  • In addition to a septic tank, some septic systems may require a dosing tank or pump tank. These dosing tanks are used to pump the effluent to the absorption area or drain field. Dosing tanks have a sewage effluent pump, a high water alarm as well as control floats.

What is the difference between a septic tank and a dosing tank?

The dosing tank is located after the septic tank or other sewage tank and before the lateral system for effluent distribution. Dosing tank construction requirements are the same as for other sewage tanks. They can be made of concrete, fiberglass or polyethylene but must be durable and watertight.

What is a septic dosing system?

A tank-and-field septic system breaks down domestic sewage and disperses it into the soil; a dosing system adds a pumping station to control flooding or compensate for a site where gravity won’t disperse the wastewater.

What is a dosing pump for a septic system?

A dosing pump with a float (or a series of floats) measures water levels and signals the dosing system to pump water out once wastewater has reached a certain level in the tank. The purpose of the dosing system is to minimize the risks of flooding either the septic tank or the leach field.

What’s a dosing tank?

Definition of dosing tank: a tank in which sewage is collected and later discharged at the rate required by subsequent treatment processes.

How do you tell if your septic tank is full?

How to tell your septic tank is full and needs emptying

  1. Pooling water.
  2. Slow drains.
  3. Odours.
  4. An overly healthy lawn.
  5. Sewer backup.
  6. Gurgling Pipes.
  7. Trouble Flushing.

How often should a septic tank be pumped?

Inspect and Pump Frequently Household septic tanks are typically pumped every three to five years.

How does a dosing chamber work?

A dosing pump draws a measured amount of liquid into its chamber and injects the chemical into a tank or pipe that contains the fluid that is being dosed. It’s powered by an electric motor or an air actuator and has a controller that turns the pump on and off and manages the flow rate.

How much does a dosing tank cost?

They work well in areas with a shallow soil depth. Drip septic systems require more components than a conventional septic system, including a dosing tank and pump, and can cost anywhere from $8,000 to $18,000, depending on their size.

Can you have a septic tank without a leach field?

The waste from most septic tanks flows to a soakaway system or a drainage field. If your septic tank doesn’t have a drainage field or soakaway system, the waste water will instead flow through a sealed pipe and empty straight into a ditch or a local water course.

How does a 2 tank septic system work?

Septic tanks work by allowing waste to separate into three layers: solids, effluent and scum (see illustration above). The solids settle to the bottom, where microorganisms decompose them. The middle layer of effluent exits the tank and travels through underground perforated pipes into the drainage field.

How long should a septic tank pump run?

How long does it take to pump a septic tank? A septic tank between 1,000 – 1,250 gallons in size generally takes around 20-30 minutes to empty. A larger tank (1,500 – 2,000 gallons) will take about twice as long, between 45-60 minutes.

What is dosing system?

A chemical dosing system is a facility for automated injection of reagents into a wastewater network for the control of septicity and odour emissions. These systems are typically used at pump stations, sewer manholes, and rising mains. However, they can be installed any place where odour containment is required.

What is a pressure septic system?

A pressure distribution system is a type of septic system that uses pressure to evenly move wastewater into individual trenches. Pressure distribution systems typically consist of three main components: The septic tank. The dosing pump and pump chamber.

What is a gravity septic system?

Gravity Septic As wastewater enters the septic tank in a gravity system, it pushes effluent out the other end to the drainfield through a network of pipes. This is called “gravity flow” to the drainfield, and these systems don’t need a pump. Then, they can pump your tank when the levels get too high.

How Does a Septic System and Dosing System Work?

A septic system is a system that collects waste from a residence. Featured image courtesy of TheDman via E+/Getty Images When wastewater is discharged from a residence, it is treated to eliminate dangerous agents such as bacteria, viruses, and toxic chemicals before being recycled back into the groundwater system through the soil. An example of a typical septic system is comprised of a septic tank, in which particles are removed from wastewater and a leach field, in which partially treated wastewater is equally transferred to the soil for further treatment.

Tip

Septic systems that use tanks and fields to disperse wastewater into the soil are known as tank-and-field systems. Dosing systems, on the other hand, include a pumping station to regulate floods or compensate for a site where gravity would not disperse the wastewater.

How a Septic System Works

According to the Environmental Protection Agency of the United States, a septic system is essentially a wastewater treatment plant for a single dwelling. It is made up of two parts: a septic tank and what is known as a leach field or soil absorption field, respectively. Your home wastewater is initially sent to the septic tank, which is a cistern made of concrete, plastic, or some other waterproof material, where sediments sink to the bottom and are slowly digested by bacteria as they pass through.

