Water  - Frequently asked questions


Tap water consumption

1. What is the difference between tap water and bottled water?

Regarding bottled water:

Hundreds of billions of plastic bottles are used annually for water packaging. These immense amounts of PETs quickly become waste and only 16% are recycled. The remaining of 84% pollute the nature, being biodegradable in such a low level that they disappear only after hundreds of years.
3 litres of oil are required for the production and marketing of one liter of bottled water.
Researchers estimate that extending this way of water marketing would cause a real disaster in the next decade.
Regarding cold tap water:
From the river and up to your faucet, passing through treatment plants, the water is continuously monitored. The main water parameters are continuously analyzed through a series of analyzers, supplemented by the network samples and analyzed in the laboratory.


2. I think I have excessive water consumption. How can I evaluate my consumption?

The water consumption varies according to:
• habits (water is used for drinking, in the kitchen, for the toilet or washing clothes), equipment (household appliances, pool)
• domestic use (bath, shower, watering the garden, washing the car)
• new events in the family: the increase in the number of people staying in the same house etc.
You may calculate an estimated annual consumption here.


3.  Are there any faucets that allow me to save water?

If you use an efficient shower head, you may reduce water consumption. The new shower aerators help to achieve a sensation similar to that of a powerful jet, by using less water.
Mixed taps that allow opening and stopping water while adjusting the flow rate and water temperature may also be found on the market.
4. Which is the “normal” pressure?
The water pressure at your faucet depends on the house location in relation to the water tank/ basin and/or branch pipe. The “normal” pressure ranges between 2 and 3 bars (bar = unit of pressure).


Water taste and colour

5. The water does not have the same aspect and taste it usually has. What should be done?

If you have not used the water for a longer period (days, weeks), the water that first flows is the one that remained in your system.
Every time you notice a deterioration in the appearance of your tap water we recommend:

• letting the water run for a few seconds
• learning whether the water was cut for interventions
• checking whether your neighbors have the same problem.
You must not allow unauthorized interventions in the water system or in the internal network.


6. The water tastes or smells of chlorine. What can I do?

The more pronounced smell of chlorine appears in case of extreme temperatures (high or low) and in the situation where, in order to ensure the microbiological safety (bacteriological) of distributed water, it is necessary to increase the concentration of disinfectant to the upper limit of the maximum amount admitted.
Chlorine is a volatile substance. In order to alleviate the taste, leave the water into an uncovered container or recipient before drinking. If possible, even in a refrigerator, but no longer than 24 hours. The cold will dissipate the taste. Or you can serve it with ice cubes. Also, a few drops of lemon or a mint leaf will make the chlorine taste disappear and the new flavors may be quite agreeable.


7. Why does the water sometimes have a reddish/brown color?

When the water distribution network displays a high pressure, iron micro particles may detach from the pipes, thus leading to the coloring of the tap water. Even though they do not present a health hazard, it is preferable to drink the water only when it returns to its normal aspect.



1. I do not have heat inside my apartment - the interior distribution pipes are clogged and half the radiator is cold – what can I do?

According to Article 14 of the Law 230/2007, «The owner is obliged to maintain his individual property, apartment or space with another use than that of housing, in good condition at his own expense. No owner can disrespect, impact or affect the right of common property or individual property of the other owners in the building. »
As well, Article 56 of the same Law states: «  (1) The following actions are seen are offenses:
a) if the Owners’ Association, the owners or the Executive Committee do not take all necessary measures to repair and maintain in good condition the building and the common distribution columns  throughout their existence ;
c) if the owner does not make all maintenance, repair and replacement works on all elements of structure and installations found on his private property and which could prejudice  the other owners; »
Thus the owner’s obligation to maintain at his own expense the interior distribution installations in his apartment can be deduced. To this scope, he can call on the Owner Association, which can play the role of intermediary for any repair/ maintenance work on the interior columns, who, in change, can call upon the heat supplier or any other authorized company.


2. Why should I pay the heat losses from the substation to my apartment building? How much does Veolia Energie pay for these losses?

The thermal energy losses between substations and the apartment building connected to the district heating network are not, in any case, paid by the clients. These are technological losses which exist in every heating network, centralized or individual. Veolia Energie’s clients pay only the quantity of thermal energy (Gcal) registered by the meter at the base of the building, based upon which our company makes the invoice.


