Replace or Refurbish? (Replacement Advice)

Most engineers who replace their steel water storage tanks for brand new Glass Reinforced Plastic (GRP) water storage tanks believe that this is the ‘ultimate’ solution. Unfortunately, having now repaired and relined literally hundreds of GRP water storage tanks, we know this not to be the case. COVAC are constantly asked to carry out water tank repair and reline GRP water storage tanks, some of which are only months old. This is because the problem faced by all engineers who are responsible for the maintenance of GRP tanks is that even with regular cleaning and chlorination, bacteria such as micro-aquatic organisms will continue to multiply as they are protected in the habitat provided by air filled cavities and fine cracks that often cannot be seen with the naked eye. These cavities and cracks in the internal substrate allow bacteria to nest and proliferate.
