Save on your water and energy bills thanks to smart meters!

Achieving savings on fixed costs is not always easy. However, levers do exist, particularly thanks to advanced water data analysis. Detailed knowledge of consumer habits makes it possible to better control consumption of domestic hot water, reducing both water and energy costs. A financial and environmental advantage.

Water and energy are two important areas of expenditure for households and savings can easily be achieved by taking simple steps. According to the INSEE, a French household with 2.5 people uses 329 litres of water a day. Consumption varies according to the number of people in the household, their age and the size of the home and garden, etc. Household appliances which are sometimes unsuitable and too old may also be responsible for unnecessary consumption. For example, one flush can consume up to twice the amount of water needed for this function, varying between 6 and 12 L of water. Producing hot water is highly energy intensive. Indeed, it is estimated that one cubic meter at 37 °C costs about as much in water as the energy required to heat it. Hot water is also the usage with the highest impact on the environment and represents, on average, more than 75% of the carbon footprint of water use in homes.

With the ON’connect™ coach service, SUEZ offers an application that reduces water bills and energy bills as well, by encouraging optimised consumption of water and hot water.

Daily and monthly analysis and personalised advice

Available via the consumption monitoring platform, if the community has subscribed to the service. This application allows households to fill in their profile, including simple but crucial information in the analysis of consumption, such as the number of people, the existence of a garden and its size, or the method of producing hot water. Once these details have been filled in, residents can access an analysis of their consumption per day and then per month. Their data will also be cross-referenced with other households with a similar profile in order to categorise consumption into three types: "high", "medium" or "eco". For a better understanding of the savings made, consumption is converted into Euros. Finally, practical tips are displayed to encourage residents to reduce their consumption of water and hot water. For example, the application may suggest more economical and environmentally friendly appliances. An economical shower head, for example, has a flow rate of less than 7 L/min. A 4-person household using a shower head with an average flow rate of 8.5 L/Min will make a saving of €90 per year by purchasing this device. And, by reducing their time in the shower by one minute, this home may also achieve an additional saving of €60 per year.

Deployed as a pilot scheme with certain contracts, this new proposal adds value to the relationship with users of the service.
