Water use and tariffs

Condominium use is a type of use that affects both condominium administrators and private customers who live in small housing complexes served by a single meter.

You can choose between different uses within the contract, depending on your needs. Each use has different tariffs:

  • Condominium use

The supply has one or more meters shared between different housing and non-housing units.

  • Other uses: irrigation and collective use

The supply is used to irrigate condominium gardens or green areas of the condominium.

  • Other uses: different use

The supply is used for the shared parts of the condominium

In case of supplies for condominium use with a single meter shared between different residential and non-residential real estate units, the installation of separate meters can be requested. In fact, separating the meters avoids “mixed” users, which also include non-domestic supplies, usually linked to commercial establishments that access the shared meter. If each apartment is the holder of its own user, it will receive a bill that's more in line with its real consumption, based on the household composition.

The application of the preferential tariff will be based on the number of apartments that make up the condominium and the number of family members who live in each apartment. In the absence of data on the number of members of the household, a standard criterion is applied which considers three members per apartment. This is why it is important to communicate personal data (residence/non-residence and number of people). If you haven't communicated them yet, please send an email to assistenza.clienti@gruppocap.it. For mixed condominium users, who therefore use the supply for residential and non-residential purposes, the fixed component applies in the same way as for domestic users. For real estate units with non-domestic use, on the other hand, the minimum fixed component established for uses other than residential use will apply (users with meter diameter 15).

For irrigation and collective use, it is not necessary to communicate the number of household members, moreover there is no preferential tariff bracket, nor is there a tariff related to sewers and treatment. For irrigation and collective uses, the minimum fixed component established for non-domestic use applies (with meter diameter 15). The fixed component is calculated based on the diameter of the installed meter. It is important to carefully assess your supply needs, choosing the best ratio between the meter size and your consumption.
