500 Gallon Cistern
500 Gallon Septic |
Septic tanks were first introduced in Europe in the late
1800’s, and until recently, the design has remained
basically the same. Our Septic Tanks introduce several
new design enhancements to increase treatment efficiency,
assist in installation, and to provide longer service life. |

1400 Gallon Cistern
1250 Gallon Septic |
Optimum Treatment of Sewage
- The tank has 38 ft2
of surface area, which provides a bacterial zone with a
larger volume and a higher quality effluent.
- The compartment sizes are 2/3 and
1/3, which improves the removal of BOD and suspended
solids. Solids are digested in the first compartment,
where as the second compartment provides an area of
quiescent settling.
- Gas baffles prevent gas bubbles from
carrying solids to the second compartment.
- Watertight, threaded, 20” lids
(standard) and a threaded stackable 9” riser (optional)
provide easy access for inspection and maintenance.
- The 1250 Gallon Septic Tank is IAPMO
Certified.

Ease of Installation and Handling
- Lightweight for easy transportation
and installation.
- Handholds are provided to assist in
handling.
- Low profile tank design minimizes
excavation depth.
- Flat bottom makes it easier to
compact bed during installation and easier to clean the
floor of the septic tank, when cleaning sludge.
- Hold down ledge helps keep the
septic tank from floating.
