What size is my Sewage Treatment Plant?

What size is my Sewage Treatment Plant?

One of the first questions we tend to ask when we receive an enquiry for a Sewage Treatment Plant empty is “What size is your Sewage Treatment Plant?”.

Although you may assume you should know, we completely understand that it is not the most basic question to answer. You may have recently purchased or rented the property and there may be little knowledge on the waste system.

We normally ask the question though in order to assess the amount of waste we need to collect. This helps us organise the correct equipment and vehicle for the job in hand.

As this information is quite difficult to know off-hand, we have put this blog together to help you find out the size of your Sewage Treatment Plant.

Tip 1 – Documents.

In some circumstances, the property owner will have documentation of the Sewage Treatment Plant installation. This documentation will normally hold the information we need to identify the exact size of the tank itself, or at the least give us a good indication.

Tip 2 – Inspection.

We will normally recommend an inspection of the tank on arrival for the empty. If no information can be found then an inspection is the best way for us to gather the information we need.

In this scenario, we will normally bring what we assume to be correct equipment on the day of inspection so we can get right to work if we feel we are fully prepared to empty the tank there and then. This is the case a good majority of the time.

Top Tips for sewage treatment plant maintenance

Top Tips for Sewage Treatment Plant Maintenance

There are a few key ways in which you can help keep your sewage treatment plant in good working order. Our top tips for sewage treatment plant maintenance are as follows:

Use biologically friendly household cleaning products. The sewage treatment plant process is known to be the most environmentally friendly because it basically encourages the growth of bacteria to break down sewage by circulating air through the system to produce a much cleaner effluent. If commercial chemicals, medicines or hygiene products enter the system they will kill the bacteria and prevent the breakdown process from working properly.

Similarly using large quantities of biological cleaning products or bleach will also disrupt the equilibrium of the bacteria in the tank. In addition, anything you put down sinks and storm drains can end up in local watercourses or the sea so it is worth thinking about this alongside the fact it will potentially prevent your sewage treatment plant from working properly. Fats, oils & grease cause additional problems as they can block drains and cause backups, as do disposable items such as wet wipes and nappies.

Have the sewage treatment tanks de-sludged regularly, ideally every twelve months. However, some of the lower budget treatment plants will require emptying more frequently. This should be carried out by a licensed waste carrier.

De-sludging your sewage treatment plant will help to maximise the working life of the components and will prevent the effluent quality from deteriorating. You will notice if it has if the final effluent this is cloudy or contains many suspended particles, then the final settlement tank. If this is the case you will need to have your tank checked over but ideally you will prevent this from happening if you carry out our top tips for sewage treatment plant maintenance.

You could also consider carrying out a full service of your sewage treatment plant around every 24 months. However, it would be worth checking over the components of the sewage treatment plant more regularly so you can spot problems early.

What is a sewage treatment plant?

What is the cost of installing a sewer treatment plant?

What is the cost of installing a Sewer Treatment Plant?

When looking at installing any wastewater system, there can be many different cost involved. So the answer to “What is the cost of installing a Sewer Treatment Plant?” is not necessarily a straight forward one. From the system itself to the labour of the project – all of these have varied cost implementations.

It’s important to remember that the overall cost of this system may seem high at first, but it is essential to remember the savings you will make in the long term.

By installing a sewer treatment system, you will help protect the environment. The sewage you will be discharging will be treated within the system before it is introduced into the surrounding area. This also helps breakdown and dispose of viruses and diseases which spread from the surface water.

If your sewage treatment plant is an upgrade from a previous system, then you are most likely going to avoid any fines from the Environmental Agency. If you are not up to date already, please read our article on the new 2020 septic tank regulations.

What is the price of a Sewage Treatment Plant?

For obvious reasons, the prices are widely varied. It will all come down to the size of the tank and the number of people who will be using it.

To calculate this, most people will either follow the rules outlined in British Water Flows & Loads or alternatively, you can take the advice of the company selling you the tank itself.

Tanks can cost anywhere from £1000 to £15,000 depending on size.

What is the cost of the install?

When we quote the installation of a sewage treatment plant, we assess the tank that is will be installed and the time it will take to complete the installation.

No concrete backfill is needed for the project which will only add to the savings you can make. However, you will still need to excavate where the tank will be installed. Some customers may require a discharge permit if they don’t conform with the general binding rule by National Resources Wales. This will require an application fee. On top of this, you will require planning permission and building regulation approval. But once all these have been completed, the process should go smoothly.

How much does a Sewage Treatment Plant cost to run?

Not many people are aware, but most sewage treatment plants have to have a power supply. This powers the electric air blower housed within the system. This air blower supplies fresh air which helps feed the bacteria within the tank. This will only cost roughly the same as a single lightbulb.

On top of this, you will regularly need to desludge/empty your tank when it is required.

With all this in mind, the cost of running the system will still be extremely cost-effective in the long run.

