3800 rubles – the average tariff for the installation of two meters. This amount already includes the cost of purchasing the devices themselves.
1200 rubles – this amount will have to be paid for the verification of two meters. The metering device for cold water will need to be verified every six years, hot water – once every four years.
Let’s try to find out whether it is profitable to install metering devices and how soon their installation pays off.
For each person registered in the apartment, according to the standard, 6,93 cubic meters are allocated per month. m of cold water and 4, 74 cubic meters. m of hot water.
If we multiply this amount by the tariff, it turns out that without meters, every resident must pay:
Cold water: 6,93 x 29,16 rubles. = 202 rub.
Hot water: 4,74 x 135,79 rubles. = 643, 64 rub.
Total costs per person will be 845,71 rubles.
Are there two people registered in the apartment? Water per month will cost 1691 rubles.
Considering that a family of two pours on average about 6 cubic meters. m of cold water and 3 cubic meters. m of hot water, the savings with meters are obvious.
Monthly expenses will be:
Cold water: 6 x 29,16 = 174,96 rubles.
Hot water: 3 x 135,79 = 407,37 rubles.
Total: 582,33 rubles. Savings per month equals 1160 rubles.
It turns out that the installation of meters pays for itself in 3,5 months. As for the costs of verification, it is easy to calculate that if it is carried out once every four years, then the costs of this operation should be divided by 48 months. It turns out that the cost of verification will slightly increase the cost of water.
1200/48 = 25 rubles. a month.
