Local health department codes largely determine the requirements and options for installation. If you have any doubts or specific questions, it’s best to consult your local health department for detailed guidelines and adhere to their instructions.

Infiltrator chambers are versatile for various septic leachfield applications, effectively replacing traditional stone and pipe systems. They are suitable for trenches, beds, and elevated mound installations. These chambers excel in multiple applications including pressure dosing, level distribution, serial distribution, evapotranspiration, and sand filter applications, offering enhanced treatment capabilities.

The sizing of septic systems is determined by local health departments, which often allow for a 25 to 50 percent reduction in size when using Infiltrator chambers. It’s important to consult your local health codes for specific requirements in your area.

Some health codes do not allow septic leachfields to be installed under impervious surfaces such as driveways. This is because the surface pressure can compact the soil, resulting in a negative effect on the soil’s ability to treat effluent (wastewater). Check with your local health department for the specific codes for your area. If this type of installation is allowed, call at +18445444242 for design and installation instructions.

Infiltrator Water Technologies recommends a minimum of 12 inches of compacted cover over the chambers. Maximum allowable cover over the chambers in a trench system is 96 inches. In bed systems, the maximum cover is 48 inches. If the drainfield is located in a non-traffic area, minimum cover can be reduced to six inches. Exercise caution with equipment when installing a system at the 6-inch depth. Infiltrator Water Technologies does offer a line of Shallow Cover (SC) Chambers that allow for six inches of cover with an H-10 equivalent loading rate, however these are only available in specific markets. Always check with your local health codes for specific cover requirements.

Yes. To accommodate existing obstacles in system installation, the Quick4 Chambers allow for 10 to 15 degree turns, right or left.

Yes, on the top of each chamber there is a knock-out area that is typically used for an inspection port. When inletting into the inspection port, a splash plate is needed under the inlet. Use caution when backfilling so as not to dislodge the inlet pipe.

Infiltrator chambers have a patented MicroLeaching™ louver design that corresponds to the angle of the soil. This permits effluent to leach out of the sidewall while preventing soil from entering the chamber.

Infiltrator MicroLeaching™ sidewall louvers are designed to keep soil out; therefore filter fabric is not needed. Contact us for additional information at +18445444242.

When installing the chambers in sandy soils, mound, or fill systems the sand base should be compacted. This gives the chambers a solid footing and does not adversely affect the infiltration rate of the sands.
