are compliant with Australian Standards. Most homes and buildings constructed since 2003 have pressure reduction valves installed after the water meter but these frequently require recalibration. Homes and buildings constructed before 2003 seldom have a pressure reduction valve installed which means they are susceptible to the fluctuations in water supply pressure.

The risks of high water pressure can be devastating on multiple fronts so if you are unsure of what your water pressure is and whether your system is compliant in regard to your insurance policies then contact Whywait Plumbing Services now to carry out a comprehensive analysis of your incoming water pressure to ensure you are aware of the risks of living with high water pressure..
