Water tank replacement recently completed at a health centre in central London.
The site two existing galvanised steel water tanks were overcapacity, which subsequently allowed for a very poor turnover of water.
This led to the water in both cold water storage tanks to become stagnant, and biofilm forming on the tanks surfaces.
Why Should Water Tanks Have a Good Turnover Of Water?
- Maintaining water quality: A good turnover of water ensures that fresh water is constantly introduced into the tank, which helps to prevent the buildup of pollutants and contaminants in the water. This is particularly important for water tanks used for drinking water, as the quality of the water can affect human health.
- Preventing bacterial growth: Stagnant water can promote the growth of bacteria, which can be harmful to humans and animals. A good turnover of water helps to prevent the growth of bacteria by introducing fresh water and keeping the water moving.
- Avoiding sediment buildup: Sediment can build up in water tanks over time, which can affect the quality of the water and reduce the capacity of the tank. A good turnover of water helps to prevent sediment buildup by keeping the water moving and preventing particles from settling.
Our Water Tank Replacement Solution
We initially consulted our client by recommending the most efficient sized storage tanks to be installed which would ensure the optimum turnover of water.
While also taking into consideration the very limited amount of access in the roof space.
The project was also made more challenging due to the access into the roof space being very restricted, which made it impossible for our team to install our regular sized water tank panels.
Therefore, the decision was made to utilise panels which were half the size of our usual panels which ensured they were able to fit through the roof space’s restricted access point.
Our operatives helped remove the existing storage tanks, installed two new fully WRAS compliant sectional GRP cold water storage tanks.
And completed all mechanical works required.
Finally, the two new cold water storage tanks were cleaned and disinfected upon completion prior to placing the system back online.
