The District's facilities are focused on moving and recharging water in the Santa Ana Spreading Grounds and the Mill Creek Spreading Grounds in the upper (East) ends of the Bunker Hill Basin. The District's Operations and Maintenance Manual is listed below and provides significant information on the facilities and operations.  These facilities mostly include weirs, diversion structures, canals, gates, control systems, recharge basins, wells, and related infrastructure including roads, processing areas, security fencing, and heavy equipment for maintenance.  The District cooperates with all the water entities in the valley to move, conserve, and recharge water for the benefit of the basin.
