The necessity of preventing oil from entering our natural environment cannot be understated. It is a lethal substance which can cause awful harm when not managed.
Interceptors are a key to the way we control the impact that our oil waste has on the environment. They collect oil from carparks, garage forecourts, industrial estates and anywhere where oil is a part of waste produced.
Styles of interceptor vary. They are installed beneath the ground and drainage from the site goes through its multiple chambers. As the oil sits on the surface of the water waste, it filters them using a pipe that is positioned below the level of the oil and therefore lets the waste water through. As the levels can vary there are generally three chambers and some have filtration fabric that sieves remaining oil from the water, eventually allowing oil free waste water out into the sewer system. Any solids in the waste are suspended at the bottom of the tank. They need to be emptied on a regular basis as the waste accumulates. Some interceptors have an alarm on them which goes off when a chamber becomes full.
One of our exceptional units then takes that and any many other types of dangerous waste to specialist hazardous materials disposal sites.
The oil is then disposed of according to the law.

We’ve been working on the Super Sewer, enabling the works to go ahead providing in depth CCTV surveys and cleaning.
Our engineers were down in Bazalgette’s original tunnel’s carrying out the necessary CCTV surveillance to enable the construction work to begin. Every crack and leak was recorded.
The surveys provided a level of detail that allowed the client to make necessary repairs within the existing rock. A stronger and safer system will be the result as they start works on the Super Sewers.
With the beautiful pictures of the grand super sewer and how the media have pitched it as a bright new dawn for London’s drainage, it would be easy to forget the ugliness of the job.
When our engineers were asked the question,“What was it like surveying for the Super Sewer?”
A typical response was, “Bloody horrible, to be honest!”
Walking through raw sewage is never fun. The necessary work we undertook, has enabled the construction of the Super Sewer for London to go ahead.
London is an incredibly beautiful city. That its sewage has been managed by a 150 year old system is an example of extraordinary Victorian engineering. The 21st Century’s contribution: the Super Sewer is taking on the mantle of keeping one of the world’s leading cities running clean.
The level of engineering required is astounding. Shafts over 60m deep will join existing pumping stations to the super sewer. The main treatment works will be at Beckton where the waste water will be processed and reused.
We can’t understate the impact and importance of the London Super Sewer. It’s a fantastic addition to the London sewer system, Sir Joseph Bazalgette would be proud.
Our tankers were up to some awesome team work yesterday!
Again we were out protecting our country’s motorways. The job was to clear a culvert of a build-up of embedded silt. The estimate was 30 tonnes of waste!
This was a large scale job involving a fantastic team and some of our flagship tankers. Our Super combination unit Rainmaker was there providing the hard core power for the operation. Our artic tanker which is nick named ‘Jack the giant slayer’ stored the waste that Rainmaker vacuumed. Another bulk tanker, our confined space team and a welfare unit made up the rest of the fleet.
Due to the nature of the waste, our team implemented a strategy of lowering the flow of water through the culvert to allow the confined space engineers into the space to shovel the shingle and silt into Rainmaker’s vacuum. They made a dam at the far end of the culvert and our combination unit was used to divert the remaining water flow from the culvert into a ditch beyond. It would naturally have flowed there from the culvert.
A 4” vacuum hose maintained the low water level allowing the confined space team access to the culvert. The larger 6” hose removed the large pieces of silt.
Our confined space engineers worked flat out to funnel the silt into the vacuum hose. You can see some of the silt is the size of golf balls. The vacuum hose sucked them away into our tankers.
Thankfully we have a welfare unit that we bring to these kinds of jobs. A warm kitchen, toilet and shower mean our engineers can have a short break on site and return to their work without much disruption. It saves driving covered in mud to the nearest greasy spoon for a cup of tea after shovelling mud for hours.
Good honest work was done! Preventative action against flooding was taken. Our work made the light at the end of the tunnel possible.
