Summer luxury of tenants — who pays for watering lawns and filling pools?

During hot months, water consumption in apartment buildings and hotels increases by 30–50%. But often, those who cause the overuse do not pay for it.

With each hot season, water supply networks operate under increased load, and utility bills grow.

According to statistics in countries of Europe, Latin America, and Central Asia:

• In summer, water consumption in the residential sector increases by an average of 35–50%,
• In the private sector, up to 40% of water goes to pools, car washing, and lawn irrigation,
• However, only 12% of tenants actually pay for the overuse.

The reason is the lack of individual control: in most properties, tenants use water on an “all-inclusive” basis — without meters or with one general building meter.

This means:

• One resident may water the lawn every evening — 200–300 liters,
• Another fills a pool — 5 tons,
• A third washes a car with the tap constantly open, and all costs fall on the owner or are shared among neighbors (if one house is rented by two or three families).

This is not only economic injustice but also an environmental threat.
In conditions of drought, overheating, and lack of drinking water, such losses are an unaffordable luxury.

The hidden burden that remains with the owner?

• Direct losses: water bills can increase by up to 80% during the summer period, especially in houses with several tenants.
• Conflicts with tenants: owners are often forced to raise the rent “just in case” to cover losses — as a result, loyalty drops.
• Unjustified consumption: when no one is responsible for overuse, water is consumed 2–3 times more than the norm.
• Breach of contract terms: tenants use the property for unintended purposes (pools, washing, water slides), but it’s almost impossible to prove without monitoring.

ADDERRA is a water sub-metering system developed by ADD GRUP. It is designed specifically for hotels, residential complexes, rental housing, and apartment buildings, where it is important to control the consumption of each user.

In rental properties, the ADDERRA water meter is installed and managed via a smartphone app.
ADDERRA offers a prepaid mode — without balance top-up, water supply can be limited.
The integrated valve shuts off water in case of overuse, leakage, or non-payment, and the ultrasonic technology detects even minimal consumption — from 1 liter per hour.

The question is not about banning people from using water in summer.
The question is about fairness and transparency.
Everyone has the right to comfort, but also the duty to pay for what they consume.

ADDERRA allows property owners to:
✔ reduce losses,
✔ control consumption in real time,
✔ motivate tenants to save water,
and finally sleep peacefully, knowing that no one lives at someone else’s expense.
