Modeling Open Water Tanks

[NW Mailing List]

A month ago I discovered the treated water tanks at the Dorney coaling station I’m modeling are open on top, Petticoat Junction style. Dorney, like Portsmouth in the attached photo, has three water tanks; one for the raw water, and two for treated water. See the first photo. 

My question is partly from wanting how to model this, but partly curious from an industrial practice point of view. When there were two finished / treated water tanks, was water drawn from one, then the other (some treatment plants worked in this “intermittent” / batch way), or were the pair treated as a single tank, drawing water from both?  The photo shows equal heights, which suggests the latter, but I’m curious if anyone has direct knowledge of this.

Had these been closed tanks, the question would never have arisen!
