FORMCELL Living Filter® www.formcell.com formcell@nitrap.com Connecticut (860) 604-6146 - (203) 605-6095 EFFECTIVE LEACHING AREA RATING (Adjusted to State of Connecticut Department of Health Formula) for Leaching and Filter devices approved for use with Septic Systems in the State of Connecticut as approved by the Commissioner of the Connecticut Department of Public Health The Products are listed in order of efficiency to deliver effluent into the subterranean. A higher rating will reduce space requirements for both the main system and the reserve area*** for most installations. This will preserve the environment by providing greater separating distances to sensitive areas such as water supply wells, aquifers, open streams and water in addition to providing more lot area for other uses. All devices are measured for
the total wetted perimeter (actual surface area where the biological clogging
layer forms). The State of Connecticut Board of Health then
assign an "Interface Factor (IF)" to the wetted perimeter interface.
Some products may have more than one type of interface and are thus assigned
a factor for each. The IF or the combination of more than one type
of interface allows the CT DPH to assign en Effective Leaching Unit (ELU)
for each product which leads to a rating in sf per lineal foot of installed
device.