  • Gravity is normally responsible for transporting the liquid part of your wastewater from the tank to the leach area.
  • Wastewater from your home percolates into the soil, releasing pollutants and harmful germs along the way, before merging with the rest of the groundwater in the surrounding region.
  • The word “effluent” refers to the partially treated wastewater that departs a septic tank after it has been treated.
  • A system known as a time-dose control panel is responsible for determining such intervals.
  • Floats (or a set of floats) are used to assess water levels in a tank and to tell the dosing system to start pumping water out whenever the wastewater level reaches a specified level.
  • The dosing system’s primary goal is to reduce the likelihood of flooding in either the septic tank or the leach field.

Dosing System as Emergency Mechanism

It also serves as an emergency switch and alarm system, which is another function of the time-dose control panel. If there are any issues, the dosing system will sound an alarm within the house, which will notify the homeowner of the situation.

Additionally, in the unusual instance of excessive water use, the dosing panel has the capability of overriding the normal period between doses if the septic tank is in risk of overflow.

Dosing System in Separate Tank

As noted by the Department of Health of King County in Washington, in some systems, the dosing system is located outside of the main septic tank. A flood-dosed onsite system is the term used to describe this sort of septic system. Septic systems that use flood-dosed dosing contain a smaller dosing tank located between the main septic tank and the leach field, which serves as an effluent pump. Occasionally, a third, smaller tank known as a “distribution box” is included in the system between the dosing tank and the leach field, which is used to distribute the water.

Advantages of Dosing Septic Systems

A dosing system in combination with a septic system has various benefits over utilizing a separate system. A dosed septic system with an effluent pump, for example, enables homeowners to site a leach field that is uphill from both the septic tank and the residence. There is a possibility that this will be an issue since the septic field requires land with proper drainage, and certain jurisdictions, such as Indiana, place a higher priority on septic field placement than on the site of the home or other structures.

Finally, a dosing system aids in the distribution of effluent equally over the leach field and the preservation of the soil’s health.

Low Pressure Dosing Septic Systems

Using a low-pressure dosing system (LPD), wastewater is treated before being pumped into the soil many times each day. In terms of cost to install and maintain, it is the least expensive of the nonstandard drain fields. The system is typically composed of three components:

  • Water treatment system consisting of a series of tanks or compartmented tanks used to settle out and partially treat wastewater the installation of a pump tank for dosing wastewater into the distribution system
  • The installation of a system for transferring wastewater into the soil

This tank contains a pump that releases wastewater into the drainage system three or four times each day. The distribution system is comprised of a tiny pipe with holes punched into it, which is installed in narrow trenches ranging in width from 6 to 12 inches. The wastewater is discharged into the trenches by the pump. As soon as the wastewater enters the trench, it seeps into the soil. The earth is responsible for the majority of wastewater treatment. Solids and organic debris are removed from wastewater by the filtering action of soil particles.

According to the number of bedrooms in the house as well as the kind of soil where the distribution system will be installed, the sizes of the septic tank, pump tank, and distribution system are determined by these factors:

Advantages of LPD systems

  • The low-pressure dosing system is the least expensive of the nonstandard distribution systems in terms of installation and operation. In clay soils and in soils that are quite shallow, a low-pressure dosing method can be employed. Between the bottom of the trench and the limiting layer or broken soil, one foot of soil must be maintained. It is possible to design and install the system to function on sloping surfaces.

Disadvantages of LPD systems

  • The installation of low-pressure-dosing devices is not possible in soils that get saturated during the wetter months of the year or in soils that are too shallow. A minimum of two feet must be provided between the bottom of the trench and the saturated soil layer or groundwater. Power is required for the functioning and replacement of electrical and mechanical components when the components fail or malfunction.

Keeping a LPD working

  • The septic tanks should be pumped at least once every 2 to 3 years. Once a year, check the pump and alarm system for any problems. Every five years, flush the distribution lines to eliminate silt that has accumulated in the lines.

Types of Septic Systems

Septic system design and size can differ significantly from one neighborhood to the next, as well as throughout the country, due to a variety of variables. Household size, soil type, slope of the site, lot size, closeness to sensitive water bodies, weather conditions, and even municipal ordinances are all considerations to take into consideration.

The following are 10 of the most often encountered septic system configurations. It should be noted that this is not an exhaustive list; there are several additional types of septic systems.

  • Septic Tank, Conventional System, Chamber System, Drip Distribution System, Aerobic Treatment Unit, Mound Systems, Recirculating Sand Filter System, Evapotranspiration System, Constructed Wetland System, Cluster / Community System, etc.

Septic Tank

This tank is underground and waterproof, and it was designed and built specifically for receiving and partially treating raw home sanitary wastewater. Generally speaking, heavy materials settle at or near the bottom of the tank, whereas greases and lighter solids float to the surface. The sediments are retained in the tank, while the wastewater is sent to the drainfield for further treatment and dispersion once it has been treated.

