Here are some examples of design solutions for different sites.
Septic tank solutions can be divided into gravity systems and pumped.
In a gravity system, as wastewater enters the septic tank, it pushes effluent out the other end, through a network of pipes, to the drainfield. This is gravity flow to the drainfield, and no pump is needed. The heart of a gravity septic system is the septic tank, because a good-quality tank can remove two-thirds or more of the wastewater contaminants.
In a pumping system, effluent is pumped from the septic tank to the drainfield or to an additional treatment unit. This allows the drainfield or additional units to be uphill from the tank. The heart of the system is the filtering pump vault.
Polish Filter Treatment Plants
Filters are largely used to treat and polish the wastewater coming from septic tanks whereby sedimentation already has taken place to remove the most of the solids before being fed to the filter system. It is normally considered to be part of a small treatment facility capable of producing high quality effluent discharge that can be applied for other processes such as irrigation needs and toilet flushing.
