Water Tank Modification & Repair

Cold Water Storage offers a variety of services to modify, refurbish and make improvements to your GRP water tanks. We plan this work in the same way we do our water tank refurbishments and replacements.

We manage the water tank modification project from start to finish with our in house project managers who spec out the work, develop Risk Assessments and Method Statements as well as a timetable for delivery.

Once the project is completed we issue signed paperwork and a full completion report with photographic evidence so you can rest assured that the work has been carried out to the initial specification. Here’s a selection of the water tank modification services we offer:

Installation of Access Manways

We retro fit low level access manways to allow safer and easier access to your water tanks for maintenance and regular cleaning.

Roof supports and Tie Bars

We can repair and replace water tank roof supports and tie bars to ensure the internal integrity of your tank remains structurally strong.

Change in Water Tank Capacity

We are experienced at water tank modification to increase or reduce the capacity of your water tank to ensure it is fit for purpose.

Booster Sets

We can install, service and repair booster sets to improve the water pressure at your site.

Tank Cleans and Disinfections

We are fully trained and qualified to carry our domestic and industrial tank cleans and disinfections on your water tanks, water towers and mains pipework.

All Services


From the the moment we start working with you we are dedicated to the accurate assessment and planning and delivery of the project. We have a very efficient turnaround; and are accurate with the estimation of the length of project.
