Sewer cleaning is something Hydro Cleansing are the go to guys for. Cleaning a London mainline sewer requires some complex logistics and expert engineers. From cranes, to penstocks, to 500m of jetting hose, this one required a specialist approach.
The sewer had to be cleared of silt in order to allow an inspection of the sewer to take place. The line was 20% full of waste and a risk assessment had established that the risk was significant enough to require all of the silt to be removed before the inspection was undertaken.
The sewer water was diverted by lowering the penstock which sent the flow of water through an alternative sewer. This penstock didn’t keep all of the water out and so the remaining storm water had to be continuously pumped away from the chamber where the engineers were working. This was 45m deep! A crane was supplied by the client to lower in the pumps and hoses.
From there our engineers could remove the silt and MEGATRON, the largest vacuum tanker in Europe, vacuumed it up the 45m into bulk tankers for disposal. MEGA REEL, the longest jetting reel available at 500m allowed the confined space engineers to jet as far into the sewer as they were required to. This loosened the silt and meant it could be sucked up the hoses at astounding speed!
The sewer cleaning was carried out during the night as the flow of waste water is lower. Without the awesome power of Megatron, the specialist hose of Mega Reel of the expertise and commitment of our engineers, this job would have taken weeks. It was completed in a few nights!
The dangers of flood water should not be underestimated.
It’s powerful and just 6 inches of fast flowing flood water can knock you off your feet.
But it’s not just its power that can be hazardous but also the pollutants it contains.
Each year in the UK we produce around 75,000 tonnes of human feces and 6 billion gallons of urine, with these figures rapidly increasing year after year.
Waste water from our toilets along with rain water mix together in sewage pipes underground, which lead on to wastewater treatment plants for processing.
Extreme rainfall can flood these pipes forcing dirty water back up spilling raw untreated sewage into our homes, straight out into our streets or into our rivers.
If your property is flooded you can’t just wait for it to dry out then move back in.
Any wood in the house, all furnishings and even plaster board on the wall will soak up the water, containing bacteria, so ultimately it all has to be removed and refitted.

Bag It and Bin It – Don’t Flush It
A water industry-led campaign Bag It & Bin It aims to educate people about what not to flush.
Toilets are only designed to take away human waste and toilet paper. Any other personal waste should be disposed of correctly as household waste.
This protects the environment and the UK’s waterways, avoids harm to marine life and prevents problems in the sewage system, which was not designed with this sort of waste in mind.
Items that shouldn’t be disposed of down the toilet include:
Plasters and bandages
Syringes and needles
Medicines and tablets
Below is a festive themed reminder of the points made above.
