Twenty Household Test Results

In 2004, WaterSaver Technologies conducted a 24-hour, 20 household tests to determine the various contaminants and volume of fresh water which goes down the bathroom drain. The contaminant data, along with information published on the Internet and discussions with our toxicologist, was used to develop treatment options to make the reused water safe for pets and people.

The volume data, which was later validated by an independent study by Aquacraft, Inc., provided information regarding anticipated fresh water and wastewater savings. The following is a review of the data collected.

Six households, (30%), of the households tested used in excess of nine (9) gallons of fresh water per day in their lavatory sink. The average of these was 12.5 gallons. The range of fresh water savings is between 3,500 and 6,500 gallons of fresh water per year and an equal amount of wastewater savings.

Another six households (30%) used between 6 to 8 gallons per day. This amounts to 2,200 to 3,000 gallons of fresh water per year and an equal amount of wastewater savings.

The remaining eight households used less than 6 gallons per day.
