Septic Tank Leach Field Alternatives

The gravel stone drainfield is a design that has existed for decades.

Septic tank leach field alternatives.

Here is an explanation of a sand filter septic system. Plastic leach field chamber. Plastic chamber leach field. Most states require that an alternative septic system be designed by a professional and submitted to the local health department for approval.

A leach field operates similar to a leaching system connected to a septic tank without a tank. The effluent flows from the house to perforated pipes within a layer of gravel filled trenches. Less space than traditional septic systems is needed. A conventional septic system is typically installed at a single family home or small business.

With this design effluent is piped from the septic tank to a shallow underground trench of stone or gravel. 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. Because these arches interlock they form a continuous drainage area.

The effluent seeps into the gravel from the perforated pipes and then the soil. Plastic chamber leach field units are high density polyethylene arches. If you prefer. Septic mound system design.

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. As a result they are one of the best septic system alternatives.
