&lt;p&gt;If you need to model complex interactions with groundwater/aquifers, that&amp;#39;s when the SWMM extensions can be used which Sushma mentioned.&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: How to Design Perforated Pipes in Inroads Sanitary Sewer</title><link>https://communities.bentley.com/thread/629986?ContentTypeID=1</link><pubDate>Wed, 20 Jan 2021 03:00:17 GMT</pubDate><guid isPermaLink="false">6dad98f5-dbc9-4c4d-a9ba-e9da8dc6aa8e:34c18fbf-3d5c-46fd-bbd9-a6a89b74182a</guid><dc:creator>Sushma Choure</dc:creator><description>&lt;p&gt;Hello Sepideh,&amp;nbsp;&lt;/p&gt;
&lt;p&gt;&lt;span&gt;For this purpose you can use the Explicit (SWMM) solver (selected in the calculation options) &amp;gt; groundwater module. The aquifer can be defined under Components &amp;gt; SWMM Extensions &amp;gt; Aquifers.&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&lt;span&gt;Here is information on these SWMM extension and modeling aquifer.&amp;nbsp;&lt;/span&gt;&lt;/p&gt;

&lt;p&gt;&lt;span&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&lt;span&gt;Please see below similar forum detailed discussion on modeling perforated pipes, for your reference.&amp;nbsp;&lt;/span&gt;&lt;/p&gt;
