Except for Soil Type 0, the LTAR may vary, depending on the Soil Type and the Treatment Level of the effluent.
You may adjust the LTAR for Soil Types 1-5 by choosing different Treatment Levels, but for Soil Type "0" the LTAR
will always be "1" regardless of Treatment Level. Remember that HLT systems are always pressure-dosed, so no
additional sizing reductions are given for Manufactured or Chamber distribution media for HLT systems.
DISCLAIMER: the OWTS Regulations may limit sizing options based on types of systems, effluent application
methods, treatment levels, etc. Not all of the sizing options shown in the calculated tables will apply
to every system. These calculations must be verified by the design engineer.
