ABSTRACT
The Metropolitan Water District of Southern California (MWD) began construction of its 70 km (43.8 miles) Inland Feeder in April 1997 for which the estimated cost is $1.2 billion. The Inland Feeder will convey as much as 2.46 billion liters (650 million gallons) of water a day from the Devil Canyon Afterbay of the California Aqueduct of the State
Water Project in San Bernardino County to the Colorado River Aqueduct (CRA) and the recently completed Diamond Valley lake, in Riverside County. The project consists of constructing approximately 41.6 km (26 miles) of pipelines and 28.8 km (18 miles) of tunnels. Construction will last approximately eight years.
