How to calculate your water and sewage bill

Clic here to open our simulator. 

Dear Customer,

Our fees will change from March 15th, aiming the adjustment of charging process established for Florianópolis, and now Jurerê Internacional too.

The main change is the extinction of the “Minimum Fee” of 10 cubic meters, whose value was R$ 45,19.

In the new model, the fee will consist of a fixed amount, referring to the availability of the Infrastructure, named Fixed Infrastructure Availability Fee (TFDI), whose value will be R$ 29.49, plus the variable amount according to the water volume consumed by the unit.

In summary, your account will be = TFDI (R$ 29.49 + Cost of the water consumed(s).

The cost of the sewage fee remains equal to 100% of the water fee.

This change aims to encourage conscious consumption of water.

Below is the table with the fees readjusted, in the different consumption ranges, for the water consuption from march 15th to april 15th and water and sewage bill for may 10th, 2020.

NOTE: SEWAGE RATE = 100% OF WATER RATE VALUE

Note:

In Jurerê Internacional we practice two categories of fees: Residential and Commercial.

A building, can have both types of fees in one single bill, for exemple: a building that is both residential and comercial, the water bill is calculated according to the economy category and consumption ranges.

Now let’s see three practical examples of how calculate your water and sewage bill using the above table:

Ex. 1. A home where the monthly consumption of water is = 3 m³
Calculation: 01 Economy – Range 1 = 3m³ x R$1,96 = R$ 5,88
water billing value = R$ 29,49 (TFDI) + R$ 5,88 = R$35,37

Water and sewage total bill = R$35,37 (water) + R$35,37 (sewage) = R$ 70,74

OBS: Remember that your sewage fee is equivalent to 100% of the water consumption.

Ex. 2. A home where the monthly consumption of water is = 32 m³
Calculation: In this case we have 01 Economy in 3 consumption ranges.
Range 1 –10 m³ x R$1,96 = R$ 19,60
Range 2 – 15 m³ x R$ 9,11 = R$ 136,65

Range 3 – 7 m³ x R$ 12,18 = R$ 85,26

water billing value = R$ 29,49 (TFDI) + R$ 19,60 + R$ 136,65 + R$ 85,26 = R$271,00

Water and sewage total bill = R$ 271,00 (water) + R$271,00 (sewage) = R$ 542,00

OBS: Remember that your sewage fee is equivalent to 100% of the water consumption.

Ex. 3. A building with 12 apartments and 4 stores with total consumption of = 432 m³ (mixed economy)
Calculation: In this case we have 12 residential economies and 4 commercial economies.
432 m³ / 16 economies = 27 m³ – This is the consumption of each one of the economies:

Range 1 Resid – 12 Resid. Econ. = 10m³ x R$ 1,96 = R$ 19,60
Range 2 Resid – 12 Resid. Econ. = 15 m³ x R$ 9,11 = R$ 136,65
Range 3 Resid – 12 Resid. Econ. = 2 m³ x R$ 12,18 = R$ 24,36
Total residential: R$29,49 + R$ 19,60 + R$ 136,65 + R$ 24,36 = R$ 210,10 x 16 economies

Total residential: R$ 210,10 x 16 economies = R$ 2.521,20

Range 1 Commercial – 04 Comercial Econ. = 10m³ x R$ 4,34 = R$ 43,40
Range 2 Commercial – 04 Comercial Econ. = 17 m³ x R$ 12,18 = R$ 207,06

Total commercial: R$ 29,49 + R$ 43,40 + R$ 207,06 = 279,95

Total commercial: R$ 279,95 x 4 = R$ 1.119,80

Water total bill = R$ 2.521,20 + R$ 1.119,80 = R$ 3.641,00

Water and sewage total bill = 2x R$ 3.641,00 = 7.282,00

OBS: Remember that your sewage fee is equivalent to 100% of the water consumption.

Using the water meter as an ally

The unit of mesurement used by the water meters to register the water consumption is the cubic meter (m³). The totalizer mechanism is composed by cyclometer cylinders (idlers) combined with pointers. The number of the smallest division of the totalizer, which is the smallest quantity of water it registers, is 0,0001 m³ (or 0,1 litre). The water volume consumed in a given period is calculated simply by the difference between the initial and final reading of the monitoring. To calculate the flow, just clock the time between the two readings, and divide the difference between the readings by the time obtained.

How to do the reading

It’s easy to do the reading of a water meter; you should read the numbers in black and discard the rest. That way, in the water meter below, the reading is 9999.

It’s recommended that the owner does the periodic readings of the water meter, so in that way it is possible to obtain the average daily consumption. In case of a significant consumption increase, with no apparent reason like visits, swimming pool water Exchange, etc., immediately check the hydraulic installation, because there may be happening some leakage. In case of any leakage detected, register it with pictures and communicate it to SAE immediately, through the number (48) 3261-5587.

Detecting Leaks

In building installations the detection of leaks must be analysed since the entrance of the water through the pipes to the installed products. There are some products available in the market to help detect leaks, like acoustic sensors, among others.

Check some tips to detect leaks and its expenses. Leaks can be visible or not. The visible ones happen in faucets (garden, tank, kitchen sink), in the float of the water tank or in the built-in pipeline. In the last case, the humidity will appear on the walls.

See on the table below some types of leaks, their flow and how much water you lose in sanitary vases. We should analyse by how many washing holes is the water leaking, to check how much water was lost in a month.

TEST 1

Extension that supplies water from the pipes to the float of the water tank. Follow the steps to check possible water leaks:

1. Keep the pipe register open.
2. Turn off every faucet in the house and do not use the bathrooms.
3. Turn off the faucet of the float of the water tank completely, not allowing the entrance of water.

4. Mark the position of the biggest pointer of your water meter, after one hour check to see if it has moved. 5. In case it has moved, it’s a sign that there is a leak in the extension supplied directely by the water supplier net.

TEST 2

Extensions proceeding from the water tank.
Follow the steps to check possible water leaks:

1. Turn off every faucet in the house and do not use the bathrooms.
   2. Turn off the faucet of the float of the water tank completely, tying it inside the water tank, not allowing the entrance of water.
2. Mark the level of water in the tank and after one hour, at least, check to see if it has lowered. 4. If it has, there are leaks in the pipeline or in the bathrooms supplied by the water tank.

If it is a building with underground water tank, you should turn off the booster pumps, doing the same procedure, adding the marking of the level of water inside the underground tank, watching the level of water to detect any possible leaks.

TEST 3

Sanitary ware.
Throw in some cigarette ashes or pigment in the sanitary vase and watch. The ash or the pigment must stay in the bottom of the vase; if that doesn’t happen, there must be some leak in the flush valve. In the sanitary vase with the water container attached: put on some strong pigment in the water container. Wait 15 to 20 minutes; if the water in the sanitary vasi is colored, then there might be a problem with the water container mechanism.
