<br /> The following general specifications describe the installation, general operations, and
<br /> maintenance requirements for the Americast stormwater bioretention filtration system, the
<br /> Filterra®. The system utilizes physical, chemical and biological mechanisms of a soil, plant and
<br /> I microbe complex to remove pollutants typically found in urban stormwater runoff. The
<br /> treatment system is a fully equipped,pre-constructed drop-in place unit designed for applications
<br /> in the urban landscape to treat contaminated runoff.(t a • E_'.t 1. yl t, ry ` y

<br /> Stormwater flows through a specially designed filter media mixture contained in a landscaped
<br /> concrete container. The mixture immobilizes pollutant, those pollutants are then decomposed,
<br /> volatized and incorporated into the biomass of the Filterra® system's micro/macro fauna and
<br /> I flora. Stormwater runoff flows through the media and into an underdrain system at the bottom of
<br /> the container, where the treated water is discharged. Higher flows bypass the Filterra® to a
<br /> downstream inlet or outfall.
<br /> IMaintenance is a simple, inexpensive and safe operation that does not require confined space
<br /> access, pumping or vacuum equipment or specialized tools. Properly trained landscape
<br /> personnel can effectively maintain Filterra® Stormwater systems by following instructions in this
<br /> Imanual.
