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.

The District has water rights for the diversion of water from the Santa Ana River and Mill Creek for recharge.  The District also has land in Fee and easement for the recharge of water, preservation of habitat, mining, and other uses.  The District cooperates with adjoining land owners and easement holders such as San Bernardino County Flood Control District, City of Redlands, City of Highland, East Valley Water District, Robertsons Ready Mix, Bureau of Land Management, Southern California Edison, and many others.  The District lands are resources for endangered habitat, critical local building materials (sand/gravel/concrete), open space, and recreation in the future.  The District also generates sand and other materials from the cleaning of its basins that is frequently available.
