DWR Table 4-1 and DWR Table 4-2 include IRWD’s quantified water distribution system real losses. Tables indicating “actual” water loss were calculated for “wet water” (real water losses) in accordance with American Water Works Association’s (AWWA) developed methodology. Apparent water loss are additional losses, separate from the physical distribution system, such as adjustments made during the billing process.
