Thomas Tunnock Limited 

Nicholson plastics had the pleasure of working with Scotland’s largest bakery company the Thomas Tunnock Limited in 2016, our production team manufactured and supplied a potable cold-water storage tank for their office building.

Due to further development and expansion, their engineers got in touch with our sales team for an additional water tank, this time to supply potable water to the new extension works which were planned for their main factory located in Uddingston, Glasgow.

Our Clients Water Storage Requirements

Tunnock bakery was undergoing renovation and expansion works and the space allocated for the tank needed to be reviewed. The old water tank covered a floor footprint of 48 cubic metres, the objective for the new tank installation was to reduce the space required for the tank without dropping the holding capacity, the existing sized tank would not fit into the new layout of the factory floor, space was at a premium.

Our external team attended site to meet our client’s engineers, in order to understand their specific requirements, it was important to meet on site to discuss the scope and possible restrictions/obstacles of replacing the water tank.

GRP Water Storage Tank Solution

With our knowledge and expertise, the team decided on building up rather than building out. Floor space was not available but there was enough space vertically to build allowing for the same holding capacity required to support the building’s requirements.

The existing tank was an 8x6x3m sectional tank. With the new design for the extension works the floor space needed to be reduced by approx. three meters for the works to go ahead, while keeping the overall capacity of 130,000 litres.

Our team decided on a 4meter high tank with 6.5meter in length and 5meter in width, but rather than using these dimensions to replace the existing length and width our engineer switched them around so the new tank would allow Tunnocks to demolish the existing three piers creating enough space for their extension works.

After stripping out the old tank our team got started with the new 6.5x5x4m sectional tank with a ball valve box to get the maximum capacity of the new tank of 130,000 litres. With the tank, already being raised on both piers and secondary support steels the overall working height increased to 5 metres high. This height increase was factored in with our engineers, sufficient space was available after the tank supports were put in place. Due to the huge footprint of the tank, we recommended a side access hatch and two internal ladders to help with any future maintenance of the tank.

Space restrictions on the site are standard for many city developments, Nicholson Plastics team have a wealth of experience in this area having manufactured, supplied and installed sectional water storage tanks for over 40 years. Our team have worked on numerous urban development projects where maximising space is the key objective. Optimising available space without sacrificing storage capacity is an area our team specialise in. We cater for projects of all sizes and pride ourselves on creating water storage solutions for projects where space is restrictive.

Our mission: To help you find the most cost-effective solution for your water storage requirements.
