- In my water bill (in U.S.), there are two charges, one for water consumption and the other for sewer consumption. I was wondering what the difference between water and sewer is?
- This month, our water and sewer have the same amount of consumption. I was wondering if their consumptions are supposed to be the same generally?
- Is the water from bathroom sink or bathtub supposed to be drinkable? If further after being boiled, is the water from bathroom sink or bathtub safe for drinking?
Water is the amount of water coming into your house. Sewer is (usually) the portion of it that you use inside the house and that goes out through your drains, toilets, etc. See #2 below. Sewer charges may also include a portion for storm water if your downspouts feed into a municipal sewer system.
During the summer, it's expected that some of the water will be used for watering your yard, so your sewer usage will be less than your water usage. During winter, the two should be very similar.
In general, water in bathroom fixtures should be safe to drink, boiled or not; there's only one water main coming to your house, after all. You may have additional filters on the water lines going to the kitchen faucets, which would make that water taste better (by removing chlorine, say).
My county has the option to have a deduct meter installed on your irrigation system, so the amount of water used for irrigation is not charged on the sewage.
They used to automatically deduct a portion of the sewage for water used during the summer that exceeds the average of the three winter months. They have discontinued that program.
So to answer question 2, it is possible in some locations to have a different amount of consumption depending on the rules of the water and sewage municipality.
Despite what folks think, water charges are not based on the price of water, and only loosely based on consumption.
Water prices are based on the annual infrastructure cost to maintain the water supply AND waste management systems divided by the predicted total annual water usage.
What you get charged for supply vs sewage is fairly simple math based on the municipalities relative costs for each of the above. The portion YOU pay vs. your neighbor is calculated from the water meter reading.
It is a VERY common occurrence in districts where you are asked to conserve water for reasons such as contamination, or drought, for the water rates to GO UP so you end up paying the same amount. Why? Because it costs the city pretty much the same amount to maintain the services regardless of usage.
Now if we could only figure out how to make them bring it down again after....
