Sectional Steel Tanks

COVAC Case Study

Client: NHS - Hospital in the South East
Project Brief: The Internal Preparation & Coating of 1 No Sectional Steel CWS Tank/2 No Compartments
System Specification: Acothane DW Solvent Free Polyurethane
Completion Date: 2015
Guarantee: 10 Years
COVAC Contract Ref: 1283

Located in a dedicated plant room, the structure supplies all potable water supplies to the hospital. It is a twin compartment, sectional tank constructed from 1000mm x 1000mm galvanised, mild steel pressed panels.

The total size of the tank is approximately 7.0m long x 5.5m wide x 3.0m high and has an internal sectional, steel, divisional wall which splits the tank into 2 No. compartments, each sized at approximately:- 3m x 7m x 3m and 2.5m x 7m x 3m.

The internals of the steel substrate had been previously coated with a bitumen paint which should no longer be used in potable /drinking water tanks due to their carcinogenic properties and high solvent content which can leach into the water putting users at risk of serious health issues. This existing coating had started to de-bond from the steel substrate resulting in significant corrosion providing nutrients for harmful bacteria such as Legionella.

Testimonials

Covac have carried out a professional and extremely excellent treatment of our on site bulk water tank which now will allow this tank to be utilised for a number more years.

Covac are one the best companies i have worksed with and their works are first class.

Yarwood, Lee
Covac undertook the task to 'reline' one of our hot water tanks, roughly 5m x 5m x 4.5m. This involved blast cleaning the tank, then applying epoxy lining to the tank.

The Covac team on site were fantastic, they dealt with issues that occurred efficiently & worked through the task quickly & professionally.

Parr, Ashley

Yet again Covac has proved their skill and expertise in meeting problems head on and resolving them within the agreed programme, despite a much larger scope of works! Thanks again to the whole team on site and in the office for making a very difficult task stress free - Highly regarded expert team and 110% recommended to anyone looking for tank refurbishment/relining works.
