Plastic leach field chamber.
Septic tank leach field alternatives.
Septic mound system design.
The effluent seeps into the gravel from the perforated pipes and then the soil.
If you prefer.
Septic system alternative designs refers to any onsite wastewater disposal method other than the widely used conventional septic tank and leach field.
A conventional septic system is typically installed at a single family home or small business.
The gravel stone drainfield is a design that has existed for decades.
The effluent flows from the house to perforated pipes within a layer of gravel filled trenches.
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.
Because these arches interlock they form a continuous drainage area.
With this design effluent is piped from the septic tank to a shallow underground trench of stone or gravel.
The chambers create an empty space for effluent to flow through so there s no need for gravel or geotextile.
Plastic chamber leach field units are high density polyethylene arches.
Plastic chamber leach field.
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.
Here is an explanation of a sand filter septic system.
A leach field operates similar to a leaching system connected to a septic tank without a tank.
Less space than traditional septic systems is needed.
Most states require that an alternative septic system be designed by a professional and submitted to the local health department for approval.
