Corroding, Non-Compliant Water Tank

Our guys at Cold Water Storage have refurbished a number of corroding water tanks in our time and know what is required to ensure you are fully compliant with the water tank legislation. This particular clients water tank was corroding pretty badly and we were called out to fully audit and reline the tank to make it compliant.

We were asked to reline this water tank for our client. The tank was corroding and non-compliant and it was due an inspection after not having one for over a year. This GRP water tank was pretty large and would require a lot of work in order to make it compliant. We sent out 4 guys from the team to start work on the water tank with the aim of having it complete before the Easter Bank Holiday. A water tank that had corroded like the one in this particular case can be potentially dangerous not only because of the potential of leaks but the water can also become more prone to infection.

After carrying out the audit and seeing which would be the most viable option, our water tank replacement team decided that the tank wouldn’t need replacing and could be relined without the client having to spend too much money on a brand new tank.

The work was undertaken in less than 4 weeks, including shot blast preparation and the application of a 2 pack lining system approved for potable water (stripe coat and 2 full coats). With the tank being so large and as such the coating had to be planned carefully by our 4 man team to ensure the correct adhesion between the first and second coats. Both first and second coats had to be applied less than 24 hours apart and applied in agreed sections.

Overall, our guys were happy with the final outcome of this particular relining project. It passed its subsequent audit and the client was delighted with the speed of the work and the quality of the final project. Is your water tank compliant?

Non-Compliant Concrete Water Tank

Last week we surveyed a non-compliant concrete water tank on the roof of a West Yorkshire museum. The client wanted either a new tank or a tank reline to comply with ACOP L8 requirements for water storage. We sent out a team to take a look at the museum and to see what work would be needed. Once our team arrived on site, they ensured that the surrounding area was closed off and they carried out the necessary auditing process.

 

The team came to the conclusion that it would require a tank replacement or reline that would ensure it was made compliant. This also meant closing the museum for a short period of time. The museum is a nonprofit organisation so they needed us to be as competitive as possible. This meant providing the museum with a price that is reasonable as well as being efficient with our work and ensuring that the museum was reopened as quickly as possible. Based on the location and sound structure of the tank we recommended a tank reline as this is more cost effective and less impactful on the site. This ensured that the museum would be back open as swiftly as possible and our team got to work that same day.

Our team have years of experience and have worked on a number of public areas where they have to be closed for a period of time, which we understand. We ensure that every job is carried out to the best of our ability whilst remembering that these companies have a business to run. We take pride in ensuring that every tank replacement is done to the best of our ability as well as keeping it as cost-effective as possible for the client.

Overall, we are happy with the final outcome of the water tank and felt happy enough reopen it to the public. The guys at the museum were shocked at how quickly we were able to carry out the job and we were delighted at how well everyone worked on that particular job.

Booster Pump Installation

When the building’s tenants started complaining of very poor water pressure in their apartments, particularly the top floor apartments, Cold Water Storage was asked to survey the building and diagnose the issue. After completing a very thorough investigation, we were able to explain to rule out blockages and confirm that the mains water pipe was not suitable for feeding the higher level apartments with the pressure required.

We then took into consideration all possible options and arrived at the best solution. We determined that a break tank with a booster system would provide the desired water pressure for the top floor apartment residents.

Pipework Installation

Pipework was cut into the plant room and a mains bypass was installed. A cold water vessel holding 1000 litres of water was erected and then plumbed into a three pump booster system.

This was then plumbed into the buildings pipework manifold. Once we commissioned the new tank and booster set we were keen to hear from the residents who had complained of poor water pressure. They told us that they had noticed an immediate increase in pressure as far as the top floor apartments.

Finding Sustainable Pipe Solutions for Clients

This set up is also designed to ensure that the building occupants never have water disruption even when planned maintenance occurs on the booster system and tank. Chris, Director of CWS and project manager on this job is pleased with the outcome, ” When I heard from occupants who had to endure low pressure and struggled to have good powerful showers in their own homes, I really wanted to find a solution.

To hear the genuine relief and thanks for fixing the problem it makes the job so satisfying. I think this may be a common issue in some high rise buildings so now we have the solution it is good to share this across the industry.”

Leeds Shopping Centre Water Tank Upgrade

This particular job involved our Cold Water Storage team going out to replace a large water tank in a shopping centre. The tank that was there prior had not been replaced in over 20 years and was in desperate need of an upgrade. We sent a team out to Leeds to evaluate the current water tank that was in place and audit the current state of it.

Evaluating the Current Water Tank in Place


The audit found that the water tank had had no work carried out on it for 5 years and was long overdue an evaluation. We called out our legionella services team to deal with the situation, clean the current tank to eliminate the risk is legionnaires disease in the current water tank. Once this had been carried out safely, our team then got to work on replacing the tank and fitting a brand new one there in its place. This ensured that the shopping centre was safe for its employees and everyone there.

Leaking CWST Panel Replacement

Leaking CWST Panel Replacement

Our water tank replacement team here at CWS was asked to replace a panel on a sectional GRP water tank at a hospital. It was vital that we had a team sent out right away to deal with the problem in order to cause as little disruption as possible.

The panel, which was situated on the tank divider wall and was fractured, required replacing. It was the cheapest and most effective option available. We looked at ways in which we could mend the wall but for the work required to try and save the same wall, it would not be efficient for our team. We had a replacement sent over and ensured that the work was carried out as swiftly as possible.

The work was carried out overnight, removing any water service disruption issues. Our team worked really hard to ensure that the replacement and audit were carried out as quickly as possible. The team we liaised with from the hospital were delighted at the efficiency and duty of care we took when carrying out the work. We were able to ensure that the water tank was safe and passed every audit once the work had been completed. Our management team were over the moon with the speed and quality of work and for such a big client, we were happy that we could deliver and over exceed all expectations.
