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. </div><div><div><font color="#5856d6"><span style="caret-color: rgb(88, 86, 214);"><br></span></font></div><div>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.</div><div><br></div><div>Had these been closed tanks, the question would never have arisen! </div><div><font color="#5856d6"><span style="caret-color: rgb(88, 86, 214);"><br></span></font></div><div>Matt Goodman</div><div>Columbus, Ohio, US</div><div><font color="#5856d6"><span style="caret-color: rgb(88, 86, 214);"><br></span></font></div><div><img alt="PastedGraphic-1.png" src="cid:AC3DDA38-DE07-4A87-A083-1FA78F708F06" width="575"></div><div><font color="#5856d6"><span style="caret-color: rgb(88, 86, 214);"><br></span></font></div><div><div><img alt="E605813A-24C8-4457-9396-7A60B1EDAB26.jpeg" src="cid:F13AF901-4CAF-47D7-AFA2-46D7939881B1"></div></div></div><br></body></html>
