What size septic tank needed for 250 persons in and out?
- Regards Mike Whats the size of septic tank needed for 250 persons in and out? The smallest residential septic tank size permitted by building officials in most communities is 1000 gallons – but your local building or health or plumbing department is, of course, the final legal authority to answer that question.
How often should a 750 gallon septic tank be pumped?
It is recommended that you pump the 750 gallon tank every year and a half. You can stretch it to once every two and a half years if your tank holds 1000 gallons. You need to pump once a year with a 1000-gallon tank if you double your household size.
Is a 750 gallon septic tank big enough?
The larger your home, the larger the septic tank you’re going to need. For instance, a house smaller than 1,500 square feet usually requires a 750 to 1,000-gallon tank. On the other hand, a bigger home of approximately 2,500 square feet will need a bigger tank, more than the 1,000-gallon range.
How often does a 500 gallon holding tank need to be pumped?
But here are some general guidelines: Family of 2, 500-gallon tank – pump every 2.5 years. Family of 3, 1000-gallon tank – pump every 4 years. Family of 5, 1000-gallon tank – pump every 2 years. Family of 5, 1500-gallon tank – pump every 3.5 years.
How long should a septic tank aerator run?
The aerator should run 24/7 nonstop and should not cost more than 10 dollars a month to run. If you electric bill is high something else is causing it or the system is not correctly hooked up.
How do you size an aerobic septic system?
Aerobic units should be large enough to allow enough time for the solids to settle and for the wastewater to be treated. The size of most units range from 300 to 1,500 gallons per day, but local regulations often require that the unit be at least large enough to handle 500 gallons of wastewater per day.
Can I shower if my septic tank is full?
Only the water would get out into the leach field in a proper system unless you run too much water too fast. The thing to do is to run your shower water outside into it’s own drain area, but it may not be allowed where you are. Used to be called gray water system.
What are the signs that your septic tank is full?
Here are some of the most common warning signs that you have a full septic tank:
- Your Drains Are Taking Forever.
- Standing Water Over Your Septic Tank.
- Bad Smells Coming From Your Yard.
- You Hear Gurgling Water.
- You Have A Sewage Backup.
- How often should you empty your septic tank?
How do you tell if your septic tank is full?
How to tell your septic tank is full and needs emptying
- Pooling water.
- Slow drains.
- Odours.
- An overly healthy lawn.
- Sewer backup.
- Gurgling Pipes.
- Trouble Flushing.
What are the dimensions of a 750 gallon concrete septic tank?
750 Gallon Septic Tank – Single Compartment. 60”D x 51”H x 92”L.
How often should you pump your septic tank?
Inspect and Pump Frequently The average household septic system should be inspected at least every three years by a septic service professional. Household septic tanks are typically pumped every three to five years.
How often should an 800 gallon septic tank be pumped?
How often should you have your septic tank pumped? You should clean your septic tank every 2-5 years depending on how many bedrooms you have in your house as well as the local regulations.
Can a septic tank never be pumped?
What Are the Consequences of Not Pumping Your Tank? If the tank is not pumped, the solids will build up in the tank and the holding capacity of the tank will be diminished. Eventually, the solids will reach the pipe that feeds into the drain field, causing a clog. Waste water backing up into the house.
What size holding tank do I need?
For large properties with significant landscaping and a large home we recommend a minimum of 10,000 gallons. For smaller properties and homes that don’t have to worry about fire considerations, 2500-3000 gallons is a common tank tank that will give you plenty of water for daily needs.

SEPAERATOR® VALUE PACKAGE DETAILS
The SepAeratorTM is equipped with only the highest-quality air pumps, which have been developed and tested to provide trouble-free operation for many years. A high-quality and high-performance septic air pump, the Hiblow air pumps have shown to be extremely reliable. The Hiblow air pump included in the SepAeratorTM Premium package has a flow rate of 3.7 cfm and is capable of treating up to 500 gallons of wastewater per day or a septic tank with a capacity of up to 2000 gallons. This air pump will need around $4 to $8 in electricity each month to run.
