Can You Modify A Cold Water Storage Tank?

Yes, you can. GRP water tanks can be modified, repaired and relined to prolong their life. In this blog, we’re going to outline popular modifications carried out on cold water storage tanks and highlight the benefits of modifying a water tank rather than replacing it.

Cold Water Storage Tank Modifications

There are several reasons why your GRP cold water storage tank may need modification. Perhaps it does not conform to the strict HSE guidelines on confined spaces. Or maybe it doesn’t offer safe access for people to carry out maintenance and inspections.

Whatever the reason, Cold Water Storage will have a solution for you. Here are popular cold water tank modifications we carry out:

Installations Of Access Manways

Having low-level access manways installed will enable safer and easier access to your water tanks for maintenance and regular cleaning.

Check out this case study where we replaced two side panels with two new panels containing integrated access hatches. Beforehand, the GRP tank could only be accessed via a top manway, which the client felt was unsafe for the team.

Replacement Of Roof Supports And Tie Bars

Roof supports and tie bars can weaken over time due to the environment they are placed in. This can compromise the structure of your tank and lead to significant problems further down the line.

By repairing and/or replacing roof supports and tie bars, you are ensuring your cold water tank remains structurally strong. Plus, repairing a cold water tank is often much more cost-effective than replacing it with a new tank.

Change In Water Tank Capacity

If your cold water storage tank isn’t the right size, it won’t be fit for purpose. But that doesn’t mean you need to replace it with a new tank. Where possible, your tank can be modified. At Cold Water Storage, we can modify your GRP cold water tank to increase or reduce the water capacity.

Installation Of Booster Sets

Booster sets are excellent devices used to effectively maintain water pressure. They cleverly recognise low water pressure and flow rate and work to increase the pressure. Booster sets are popular in buildings where there is insufficient water pressure or flow.

Benefits Of Cold Water Storage Tank Modifications

As you can see, there are several ways your existing cold water storage tank can be modified to ensure it is fit for purpose. Modifications can improve your water tank whilst prolonging its life.

In addition, water tank modifications are the more affordable and sustainable option. You don’t have to pay for the expense of a new tank installation.

If you choose Cold Water Storage for your water tank modifications, we will manage the project from start to finish. Our experienced project managers will spec out the work and develop Risk Assessments and Method Statements. They will also provide you with a timetable for delivery.

Upon completion, our team will issue signed paperwork and a full completion report with photographic evidence. This gives you peace of mind that the work has been carried out to the initial specification.

Other Cold Water Storage Tank Services

Aside from cold water tank modifications, we also offer a range of other water tank services, including:

Repairs And Reline

Instead of replacing your cold water tank, we will aim to provide a more sustainable and affordable option, such as repairing and relining the tank.

As long as your water tank is structurally sound, we can carry out repairs before relining it with a WRAS approved solvent-free polyurethane coating specifically designed for relining potable water tanks.

This solution addresses issues such as deteriorating mastic, erosion, corrosion of internal steel fastening and bacterial growth.

Tank Cleaning And Disinfection

If your cold water tank is not meeting hygiene standards, it could cause serious harm whilst putting you at risk of legal consequences.

To be compliant with water hygiene regulations, your cold water tank must undergo rigorous risk assessments and any problems found must be dealt with quickly and efficiently.

At Cold Water Storage, we can carry out risk assessments and provide the service needed to ensure you meet hygiene regulations. This could be something as simple yet crucial as a tank clean and disinfection.

Legionella Services

Cold Water Storage also offers Legionella prevention services to ensure that any risks are properly managed to comply with the law. These include:

  • Description of the system
  • Training of key personnel
  • Identified potential risk sources
  • Means of preventing the risk or controls in place
  • Monitoring, inspection and maintenance procedures
  • Records of the monitoring results and inspection checks carried out
  • Full schematic diagram of the water system in place
  • Arrangements to review the risk assessment regularly