Conventional System

Septic tanks and trench or bed subsurface wastewater infiltration systems are two types of decentralized wastewater treatment systems (drainfield). When it comes to single-family homes and small businesses, a traditional septic system is the most common type of system. For decades, people have used a gravel/stone drainfield as a method of water drainage. The term is derived from the process of constructing the drainfield. A short underground trench made of stone or gravel collects wastewater from the septic tank in this configuration, which is commonly used.

Effluent filters through the stone and is further cleaned by microorganisms once it reaches the soil below the gravel/stone trench, which is located below the trench.

Chamber System

Septic tanks and subsurface wastewater infiltration systems are two types of decentralized wastewater treatment systems that can be used (drainfield). When it comes to single-family homes and small businesses, a traditional septic system is the most common. For decades, people have used a gravel/stone drainfield as a method of removing water. ‘Drainfield’ is an abbreviation for the drainfield that was built. A short underground trench made of stone or gravel collects wastewater from the septic tank in this configuration.

When wastewater passes through the stone, it is further cleaned by bacteria until it reaches the soil under the gravel/stone trench.

Drip Distribution System

An effluent dispersal system such as the drip distribution system may be employed in a variety of drainfield configurations and is very versatile. In comparison to other distribution systems, the drip distribution system does not require a vast mound of dirt because the drip laterals are only placed into the top 6 to 12 inches of soil. In addition to requiring a big dosage tank after the sewage treatment plant to handle scheduled dose delivery of wastewater to drip absorption areas, the drip distribution system has one major disadvantage: it is more expensive.

This method necessitates the use of additional components, such as electrical power, which results in a rise in costs as well as higher maintenance.

Aerobic Treatment Unit

An effluent dispersal system such as the drip distribution system may be employed in a variety of drainfield configurations and is quite inexpensive. In comparison to other distribution systems, the drip distribution system does not require a significant mound of dirt since the drip laterals are placed inside the top 6 to 12 inches of soil. In addition to requiring a big dosage tank after the sewage treatment plant to handle scheduled dose delivery of wastewater to drip absorption areas, the drip distribution system has one major disadvantage: it is more expensive than other wastewater treatment systems.

Mound Systems

Using mound systems in regions with short soil depth, high groundwater levels, or shallow bedrock might be a good alternative. A drainfield trench has been dug through the sand mound that was erected. The effluent from the septic tank runs into a pump chamber, where it is pumped to the mound in the amounts recommended. During its release to the trench, the effluent filters through the sand and is dispersed into the native soil, where it continues to be treated. However, while mound systems can be an effective solution for some soil conditions, they demand a significant amount of land and require regular care.

Recirculating Sand Filter System

Sand filter systems can be built either above or below ground, depending on the use. The effluent is discharged from the septic tank into a pump compartment. Afterwards, it is pushed into the sand filter. The sand filter is often made of PVC or a concrete box that is filled with a sand-like substance. The effluent is pushed through the pipes at the top of the filter under low pressure to the drain. As the effluent exits the pipelines, it is treated as it passes through the sand filtering system.

However, sand filters are more costly than a standard septic system because they provide a higher level of nutrient treatment and are thus better suited for areas with high water tables or that are adjacent to bodies of water.

Evapotranspiration System

Evaporative cooling systems feature drainfields that are one-of-a-kind. It is necessary to line the drainfield at the base of the evapotranspiration system with a waterproof material. Following the entry of the effluent into the drainfield, it evaporates into the atmosphere. At the same time, the sewage never filters into the soil and never enters groundwater, unlike other septic system designs. It is only in particular climatic circumstances that evapotranspiration systems are effective. The environment must be desert, with plenty of heat and sunshine, and no precipitation.

Constructed Wetland System

Construction of a manufactured wetland is intended to simulate the treatment processes that occur in natural wetland areas. Wastewater goes from the septic tank and into the wetland cell, where it is treated. Afterwards, the wastewater goes into the media, where it is cleaned by microorganisms, plants, and other media that eliminate pathogens and nutrients. Typically, a wetland cell is constructed with an impermeable liner, gravel and sand fill, and the necessary wetland plants, all of which must be capable of withstanding the constant saturation of the surrounding environment.

The operation of a wetland system can be accomplished by either gravity flow or pressure distribution. As wastewater travels through the wetland, it may escape the wetland and flow onto a drainfield, where it will undergo more wastewater treatment before being absorbed into the soil by bacteria.

