Drinking water background info

• In Connecticut, about one fourth of people get their DW from a private well, usually in more rural settings. Sixteen percent of the US population uses a private supply, according to the USGS.
• In Connecticut, 77% get their DW from a public water supply (PWS), mostly in urban or suburban settings.

• In Connecticut, domestic water use is approximately 75 gallons per person per day (http://water.usgs.gov/watuse/pdf1995/pdf/domestic.pdf).
• The national average is higher (80 to 100 gpd per capita), due to greater lawn watering in dry parts of the country.
• Average per capita PWS use is 155 gallons per day in Connecticut and 179 nationally (http://water.usgs.gov/watuse/pdf1995/pdf/public.pdf).
• In contrast a person only drinks about one half gallon per day--less than 1% of water is consumed

How does a public water supply (PWS) work?