The diaphragms in the air pump have an average life span of 5 to 7 years on average.
Even if you elect to replace the diaphragms in your unit when they fail, a pump will last you around 10 to 12 years.
Patented Wonderfuser™ Assembly
The Wonderfuser diffuser assembly from Septic Solutions® is a one-of-a-kind design that is exclusively available in the SepAeratorTM packages. In addition to being maintenance-free, the Wonderfuser is extremely successful at not only transferring oxygen into wastewater but also breaking down big solids into little pieces to make digestion more efficient. The Wonderfuser will be lowered into your septic tank and placed on the bottom of the intake side of the tank. The base of the diffuser assembly weights 13 pounds in order to ensure that it will rest solidly on the ground.
- The SepAeratorTM Wonderfuser delivers oxygen into a septic tank roughly 10 inches above the bottom of the tank through a series of 48 orifices that are oriented downward at approximately 35 degrees from top to bottom from the top to the bottom.
- In the Wonderfuser, there is a deflection region 15 inches from the bottom, which allows all rising air bubbles to be deflected outward and around the diffuser in a 360-degree circle.
- Second, the deflector causes the tank to roll as a result of the rolling movement.
- The SepAeratorTM Wonderfuser is unique in that it uses a deflected rolling movement to break down most solids that enter the tank into extremely small particles within 30 seconds.
- Whenever those solids are swiftly broken down into little particles that are constantly moving about inside the tank, aerobic bacteria that are created as a result of adequate oxygen being delivered into the tank may attach themselves to those small particles very fast and readily.
Because these aerobic bacteria can detect and consume many smaller and moving particles very fast, the quality of the effluent can be significantly improved overall.
Heavy Duty Spa-Flex Airline
An extremely high grade material, which is both robust and flexible, is used to construct the spa-flex air line. Because of its adaptability, it can be installed in even the most challenging of situations. Simply screw the threaded brass adapter that is linked to the air line into the fitting located at the top of the diffuser to complete the installation. By lowering the diffuser into the tank and even swinging it over into place if necessary, the spa-flex may help you save time and money. Curve the line up through the aperture and out the side, then up and into the bottom of the housing, where the other end is connected to the air pump (see illustration).
If you wish to expand the reach of the pump to a more remote place, this spa-flex may be bonded to 12 schedule 40 pvc pipe.
Installation and Maintenance Manual
Each SepAeratorTM kit includes a comprehensive Owners’ handbook that has all of the information needed to not only simply install the SepAeratorTM but also lots of information on how to use it properly after it has been installed. You will receive an abundance of information when you purchase a SepAeratorTM along with all of the technical help you may require to answer any and all of your questions both before and after installation by calling 1-877-925-5132 after you make your purchase. If you have any questions, please do not hesitate to contact us.
HOW IT WORKS
When a stool is flushed in the home, the wastewater drains into a drainpipe that transports it underground to a septic tank, where it is treated. Essentially, the objective of a septic tank is to provide an environment for anaerobic bacteria (bacteria that flourish without oxygen) to break down waste over time. Having an entrance baffle as well as an exit baffle is important to prevent waste from entering the tank and float right over its top before discharging to a secondary treatment system, which is what happens in most homes (drain field, sand filter, mound system, drip system, cesspool, dry well, etc.).
It is common for the septic tank discharge to include 70 to 80 percent raw sewage to be discharged to the drain field, where the raw sewage is treated by passing through a build-up of a material known as biomat.
What is Biomat?
In the secondary treatment system, a biomat is a layer of bacteria that develops in the soil throughout the treatment process. This biomat is extremely significant in the treatment of raw sewage that is often discharged from a septic tank or a cesspool. Septic tank output contains several minute waste particles and pathogens that must be processed before soil absorption can take place, and this is what this device is designed to do. A lack of this procedure allows improperly treated effluent to pollute groundwater, which can then end up in wells, streams, ponds, or even the surface of the earth itself.
