<br /> Size and cost estimates:
<br /> The StormFilter is a Oow-based syslem, and therefore. is sized by calculaling the H�ater quality flow rate associated
<br /> with the design storm. The water qualiry flow rate was calcutated using tne SBUH method with a 6-month reinlall of
<br /> 0.99 inches in 24-hours.