3. How can I disconnect from the district heating network?

Individual disconnections in apartment buildings can be done only by respecting  legal dispositions detailed in Law no. 325/2006, in the Rules and Regulation of the public district heating networks approved by order of the President of the National Regulation Authority for Public Utilities Services no. 91/2007, and by Local Council Decision no. 444/2008 in Iași, and Local Council Decision no.353/2011 in Ploiești, which establish unitary heating zones in  Iași, and Ploiești. The technical and legal implications and consequences of illegal disconnections impact the individual apartments that take this decision, the safety of people inside the building and the other owners who will suffer later prejudice.


4. How much do I pay for one cubic meter of hot water?

Veolia Energie supplies thermal energy injected in cold water. The invoice is made based on the recordings of the meters and reflects the consumption of thermal energy injected in the cold water in order to prepare hot water (Gcal) for the month in which the thermal energy invoice was computed.
The volume, expressed in cubic meters, registered by the hot water meter is transmitted to the water supplier, in order to be invoiced as tap water used to prepare hot water.
Thus, hot water price is made of two components:

  • The thermal energy injected into the cold water, used to prepare the hot water
  • The cold water volume used to prepare hot water, invoiced separately by the water provider in the city


5. Why is there a difference between the quantities registered by the water meters in my apartments and the ones registered by the general meter of the building? Do I pay the losses of Veolia Energie ?

There are multiple causes for the difference between the sum of the meters in the apartments and the general meter at the base of the building: assembly errors, the difference of precision class between the meters in the apartments and the general one, illicit consumption.
The losses are not paid by the clients: the clients only pay the thermal energy registered by the general meter of the building. Technological losses on networks represent exploitation costs, in charge of which is the operator.
The metrological verification of the meters before deadline in case of suspicion, can be demanded, in conformity with article 8 point 7 of ANRSC Order no. 483/2008 ,form a written request to verify the meters installed on the connection of the building, for any flaws or suspicion of errors in registration, under the condition of article 7, point 14”


6. Does the disconnection of an apartment in the building have any negative effects on the other apartments? If so, which are these consequences?

Heat and hot water pipes are systems which ensure  the efficient supply of thermal energy.
Interventions on interior columns (disconnections), lead to important dysfunctionalities  and to bigger costs for thermal energy for the apartments connected to the district heating network.    

 Disconnection percentage 10-20% 20-35% 35-65% 65-95%
 Impact on the invoice of those still connected + 5 % + 40 % + 80 % + 90 %


7. Why do I pay cold water at the price of hot water? Why do I have to waste so many liters of water until cold water turns hot?

According to the thermal energy supply contract, the district heating network operator is obliged to respect quality parameters for the supply of heat and hot water at the point of delimitation if its responsibility, which is the general meter, found more often in the basement of the building.
Years ago, there were no issues concerning the temperature of the hot water that reached the tap of the final consumer: the needed quantity was consumed and the costs were divided according to the number of people living in the apartment.
The installing of water meters inside each apartment lead to economies of the quantities of water used. These economies, alongside the lack of insulation on the interior pipes of the building, as well as the periods in which there is practically no consumption (especially during the nights) make so that the hot water stagnates: this is why when the client opens the tap (especially in the morning), the hot water temperature is lower than the one supplied in the substation or the thermal module by the operator.
So, even if the operator supplies the hot water at the correct temperature at the delimitation point, the temperature will decrease inside the interior installations of the building until reaching the tap of the client.
 The technical solution to this unpleasant issue is very simple: if there already exists a recirculation pipe from the substation to the building, a recirculation installation can be constructed inside the building. It means the installation of a pipe parallel to the hot water pipe which will recirculate the hot water from the last floor to the meter and back. The pipe is tied to a pump which has a temperature detection unit. The clients decide which is the temperature they want/ need for the hot water and, if the sensor will detect a decrease in temperature, under the established value, the pump will start to function automatically, recirculating the water from the last floor to the meter in the basement and further, to the substation, ensuring the optimal comfort.
This technical installation can be made for every building that is confronted with the issue of lower temperature hot water.