Once the septic tank effluent is discharged to either a drain field or a seepage bed, the biomat that forms will efficiently reduce the waste particles and pathogens to an acceptable level before they can be transported further into the soils around the drainage field or seepage bed.
Septic tank effluent that has not been adequately treated should be regarded unsatisfactory and should be addressed promptly.
The Issues Caused By Biomat
During the course of time, the biomat grows in size, making it impossible for effluent discharged from the septic tank to pass through it, causing the effluent level inside the drain field trenches to rise, where it will be absorbed through the walls of the trenches as they develop. After a period of time, the sidewalls of these pits will begin to choke with accumulated debris. As soon as the bottom and sides of these trenches get blocked with biomat, the effluent will either begin to back up into the septic tank or surface in the yard above the drain field, depending on its location.
- If the effluent level in the septic tank rises by 4 inches as a result of the inability of the sewage to reach the absorption field, the effluent will begin to back up the entrance line.
- It is the intention of biomats to slow the flow of wastewater to the soils, giving the soils more time to filter out germs and viruses.
- It is therefore possible for the septic tank effluent to either back up into the residence or discharge to the ground surface, which will result in ponding of water.
- Septic systems that are failing due to biomat accumulation include, but are not limited to, water or sludge rising at the drain field, high water levels in the septic tank or distribution box, and sluggish running and gurgling drains and toilets, among other symptoms.
How The SepAerator® Can Save Your System
Biomat is comprised of anaerobic bacteria and the waste formed by these anaerobic bacteria as a result of their digestion of the 70 to 80 percent organic matter released from a septic tank, respectively. When you use the SepAerator® to convert your septic tank to the aerobic process, the septic tank transforms into a wastewater treatment plant that discharges around 95 percent pure, odorless water. It is only by eliminating this organic material waste from the effluent that you are able to completely eradicate the food supply that the biomat relies on to develop and live in the drain field.
- To learn more about the SepAerator®, click here.
- The SepAerator® will inject enormous volumes of oxygen into the septic tank, resulting in the fast proliferation of aerobic bacteria within the tank as a result of the introduction of oxygen.
- Septic tanks are designed to process waste rather than releasing it into a drain field, seepage bed, sand filter, mound system, cesspool, or any other form of secondary treatment system you may have.
- As soon as the waste is treated within the septic tank and clean water is sent to the secondary treatment system, the biomat will lose its food supply and will die within a short period of time.
- As a result of the clean effluent created by the SepAerator® being combined with high volumes of aerobic bacteria entering the secondary treatment system, the biomat will be destroyed, allowing the clean effluent to readily permeate back into the soils.
Because aerobic bacteria are extremely successful at decreasing disease-causing pathogens, the septic system has been completely rejuvenated and transformed.

Aeration pumps for septic tanks and aerobic treatment units. The size and design requirements for aerobic septic tanks, also known as ATUs, and aeration pumps are discussed in this article series. There is no charge. The four-chamber aerobic wastewater treatment unit seen at the top of this page was modified from a sewage system handbook published by the Taranaki Regional Council in the country of New Zealand.
For this topic, we also have anARTICLE INDEX available, or you may check the top or bottom of the page.
Aerobic Treatment Unit Aerator Pump Requirements
- In home aerobic septic systems, diaphragm type aerator pumps are likely the most extensively utilized form of aerator pump. Linear air pumps, which are used in aerobic septic systems, compress and pump air using a diaphragm or pistons. Brands such as HiBlow, Medo, and Thomas, as well as Cyclone, Secoh, and Alita air pumps, are examples. rotary-vane air conditioning Pumps for aerobic septic systems that employ spinning carbon steel vanes to compress the air are known as compressor air pumps. Durable, requires more power, and is noisier than linear air pumps. Regenerative Blowers for aerobic septic systems are utilized on Hoot septic systems, Fast septic systems, and Bio-Microbics systems, among other types of systems. These pumps are often controlled by a timer, which allows them to be turned on and off as needed. They do not run continually
- Instead, they run intermittently.
