Water hardness level in St. Petersburg for a dishwasher

For normal operation of the dishwasher, the user must know about the quality of the water that enters his water supply. Mainly, it is important to know the water hardness level in order to set the appropriate parameters on the PMM itself. Today we decided to talk about what level of water hardness in St. Petersburg? Indeed, what parameters should be set for users of PMM living in different areas of the city? Is there soft water or hard water? Now we find out.

Annual average

If we take into account the philistine opinion, it boils down to one thing - in St. Petersburg the water has always been soft. Of course, we will not base our conclusions on rumors and gossip, but turn to the data published by the State Unitary Enterprise Vodokanal of St. Petersburg. First of all, we will determine the average annual fluctuations in water hardness. As it turned out, they are insignificant, so we will not take them into account.

1. Main water station. Water has a hardness of less than 1.1 ⁰F - very soft water. It has no smell and taste. Chromaticity is not more than 6 degrees with a standard of 20. Turbidity is less than 0.15 Mg / cu. dm at a rate of not more than 1.5. pH - 6.6 at a rate of not more than 9.
2. South water station. Water hardness less than 1.2 ⁰G. There is no smell or taste. The color is 5 degrees with a standard of 20. Turbidity - 0.24 Mg / cu. dm at a rate of not more than 1.5. pH - 6.5 at a rate of not more than 9.
3. Volkovskaya water station. Water hardness less than 1.0 ⁰G. No smell, no taste. Chromaticity - 7 degrees. Turbidity - 0.18 Mg / cubic dm. pH is 6.6.
4. Northern water station. Water has a hardness of less than 0.9 ⁰G. There is no smell or taste. Chromaticity - 7 degrees. Turbidity - 0.34 Mg / cubic dm. pH 6.5.
5. Water station in Kolpino. Water hardness less than 1.0 ⁰G. There is no smell or taste. Chromaticity - 6 degrees. Turbidity - 0.38 Mg / cubic dm. pH 6.5.

Official data tell us that the whole city has soft water, which means that it is necessary to set the hardness indicators on the PMM to the most minimal. However, residents of the south-west of St. Petersburg claim that they have hard water. The fact is that some part of the water is not taken from the river. Niva, but from artesian wells.

In some wells, water is hard and it is supplied to the homes of residents of the southwestern part of the city.

If you live in the southwest, it makes sense to call the State Unitary Enterprise Vodokanal of St. Petersburg or go to their official website and ask a question: from what sources is the water delivered to your address? If you are told that the water supply to your street is from an artesian well, most likely you are dealing with medium or high hardness water. The State Unitary Enterprise Vodokanal of St. Petersburg has information on the level of water hardness by region.

Is this water suitable for dishwashers?

In most areas of St. Petersburg, the water is really very soft. It is good for a dishwasher. First, less salt is needed to restore the ion exchanger resins. Secondly, the ion exchanger itself lasts much longer. And, thirdly, there is no need to spend money on additional filters and water softeners, since it is already of high quality.

If you live in an area that is supplied with water from a well, pay attention to how quickly the scum on the kettle grows. If you often have to clean the electric kettle, it means that your water is hard, and this is bad for PMM. It is necessary to take additional measures to soften water, up to the installation of expensive flowing softeners.

How is water prepared in St. Petersburg?

Knowing the water hardness level for dishwashers is very important. But this is important not only for dishwashers, but also for washing machines. In the end, it is important for human health, because many people use this water (albeit after the filter) for food.

There is an opinion that the quality of tap water in large cities, in particular in St. Petersburg, leaves much to be desired. So is it or not? Most likely, people as always exaggerate. Water treatment is carried out at the highest level.

1. Water is treated with sodium hypochlorite, while the coefficient of chlorine ions in the outlet water is minimized.
2. The following is an environmentally friendly ammonium sulfate treatment.
3. Last but not least, water is exposed to powerful ultraviolet lamps that effectively kill bacteria and viruses.

The purity of the water supplied to the homes of residents of St. Petersburg is controlled not only by the technicians and specialists of the laboratory. Recently, water quality control has also been assigned to crustaceans, and more precisely to crayfish. The cancer body is sensitive to the presence of various chemicals in the water, so while these small creatures are on guard of clean water, people are afraid of nothing.

So, we found out that in St. Petersburg, in any case, in most of the city the water is soft. If you are interested water hardness level in Moscow, read the article of the same name published on our website. And we say goodbye and wish good luck!
