Pressurized Septic System

Pressure distribution is a technique for uniformly applying effluent throughout an absorption region. An infiltrative surface receives about the same amount of radiation per square foot. The pace of dispersion is slower than the soil or media’s ability to receive it.

The advantage of pressure distribution is that it improves treatment efficacy in soil-based or alternative (mound, and packed bed) on-site systems by preserving vertical unsaturated flow. The degree of blockage is lowered with finer-textured soils or media.

A pressure distribution system is a form of septic system that distributes wastewater equally into individual trenches using pressure. There are three basic components in most pressure distribution systems.

  • The septic tank, to be precise.
  • The pump chamber and the dosing pump.
  • The drainfield and the region where it will be replaced.

Pressure distribution is most commonly employed in situations when it is desirable or necessary to:

  • Ensure that wastewater is applied uniformly throughout a soil absorption field or on the infiltrative surface of pressured alternative systems, such as mound or packed bed systems.
  • Effluent should be treated and dispersed higher in the soil profile.
  • Extend the life of a soil absorption field, a mound, or a packed bed system by improving treatment performance.

Why Use Pressure Distribution Septic Systems?

Why Use Pressure Distribution Septic Systems?

When permeable soils are shallow and uniform distribution of wastewater is needed for optimal treatment, pressure distribution septic systems are commonly used.

Pressure septic systems not only provide greater effluent treatment but drain fields aren’t always suitable for placement near a dwelling.

A pressurized system is a solution when long distances must be traveled or high heights present gravitational issues.

Gravity is employed to carry wastewater through septic systems and into drain fields in many cases.

In a gravity-fed septic system, wastewater is substantially cleansed in the septic tank prior to running out from the tank then down to the drain field through a system of pipes.

Nevertheless, not all situations favour gravity distribution of wastewater effluent leaving the tank. When gravity-fed systems are unable to complete the task, alternative methods must be utilised. One example is pressure-distributed septic systems.

Gravity Septic System Vs a Pressure Distribution Septic System

A Gravity Septic System Vs a Pressure Distribution Septic System

While gravity can be a very effective technique of spreading wastewater effluent, it is not always feasible or desirable.

Gravity can only be utilised to transport wastewater from the septic tank downslope. Gravity cannot be employed to transfer wastewater effluent to the drainage area for dispersal if the drain field is located upslope from the septic tank.

Because gravity determines where the wastewater will go and how efficiently it will get there, the distribution of wastewater effluent in gravity-fed septic systems is typically localised to a small area because system designers are limited in the area they have available to distribute the wastewater too.

As a result, soils inside the drain field might become oversaturated, resulting in clogging and pooling, as well as groundwater pollution, and eventually reducing the drain field’s lifespan.

Pressure distribution septic systems provide a remedy to the difficulties that are frequently connected with gravity-fed distribution systems.

How Does a Pressure Septic System Work?

  • A pressure distribution septic system, as the name indicates, employs pressure to transport wastewater effluent to the drain field and disperse it equally across the soil in the drainage region.
  • If the drain field is located upslope from the septic tank, a pressure septic system can convey wastewater uphill through pipes before distributing it into the soil in the chosen distribution area. Because pressure septic systems encourage a more uniform dispersion of effluent across the drain field, they can assist minimise oversaturation of the drain field soils.
  • A pressure distribution septic system, like a traditional septic system, will contain a septic tank where particles and fats are removed from the wastewater before it flows out to a dosing tank.
  • Once in the dosing tank, the wastewater effluent is pushed to the drain field, which is made up of a series of perforated PVC pipes with balancing valves that guarantee the wastewater effluent is dispersed equally across the distribution area.
  • The wastewater effluent flows from the drainage pipes and is dumped into the surrounding soils, where it is further treated by naturally existing soil microorganisms.
  • The dosing tank pumps a predetermined amount of effluent into the drain field’s distribution network, ensuring that the drain field is never oversaturated with wastewater.
  • The pressure septic system’s constant dosing guarantees that no area of the drain field receives more effluent than it can drain, extending the drain field’s lifespan.

Pressure Dose Septic System

Pressure Dose Septic System

A pressure dose septic system is quite similar to the pressure systems already discussed in this text. The distinction is that instead of flowing directly into the pipe network with equal distribution through evenly spaced orifices, the effluent is pressurized and routed to a distribution box.

The distribution box subsequently uniformly distributes the effluent dosage over the drain field lateral portions. The lateral portions from the distribution box are frequently significantly bigger in diameter than the lateral sections from a uniform distribution.

Gravity then transports the effluent from the distribution box to the field.

Sewage flows from the house into a septic tank in this setup. Following basic treatment in the tank, wastewater flows into a dosing chamber outfitted with a pump, filter screen, and float control switches.

Throughout the day, specific dosages of wastewater are delivered to the disposal area. This pressurization dosing improves dispersion to the whole disposal field as well as wastewater treatment in the soil.

Clean drain rock or a chamber-type dispersal unit can be used to fill these ditches.

