<p><strong>Representative Figure</strong><b>:</b> Schematic of the <span style="text-decoration: underline;">proposed</span> integrated system <span style="text-decoration: underline;">combining</span> rainwater reuse <span style="text-decoration: underline;">with</span> waterless toilet tents<br /><br /><br />My only question is does Figure 1 show just one system (i.e., the proposed system) or more than one?<br /><br />If only one, I assume it is the proposed one in the paper. If true, then Figure 1. Schematic of the proposed rainwater treatment system.</p>
