Why do I need to connect my water dispenser to the mains supply?

A brief primer on point-of-use superiority

Yes, you will need to be connected to a mains water supply. Borg & Overström only supply mains-fed water coolers and tap systems. There are many benefits to this – covering the areas of sustainability, cost-saving, user efficiency, and hygiene. We believe it is our responsibility to make use of the latest available technology in a safe, sustainable way, and it can only be done through POU.  

POU is cheaper and safer

First, know that POU will be much cheaper for you in the long term. If you’re feeling sceptical and want a more precise figure, bespoke to your business, you can calculate money saved with our bottle versus mains-fed savings calculator

From the standpoint of practicality and hygiene, the main reason we only supply mains-fed machines is because of the chilling systems we use. Direct Chill™ and Dry Chill® are far more hygienic and energy-efficient than traditional reservoir cooling systems, as they speed up the chilling process while keeping the water sealed against external contaminants. 

The aluminium-encased Dry Chill® system is sealed so thoroughly, it is able to cool incoming and outgoing water without once exposing it to air. Additional innovative technology laid out in our Totality® methodology keeps the dispensing experience germ-free for the internal and external functions of all machines.

Not only do these chilling systems instantly chill and keep water cold, they manage to do so in a way that is demonstrably measurable and repeatable. Compare this steady consistency with the following information.

POU is better for quality control and sustainability

The quality of bottled water varies so much, it requires certain treatments which may leave chemical residue impacting purity and flavour. There is just as much variation to be found in the production line of multi-gallon water bottles, especially for quality control and cross-contamination protocol.

Water bottles must be transported, often over vast distances by high-emission vehicles. The logistical difficulties of storage – such as low temperature requirements and mandatory shading from sunlight, open up bottles to the dangers of human error. Storage in inappropriate places will result in bottles absorbing unpleasant external odours, even developing internal algae. 

Even in a perfectly safe and efficient system of manufacture, transportation and storage, bottles are often stored for long periods exceeding the recommended three to nine months. This undoes all previous control methods.   


Despite the best intentions and efforts of designers, manufacturers and users of bottled systems, there is no way to outright eliminate these risks. POU is here to stay.
