Water hardness level in St. Petersburg for a dishwasher

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

Average annual figures

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

Main waterworks. Water has a hardness of less than 1.1 ⁰F – very soft water. It has no smell or taste. Color is no more than 6 degrees with a standard of 20. Turbidity is less than 0.15 mg/cubic meter. dm with a norm of no more than 1.5. pH – 6.6 with a norm of no more than 9.
Southern waterworks. Water hardness less than 1.2 ⁰G. There is no smell or taste. Color is 5 degrees with a standard of 20. Turbidity is 0.24 Mg/cubic. dm with a norm of no more than 1.5. pH – 6.5 with a norm of no more than 9.
Volkovskaya waterworks. Water hardness less than 1.0 ⁰G. No smell, no taste. Color – 7 degrees. Turbidity – 0.18 mg/cubic. dm. pH – 6.6.
Northern waterworks. Water has a hardness of less than 0.9 ⁰AND.There is no smell or taste. Color – 7 degrees. Turbidity – 0.34 mg/cubic. dm. pH – 6.5.
Water supply station in Kolpino. Water hardness less than 1.0 ⁰G. Has no smell or taste. Color – 6 degrees. Turbidity – 0.38 mg/cubic. dm. pH – 6.5.

Official data tells us that the entire city has soft water, which means it is necessary to set the hardness indicators on the PMM to the minimum. However, residents of the southwest of St. Petersburg claim that their water is hard. The fact is that some of the water is not taken from the river. Neva, but from artesian wells.

Some wells have hard water and supply it to the homes of residents in 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 the question: from what sources is water supplied to your address? If you are told that your street’s water supply comes from an artesian well, most likely you are dealing with water of medium or high hardness. The State Unitary Enterprise “Vodokanal of St. Petersburg” has information on the level of water hardness by region.

Is this water suitable for the dishwasher?

In most areas of St. Petersburg, the water is indeed very soft. It's dishwasher safe. 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 well water, pay attention to how quickly scale builds up on your kettle. If you have to clean your electric kettle frequently, it means your water is hard, and this is bad for the PMM.It is necessary to take additional measures to soften the water, including installing expensive flow-through 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, this is also important for human health, because many people use this water (even after a 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. Is this true or not? Most likely, people exaggerate as always. Water treatment is carried out at the highest level.

The water is treated with sodium hypochlorite, while the ratio of chlorine ions in the outlet water is minimized.
Next, treatment is carried out with environmentally friendly ammonium sulfate.
Lastly, the water is exposed to powerful ultraviolet lamps, which effectively kill bacteria and viruses.

The purity of water supplied to the homes of residents of St. Petersburg is controlled not only by technicians and laboratory specialists. Recently, water quality control has also been entrusted to crustaceans, or more precisely to crayfish. The cancer body reacts sensitively to the presence of various chemicals in water, so as long as these small creatures are guarding clean water, people have nothing to fear.

So, we found out that in St. Petersburg, at least 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 to you and wish you good luck!
