Testing under stringent US & Canadian standards
Years of extensive testing in Stokes Canada
Biomat established in 3 weeks or less
Operating at less than 30 mg/L TSS & BOD
NSF 40, class 1 approved
Currently approved in NH, ME, IN, OH, CT, NY, VA,
MA, NJ and VT

System Advantages
– Gravelless, large diameter pipe providing
secondary effluent treatment & dispersal
– Provides Unmatched treatment prior to
returning liquid to the ground water
– Leach field/Trench sizing is typically 25-60
less than traditional pipe & stone
– Trenches are sized under GSF
– Smaller dispersal area translates to more
savings

New York Sizing
•

Amount of AES pipe is based on volume of water and
wastewater strength
Residential bed systems will use a minimum of 70 linear feet
per bedroom
Non-residential systems are sized according to BOD & TSS
levels
Sizing
g of the bed ‘Footprint’

is based on the conservative Tyler

System Restrictions
• System placed on 1-60 MPI soils
• Higher perc rate soils with waiver
• System must be vented
• Must be at least 6” of System Sand Above,

What is System Sand?
The System Sand acts as the
“lungs” of the field.
Fine sands,
sands silt & clay retain
water, restricting air flow.
ASTM C-33
C 33 (Concrete Sand) with 2%
or less passing a #200 sieve can be
used as System Sand (pg 9 QR).
** #200 value obtained by washing the sample **
