What Is Cold Water Tank Modification?


Cold water tank modification is the process of having a cold water tank modified or refurbished to ensure it is in full working order and compliant with all rules and regulations.

Your buildings cold water tank is responsible for hygienically storing potable water. There are various types of cold water tanks, including steel water tanks, concrete water tanks, galvanised steel water tanks and GRP cold water tanks.

Most of these types of cold water tanks are designed to last 25+ years providing they are well maintained.

However, there may come a time when your tank needs repairing, refurbishing or modifying. This will usually prolong the life of your cold water tank.

In this blog, we are going to look at some of the common cold water tank modifications and share examples of modifications we have carried out in the past.

Common Cold Water Tank Modifications

At Cold Water Storage, we carry out cold water tank repairs, relines, modifications, refurbishments, replacements and installations. Common cold water tank modifications include:

  • Installation of Access Manways
  • Change in Water Tank Capacity
  • Booster Sets
  • Roof Supports & Tie Bars
  • Clean & Disinfection

Installation Of Access Manways

To maintain water hygiene and prevent contamination, which can cause disease and illness, cold water tanks much be inspected every 12 months.

A water hygiene risk assessment (also known as a Legionella risk assessment) should be carried out by a professional water hygiene specialist. Following the risk assessment, any maintenance or remedial work must be carried out ASAP.

However, to carry out the risk assessment and/or remedial works, a cold water tank must have safe access manways that comply with regulations.

Water hygiene specialists, as well as your own team members, should be able to access the cold water tank safely, without putting themselves at risk.

Similarly, your access manways should conform to strict HSE guidelines on confined spaces. With Cold Water Storage, your cold water tank can be modified to allow safe and compliant access.

Our water tank experts can fit retro fit low-level access manways to allow safer and easier access to your water tanks for maintenance, remedial works and regular cleaning.

Roof supports and Tie Bars

As long as your cold water tank is structurally sound, it can last for years to come. Even a 15-year-old tank can undergo repairs, relines and refurbishments to prolong its lifespan providing it is structurally sound.

However, if the structure of the tank is compromised, a replacement is the only option. And this can be costly, especially when compared to repairs or modifications.

Roof supports and tie bars ensure the internal integrity of a cold water tank, ensure it stay structurally strong and safe. At Cold Water Storage, we can repair or replace water tank roof supports and tie bars.

Change In Water Tank Capacity

If your cold water tank is too small, you run the risk of overflowing, leaks and other problems. If it is too large, it may take up much-needed space within your building.

At Cold Water Storage, we are experienced at water tank modification to increase or reduce the capacity of your water tank to ensure it is fit for purpose. If you are moving your cold water tank to a different area of the building, changing the capacity may be necessary.

Booster Sets

If poor water pressure is a problem in your building, it may be because the water pipes are not suitable for feeding water to various areas of the building. To fix this problem, Cold Water Storage can install, service and repair booster sets to improve the water pressure at your site.

Tank Cleans and Disinfections

To prevent the growth of bacteria, such as Legionella bacteria, which causes serious diseases and illnesses, your tank may require a professional clean and disinfection.

At Cold Water Storage, our team is fully trained and qualified to carry our domestic and industrial tank cleans and disinfections on your water tanks, water towers and mains pipework.