Typical Aerobic Septic Air Pump Capacity Ratings
The output of aerobic septic air pumps is measured in cubic feet per minute (CFM) or liters per minute (LPM) of air flow. A common septic aerator pump may provide 5 CFM (80 LPM) of air output, which is normal. The normal flow rate of septic air pumps for residential septic systems is around 2 to 8 cfm, or approximately 40 to 200 LPM of air flow rate. There is, in fact, something difficult to grasp about these evaluations. In fact, when the output is restricted, as in a septic tank, a septic air pump rated for 100 LPM air output at “open flow” (or un-restricted output) would actually give a lower flow rate than when the output is unrestricted.
Question: How do I size the correct aerator pump for my ATU?
11/5/2015 Josh asked:How can I determine the proper size of an aerator pump for my ATU? My system has a capacity of 600 gallons. We have 5 individuals living in our home, with visitors occasionally numbering as high as 10. Is it necessary to have two pumps, or may I operate them in parallel?
Reply: aerobic septic pump sizing table
Josh I’m sorry, but I don’t have an answer to your very fair question. All of these factors add up to “consult with your aerobic septic designer or aerobic pump sales or supplier contact” when determining the necessary aerator pump size or cubic feet per minute of air supply required:
- The intricacies of how your particular system was constructed, which vary depending on the company and model you have
- Average and maximum daily wastewater flow into the septic system
- The size of the septic tank
- The design of the actual aerator or bubbler
- The distance from the aerator pump tank
- The size or diameter of the piping
- The length and limits such as the number of elbows
- And other factors. because of the depth of the bubbler, which is a measure of how far the aerobic pump must drive air down and hence how much pressure the aerobic pump will meet
Intricacies of how your individual system was developed, which vary depending on the manufacturer and model; Water flow rates into the septic system, including average and maximum daily wastewater flows; the septic tank’s capacity; the actual aerator or bubbler’s design; the distance from the aerator pump tank; pipe sizes or diameters, length; and constraints, such as the number of elbows; because of the depth of the bubbler, which is a measure of how far the aerobic pump must drive air down and hence how much pressure the aerobic pump will meet.

Notes to the table above
Cfm is an abbreviation for cubic feet per minute. gpd is an abbreviation for gallons per day in the United States. lpd = litres per daylpm = liters per minute (or litres per minute in the United Kingdom) We recommend that you verify that the aerobic pump you choose has been authorized by the NSF (National Small Flows) for use with your system before purchasing it. You may get a more exact estimate of your daily wastewater consumption fromSEWAGE FLOWDESIGN FLOW ESTIMATESand then return to this page by using the “back” button on your browser.
It is recommended that you consult with the designer or manufacturer of your individual aerobic septic system since the manufacturer’s parameters may differ from those included in this general table.
Making this change alone, without making other critical design changes such as adding outlet filters or a settlement chamber, may agitate the sewage in the septic tank, causing solids to flow into the septic drainfield or absorption bed, resulting in the clogging of the drainfield or absorption bed and the rapid destruction of the system.
Aerobic Septic System Air Pump Specifications
2017/09/21 In response to Dexter’s question, “How do you check the air pressure on a pump to ensure that your diffuser is not clogged?” and “What should the air pressure measurement be?”
Reply: aerobic septic air pumps are rated as open flow in CFM or LPM but air pressure readings can be diagnostic
Thank you for your inquiry, Dexter. If you’re wondering what the optimal air output for an aerobic septic system air pump should be, there isn’t a single “correct answer” (also referred to as septic aerator pump or septic diffuser pump, or septic air pump or septic “compressor” pump). This is because, based on the size of the septic tank and the amount of waste produced on a daily basis, the pump model will be selected to meet a certain output rate. A septic air pump’s rating is often determined by water pressure rather than air pressure, because the pump’s output end is meant to be exposed to water and ultimately the atmosphere.
Another way to say it is that, although though the aerobic air pump has a pump operating air pressure capacity, the pump output is often given by the manufacturer as “open flow” capacity in cubic feet per minute (CFM) (or LPM).
