Brothersoft Editor: ExFiltV4.1 (ExFilt version 4.1) is a program that calculates the drawdown time of water in storm water ponds and exfiltration systems under unsaturated and Saturated flow or ground water mounding conditions to provide a total drawdown time for treatment volume in a stormwater treatment facility. It uses the Simplified Analytical Method to make the calculation for drawdown time under saturated flow conditions.

Calculates total drawdown time for treatment volume in storm water ponds and exfiltration systems. Both unsaturated and unsaturated flow conditions are considered. Drawdown times occurring under saturated flow conditions are based on the Simplified Analytical Method as presented in SJ93-SP10 and the St. Johns River Water Management District Applicant’s Hand Book.

Calculates drawdown time for unsaturated and saturated flow (ground water mounding) conditions only.

· Approved by St. Johns River Water Management District (SJRWMD).

· Does not calculate flow time through structures.

· Calculation is automatic when data fields are changed or ENTER key pressed (recommended after final change to data for final Results).

· Capability to adjust porosity of storage media in trenches based on pipes in the system.
