The total capital cost of the Monterey County Water Recycling Projects was approximately $78 million. The total cost to treat and deliver reclaimed water to agricultural areas is estimated to be approximately $0.19/m3 ($225/acre-foot or $0.90/1,000 gallon) excluding secondary treatment costs but including both debt service from low interest loans and operation and maintenance costs for the two components (i.e., treatment facilities and distribution network) of the MCWRP. The 114,000-m3/d (30-mgd) wastewater reclamation plant was completed in 1997 and began delivering 76,000 m3/d (20 mgd) of reclaimed water for food crop irrigation in 1998. Reclaimed water is used to irrigate lettuce, celery, broccoli, cauliflower, artichokes, and strawberries. The service area is about 4,800 ha (12,000 ac).
