Another job that we have done recently was for a customer which required a Vortex Installation.

To the right you can see an image which represents the starting point of our Installation process.

As you can see the ground here was quite soft and quite easy to dig into.

This was probably the easier of the three installations that we have blogged about.

What we achieved.

As you can see on the right we have two pictures which show the completed installations. As you can see the ground has recovered most of the grass that it had lost during the time we had performed work on the ground.

Falcon Installation.

Falcon Installation is something we have great expertise in at Keens Drainage Services.

Falcon Installation

One job that we recently took on involved the installation of a Falcon.

The picture on the right shows the job halfway through completion and.

We find that although Biorock, Vortex and Falcon are different manufacturers the installation procedure is all very similar.





Falcon Installation


As with the Biorock Installation we did encounter some problems digging through the ground to make enough space for the product to go in.

As you can see on the picture to the right we did encounter some problems with the terrain with regards to the density of it.




Falcon Installation

End Result.

Even though we did encounter terrain difficulties we did manage to successfully install the Falcon.

Biorock Installation.

Biorock Installation

At Keens Drainage Services we specialise in the installation of Biorock septic tanks.

We recently installed a Biorock septic tank and this post is to help give customers some idea of what it takes to install a septic tank.

To the right you can see an image of the Biorock Septic Tank during its installation.

The main issue with installing any septic tank is that sometimes it requires a lot of planning permission to be allowed to even carry out the installation.



Biorock Installation

The end result.

As you can see in the second image this is what you can expect to see once the septic tank has been installed.

With this particular job in hand we did have some difficulties digging up the ground due to the surface we were working with. We are finding that sometimes to even think about working on a piece of land we have to hire a meteorologist to survey it to make sure it is something we can install a septic tank into.

In our experience of many years of clearing blocked drain lines in the Dorset, Hampshire and Wiltshire areas tells us that the average persons general conception of drains is ‘Out of sight out of mind’. We never give much consideration to the items that we flush away until we have our drain blocked and bubbling up through the manhole.

Blocked drain Line

Most blockages are caused by sanitary products and wet wipes. Yes, we have all read the label that tells us that they are ‘flushable’ but that does not mean that they will break down in the sewer. They are not always biodegradable and will get caught up in any pipe line that is not 100% smooth. See ‘relining’. They should not be flushed down the toilet but put in the bin.


This particularly important if you are not on mains drainage as these items will not break down in the Septic Tank or Treatment Plant.

Another problem is grease and fat. We think that if we emulsify our cooking fat in hot water and a detergent is alright to pour it down the sink. This is probably O.K. for the grease left on our plates and dishes etc but not for the fats that we have left in the pans that we have used for cooking our food. This should be disposed of separately. If you think that hot water will flush away the fats you are wrong. The hot water will only retain its temperature for a few feet into the drain line before cooling down and allowing the fats to solidify. This will eventually build up and slow the flow all the way through the pipe. This also gives the sanitary products and wet wipes something to cling too.

Blocked drain

It is advisable to avoid problems to have your drain line cleaned by high pressure water jetting on a regular basis, say every five years. This will ensure there is no build up of grease and fats and coupled with a CCTV ‘look see’ camera it will inform you of any potential problems or damage in the drain line, such as ‘root ingress’ or ‘cracked pipe’ etc. Apartment blocks should have an annual maintenance contract for the above.






Recently we had a call from a person who moved into a newish house out in the country. It was not connected to mains drainage and had a treatment plant installed when built. During the building the site should have been examined by both the local area building inspector and the NHBC who take over the builders insurance after two years. Also the Environmental Authority who would issue a Certificate of Exemption for the right to discharge the outfall from the treatment plant.

This person’s concern was that the treatment plant was ‘sinking’ into the ground and was afraid that it would damage the surrounding pipe connections. Obviously this would be the case, it would seem that the plant had not been set on or surrounded by concrete and required. After some discussions it was also established that the outfall was being discharge into a concrete ring soakaway which has been illegal since 1983. It should have been directed to a land drain in the absence of a ditch or water course.

It would appear that we cannot rely on the knowledge of our inspectorate, which in many ways is understandable as there are so many new rules and regulation appearing daily. They can’t be expected to be aware of them in all areas of expertise that they have to cover.

This property will have to be referred to all the persons concerned and could take several months to resolve. In the mean time just think of the disruption and the cost, both mentally and physically, to the home buyer who thought that they had purchased a recently built property and therefore would have no problems.

A structural survey that most of us have done before purchasing a new home does not normally include a full CCTV inspection of the drain lines. The surveyor will just lift the covers and check visually for any signs of defects.

When purchasing a home do have a survey of the drain lines and ancillary services,  it could save you money and heart ache.
