The Well Water adopted Petainer water cooler bottles to move away from polycarbonate as scrutiny of BPA intensified across Europe. The switch supported a reusable delivery model while improving washability, seal performance, and bottle durability for bulk water distribution.
The Well Water t/a Purely Scottish Bottlers Limited is a UK natural mineral water bottler. Working with Petainer, the business moved a number of clients from polycarbonate to PET water cooler bottles as concern around BPA continued to grow and customer expectations shifted.
By the Numbers
For The Well Water, the challenge was not simply finding another bottle material. It was finding a practical replacement for polycarbonate that could support a reusable delivery model while addressing growing concern around BPA in food-contact materials.
That made long-term material choice more important. As regulatory scrutiny increased and the market moved towards a [20 Jan 2029 EU transition deadline](/), PET offered a BPA-free route that aligned with where the category was heading without changing the fundamentals of the reusable delivery model.
The Well Water adopted Petainer water cooler bottles with handles as part of its reusable supply model. Unlike some polycarbonate options, the handle is not integrated into the body of the bottle, which helps improve washing performance between uses.
That matters in water delivery because bottles are filled, delivered, returned, washed, and filled again. For a reusable format to work, the bottle has to stay easy to clean, robust in handling, and reliable in use across both logistics and customer environments.

For The Well Water, the benefits went beyond material choice. Petainer water cooler bottles are designed for repeated use and tested for durability, with many reuses possible, up to 40 times. In the 19L format, the bottle also combines high capacity with a lightweight 669g design, helping support repeated handling across delivery and return cycles.
PET also helped solve practical delivery issues. The smoother neck of the bottle provides a better seal than polycarbonate, helping reduce leaks, which is a key concern in bulk water distribution. Combined with stronger washability, that gave The Well Water a bottle format better suited to day-to-day reusable operations.
The Well Water shows how PET water cooler bottles can help delivery businesses move away from polycarbonate without giving up the benefits of a reusable bottle system. For operators balancing product safety, operational reliability, and customer expectations, that combination matters.
For water brands and delivery services, PET offers a practical route to combine BPA-free material choice, repeated reuse, easier washing, and better sealing performance in one bottle format. That makes it a strong fit for bulk hydration models built around return, refill, and repeat use.
