As quoted from the maker "norweco", "The Singulair
system is the state-of-the-art alternative to a troublesome septic tank for domestic wastewater treatment. Employing the extended
aeration process, the Singulair plant provides flow equalization, pretreatment, aeration, clarification, tertiary filtration
and optional chemical addition within a single precast concrete tank. The only mechanical component is the fractional horsepower
aerator, which runs at 1725 RPM and is certified with a 30 minute per hour run time. The patented Bio-Kinetic device is an
integral component and assures that all flow through the Singulair system is equalized and completely treated.
Designed for domestic wastewater flows ranging from 500 to 1,500 gallons per day,
performance of the Singulair system is certified by NSF International and the Canadian Standards Association. Sold only through
local, licensed, factory-trained distributors, the Singulair system is backed by Norweco’s fifty year warranty and exchange
program. The Singulair system is a trouble-free answer to domestic wastewater disposal and insures a safe, sanitary home environment."