It is advised that you have you check your treatment plant regularly.

These checks should include:

· All vents should be checked to make sure they are not blocked or obscured.

· Ensure the air blower is working by listening for a gentle hum when standing beside the plant.

· Inspect pipework for blockages if necessary

· Sludge return

· Functionality of blower and/or pump

· Pump pressures

· Pump filters are replaced

· Pump Diaphragm

· Alarm

· Ventilation function tested

· Diffuser monitored to check for dispersion of air

· Tricel covers and locks

· Manifold adjusted

what is a soakaway?

What is a Soakaway?

Soakaways are installed to manage any surface water from either a rainwater or sewer system.

It can be a highly effective way to deal with any surface water which collects in the surrounding ground/earth.

Soakaways are important to control the levels of surface water, avoiding flooding from excess rainfall as well as other things.

Domestic Soakaways are most commonly found in the rear garden adjacent to a wastewater system, such as a Septic tank or a Sewage Treatment Plant. You will know if you have a Soakaway if you follow draining rainwater to the bottom of a garden, you will most likely come across a dip in the earth. This is a very good sign your property has a Soakaway.

Maintaining a Soakaway is important to the environment which surrounds it. When you have issues with your Soakaway it can be quite easy to notice. When inspecting your Soakaway, be on the lookout for waterlogging. This is the best indication that your soakaway is not dispersing the water effectively enough.

It’s advised that you regularly check for issues.

It is extremely important to know where a soakaway cannot be used before looking to install one.

The Environmental Agency has specific general building rules when it comes down to installing a Soakaway. Their regulations have changed recently for Septic Tanks, so if you already own a septic tank, click here to view the updated regulations.

Soakaways are not well known for handling wastewater drainage. This being said, your Septic Tank or Sewage Treatment Plant will have its own process to break down the effluent so that the Soakaway isn’t affected. Bacteria in the systems take care of the majority of the work when breaking down your waste, but having a good clean airflow into the tank will help feed the bacteria in order to carry out their job efficiently.

Once this process is complete, the waste that is discharged is environmentally friendly and should cause no harm to the environment that surrounds it.

The new septic tank regulations 2020

The new septic tank regulations 2020 – explained

The new septic tank regulations 2020 – explained

Regulations around discharging into surface water or watercourse(s) from a septic tank and similar wastewater systems have changed in England & Wales as of January 1 2020.

These regulations mean septic tank owners have been asked to upgrade their drainage if they have a particular type discharge process. However, the new regulations do not affect everyone.

If the owner has a septic tank which discharges indirectly away from a watercourse then the tank is still seen as lawful. More explanation is given below.

All sewage treatment plants which have full certification are and will be exempt from these regulations and will be operating within the law.

How will I know if I’m within regulations?

Your drainage from your septic tank will happen one of two ways. The best way to know if your system is within these regulations is to know the difference between the two.


A waterway allows the effluent discharge through a pipe and directly into a stream, lake or river. This is commonly known as ‘Direct Discharge’.

This method is affected by the 2020 septic tank regulations.

The law now states that direct discharge will no longer be permitted, and the owner will be advised to upgrade their system.

Drainage field:

A drainage field releases wastewater through a series of pipes into surrounding subsoils. This provides an additional form of treatment to the effluent from the septic tank. This helps the whole process become more environmentally friendly as it does not cause pollution.

This method is not affected by the new septic tank regulations.

Are any other wastewater systems affected?

As it stands, Cesspits are not affected by this particular regulation.

How to know when your septic tank needs emptying

What is a Sewage Treatment Plant?

The Sewage Treatment Plant

The sewage treatment plant process is known to be the most environmentally friendly because it basically encourages the growth of bacteria to break down sewage by circulating air through the system to produce a much cleaner effluent.

This process isn’t seen as too dissimilar to the septic tank, but there are some key differences to both systems which set them apart from their predecessor, the Cesspit.

Depending on the size of the treatment plant, they can commonly treat large commercial properties or a number of domestic dwellings.

Not too dissimilar to the septic tank, a sewage treatment plant collects sewage from a property into its first of three chambers. It stays here until the solids have settled to the bottom and grease, oil and scum have floated to the top.

Once this separation process has taken place the liquids (or liquor) travel into the second chamber where the air pump is activated and the bacteria is encouraged to breakdown the contaminants in the water.

Finally, the third tank allows the remaining solids to sink to the bottom while the effluent is discharged into the soakaway. It is important that the process is complete before it is discharged into the environment.

The core benefit of a sewage treatment plant is that the system only needs to be emptied around once a year. This being said, there is an added financial cost for the air pump and the electricity it uses to complete the process. This is estimated to cost anywhere from £150 – £250 a year.

A sewage treatment plants tank range in size, see below:

  • 1000 Gallons / 4500 Litres
  • 2000 Gallons / 9000 Litres
  • 3000 Gallons / 13500 Litres
  • 4000 Gallons / 18000 Litres
