Mannequins

Jeffrey theorizes that the mannequins, posed by the Stenmark twins, symbolize one of two things: they are either the ancestors of contemporary people or the descendants of contemporary people. The latter seems more likely as later in the novel, Jeffrey sees a human figure and assumes it is a mannequin, but it ends up being a preserved human. The human is preserved, similar to how those in Zero K have been preserved, which is a product of the future.

Water

The concept of what water symbolizes in the novel is explicitly stated by Artis; she states that water symbolizes evolution, as it starts in one form and gradually morphs. This includes the evolution of humans and human technology. Humans have morphed from a species of creatures with short lifespans, to, thanks to The Convergence, a species with an almost limitless lifespan and potential.
