Use numbers for the month, even though your bill shows letters for the month. For example: 14/May/2010 becomes 14/05/2010 Alternatively, click on the calendar provided next to the blank box, and click on the date that represents the Fecha de Vencimiento on your bill. The calendar will put the date in the blank box in the correct format for you.

Click on Factura Actual (current bill). Your current water bill will appear. At the top right, you will see the payment due date (Evite el Corte Pagando Antes de). At the bottom right, you will see the amount due (Total a pagar). In between, you will see other water bill information, such as your meter number, dates covered by this bill, next meter reading date, monthly amount consumed, etc. If you have paid your bill in advance, you will see the amount of credit remaining (Saldo a Favor).

There are other online options on this page, but the ones above are probably the most useful.

Water Charges

Water is charged on a sliding scale based on usage. The first 5 cubic meters (5000 liters, 1320 US gallons) are included in the base charge of around 40 pesos a month, including IVA tax. You are charged this 40 pesos even if you use no water.

Cubic meters from 6 to 10 are charged at 2.62 pesos each cubic meter (each 1000 liters, 264 US gallons). Then the price increases to 3.51 pesos a cubic meter, and carries on increasing as your consumption increases - by the time you get to 50 cubic meters, it's 10.52 pesos a cubic meter.

There is an online calculator for these charges (select Población 71 for San Felipe).

At the beginning of each year there is a discount for paying in advance.

I hope this information is helpful to you. I have found the water company to be very easy to deal with, and their online system is quite user-friendly. Good luck with your water bill!
