Apartment meters cut water use 15%: Study

摘要

Washington — A two-year study of water billing practices in the multi-family residential sector has found that the practice of installing individual water meters on multi-family apartment units and billing based, on actual consumption results in water savings of 15% or 8,000 gallons per unit per year. The study discovered that billing apartment dwellers based on allocation methods (commonly known as "RUBS" or Ratio Utility Billing Systems) did not result in any water savings.