Cluster / Community System

Construction of a manmade wetland is designed to imitate the treatment processes that occur naturally in wetland areas. Wastewater is discharged from the septic tank into the wetland cell. Afterwards, the wastewater goes into the media, where it is cleaned by microorganisms, plants, and other media, which remove pathogens and nutrients. The wetland cell is normally comprised of an impermeable liner, gravel and sand fill, and the required wetland plants, all of which must be able to thrive in a constantly flooded environment in order to function properly.

In other cases, wastewater may depart the wetland and flow onto a drainfield, where it will be treated further before being absorbed into the soil.

Tank Types Demystified

Get articles, news, and videos about Onsite Systems delivered directly to your email! Now is the time to sign up. Plus, there are Onsite Systems. Receive Notifications When it comes to onsite systems, I get a lot of inquiries concerning the many names that are used to identify the sewagetanks. In order to address this issue, the Consortium of Institutes for Decentralized Wastewater Treatment created a glossary of words. Components of onsite systems have varied names depending on the location in which a contractor works, but it was discovered during talks that the functions were the same everywhere.

  1. The two types of onsite sewage tanks are generally classified as follows: treatment tanks and dosing tanks.
  2. Solids separation, decomposition, and storage are the primary functions of treatment tanks.
  3. The amount of time that the effluent is allowed to remain in the tank is referred to as detention time, and it is crucial to the separation of solids.
  4. Inlet baffles and other devices help to promote separation by ensuring that effluent travels a longer distance through the tank during the separation process.

TREATMENT TANKS

The septic tank is the one with which we are most familiar. When it receives raw sewage from a residence or other commercial building, it separates the settleable and floating solids from the liquid, breaks down the organic material by anaerobic digestion (which means without the presence of oxygen), stores the solids, and allows a clarified effluent to move out of the tank and into a soil dispersal area for further treatment. A baffle at the tank’s outflow keeps the partially digested particles at the bottom of the tank, while the floating solids – such as fats, oils, and grease – are kept at the top of the tank by the baffle.

  1. Septic tanks are typically designed to hold enough water for two days of detention.
  2. They accept the waste stream generated in a culinary setting.
  3. Grease traps are intended to hold these substances in place until they can be removed.
  4. “What exactly is a garbage tank?” is a question I am frequently asked.
  5. Trash tanks are tanks or sections of tanks that are situated right before of an aerobic treatment unit and are used for garbage disposal (ATU).
  6. The maker of the ATU determines the size and, to a great extent, the function of the device.
  7. It is mandatory in certain areas to have a septic tank in front of the garbage tank.
  8. In this case, the septic tank is fed with a combination of raw sewage and recirculated effluent in order to increase nitrogen removal efficiency.

Septic tanks, surge storage tanks, pump tanks, and recirculating tanks can all be found in one place as part of the processing tank configuration. A processing tank, on the other hand, is frequently installed after a septic tank.

DOSING TANKS

Our company also deals with dosing tanks, which are divided into four basic categories. These include pump tanks, siphon tanks, flow equalization tanks, and recirculation tanks. A dosing tank is a tank or a compartment inside a tank that stores effluent and is equipped with a pump or siphon that transfers the effluent to another portion of the treatment system once it has been stored. Dosingtanks are sized in accordance with the dosage schedule that is necessary. For a demand dosed system, this implies that the tank’s capacity must be sufficient to accommodate the volume necessary to keep the pump submerged, the dose volume, an alarm activation volume, and any additional reserve volume required above the alert.

  1. In order to hold the average daily flow for the system while it is being given in scheduled dosages to the final soil distribution region, the capacity must be sufficient.
  2. A flow equalization tank is a form of timed dosetank that is more specialized.
  3. Thus, more consistent effluent quality is achieved, as well as increased treatment efficiency of the subsequent component.
  4. If two or more pumps are employed, it is possible that a reserve volume will not be included.
  5. These sorts of designs are useful in situations when flow rates fluctuate significantly from day to day.
  6. The recirculation tank, which was previously addressed as part of the processing tank, is the final form of dosing tank.

» Understanding the Flout® Dosing System for Septic Fields

In contrast to other methods of administering intermittent dosing to gravity fed and pressurized septic fields, the FLOUT® Dosing System is a simple, self-contained, and trouble-free system. Designed for ease of installation, Premier FLOUT® Dosing Tanks are totally pre-assembled, dosage calibrated, and ready for use. Sites where the distribution field may be placed at a lower elevation than the septic system discharge offer the possibility to eliminate the expense and complication of pumping the water to the distribution field.

When it comes to pumped systems, engineering calculations may be used to fairly accurately predict performance, and then a pump selection can be made to ensure that the design performance is met.

The FLOUT® system operates under the same principles of fluid dynamics as a conventional system; however, the possibility of air entrapment in the transport pipe from the FLOUT® to the septic field will reduce flow rate and residual head when compared to the theoretical maximum for a particular system design.

