Roof staircase and water tank plan layout in AutoCAD, dwg file.

<p>This Architectural Drawing is AutoCAD 2d drawing of Roof staircase and water tank plan layout in AutoCAD, dwg file. Storage tank of water is kept at roof top&nbsp;<strong>to store energy as potential energy</strong>&nbsp;and we do not need any external input to access water at lower level. The tank serves two purposes:&nbsp;<strong>providing water for washing and drinking, and providing water for fire suppression to standpipe outlets in stairwells and or sprinkler heads</strong>.&rdquo; Rosenwach adds that as pumping stations became better built, the majority of buildings 12 stories or less do not require a gravity tank.</p>
