Difference Between A Septic Tank & Cesspool

At Septic Tank Supplies we get asked daily what the difference is between a septic tank and a cesspool.

The simple answer is that a cesspool has no outlet and all the waste water is stored inside the system and needs to be emptied by a tanker, usually once a month depending on size and usage.

With a septic tank they have an outlet pipe and therefore only store the sludge and all the waste water passes on through the system and out into a soakaway. With a septic tank they are designed to be emptied annually depending on the size and usage this can be longer.

There are two types of cesspools supplied in the United Kingdom, there is domestic sized cesspool and commercial sized cesspool;

·         Domestic cesspools start at 18,000 litres and would cater for two people or a one bed room property and for every extra person another 6,800 litres needs to be added to size. Domestic cesspools are required to hold 45 days storage before requiring emptying.

·         Commercial cesspools are a little bit more tricky to size as you need to work out the flow that will be running into them. Commercial cesspools start at 2,800 litres and go right up to 79,000 litres. For help sizing a commercial cesspool please give us a call on 01923 261660.

             Commercial cesspools are ideal for camp sites, caravan parks and fishing lakes.

Cesspools are usually a last resort due to the size required and the constant need for emptying, but where a site has very little area for a soakaway or a high water table there may be no other solution.

Low Profile Septic Tanks

Low profile septic tanks (also known as cylindrical septic tank) have been available on the market now for just over a year and are becoming more and more popular.

The main reason more people are buying the low profile septic tank over the original onion shape septic tank is because, they are half the depth and allow smaller machinery to be able install the low profile septic tank.

Another key factor in the popularity of the low profile septic tank is, because of the shallow depth this allows for a shallower soakaway which in turn is great for areas with high water tables.

                                                                                             

At Septic Tank Supplies we are able to offer the Clearwater shallow septic tank which is the cheapest priced shallow septic tank on the market to date. We are also able to offer the Tricel shallow septic tank, which with the right ground conditions only requires a granular backfill saving £££ on the installation.

The low profiles septic tanks have two chambers, the first chamber is there to retain the vast majority of the solid build up (sludge). The second chamber is where the water builds up and leaves the low profile septic tank and goes off to the soakaway.

At Septic Tank Supplies we are able to offer both low profile septic tanks and also low profile sewage treatment plants.

SUDS Explained

The Environment Regulators, Environment Agency, England and Wales, SEPA, Scottish Environmental Protection Agency in Scotland and Department of Environment & Heritage in Northern Ireland, have published guidance on surface water disposal, which offers a range of means of dealing with pollution both at source and at the point of discharge from site (so called ‘end of pipe’ treatment). These techniques are known as ‘Sustainable Drainage Systems’ (suds).

Soakaway's



A vital part of any septic tank is its soakaway or drainage field, without this a septic tank may not be the correct option. (Sewage treatment plant or a cesspool)
Building Regulation state, soakaways should be sited so as not to have an adverse effect on the sub structure of any buildings

Apart from the Building Regulations there are various good practices regarding the positioning of a soakaway;

•    Avoid sitting within 5 metres of a road or highway.
•    Avoid sitting within 2.5 metres of a boundary.
•    Note that areas with a high water table are likely to be unsuitable.
•    Any new soakaway should not compromise existing systems.

Permeable sub-soils such as sand, along with permeable bedrock types, such as limestone, sandstone or chalk, are usually good areas to have a soakaways.
Whereas hard, igneous rocks, such as granites and basalts, and heavy soils such as clay may mean a soakaway is not going to be feasible.
There are many different type of soakaways available for septic tanks, the most common being a herringbone system.
Septic Tank Supplies are able to supply both 110mm sewage pipe and 110mm perforated pipe used in the installation of soakaways.

Design and Construction of your Soakaway
Soakaways should be always constructed with perforated pipe, and laid in trenches with the same gradient not steeper than 1:200
Pipes should be laid on a 300mm layer of shingle or medium of up to 50mm.
The trenches must be filled 50mm above perforated pipe and covered with a membrane and then filled in with soil.
The trenches for a soakaway should be between 300mm and 900mm wide with a distance of 2m between trenches.
It is recommended that an inspection chamber should be installed between the septic tank and the soakaway. (this is to make sure no solids are coming out through the outlet pipe into your soakaway)

Other Factors
Drainage fields are not to be constructed under driveways, parking areas, buildings, neartrees, dwellings, boundaries, watercourses & boreholes.

EN-12566-3 2005 Explained

EN12566-3 2005 is the new customary certificate for sewage treatment plants that are sold within Europe. The construction of products Regulations from 1991 now state that any sewage treatment plant that are sold within the EU must have the subsequent specifications -

1)  Should be a hundred per cent watertight

2)  The sewage treatment plant has to be structurally sound 

3)  Must have the correct capacity to hold waste water for an enough time before needing to be emptied. This allows a maximum period of time for the sewage to be treated, for this reason the discharge will be cleaner and therefore more environment friendly.

All of these necessities are complying with the British Environment Agency commandments, which is not optional. All manufacturers and suppliers in the United Kingdom need to be able to prove that the sewage treatment plant that they sell are compliable with the regulation set out by the British Environmental Agency. If a sewage treatment plant has not been tested to EN12566-3 2005 you should stay well clear as the Environmental Agency will not allow this system to be installed and if found out would be well in their right to issue a very large fine.

The British Standard Institute  said that they only want sewage treatment plants with a EN12566-3 2005 Certificate on the United Kingdom market.  The Environment Agency have also said that only sewage treatment plants that have the EN 12566-3 2005 Certificate are allowed to obtain the Environment Agency Exemption Certificate which you have to apply for.

Because these restrictions apply to all of Europe you will be unable to import an inferior sewage treatment plant from mainland Europe. 

Although the EN 12566-3 has very high guidelines and tests, it requires only a percentage reduction of the sewage effluent and therefore it does not guarantee that the final effluent will please the Environment Agency consent standards that must be satisfied, because of this at Septic Tank Supplies we are happy to offer a wide range of sewage treatment plants all certificated to EN 12566-3 2005.

Sewage Explained

Sewage, also known as waste-water,  is water based waste that normally needs to be removed from an area.  It commonly contains physical, chemical or biological waste.  There are different types of sewage, ranging from commercial, agricultural, sanitary and surface water -waste.  Sewage is often discharged from a property through a underground drainage network.  It is then needed to be carried off to be treated before being released back into the environment. There are many different ways to treat sewage, and many countries vary their approach.

In most countries there is a national sewage system, however not all properties are connected, depending on their location.  If this is the case then you will have to install and maintain either a septic tank, sewage treatment plant or a cesspool.  Cesspools are only used as a last resort if a soak away cannot be installed.  A soak is where the treated sewage water is discharged over a large sewage area.  It consists of a network of perforated  drain pipes usually in a herringbone system, that lets the water drain naturally over a period of time back into the ground.   Most people currently prefer the sewage treatment plants, as it is better for the environment and has the option of being discharged into a watercourse with consent.

There are so many reasons we need to make sure that all forms of sewage are collected in a safe manner and then dealt with, making sure that all toxic substances are removed before the treated material is then reused. At Septic Tank Supplies we make sure all the sewage tanks we sell have been tested to the latest certification to be used in the United Kingdom.
