Do you want to reduce water consumption in your housing company by 25–50%

Facts about the average water consumption of an apartment building:

155 litres / resident / day
The average water consumption in an apartment building is 155 litres per person per day. 40% of this is warm water.

10 min / 150 litres
A shower of about 10 minutes consumes 120-150 litres of water, of which 60% is hot water.

20 min / day = €600 / year
A 20-minute daily shower costs around €600 / year. The yearly cost of a 5-minute daily shower would be around €150.

Average water consumption:

•      Kitchen 35 L (22%)

Billing according to consumption creates uniformity and equality

Nobody wants to pay for a neighbour’s water consumption. And now you don’t have to, because we have the solution for you: a HYDROLINK system that is scalable according to your needs!

Making the right choice can have an effect on your fees

An old-fashioned, per-resident water fee usually only covers a small fraction of the actual cost of water use. The remaining part will be paid by all shareholders in the form of a maintenance fee. Is that fair? No. Our HYDROLINK system follows water consumption 24 hours a day, every day of the year. The system has its own accurate meters for cold and warm water. The housing company can decide the interval of billing according to consumption, e.g., monthly or every 3 months. Billing information can be easily transferred to the billing system already used by the property manager. All major billing systems are already supported and support for new ones will be added as soon as they enter the market.

When deciding on and comparing water meters, please consider the following factors:

  • Are the water meters CE/MID certified?
  • Additional Home Displays are not obligatory when it is possible for the resident to check the meter readings easily on the meter itself.
  • Can the water consumption be checked from the meter itself?
  • Do the meters give accurate measurements and is the reading data securely stored if there is a power failure or low battery?
  • Are the meters and the system genuinely maintenance-free?
  • Calculate yourself what the actual payback period of the investment is.
