Hydro Cleansing are launching their newest vacuum tanker TERMINATOR at the CV show on Tuesday 26th April. It’ll be the largest vacuum tanker on the largest Scania Chassis ever built in the UK. It’ll be taking on the largest wet waste disposal projects in Europe!
With the Super Sewer being built in London to take over from Bazalgette’s revolutionary sewer system built in the 1850’s, there is a need to develop efficient ways to maintain this incredible feat of engineering. Super Combination Vacuum Tankers currently fulfil this role and these are few and far between. With the Super sewer having depths of up to 100m, the majority of these tankers will need to evolve, to manage the risk of flooding to these sections of the sewer.
Vacuum Tankers themselves have been round for over two centuries. The first of them was an awesome step forward in Georgian engineering. The Georgians created a vacuum on horse drawn trailers; the most well known of these was a Merryweather vacuum tanker.
In simple terms Vacuum Tankers draw up liquid waste by creating a vacuum within a tank.
Hydro Cleansing, based in Croydon, have been at the forefront of the innovation of these units for over a decade.
Megatron, built in 2010, was a revolutionary vehicle. It was the most powerful vacuum tanker at the time and many questioned whether it would work. It surpassed every expectation. Jobs that would have taken weeks, took days.
Normal combination tankers have a mechanical pump rotary vein. Hydro Cleansing’s super combination tankers feature liquid ring vacuum pumps to ensure a powerful vacuum is maintained. What is required of the unit varies but for the toughest pump station empties Hydro Cleansing’s Megatron unit can move 6000 cubic feet of air per minute. This creates astoundingly efficient and powerful vacuum suction.
The newest vacuum tanker on the block is Hydro Cleansing’s Terminator, being unveiled at the Commercial Vehicle Show, week commencing 25 April, at the NEC in Birmingham.
Terminator is an international collaboration. Built and designed in the UK, on a Scania Chassis and with Kasier parts, it again raises the bar for vacuum tankers and increases the potential for future construction projects.
The Super Sewer’s maintenance will be catered for as well as other similar projects throughout Europe by Hydro Cleansing’s Terminator. It continues the innovation within the Drainage Infrastructure established by Bazalgette over 150 years ago.
The volatile issue of water management is under review. Flood prevention strategies are being drawn up by DEFRA but in the meanwhile what we can do is maintain the framework that is in place and make it as effective as possible. Clearing soakaways and gullies, developing new flood prevention and maintaining the sewers all contribute to keeping Kent safe. Kent has been dreadfully affected by the winter’s flooding. Hydro Cleansing is proud to have been there 24/7 clearing the flood water and keeping homes safe. Hopefully as Spring approaches the flooding will lessen.
HCL, on behalf of Amey, are providing the backbone of drainage maintenance in the valleys of Kent. Some HGV drivers would fear to drive in the tracks of our HGVs, for fear of getting stuck at the bottom of a hill. Hydro Cleansing’s experienced engineers had no such trouble. We are determined to continue to maintain Kent’s infrastructure.
One of today’s jobs was to clear a soakaway and dispose of the waste.
As the lambs skipped, the rabbits ran and the pheasants dithered in front of the vehicles; HCL’s tanker made its way safely to the soakaway’s location. With the covers removed, the vacuuming and jetting began. The surface waste was taken away by vacuum suction. Once the remaining waste was of a density that could support a person; the engineers prepared for the confined space work. The engineer who would be entering the soakaway readied himself. He was secure in the dry suit. He wrapped the harness around his legs and arms and across his back. Prepared and up for it, he was attached to the winch and the Top Man began lowering him into the confined space. As he was lowered into the soakaway the harness held him tightly and a moment later he was knee deep in the sludge.
He directed the suction hose and jetted the weep holes. High pressure jetting loosened the silt and allowed it to be vacuumed away. An hour and a half later the soakaway was cleared. 7 tonnes of waste had been loaded onto the tanker for disposal.
The weighted tanker drove steadily up the hill. Its chevrons gleamed in the lessening afternoon light as the gradient of the hill challenged its might. The tanker safely cleared the valley and took its load back to HCL for tipping into the waste treatment plant.
With professionalism, efficiency and determination the engineers delivered the results. You have to see the incredible power of our tankers to believe what they can do.
Today we have important American visitors from Rain For Rent. This company is a leading provider of temporary liquid handling solutions including pumps, tanks, filtration and spill containment. Their projects range from flood relief to construction site dewatering, sewer bypasses and industrial plant turnarounds. The company is known for its systems engineering expertise and its ability to tackle complex jobs cost effectively. Family owned and operated since 1934, it serves all 50 states of the USA, Canada and the UK from more than 65 locations.
In honour of them we’re celebrating Pi day! The American calendar reads today as 3.14, the initial figures of Pi. It is the crucial mathematical constant ratio between the circumference of a circle and its radius. Circles are a key element in the construction of our cylindrical tankers. We also have a cyclical nature to our wet waste management.

Our innovative tanker Megatron has an elegant cycle which allows for continual work. The beast vacuum sucks in wet waste its recycling unit sifts the water from the other elements of the waste and uses it to continue its high pressure jetting.
The water cycle is a beautiful thing in nature. We contribute to its fluid movement through modern life, in keeping sewers flowing, recycling waste water and much more. As people innovate, water is used in increasingly innovative ways. From harnessing its power to employing it in construction; it is essential in almost any endeavours. Society squeezes every benefit out of water, and it is often left as waste: sludge, slurry, faecal waste etc. At Hydro Cleansing we take these waste products and return them to purified water.
The water cycle flows through both of our businesses and HCL puts it back into its pure form.
