Pressurised Polishing Filters, also known as a Low Pressure Pipe System (LPP) is a very common method of distributing treated effluent from a sewage treatment system into the soil. The effluent is pumped from the Streamline BAF to a either a splitter valve or a manifold which in turn distributes the effluent trough a number of 32mm laterals to disperse the effluent evenly over the bed.

A Trench Soil Polishing Filter (TSP) is a more traditional method of distributing effluent from a septic tank or sewage treatment system.  This is option is more ideal for sites with a topography that favors a gravity outlet from the septic tank or sewage treatment system.

Drip Irrigation Systems can be used as an alternative method of distributing effluent into poorly draining soil. A drip system has the advantage of working well on sites with limited soakage as the effluent is evenly distributed across a large network  of high pressure pipes with small emitters that let the effluent out at a controlled pace.

It should be noted that Drip Irrigation Systems have a number of downsides such as:

  • The requirement for a medium to large footprint to install the system
  • Regular maintenance is required to clean filters and backwash manual systems. (Fully automatic systems are more expensive to install but are highly recommended)
  • Any site intended for drip irrigation must be protected from vehicular traffic before, during and after installation to minimise damage to mechanical components and the soil as the pipes are generally installed at a depth of 150mm to 200mm below ground level.

Tertiary Sand Polishing Filters treat the waste water from the Streamline BAF system to a higher standard prior to final discharge into the soil and are ideal for restricted sites as they have a small footprint. A sand polishing filter is generally the most viable option on sites with limited available area and/or sites with poor soakage as the effluent discharged from a sand polishing filter does not form a biomat or sludge layer which can impede the rate of soakage into the ground.

Puraflo Tertiary Modules use peat fibre to treat the waste water from the Streamline BAF system to a high standard prior to final discharge into the soil and are ideal for restricted sites as they have a small footprint. Puraflo modules are generally a suitable option on sites with limited available area and/or sites with poor soakage as the effluent discharged from a sand polishing filter does not form a biomat or sludge layer which can impede the rate of soakage into the ground.

SteamPod Tertiary Modules are highly effective way to treat the waste water from the Streamline BAF system to a very high standard prior to final discharge into the soil and are ideal for restricted sites as they have a small footprint. StreamPod modules are generally a suitable option on sites with limited available area and/or sites with poor soakage. The StreamPods are delivered and placed by truck mounted crane.
