Sewer hydrogen sulphide attacks

Mar 6, 2019

When Hydrogen Sulphide (H₂S) is found in sewers it can create a foul smelling ‘rotten egg’ odour, potentially hazardous work conditions for drainage crews and accelerate the corrosion of valuable water authority assets including causing damage to clay, concrete and pitch fibre drainage pipes as well as treatment plants, pump station wells and discharge manholes.

Hydrogen Sulphide is a dangerous gas which, at high levels, can cause loss of consciousness and even death. Corrosion in sewer pipes occurrs when hydrogen sulphide gas reacts with the moisture present on the sewer wall causing it to form a caustic sulphuric acid, which destroys concrete, steel, pitch fibre and clay pipes within wastewater environments.

Hydrogen sulphide is a colourless, flammable and extremely hazardous and can lead to extensive damage to metals including pitting and uniform corrosion.

Sewer pipes under hydrogen sulphide attack can be extremely fragile and wafer thin in sections, so conventional sewer cleaning methods with powerful recycling jet vacs can destroy what pipework is remaining and potentially cause is to fully collapse.

Wilkinson Environmental have developed bespoke jets combined with specialist sewer cleaning techniques to clean sewers and drains under attack from hydrogen sulphide without causing them to collapse.
