Design of Side Drains, Bottom Drains, and Underdrains
Filter Drain (FD) is a computer program that allows quick and easy design (or review of design) of a filtration and/or an underdrain system of stormwater retention/detention systems. The stormwater retention/detention system can be ponds, lakes, underground trenches, wetlands, canals, rivers, etc., from which water is discharged via perforated pipes embedded in filter material (i.e., clean fine sand, gravel, natural soil, or other filter material). The Filter Drain has the following capabilities.
Input of initial design parameters, and then graphically review the default Filter Drain dimensions which are automatically selected.
Calculation of the required length of Filter Drain system to recover (discharge) a specified retained/detained volume of water from the retention/detention system within a specified period of time.
Tabular and graphical review of model results.
Generation of report-quality input and output data in a tabular and graphical format.
Generation of detailed graphics with design parameters and typical construction specification (which can be edited by the user) suitable for insertion into reports or construction documents
