Summary Of Works

A treatment plant comprising of 7 No. vessels varying in size with associated steelwork including stairs, railings etc. each sized as follows: Pumping Tank - 1.8m x 2m diameter Oil Separation Tank - 1.8m x 2m x 4.5m Round Tank - 2m x 2m diameter Balancing Tank T3 - 7m x 7m diameter Sludge Holding Tank T5 - 4m x 2m diameter Clean Water Tank T10 - 2m x 3m diameter Pumping Tank T8 - 2m x 3m diameter

The majority of vessels & steelwork were showing signs of corrosion at various stages, which not only looked unsightly but if left untreated could lead to certain tanks developing leaks. The Client required a guaranteed, long term solution to not only look aesthetically pleasing but also to externally protect the tanks against corrosion and leaking. COVAC prepared, repaired the tanks and applied an external tank coating to all tanks and steel work. The Client then received a ten year guarantee with the option to extend the guarantee after ten years.
