Hydro Cleansing Ltd is the leaders within the industry for carrying out professional sewer services, including Fatberg removal, helping to ensure that the nations waste water infrastructures are maintained, kept environmentally cleansed and more importantly flowing. You could call us the Fatberg busters as our fully trained expert engineers, most powerful Super Combination Tankers, and in some cases, our highly sophisticated water bound drainage camera Mega Float, trawl through the grime, glug and sludge to ultimately break down and remove fatbergs found in sewers.
What is a Fatberg?
Fatbergs are large congealed lumps made up of fat compounded together by oil, grease, sanitary items, wet wipes and other waste solids, congealed to sewer walls. Fatbergs have been found to grow to the size of a wide body jumbo jet, in other words, a Boeing 747 aircraft which ultimately block major networks resulting in major damage to sewer pipes.
Having been involved in projects which have seen us remove fatbergs, there is no doubt that fatbergs have become an increasingly common problem affecting the UK’S sewer networks. With fat, oils and grease (Fogs), sanitary products and wet wipes being poured and flushed down drains and pipes, and as reported earlier this year, plastic micro beads found in shower gels, facial scrubs and tooth paste are also proving to cause problems for our drainage systems.
Can Fatbergs really be turned into Green Fuel?
While fatbergs are problematic to sewer systems, fatbergs and sewer sludge have now also been recognised as a source of bio oil fuel –
Green Fuel. With fatbergs becoming ever challenging, experts have noted to find ways to turn sludge into between 25% and 40% of bio diesel. Bio diesel has also been recounted to be 80% cleaner for the environment than regular diesel, with the expectation that water companies might be able to find a use for the thousands of tonnes of waste found deep below the ground.

“On the fifth day of Christmas,
my true love sent to me,
five blogs in one,
four broken pipes,
three Septic Tanks,
two feet of tree roots,
and Hydro Cleansing’s Mega-Heat…”
Seeing as we didn’t post any blogs for you on the weekend, we are delivering a crate load of case studies to catch up! Not one case study, not two case studies, but FOUR CASE STUDIES! So sit back, relax, and read on!
The description of the job was pretty mundane. Can you send along a combination unit to empty out some drains which would in turn allow the contractor to handover their works to their client; a local hospital. Straight forward enough you would say. Anyway, circumstances conspired to result in Megatron attending the job, and as it turned out, that was definitely a good thing…
Megatron instantly began to recover vast amounts of rubble and other unknown items from depths of over 50m. The rattle of debris shooting up the suction boom and into the main hold continued, with Megatron pumping back/recycling waste water.
Stopping temporarily we identified what was still lying in the sewer, examined the filters in Megatron and carried out an inspection to make sure the sheer volume of coarse material hadn’t taken a toll on Megatron.
Megatron continued to show its capabilities and finished the job with no issues or problems whatsoever. Site management were horrified identifying the extent of the material found, which was there before they had started work.
Our client had to carry out some repairs to a waste pipe which was serving a local school. The client knew where the repair had to be completed and was also aware that there were a number of other services running within the immediate area but had no specific plans or guidance on location. Using traditional technology would have meant that the work could not be undertaken until the school was closed for at least two weeks, as the services feeding the school would have been destroyed doing the excavation.
Megatron was deployed. Using our on board ultra-high pressure water jetting, combined with Megatron’s powerful vacuum system, a trench measuring 80 metres in length, by two metres in width and two metres in depth was cut and vacuum excavated from site. The job took a total of three working days and the services remained intact leaving the school operational throughout.
Quick & Dirty
Our client has a large culvert within their manufacturing site fed by a series of drains spanning the entire thirty acre estate. The culvert had become heavily silted up with an environment agency requirement for a complete empty and clean due to the potential presence of hydro-carbons in the system. The previous contractor had used a system of excavators, scaffolding and bulk carriers completing the work in around five weeks.
Megatron attended site with two supporting bulk tankers and a range of peripheral equipment to support the various stages of remediation. Using the vacuum pump on Megatron, we extracted the contents of the culvert and directly transferred them from Megatron into supporting bulk tankers which then took the waste off site for treatment and disposal. Having exposed the layer of silt which extended to a depth of over a metre, We then used the waste water recovered from the culvert to power Megatron’s bulk jetting system which both broke down the silt and converted it into a slurry for extraction and disposal. These operations were performed simultaneously. This process was completed, the feeding drains jetted and cleaned (including the removal of concrete waste) and the site returned to our client within seven working days.
Business Continuity @ Canary Wharf
The call came at lunchtime one Friday. Our client had a blockage in their drainage system which could not be specifically traced but was creating a need for toilet blocks to be closed within their twelve storey building and people to be redeployed to other adjacent locations. Their system was perceived to be generating a build up in pressure, and as it was routed via various critical facilities including the plant room housing the uninterrupted power supply, a solution was sought urgently to prevent closure of the building a series of consequential financial impacts to the business.
By 19.00 hrs that evening a team was deployed with a range of equipment including Megatron as the centre piece. The team worked their way through the network of drains including the vast stack pipe supporting the whole side of this building which had a history of these issues dating back several years. Accessing the network at various points and applying a combination of Megatron’s vacuum pump and high pressure jetting operating at distances of over 300 metres, the building was eventually cleared by 02.00 hrs in the morning. We were able to demonstrate this by applying Megatron’s vacuum pump to the base of the stack pipe and systematically emptying toilets via suction from ten floors above. The building has had no further problems.
Clearly Megatron is a step outside the normal expectations of the market, but so are the results of the work undertaken. We certainly recognise that Megatron is not designed to compete financially with companies focused upon the rate per day as obviously the cheaper and less specified vehicle will always win. But for those clients out there, that recognise the full financial consequence of lost productivity, and the opportunity to reduce maintenance spend by achieving new levels of cleanliness, there is no match to Megatron.
“On the second day of Christmas,
my true love sent to me,
two feet of tree roots,
and Hydro Cleansing’s Mega-Heat…”
Continuing our twelve day countdown to Christmas, today’s blog is a nice juicy case study! However, this isn’t just any case study, this case study features blocked culverts, four foot long tree roots, over 50 TONNES of silt, and of course, an expert team of Hydro Cleansing engineers getting the job done.
Back in the Summer we were called out to deal with some blocked culverts, syphons and silt traps by the NPL. On our arrival it was clear that there was something seriously big blocking the syphon under the railway, even our camera couldn’t travel underneath to get a clear picture. Upon further investigation the engineers discovered that the blockage was clusters of tree roots growing through the tunnels. Check out the full scope of works below!
Client – National Physical Laboratories | Kings River Outfall Desilting
Scope of Works – Desilting of culvert | Root cutting in syphon under railway | Desilting of silt traps
- The culvert in Normansfield Road had a high level of silt and elevated water level, the camera was then unable to return a picture of the internal condition of the pipe. We needed to remove this silt and reduce the flow during the survey, we then proposed to undertake this with a super combination unit taking one day to complete and resurvey.
- The syphon under the rail way had root ingress which prevented the passage of the camera, to remove this we needed to reduce the flow through the culvert and use high pressure root cutting with specialist root cutting nozzles suitable for large bore pipes. We took one day to complete and resurvey.
- The silt traps in five manholes needed de-silting, they contained an average of 1m of silt each. The silt traps are 2.5m in diameter which will yield approximately nine tonnes each. We took two days to complete.
Check out those roots! Job done!