The flow rate from the FLOUT® is mostly governed by the following factors:

  1. When it comes to administering intermittent dosing to gravity fed and pressure fed septic fields, the FLOUT® Dosing System is a straightforward, self-contained, and trouble-free solution. Premier FLOUT® Dosing Tanks are totally pre-assembled, dosage calibrated, and ready for installation when you buy them from Premier FLOUT. When the distribution field can be placed at a lower elevation than the septic system output, it is possible to eliminate the expense and complication of pumping the water to the distribution field. This reduces the amount of standby volume, pumps, wiring, controls, installation, and maintenance required to operate the system effectively. Using engineering calculations, it is possible to predict the performance of pumped systems with reasonable accuracy. Then, a pump selection may be made to achieve the design performance. It is assumed that the entire system will be filled with water for these calculations. When it comes to the FLOUT® system, the same fluid dynamics principles apply as they do for any other system
  2. However, the possibility of air entrapment in the transport pipe from FLOUT® to septic field will reduce flow rate and residual head when compared to the theoretical maximum for a given design. When using the FLOUT®, the following factors influence the flow rate:

When the field resistance is strong (due to a narrow field), the squirt height will increase, resulting in a reduced flow rate and a bigger residual head. The squirt height will decrease in the opposite direction if the field resistance is low (big field), which will result in a faster flow rate and a smaller residual head. When dealing with wider fields, a double Flout® should be considered. Several tests have been carried out by Premier Plastics in order to better understand the interaction between effluent and air in a transport pipe (i.e.

  1. Because of the increased squirt height when field resistance is high (small field), the flow velocity is reduced and the residual head is increased. However, when the field resistance is low (big field), the squirt height will decrease, which will lead to increased flow rate and reduced residual head. If you have a bigger field, a double Flout® should be considered. Several tests have been carried out by Premier Plastics in order to better understand the interaction between effluent and air in a transport pipe (i.e. water wants to go down, air wants to go up), where either water flow down or air flow up could be the dominant force, or the two forces could be equal and antagonistic at times. Using clear acrylic tubing, researchers were able to examine air behavior. Twenty to one hundred and twenty-four orifices of 1/8″ and 3/16″ diameters were tested. Tests were conducted with an average total static head of 142″ and 42″. On our website, you may request detailed findings for specific settings, and you will receive them. Engineers and designers may get insight into the real dynamics of these systems as a result of the data we have gathered, allowing them to feel more confident in their decision to use FLOUT® Dosing Systems.

OBSERVATIONS OF THE RIVER’S FLOW

A more horizontal line shows that some air is exiting during the course of the cycle, resulting in an increase in the remaining head. The decreasing head in the tank is countered by an increase in residual head in the tank. ­ It is possible that substantial air is escaping throughout the cycle, as shown by an increased flow rate throughout the cycle. ­ This implies that the air has been entirely purged or has achieved a stable state at some point throughout the cycle, and that the flow rate then drops in tandem with the decreasing head in the tank.

Please keep in mind that the measurements of flow rate and residual head were collected at the point of entry into the (simulated) field (see below). The transparent acrylic piping utilized for the transport pipe was 2″, 3″, and 4″ in diameter. THE IMPACT OF TRANSPORT PIPE SIZE IN GENERAL

  1. A smaller diameter pipe (2″) will fully flood more rapidly, allowing the vertical head to be utilized to its full potential in propelling the flow to the field
  2. And It is possible that air and effluent will continue in a turbulent interaction as equally opposed forces throughout the cycle due to the usage of a medium diameter pipe (3″). In various portions of the pipe, the flow may vary between entirely flooded and channel flow at different times. Despite the fact that this scenario may result in the greatest amount of possible aeration of effluent, the squirt height will be limited. It is possible to increase the squirt height by venting the transport line towards the top of the slope, which will discharge the trapped air and result in a higher squirt height. A large diameter pipe (4″) will result in more stable flow – channel flow (non-flooded) at the top end of the transport pipe, and completely flooded flow at the bottom part of the transport pipe, which would provide the driving head into the field – than a smaller diameter pipe. No head benefit can be obtained from non-flooded sections of pipe
  3. Nevertheless, a combination of a larger pipe diameter at the top end of the transport pipe and a smaller pipe diameter at the bottom end will guarantee that the necessary residual head for the desired squirt height is attained. Managing what may be perceived as excessive squirt height in a system with a significant vertical drop can be accomplished by ensuring that all flow in the upper section of the transport pipe is conducted in channel mode with stable separation of effluent and air, thereby limiting the buildup of residual head at the field. When the cycle was first started, the maximum possible flow rate (i.e., with no trapped air) was established by filling the transport pipe with water prior to commencing the cycle. In comparison with the regular cycle, these data show how much of an impact air in the transport pipe has on the outcomes. (Refer to the Tables.)

