Enhancing Water Efficiency in Student Accommodation: A Sodexo Case Study

Control Flow HL2024® was installed into two groups of identical student apartments, where each had the same amount of bathrooms and kitchens. One apartment was selected for the test, with Control Flow HL2024® Inline being installed at each water inlet. A meter was also installed on the hot and cold feeds to measure the consumption and savings. The second apartment was used as a control room, where only the meter was installed to measure comparative usage.

Water consumption was measured over a period of time (see graph below) by recording the daily meter readings. Cenergist were able to accurately calculate the difference in consumption between both apartments showing a saving of 105 litres per day in the apartment where HL2024® was installed. The following savings were observed:
