Reactor Tank
(if applicable, for two tank systems)
Supply and install the reactor tank in accordance with applicable State or Local regulations. The
reactor tank must be watertight against ground or surface water infiltration and/or exfiltration.
Install reactor tank on stable, compacted fill (e.g. stone ≤1” or similar material).
Reactor tank must be backfilled with suitable material as recommended by the manufacturer.
Backfill must be free of debris and large or sharp objects.
Install water tight risers over access ports to provide access for maintenance and sludge removal.
Install aerator stand, siphon/sludge pump stand, clear water discharge pump stand, and
other components per installation checklist. The aerator, siphon/sludge pump, clear water
discharge pump, timer float, and high water alarm float heights are factory set.
Install siphon/sludge return line from the pretreatment tank to the reactor tank in accordance
with applicable State or Local regulations. The siphon/sludge return line must be adequately
supported to prevent damage during backfilling.
Secure the pre-drilled siphon pipe in the pretreatment tank with the top 3/8” hole at the
correct height as indicated in the design.
Connect the clear water pump discharge line to the drainfield in accordance with applicable
State or Local regulations.
Backfill and grade around the reactor tank to prevent infiltration of surface water.
4.4
Site Restoration
The riser lids must be installed above grade with the ground landscaped to divert storm water
away from the area.
Backfill should be suitable, loose, workable material.
Backfill must be free of debris and large or sharp objects.
Compact backfill sufficiently to adequately prevent settlement.
Landscape (e.g. grass seed, sod, straw, landscape stone, xeriscape, etc.) the sloped backfill area
and any trench excavation
lines with a suitable indigenous seed variety or use other methods.
PROVIDE EROSION PROTECTION AS REQUIRED PER DESIGN PLAN.
Installation Warning
If you are not using an air break on
the clear water pump discharge pipe,
then install a check valve!
Construction Warning
During construction, harmful
chemicals such as paint and
solvents can harm the system
microbes if dumped down the
drain. These items should not be
allowed into the treatment plant.