THE FLOW RATE WITH THE LEAST VERTICAL DROP It is critical to design systems in which completely flooded flow is required in order to maintain the appropriate squirt height at the start of the discharge cycle to guarantee that air is purged as rapidly as possible. It is anticipated that trapped air will have a pressure equal to or greater than that created by the head in the Dosing tank, hence limiting flow rate. In our testing, we discovered that a 1″ vent connection put a few feet down the sloping portion of pipe will help to expel air that might otherwise become trapped.

It is important to note that venting the line to atmosphere decreases the “back pressure” on the tank, allowing trapped air to escape and the transport pipe to flood rapidly.

Type C, in which the field is level with the septic tank, as illustrated in our newflyer (click here).

Small Septic & Pump Tanks

LOW VERTICAL DROP AND HIGH Flow Rates It is critical to design systems in which completely flooded flow is required in order to maintain the ideal squirt height at the start of the discharge cycle so that air is purged promptly at the beginning of the discharge cycle. Trapped air will be at the pressure created by the head in the Dosing tank and will serve to restrict the pace of the flow of the liquid through the tank. In our testing, we discovered that a 1″ vent connection put a few feet down the sloping portion of pipe will help to expel air that would otherwise be trapped.

In addition, allowing trapped air to leave and the transport pipe to flood fast, venting the line to the atmosphere minimizes ‘back pressure’ on the tank.

Does Your Septic System Require A New Pump?

A septic tank’s waste and sewage are evacuated from it and discharged into a drain field, either by gravity or with the assistance of a septic system lift pump. In most cases, a septic pump is not required if the waste can flow at a rate of at least two feet per second through the system using gravity alone. Pumps are typically required for septic tanks that are located lower than the drain field and for which gravity is unable to transport and/or force the effluent out of the tank due to its location.

Know If Your System Uses A Septic Effluent Pump Or Septic Grinder Pump

It is possible to pump waste and sewage out of a septic tank and directly onto a drain field, either by gravity or with the aid of an automatic septic system lift pump. If the waste can be moved at a pace of at least two feet per second by gravity alone, a septic pump is often not required.

If your septic tank is located lower than your drain field and gravity is unable to transport or push the effluent out of your tank, you will most likely need a pump installed in your system.

How Septic Pumps Work

A septic pump is a sort of submersible pump that is installed in either the last chamber of the septic tank or in a separate chamber outside the main tank of the system. As waste builds up in the chamber, it activates a float switch, which then activates the septic pump. After that, waste is forced up the outflow pipe and into the drain field by an impeller. Installing a septic tank pump alarm is an excellent strategy to avoid having to clean out your septic tank on a regular basis. One of our professionals will connect the float switch to an alarm panel, which will sound if the pump fails for any reason during the installation.

This alarm will ring and notify you if there is a sewage backup in your home.

Maintenance For A Septic Pump

The upkeep of a septic pump goes hand in hand with the upkeep of a septic system in its whole. Never drain or flush any of the following common home objects to avoid the need for emergency septic service and to ensure the pump’s long-term functionality:

  • Baby wipes
  • Cat litter
  • Fats, oils, and/or grease produced by or utilized in the preparation of meals
  • Dental floss
  • Personal hygiene products
  • And Q-tips or other cotton swabs are all recommended.

In addition, avoid using the garbage disposal because this can cause the septic tank to fill up more rapidly and force water into the tank, among other things. If there is an excessive amount of water entering the septic system, it can cause sediments to enter the septic pump, resulting in a probable blockage in either the pump or the drain field. If or when this occurs, contact Jones PlumbingSeptic Tank Service for prompt and dependable septic tank repairs.

Common Septic Pump Issues

Even with proper maintenance, a septic pump can develop a variety of problems over time, including the following:

Noise Or No Noise

There are occasions when it is possible to hear the septic pump operating within the chamber itself. Do not hesitate to contact us for septic service if it appears that the pump is having difficulty or is failing to transport waste effectively.

Leaking Into The Septic Tank

The septic pump is equipped with a check valve, which provides a pressure gradient in order to keep the waste flowing through the pump and into the drainage system. Whenever the valve wears down or breaks, waste is forced back into the septic tank, causing the tank to overflow and back up into the pipes.

Faulty Float

Floats can become stuck open or closed, or they might become damaged as a result of material entering the septic tank. Depending on the extent of the damage, a professional from Jones PlumbingSeptic Tank Service may be able to remove the debris or may need to replace the float entirely.

