Multifamily Water Conservation Case Study | Confidential Client

16.49% Reduction in Water Consumption

A multifamily property in Washington, D.C. installed a 2-inch AF valve to reduce unnecessary water consumption and associated water and sewer costs.

Performance was measured over 122 days and four billing cycles, comparing post-installation consumption with corresponding prior-year periods using a same-season, matched-cycle methodology.
