Help, I’m losing 40L per day, per tank!
This client was frustrated after spending considerable money on at least three different expensive products in an attempt to repair the crack on his water tank. Watching the water leak out day and night was making them very anxious for their supply, especially when their second tank started leaking as well and they worked out they were losing at least 40L per day from each tank.
I felt a bit like an archeologist looking at the various goops applied to the outside of the tank in attempts to fix the leak.
Trying to repair concrete tanks from the outside often has very limited success. A tank wall typically has three layers, an inner and outer skin and a central layer surrounding the reinforcing mesh. You really don’t want water rusting the mesh because rust expands the metal and the concrete then quickly degrades.
A standard part of the repair work is to clean the water tank. In this case it was a huge bonus and there was very large and disgusting accumulation of things you really don’t want decomposing in your drinking water! Difficult to photograph, this is a mound 300mm high. Yuck!