A capping fill is necessary in specific circumstances. This dirt blanket is placed over the disposal field to protect the disposal trenches and alleviate shallow native soils.

Regularly pumping the septic tank (once every 3–4 years is recommended), maintaining the electro-mechanical components, and caring for the soil cover over the disposal field to prevent surface water (storm water) from traversing and/or ponding on top of the system are all part of the pressure dose system’s maintenance operations.

Maintenance is critical to the system’s longevity and should be performed on a regular basis by a qualified specialist.

When Is a Pressure Septic System a Good Option?

A pressure septic system is an excellent choice for delivering effluent to drain fields located upslope from a septic tank, but it is also appropriate in other situations.

A pressure distribution system, for example, can prevent the underlying soils from getting overloaded and the whole drainage system from becoming inundated on sites with a confined layer consisting of subsoils with limited permeability.

A pressure distribution system can handle a wider drain field and ensures that the effluent is dispersed uniformly across the drain field rather than being concentrated in a limited region.

A pressure distribution septic system is also appropriate for drain fields on a slope, where drainage downslope might result in effluent buildup and floods, especially if wastewater is dispersed to tiny concentrated regions surrounding the drain field.

A pressure distribution septic system distributes wastewater effluent uniformly over the dispersion field, boosting absorption rates and minimizing the risk of pooling downslope.

Finally, a pressure distribution system is advised in instances when the drain field will be unusually extensive, due to either the size and design of the septic system or local restrictions (e.g. soil).

Even in smaller drain fields, gravity septic systems fail to disperse wastewater uniformly, and they are insufficient for distributing effluent throughout a larger drain field.

Pressure Septic System Design

Pressure Septic System Design

A timed pressure distribution system allows the daily effluent outflow to be spread out more evenly throughout the day, both in terms of time and area. This relieves the strain on the system at the busiest times of the day, when most homes are online.

More water (early morning and evening), more uniformly distributed flow throughout the day, and adequate time between batch outputs to ensure that the system is neither swamped or overwhelmed and that efficient treatment happens.

When a pressure distribution system is turned on, wastewater is uniformly spread across the whole dispersion network.

Until the biomass develops inside the soil, which slows the rate of flow and assists the treatment process, this alleviates preferential flow that may occur in gravity systems.

Treatment will be impaired if wastewater flows through soils too fast (for example, loose sandy soil).

The flow rate of wastewater may be regulated with a pressure distribution septic system, ensuring that water flows slowly through the soil and is thoroughly treated as it goes through.

The system is constructed in such a manner that the volume of wastewater from the septic tank coming out of each perforation in the distribution pipeline is equal in order to ensure uniform distribution over the drain field.

The diameters of both the pipes in the distribution network and the holes in those pipes must be properly designed to do this; a minimum orifice size of 3.2mm (percent “) diameter is typical.

A conventional pressure septic system, such as a sand mound or shallow trench septic system, is made up of the following main components:

  • Solids are sorted, held, and removed in a septic tank or equivalent pre-treatment chamber.
  • The screen (effluent filter) between the septic tank outflow and the pump chamber prevents particles from clogging the pump and the perforations in the distribution pipes.
  • Between pump cycles and in the case of a malfunction, a pump or syphon tank receives and stores wastewater effluent from the septic tank.
  • Pump to push wastewater through the distribution system under pressure.
  • Pump control box and power supply to make pump operation and distribution timing easier.
  • The main pipeline (force main) (which connects the pump and the manifold) and the manifold that connects to the drain field’s lateral pipes.
  • Cleanouts and monitoring ports are installed at the distal ends of lateral pipes with holes drilled at evenly spaced intervals (orifices) on the inverted side of the pipe.
  • Drain fields are made up of natural soil or other media that aid the biological and physical processes required for proper wastewater treatment.
  • Using washed drain rock or an infiltration system

Pressure Septic System Cost

Although pressure distribution septic systems have numerous advantages over gravity septic systems, they are more expensive.

While the initial cost is slightly higher than that of a gravity distribution system (usually $5,000-57000), it is still less than many other types of septic systems.

Regular maintenance is required for pressure distribution systems, which can drive up costs over time.

Pressure Septic System Maintenance

Pressure Septic System Maintenance

A pressurized distribution system is intended to extend the life of a drain field; nevertheless, they will not last as long as the drain field unless they are properly maintained.

Clogging caused by mineral building or the accumulation of other impurities in the distribution network over time is one of the most serious issues.

The pressurized distribution system will not perform as well as it should if the apertures (orifices) in the dispersal pipes become blocked, and it may eventually fail.

As a result, the lateral distribution pipes must be cleaned and flushed out on a regular basis—typically twice a year, but at the very least once a year. This maintenance task is a little annoying to your system’s general health, but it comes at a cost because it is labor demanding; contact your local maintenance provider for pricing.

If you don’t repair your dispersal pipelines on a regular basis, your system’s performance will deteriorate as the pressurized distribution system becomes ineffective, and you’ll eventually need to replace the complete distribution pipe network.