That is why I stated that it is difficult to quantify.
What Air Pressure Could be Seen at a Septic Air Pump?
Using the Hiblow HP-80 aerobic septic air pump as an example, the manufacturer rates the pump’s maximum airflow at 4.2 cfm (119 LPM) when the pump is operating at 0 p.s.i., and the rated air flow will be LOWER – about 80 LPM (2.83 cfm) when the pump is operating at the rated pressure of 2.13 p.s.i. when the pump is operating under actual installed conditions. As a result of the fact that unique septic air pump specifications will change among manufacturers’ brands and models even before the pump is installed, you should make a note of the precise brand and model of the pump you are using.
- The pressure range will most likely be between 1.5 and 5 psi.
- To put it another way, if we went underwater (I don’t want to swim beneath sewage) and went down to 30 feet, we would be at one ATM of pressure, which is approximately 14.6 psi more pressure than being on the surface of the ocean at sea level.
- 1/6 of 14.6 psi is equal to 2.4 psi.
- If the pressures at our magic Tee, which we inserted in the air line, were lower than the manufacturer’s specifications, the pump (or the air line) is most likely malfunctioning (or there is an air leak).
If we notice pressures rising over what the manufacturer has specified, it is possible that the diffuser has become blocked. However, skipping the tee and the pressure gauge and simply looking for bubbles is more convenient.
Question: what are the aerobic septic pump tubing or piping distance limitations?
The following illustration depicts the drop in net air flow or CFM as a function of increasing pressure in the delivery system over zero limitations at the pump output for the Secoh EL-series aerobic pumps: CFM or LPM performance curves for the Secoh EL-series aerobic pumps. – derived from Secoh, which is discussed in further detail below. 2019/02/18 Bill Grambsch wrote: “I’d want to relocate my Aeration air pump 50 feet away from my septic tank,” he explained. I have 50 feet of 1/2-inch PVC tubing as well as the electricity to run the air pump.
Do you have any difficulties or concerns?
Is there any reason why I cannot add a 50-foot air hose to the system to eliminate the noise?
Reply: keep aerobic air pump tubing or pipes as short and straight as possible or risk inadequate aerobic treatment and system failure
Bill, Thank you for presenting such a thought-provoking question: What is the impact of distance on the performance of aerobic septic tank aerators? or What is the maximum length or distance of tubing that may be used with an aerobic septic aerator pump? The Secoh EL-80 septic pump is available in a variety of versions with air supply rates ranging from 2.83 CFM to 4.23 CFM. The pump is rated as Air Flow: 80LPM or 2.83 CFM to 4.23 CFM Open Flow. The performance curves for Secoh aerator pumps given below (which were taken from the company’s sales brochure) clearly demonstrate that as the pump’s “PSI” increases, the flow rate declines.
It is vital to comprehend the concept of “open flow.” It is possible to measure open flow at the pump’s exit since there is no resistance on the pump’s side.
The following is how septicsolutions, a vendor of septic aerators, puts up the problem: It is customary for the size of the air pump to be dictated by the volume of the tank, the kind of air diffusers installed in the tank, and the number of GPD (Gallons Per Day) that the system is meant to treat.
Keep an eye out for: In practice, this implies that, assuming that your septic aerator pump was correctly sized and installed in the first place, you should not relocate it more than 50 feet away without first contacting with Secoh or the firm who built and installed your aerobic septic system.
- Keep in mind that if the air flow rate, volume, duration, or CFM / LPM in an aerobic septic tank is insufficient, the expense might be crippling.
- I’m sorry for not being able to provide a more precise response, such as – yes, if you use 3/4″ tubing – but, like Secoh, from my vantage point in central Mexico, I cannot see your aerobic septic installation and so have no more information about it to share with you.
- Septic Solutions is located at 314 Center St.
- According to Secoh, the following pipe requirements are necessary for their air pumps: PIPING: Choose tube sizes, lengths, and attachments carefully to ensure that pressure loss is kept to a minimum.
