Septic tank leach field alternatives.
The name refers to the construction of the drainfield.
Placing the drain field leach field on undisturbed soil is a standard specification for conventional septic systems and many alternative systems such as mounds.
Plastic chamber leach field.
Here is an explanation of a sand filter septic system.
A conventional septic system is typically installed at a single family home or small business.
This system uses a standard septic tank but instead of the conventional pipe leach field the leach field is made of interlocking polyethylene arches that provide a continuous drainage area.
The effluent seeps into the gravel from the perforated pipes and then the soil.
The chambers create an empty space for effluent to flow through so there s no need for gravel or geotextile.
With this design effluent is piped from the septic tank to a shallow underground trench of stone or gravel.
Because these arches interlock they form a continuous drainage area.
The assumption is that the soil under and around the drain field will absorb filter and provide the final treatment of the effluent as it flows through the gravel trenches of.
Less space than traditional septic systems is needed.
Plastic chamber leach field units are high density polyethylene arches.
The gravel stone drainfield is a design that has existed for decades.
Most states require that an alternative septic system be designed by a professional and submitted to the local health department for approval.
As a result they are one of the best septic system alternatives.
Septic mound system design.
A leach field operates similar to a leaching system connected to a septic tank without a tank.
