Klargester Sewage Treatment Plants FAQs

How often should I empty my Klargester tank?

Sludge builds up in septic tanks and it must be regularly removed to keep your Klargester tank working for as long possible. Tanks that are poorly maintained will need repairing or replacing sooner and could experience issues like bad smells, blocked pipes, cracked and blocked pipes, and failed motors and pumps. You may also notice soggy ground and pools of water forming around the drainage point, a sign that the effluent is not draining from the house quickly enough, are all indications that your Klargester septic tank is not coping.

You should get the sludge that builds up in your septic tank removed, a process called 'desludging' before it exceeds the maximum capacity. We recommend your Klargester tank should be desludged a minimum once a year and always ensure that the company you use to remove the sludge is a registered waste carrier. 

How does a BioDisc work?

The BioDisc uses a Rotating Biological Contractor (RBC) system which includes three stages to treat waste water. After the water has passed through a primary settlement tank, where heavy solids settle to form a sludge in the bottom of the tank, it moves into the Biozone for breaking down by microorganisms on the RBC. Suspended solids return to the primary settlement zone, and the liquor is transferred to the second stage Biozone for further treatment. Any remaining solids are settled out in the final settlement tank, leaving the remaining effluent clean enough to be discharged into a watercourse.

Do I need planning permission for a Klargester septic tank?

If you are planning to install a new septic tank, you will need planning permission from the local authority. This applies to residential sites, as well as commercial. If you already have an existing septic tank installed, either at home or as part of your business premises, you won't need planning permission if you are simply intending to replace it. It doesn't matter how old your existing septic tank system is €” you can have it upgraded or replaced entirely, and you won't require planning permission from your local authority.

How close can a septic tank be to a dwelling?

Septic tanks sit underground and release wastewater slowly into the surrounding environment. For this reason, they must be installed at least seven metres away from a house or 'habitable property' and at least 50 metres away from any water sources. It is very important that you comply with all regulations for both health and safety and environmental reasons. You will also need to check if you need a permit, which usually depends on where you intend to release your wastewater.

How much does it typically cost to install a septic tank in the UK?

There are lots of factors that might affect the cost of replacing or installing a new septic tank. Costs can be high depending on where you live, the type of ground you're installing the septic tank into, and many other factors. After you have selected and paid for your chosen septic tank, the installation cost could be anywhere from £2,000 to £4,000.

With replacement septic tanks, a lot of the infrastructure like pipework, plumbing and foundations will already be there €“ helping to keep costs down. Remember, though, that you'll need to empty out all the sludge that's built up over time from the old tank and rinse it until it's safe enough to remove to the waste disposal site. New septic tank installations will require new plumbing, pipework, and foundations, as well as somewhere to dispose of the soil or ground dug up. Installing your septic tank could take anywhere from three to seven days, all which will be factored into the price.

How does a Klargester Septic tank work?

A Klargester septic tank disposes of the sewage and wastewater from your property. It collects the wastewater from your property and separates the solids from the liquids, and then any leftover effluent is discharged into a drainage field or soakaway.

There are three different types of septic tanks, each with their own benefits and suitability to different properties and individual requirements.

 

The Alpha Klargester septic tank

One of the most popular Klargester septic tanks, the Alpha tank is light, watertight, and particularly strong. Thanks to its shape the tank is easy to handle and install and has a subtle visual impact that many people find desirable.

 

The Sigma Klargester septic tank

Light, robust, and chemically resistant, the Sigma Klargester septic tank is one of Klargester's easiest tanks to install. The reduced excavation costs make the Sigma Klargester a popular choice.

 

Gamma Klargester septic tanks

If you're looking for a more environmentally friendly choice, look no further than the Gamma Klargester septic tank. It is easy to install, durable, strong and lightweight.
