Getting rid of those old tubercles

ENGINEERING - The story of cleaning old water pipes

The problem
The UK network of water pipes up and down the country, are of diverse age and condition, some from Victorian times. Even so, the quality of drinking water in is controlled by some of the tightest regulations in the world, with standards set by the European Union for over 50 different substances. Tubercles form as the result of corrosion inside steel and cast water mains and consist of layers of rust building up over time to form lumps and mounds. In addition there can be a build up of manganese and bio-films. These things are very difficult to get off the inside of the pipe.

The solution
This company have developed a non-aggressive process to clean and remove tubercles, bio-films and manganese which, unlike current methods, cause no damage, use significantly less water, create less waste in both dirty water and debris and operate at low pressures within increased levels of safety.