Burnt Out Motor

If the motor within the septic pump burns out or fails, the pump will be unable to transfer waste, even if the energy is still being supplied to the device, since the waste would be trapped. In most cases, replacing the pump will address the problem.

Onsite Wastewater Treatment Systems: Low-Pressure Dosing System

Our work has a positive impact on the lives of Texans as well as the state’s economy. View Economic Impacts» for further information. HomeLibrary WaterOnsite Wastewater Treatment Systems: Dosing System with Low-Pressure Water Contributed by Bruce Lesikar, Extension Agricultural Engineering Specialist for the Texas A & M University System. A low-pressure dosing system purifies wastewater before pumping it into the soil on a regular basis at a low pressure. In terms of cost to install and maintain, it is the least expensive of the nonstandard drain fields.

  1. Every three or four hours, the pump tank discharges wastewater into the distribution system, which is housed in a separate building.
  2. The wastewater is discharged into the trenches by the pump.
  3. The earth is responsible for the majority of wastewater treatment.
  4. Microbes in the soil break down the sediments and destroy the bacteria and pathogens in the waste water, which helps to keep the environment clean.

Advantages

For both installation and operation, the low-pressure dosing system is the least expensive of the nonstandard distribution systems available on the market today. In clay soils and relatively shallow soils, a low-pressure dosing device can be utilized to apply fertilizer. It is necessary to keep one foot of dirt between the bottom of the trench and the restrictive layer or cracked soil. It is possible to design and install the system to function on sloping surfaces.

Disadvantages

Because low-pressure dosing systems cannot be put in soils that become saturated during rainy seasons or in shallow soils, low-pressure dosing systems are not recommended.

Between the bottom of the trench and the saturated soil layer or groundwater, two feet of space must be maintained. Electricity is required for the operation of electrical and mechanical components as well as for their replacement when they fail.

How to keep it working

  • Installation of low-pressure dosing systems in soils that get saturated during wet seasons of the year, as well as shallow soils, is not possible. Between the bottom of the trench and the saturated soil layer or groundwater, a minimum of two feet must be maintained. Power is required for the functioning and replacement of electrical and mechanical components when they malfunction.

Estimated costs

Based on a three-year tank pumpout plan, a five-year pump replacement schedule, and little power demand, annual maintenance expenditures are around $125 per year. The cost of installation varies from $3,000 to $10,000, depending on the soil type, the size of the house, and other considerations.

Septic Solutions – Installation

With a 3-year tank pumpout plan, a 5-year pump replacement schedule, and a tiny amount of power consumption, annual maintenance expenditures are around $125. Depending on the soil type, the size of the house, and other variables, installation expenses might range from $3,000 to $10,000. Is it necessary for you to contact an expert because you have a query or concern? Inquire with the appropriate county office.

Conventional Systems

Traditional septic systems may be divided into two categories: those that employ gravel in the drainfield and those that use some sort of chamber system. The earlier stylegravelled system, as the name implies, comprises a layer of gravel in the drainfield. In the course of the building, a drainfield ditch is dug that is 1 to 3 feet below ground level. Its length is decided by the amount of effluent that will be discharged into the system from the house or rural office, as well as the soil’s ability to absorb water during the winter months.

  1. In order to prevent backfill dirt from filtering between the rocks and decreasing the field’s ability to absorb water, more gravel is poured around and over the pipe.
  2. Despite the fact that some waste is treated in septic tanks by bacteria that live within the tank, the majority of waste treatment happens when wastewater discharged from the tank enters the drainfield and is filtered through the gravel and soil below.
  3. These organisms grow and produce a layer known as a biomat, which sits on top of the soil layer and protects it.
  4. The presence of these organisms helps to maintain the biomat from getting so thick that it prevents wastewater from reaching the soil below while the drainfield is in equilibrium.
  5. Because gravel is used to filter the effluent, it instantly reduces the capacity of the effluent to reach soil, which is where the majority of the filtation takes place.
  6. Apart from that, even when competent contractors utilize solely cleaned gravel, a certain quantity of particles is certain to stay and eventually reach the soil level, further lowering the possibility of filtering.
  7. This can happen when the water table rises over the drain pipe, essentially cutting off the drainfield’s capacity to release water completely.

After that, there’s the chance of drainfield overflow, which can occur when there are more visitors in the house for extended periods of time or when taps or toilets are left running for extended periods of time.

Some of the disadvantages of gravelled systems are alleviated by gravelless conventional systems.

Typically, these chambers are made of molded high-density plastic and are available in lengths ranging from 10′ to 12′ feet.

Because we have discovered that the Infiltrator chamber system is the most successful when used in North Texas soils, Septic Solutions of Texas solely employs the Infiltrator chamber system.

When the system is put into service, waste water is transported via pipe from the septic tank to the chamber run, where it flows directly against the earth.

