Conservation: Water: Water Costs

flowing water
Unsure what your water costs per gallon? Here we will help you calculate it for yourself. 


City Water:
Usually you are charged a service fee + a fee for water used. Many times that water used will appear on your water bill as a charge per 100 Cubic Feet. Below is a calculator to convert cost per 100 CF to cost per gallon. Some water systems charge on different "tiers" based on water usage. If you are on a tier system, try to average out your cost for this calculator. Remember, some sewer utilities will also make charges based on your water usage. Make sure you use this in your calculations.
Personal Well:
Here, we make some estimates of how much electricity is needed to pump a gallon of water from your well. This may not be the most accurate estimate because there are other factors. 
Personal Water Catchment:
There are initial set up costs, maintenance and of course, it may not rain as much in your area. At this time we will not provide a calculator for this.
