In a nonpressure aqueduct, water moves downhill under the force of gravity. Ancient aqueducts were usually of the nonpressure type.

OBS

Closed conduits, such as aqueducts, pipelines, and tunnels, may also follow the hydraulic grade line, in which case they are called grade structures, or they may operate under pressure.

OBS

Aqueduct. ... In ordinary usage, ... the term is applied to large arched structures of masonry conveying water by gravitation, ... and the earliest aqueducts ... had therefore to be built on the hydraulic gradient, i.e. the slope at which the water would flow freely.