- Using tubing with a diameter that is greater than the port on the device (inside diameter min.
- There are no elbows and the bends are of great radius.

Other aerobic septic system aerator-air pump checks you can make
Make sure of it.
- The fact that the aerobic aerator pump is operational
- Aerator pump is providing air to the septic tank as shown by the appearance of air bubbles at the tank top inspection port
- This includes making sure that the aerator pump tubing or pipe is not restricted, bent, kinked, or clogged with debris. That you are completing the periodic maintenance on your aerator pump in accordance with the manufacturer’s recommendations – samples of aerobic pump maintenance and installation manuals are provided below
- When the pump stops operating or is turned off, certain septic air pump types incorporate an alert feature to notify you of the situation. The fact that you may leave your aerobic system without its aerator means that the system is not operating well, it is not treating sewage effectively, and the system might fail in a matter of days
- This is a convenient feature.

Top Quality Septic Air Diffusers – Wholesale Septic Supply
Septic systems aerate wastewater by pumping air through it as it passes through the system. When using an aerobic septic system, this step is crucial because the bacteria that devour waste in the water require oxygen to exist. Aeration is necessary to prevent the demise of aerobic microorganisms, which results in the system’s inability to efficiently treat wastewater. However, there is a limit to how much air may escape from huge bubbles and enter the wastewater system. Diffusers are used to break up the air entering from an air compressor into a large number of little bubbles, which are then released into the atmosphere.
Bacteria then take advantage of the oxygen and begin to treat the effluent.
Diffusers
These are tubes or plates that are often designed with tiny mesh to allow for the passage of water and oxygen through them. The pores are small to guarantee that the bacteria may take advantage of and survive on the tiny bubbles that are there.
After a period of time, the mesh will darken and become blocked with microscopic particles. You should consider changing your diffuser about every three years in order to avoid a buildup of sediment and harm to your septic tank.
Types Of Diffusers
Diffusers come in a variety of shapes and sizes, just as there are several uses for aerator pumps to suit diverse needs. Larger bubbles are produced by coarse diffusers, which aid in the circulation of wastewater. Fine diffusers generate tiny bubbles that aid in the dissolution of oxygen into wastewater. Fine diffusers, on the other hand, make it more difficult for the aerator to transfer air into the septic tank.

Aerobic septic tank effluent odor

| Aerobic septic tank effluent odor
Our 12 year-old system has 2 750 gallon tanks with air pump that runs 27/7. The effluent smells like sewer water when the pump/sprinkler comes on. The system was pumped out about 6 months ago.That helped for a while, but the odor returned in about 2 months. How can I determine if the air pump is producing enough air volume and if the air is being pumped into the tank? Would an additional aerator help?Thanks |

| Hi and welcome.Can you hear the bubbling in the tank? Sometimes the aerators that are outside the tank, can be running but no air is being put in the tank.If you have the one that sits out side the tank, the small diffusers in the tank may be stopped up, air line may be cracked, or the rubber diaphragms are busted.It just depends on the type of aerator you have.If you are smelling sewer the air is not getting to the water. |

| Unplug the air hose from the air pump and feel the outlet. Is there air blowing out?Those pumps need to be rebuilt ever once in a while.Under the airpump lid there is a aircleaner. It may be plugged. You need to clean it and inspect the pump.If there is air then possibly the line has a split. You will need to pull up the air diffuser and make sure all in intact. |

| How to find and clean the diffuser
So far, so good.I pulled the air pump hose and it is pumping a good volume of air. So the next thing is to check for a clogged diffuser.Being an amateur DIY’er, I have no idea where to find and check the diffuser. I assume it is in the first tank. Should I be able to find it by removing the clean-out cap on the first tank?Thanks for your patience and help. |

| More details
I pulled the cap from the 1st tank clean-out.Could not see anything but a pipe with about a 6″ elbow sticking up above the water line in the tank. Could hear water flowing at a pretty good rate but could not hear air bubbling over the sound of the water flow. Pulled the second cap and it appears that the flowing water might be water draining from the first tank into the second.Turned off the air pump and didn’t hear any difference in water flow. (Did not expect to hear any difference.)Not sure where to go from here. Do I need a pro at this point? |

| Follow the air hose. It cant be too deep. You should have access to the diffuser.Your best bet is to spend the small fee and have the tank emptied. $180 per 1k gallons here on the east. Then you should see all.Your sure thats a chlorine injector right? Any mane on the system any where? Jet air.etc. |
Fact Sheet: Home Aeration Units – Cavitette
The location where you now reside in Hamilton County is not serviced by sewers. A home aeration device is used to handle the trash generated by your household. These units are available in a variety of forms and sizes. They are also referred to as “cavitettes” in some circles. Cavitette is the brand name of one of the aeration units that is now in use in our county. Coate Aer, Jet, Multi-Flo, Norweco, and Oldham are some of the other brands that have been utilized.
