We are metered and pay 4.50 peso's a month. 3.50 is for water and 1.00 is for sewage. The water we get in our area of POP is based on rain fall. We have had very little rain over the past few months and the water tanks are almost empty. We get water maybe twice a month. So I have to purchase it by the truck load on occasion. It also costs $4.50 pesos'.