This is particularly effective in areas where the water table might rise near to the surface, as well as in situations where there is a brief rush in demand as a consequence of additional visitors.

Obviously, shock loading for extended periods of time will have a negative impact on the biomat since oxygen will not be accessible to parasites during these durations.

Low-Pressure Dose Systems

Low-pressure dosing systems (also known as low-pressure pipe systems) may be a viable option in situations when soil and topographical factors do not allow for the installation of a typical septic system, such as urban areas. Particularly relevant in situations where geography dictates that the drainfield be positioned up-hill from the septic tanks or where there is uneven terrain that would otherwise prevent the installation of a traditional system. Low-Pressure Dose Systems (LPDs) are designed to function in the following ways: A pumping chamber is placed in addition to the typical septic tank, which is a type of holding tank.

  • The drainfield for an LPD application is made up of tiny perforated pipes laid in shallow, gravel-lined trenches that range in depth from 10″ to 18″ and in width from 12″ to 18″.
  • After then, the field is allowed to drain.
  • Shallow placement also encourages evapo-transpiration, which is the process by which evaporation and grass and other shallow-rooted vegetation serve to remove waste.
  • Alarms will be activated if there is a significant increase in flow.
  • Whenever a drainfield is not placed on a slope, the system will be constructed in such a manner that effluent does not exit the pumping chamber after the pump has been switched off.
  • Furthermore, because of the employment of a low-pressure pump, the whole drainfield will be utilized in a consistent manner.
  • However, there are several disadvantages to LPDs, including the possibility of root penetration and the blockage of drain holes by particles that leave the pumping chamber.

Finally, LPDs must be serviced on a regular basis. Electricity, a pump, and a smaller drainfield all raise the likelihood of system failure. As a result, most regulatory agencies now mandate septic system inspections by qualified septic specialists on a yearly or semi-annual basis.

Evapotranspiration Systems

The use of Evapotraspiration Systems (ETs) is often only practicable in arid and semi-arid environments. To put it simply, we are interested in climates where evaporation surpasses rainfall by at least 24 inches per year. The EP system is based on the natural evaporation of wastewater via a sand barrier, as well as the simultaneous transpiration of water through the leaves of plants and grasses grown above the drainfield, to remove pollutants. In contrast to the methods mentioned above, an ET system consists of a trench lined with an impervious barrier that drains to a collection basin below ground.

  • Above the gravel is a layer of sand that is raised above the level of the surrounding ground.
  • Naturally, this sort of system performs best during the spring, summer, and fall seasons, when heat and sunlight combine to deliver the most effective wastewater treatment.
  • Applications in places with short soil depths and impermeable rock or hardpanlayers beneath the surface are recommended.
  • Additionally, after the system has been in operation for an extended length of time, there is the possibility of salt accumulation near the surface.
  • This is essentially the same system as an ET system, with the difference that the drainfield is not enclosed in this configuration.
  • Generally speaking, wastewater must be able to flow through at least 2 to 4 feet of unsaturated soil before reaching the ground water table in order to be effective.
  • In North Texas, most permitting authorities demand the construction of two fields, with the owner physically switching the wastewater flow between the fields once a month, as well as the building of two fields.

Aerobic Wastewater Treatment Systems

When it comes to evapotranspiration systems, they are often only practicable in arid and semi-arid environments. To put it another way, we’re seeking for regions where evaporation surpasses rainfall by at least 24 inches per year. Rather than using chemicals, the EP system relies on natural evaporation of wastewater via a sand barrier, as well as concurrent transpiration of water through the leaves of plants and grasses grown above the drainfield. In contrast to the systems mentioned above, an ET system consists of a trench lined with an impervious barrier that drains into a collection basin below the surface.

In addition to the gravel, there is also a layer of sand that is elevated above the ground level.

Naturally, this sort of system performs best during the spring, summer, and autumn seasons, when heat and sunlight combine to deliver the most effective wastewater treatment.

Applications in places with short soil depths and impermeable rock or hardpanlayers beneath the surface are beneficial.

Additionally, after the system has been in operation for an extended length of time, there is the possibility of salt accumulation near the surface.

A drainfield that has not been sealed is used in this system, which is nearly identical to an ET system.

To reach the ground water table, wastewater must be able to pass through at least 2 to 4 feet of unsaturated soil before it is considered to be treated.

When building a wastewater treatment plant in North Texas, the majority of permitting authorities demand that two fields be constructed, with the owner manually switching the wastewater flow between fields once a month.

However, despite the fact that this system has no moving components, no electricity requirement, and requires less regular maintenance than LPD or Aerobic Systems, it requires a greater amount of land for the evapotranspiration field.
