The Donald C. Tillman Water Reclamation Plant began continuous operation in 1985. Its facilities were designed to treat 40 million gallons of wastewater per day and serve the area between Chatsworth and Van Nuys in the San Fernando Valley. The plant was named after Mr. Tillman, who was the City Engineer from 1972 to 1980.
A major construction project that doubled the capacity of DCTWRP was completed in 1991, expanding the plant from 40 million gallons of water per day (MGD) to 80 MGD. The Donald C. Tillman Water Reclamation Plant and the Los Angeles-Glendale Water Reclamation Plant (LAG) are the leading producers of reclaimed water in the San Fernando Valley.
