PBI developed Calaveras County Water District’s (CCWD) LaContenta sewer system model using H20 Map Sewer Suite 8.0. The system was modeled using construction as-built drawings for various sections of the collection system. All model components were based upon the best as-built drawing information available. The LaContenta sewer system model contains both existing and proposed system components. The proposed system components include four (4) additional housing developments that have not been constructed yet.
