A complete disaster
This is typical of a sewage treatment plant that is undersized. It is also typical of a plant that has not been serviced or de-sludged. The multiple owners of this unit should be very concerned.
This hole appeared in a garden as a result of poor and insufficient backfilling when the septic tank was installed! You can see the neck of the unit in the hole. Concrete may be expensive, but not as expensive as this repair!
This drain has been laid much too close to trees which have flattened the pipe as the root grew. The drainage pipe diameter is now too small to allow sewage solids to pass, or to rod the pipe. The only solution is to either re-lay the drainage pipe to avoid the tree area, or to remove the trees, neither of which is a cheap option. Did the Contractor not know that drainage pipes must NEVER be laid within tree root zones or was it the easiest option for him?
|Oh Dear - The first sign of trouble|
|The Problem - Roots entering the drainpipe|
|The Culprit - 30 metres of root-blocked drains and the drainpipe is the wrong type! The pipe is for LAND DRAINAGE only and must not be used for foul sewage|
The above is a photo of a CORRECTLY operating Primary Settlement Tank in a 3 stage sewage treatment unit. The UK's leading brands are these 3 stage types! As you can imagine, Primary Settlement Tanks do NOT tend to be odourless unless vented correctly - which is not usual with UK systems! This unit had been installed next to the purpose built barbecue area causing it to be unusable in Summer!
A fat blocked drainage pipe leading to sewage treatment unit for a cafe. The installer 'forgot' to install the grease trap!
This drainage installation is far too near to the house!!! The excavation dangerously risks undermining the house foundations, as land can 'slump' at a 45 degree angle from the bottom of the hole! If this happens here, the house wall will fall in! It is also under the minimum distance allowed under UK Building regulations of 7 metres from a dwelling! It proves that some Contractors either don't know or don't care!
Above is a photo of a Klargester Alpha septic tank installation which is wrong. No concrete was used, just gravel base and backfill and the tank had a high chance of cracking when full. Luckily, we were called in early enough to stop the installers who had to remove the tank and start again. Why do they call themselves 'Professional installers'? If you want to find the installation manual, look in the bottom of the skip for the unopened envelope!
These are a popular make of low-profile septic tanks which were installed in high groundwater sites. They all had to be replaced as they distorted with the pressure. Buy the best quality tanks that you can afford - it is cheaper in the long run.
This ia a Conder ASP 6 after a tractor ran over it. A car would have caused similar damage. He sent us the photo to see if we could repair it - the answer was NO. Never install a sewage plant in a trafficked area.
The above photo is of an old 'Thorpecrete' trickling filter sewage treatment plant. You can see the tipper tray submerged on the right and the distribution channels running from it are also under water. The plant has its outlet at the bottom, about 1.5 metres below ground, so there should be no liquid in the tank. The grey colour of the water is typical of the septic tank effluent that is discharged into it.The filter media, which is composed of stone chips, has become clogged and the soakaway drainfield is also blocked. A totally new system is required. Thanks to Mr.P. D. for permission to use the photo.
This is the effluent discharged into a ditch from an illegal 'In-Tank septic tank conversion unit. No wonder they are illegal!
This is the photo that you want. A clean sample from a well designed, well installed and well maintained sewage treatment unit and drainage system.
YOUR drainage problem OUR drainage solution.
Sometimes these effluent discharges are from older types of sewage systems that have fallen into disrepair, but often they are from modern sewage treatment systems and plants that are only a few years old! Sometimes it is because the sewage system and drainage has been poorly designed or not maintained regularly, but quite often, it is the SAME brand of sewage unit with the SAME problem, or the SAME drainage contractors who make the same mistake over and over again! 90% of our drainage surveys reveal at least one installation mistake!!
Some of the most problematical sewage treatment units units we come into contact with are made by some of the most well known Manufacturers, some of which only have a 12 month warranty! A household name does NOT guarantee a reliable, robust product, a lot depends on the drainage and tank installation.