Despite the fact that aeration units come in a variety of shapes and sizes, the essential concept of operation is the same: air pumped into sewage creates agitation and oxygen, which in turn helps bacteria to break down organic waste into carbon dioxide and water.
Treatment Process
Cavitette units are designed to create effluent that does not meet contemporary water quality requirements, hence they are not permitted to be used. A properly running unit, on the other hand, will discharge a clean effluent. The procedure that is followed is as follows.
- In the treatment procedure, cavitette units do not provide for settling during the primary phase (pre-treatment/settlement). This chamber receives raw sewage from your residence first, before proceeding to the next chamber. (See1) Aerobic microorganisms that degrade organic materials in wastewater benefit from the agitation and oxygen provided by the injected air. Clarification — Because there is no agitation in the second chamber (2), suspended particles that have remained in the aerated sewage can settle. It is designed in such a way that sediments flow back into the aeration chamber for further treatment.
In the treatment procedure, cavitette units do not perform filtration or disinfection. Tertiary (Filtration/Disinfection): Some units may be equipped with a separate chlorinator for disinfection purposes.
Care of your Unit
Your Cavitette treatment plant may have a capacity of 750 or 1500 gallons per day. Please keep in mind that certain aeration devices are positioned extremely deeply below the surface of the soil. Maintenance on the units presents unique safety concerns and should be carried out by a qualified professional with extensive expertise. You should call a maintenance firm that is registered and bonded with the Health District if you fulfill the previous conditions or if you are uncomfortable with the following processes.
Cracks in the lid that allow surface water to enter the system or that hinder Health District employees from inspecting the system should be looked for.
Aeration Tank– Remove the cover from the aeration riser and look for the following issues:
- If the electrical service wire is frayed or if there is a black residue on the wire, it should be replaced. A secure connection between the motor/blower and the diffuser bar should be made using the air supply line. No cracks or breaks should be present in the belt/coupler-belt. Motor/Blower-Whether the motor/blower is not functioning, gently touch it to see if it is warm to the touch. If the motor is chilly, it should be replaced or repaired. Remove the porthole cover from within the aeration riser so that you can see the aeration process in action
- The presence of turbulence and air bubbles in wastewater indicates that aeration is taking place. Replace all of the lids.
Removing the cover from the clarifier’s riser is the first step. It is necessary to install a riser if one does not already exist. The liquid under the surface should be clear, not hazy or grey. The buildup of floating particles should be skimmed off and disposed if there is an accumulation. It is recommended that a compartment be pumped if the scum layer is greater than 6 inches thick. Check to see that the baffle is still in place and has not degraded. Discharge Point– Make that the discharge point is working properly.
Even when the systems are running effectively, the discharge locations of aeration units are not suitable play areas for children to play.
Managing your Unit
Wastewater treatment plant pumpers are required to be registered with the Health District. The primary goal of tank pumping is to remove sludge from the tank. It is possible that you may need to be there during the pumping process to ensure that all sludge and wastewater is removed. Contract repairs must be carried out by licensed and certified specialists. Call the Health District at (513) 946-7966 if you would like to be included on a list of certified pumpers and contractors.
