ocre ferreuse

In the spring, many new home owners notice the presence of coloured water and deposits in their basement sump pumps or inside drainage pipes. These signs may indicate the presence of iron ocher, commonly called "iron bacteria."


Ocher deposits are a viscous residue resulting from a biochemical reaction caused by the presence of iron, water, and oxygen in the soil, sometimes combined with reactions of certain bacteria.

In some cases, this orange sludge develops in the foundation drain, which can clog, and in the sump pump located in the basement of the property, often causing damage to the pump. There are a number of consequences, and the solutions are often ineffective.
