3D Video Sequences for Water System Project Explainer

I am producing a video in Final Cut Pro for a client that explains a completed project that built an entire water system for a city. The video is a supplement to a report I produced for the client (see upload). For the video, I need some 3D renderings of the system to insert into the video. (See the uploaded script.) The client has attempted a video but ours must be better. I can share the client's video. I also have a sample of the video that the 3D video will be inserted in so the design can match seemlessesly: [login to view URL] The system has been explained in infographics in the report (uploaded), but those infographics need to come to life with the 3D video. It would be good if the 3d video sequences incorporated both photos of the real system as seen in the infographics in the uploaded report.
