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 the cost of installing a Cesspit?

What is the cost of installing a Cesspit (Cesspool)?

Unlike a septic tank, a cesspit is a simple unit.

In short, a cesspit is a wastewater system which holds the waste until it is full and needs to be emptied.

A septic tank is a wastewater system which not only holds the wastewater but also treats and discharges some of its contents into the environment around it (through a soakaway). This is similar to a Sewage Treatment Plant system.

If you are currently researching ” What is the cost of installing a Cesspit (Cesspool)?”, then there are a few things to consider.

The size of the tank.

The size of your cesspit (cesspool) will inevitably affect the cost.

The larger number of people living within the property, the larger the tank will need to be. It is common to think that a larger property will require a larger tank, but if it can only hold a small number of individuals, then the waste is likely to be minimal.

A small-sized cesspool can cost upwards of £1000, whereas a larger system can cost £1500+

Labour and materials.

Like most things, the materials your system is made from will unsurprisingly affect the cost of the unit. You would potentially assume that all tanks are one and the same, but this is a misconception. Our advice would be not to cut corners and invest in a unit that will give you longevity. The Septic Tank will give you a return on investment over time so make a wise choice.

There are various different companies which offer an installation service, but it is recommended that you discuss an installation with your local waste management company. They will have the best knowledge on what to avoid and the best course of action.


Overall, the simple answer to your question “What is the cost of installing a Cesspit (Cesspool)?” is: Your investment levels will vary depending on the choices made, but on average, the whole project should cost between £3000 – £6000.

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.

Top Tips for Septic Tank Maintenance

Top Tips for Septic Tank Maintenance

Your septic tank will efficiently manage your waste water, however, like all things it requires a bit of maintenance to ensure it continues to do so. A lack of maintenance will increase the likelihood of damage to the tank and surrounding environment and it could potentially shorten the tanks lifespan, all of which can be expensive issues to fix. So here are our Top Tips for Septic Tank Maintenance:

Keep an eye on your septic tank and have it regularly pumped to keep it working optimally.

-Carry out regular inspections and keep records to spot faults early. If you are in doubt about whether septic tank is working properly, West Wales Waste will be happy to advise.

-Have the tank de-sludged regularly. The more waste your tank holds, the less efficiently it will run. This should be done ideally every six months but there are factors to consider which will influence this. Check out our guide ‘How to know when your septic tank needs emptying‘, how much it will cost to empty your septic tank will vary too.

Properly dispose of waste and use biologically friendly cleaning products.

-Don’t allow commercial chemicals, medicines or hygiene products to enter the system

-Don’t use large quantities of biological cleaning products or bleach

-Bacteria in the tank is vital to the biological process and can be harmed if you dispose of anything other than human waste, toilet paper and a small amount of biologically friendly cleaning products.

Think about how much water you are using.

-Overloading your septic tank system with too much water can the septic tank to become weakened, damaged or blocked.

-Fix leaky taps or toilets, install energy efficient toilets and shower heads, and only put that washing machine or dishwasher on when they’re full. Try and space your use of the washing machine and dishwasher use out over a few days or use a small load settings for small loads.

-You could also try and spend less time in the shower, think before you flush and use toilet tissue which breaks down easily when wet too!

Protect Your Drain Field.

-The drain field of a septic tank is as important as the tank itself because the tank works as a system rather than a storage facility for your waste water.

-Prevent backlogs and overflows by not parking on your drain field and avoiding planting trees to ensure roots don’t interrupt the flow of the waste water.  Talk to a septic tank professional if you are unsure as to how far away would be an appropriate distance.

-Try to keep other drainage systems away from your drain field. The location of roof and rainwater drains and sump pumps should be thought about to prevent it slowing or stopping the wastewater treatment process.

How do you know when your septic tank needs emptying

How to know when your septic tank needs emptying

Septic tanks are an effective way to store liquid waste, but when they fill up, they have to be maintained and emptied to prevent any damage to the environment around them.

Understanding the signs your tank is full is extremely important in order to prevent costly issues.

The answer to ‘how to know when your septic tank needs emptying’ will be indicated by the following signs, and should be acted on as soon as possible:

Seeing puddles around your tank:

This is a good indication that the solids within your tank have blocked up the system and is forcing the liquid waste to the surface. The problem needs to be investigated as soon as possible and emptied swiftly if need be.

Unpleasant smells:

One of the clearest signs is an increase in the amount your tank will smell. You can envision the kinds of scents to expect and they will become worse/more noticeable when the cesspit needs to be emptied.

This will usually indicate that your system is due an empty.

Slow working drainage:

It’s not uncommon for us to be called out to a blocked drain to discover a full septic tank is the cause. The best way to know if you have either a septic tank issue or a blocked drain is to identify the number of drains affected by slow draining fluids. If only one drain is affected, then this is an indication that you have a small blockage. But, if all of your drains seem to have the issue, then most likely you have a full septic tank.

Greener grass:

As much as it’s great to see a nice lawn, lush green grass around your septic tank could spell trouble. You will most likely see the grass greener in patches rather as the septic tank will leak in various directions.

Drains backing up:

The biggest headache of them all is when your drainage backs up. This will leave you with a very unpleasant clean up and a costly bill on disinfectant and cleaning materials. The tank will usually affect the drains at the lowest parts of the property first, but it is obviously good to identify the issues before it gets this way.

Keeping tabs on your septic tank is important as overflows will become a regular issue if the problems aren’t addressed. It is also important to maintain contact with your local waste management company in order to keep a record of how often they have emptied your tank.
