Frequent Questions

How much does it cost to treat and deliver drinking water?

It costs less for our drinking water than it does for most other goods and services, such as cable television, telephone service, and electricity.  On average, tap water costs are slightly more than $2 per 1,000 gallons, although the costs tend to be lower for large water systems, and higher for small systems.  Treatment accounts for about 15 percent of that cost.  Other costs are for equipment (such as the treatment plants and distribution systems), and labor for operation and maintenance of the system.  Yet think about how important water is to our daily lives.  The average person uses over 100 gallons of water per day for everything from drinking and bathing to watering gardens.  This equates to an average annual water bill of about $300 per household, though costs vary considerably across the country.  Additional facts and information on drinking water is available at
