Water Softener for the Bavois Highway Rest Area: Emergency Service and New Installation of the Fawa® Top 250

With a water hardness of 45 °fH, the existing water softening system at the Bavois (VD) rest stop unexpectedly failed. We installed a temporary solution and, at the same time, designed the high-performance Fawa® Top 250.

Customer Information

BAVOIS Nature – arguably the most beautiful stop along the A1 between Bern and Lausanne.

Located halfway between Lausanne and Yverdon-les-Bains, the Bavois Nature rest stop invites you to take a break that’s more than just a quick stop. Looking out over the vast Orbe Plain, an impressive view opens up all the way to the striking peak of the Suchet—a moment to take a deep breath, pause, and savor the moment.

Existing water softener (out of order)

Background

At the Bavois (VD) highway rest stop, the existing water softening system (Pendel 200) unexpectedly failed due to several leaks. The situation was critical: With a water hardness of about 45 °fH, there was a high risk of limescale buildup in sensitive kitchen appliances.

Temporary Solution to Bridge the Gap in Water Supply

Challenge

During the downtime, operations had to be maintained without a water softener. The entire water supply for the facility was affected—only the fire hydrants and the landscape irrigation system are not connected to the water softening system. Equipment such as the combi-steamer and the dishwasher are particularly sensitive to limescale. A fast, reliable, and cost-effective solution was needed.

Project Process in 4 Steps

A transparent overview from the failure report to final commissioning.

  • Step 1: Failure Report & On-Site Analysis – Assessment of the current condition, identification of leaks, and sizing of the temporary repair.
  • Step 2: Installation of the temporary system—a compact system for softening the entire water supply; operations continue without interruption.
  • Step 3: Design and manufacturing of the Fawa® Top 250—rated for 8 m³/day, with a peak flow rate of 12 m³/h; assembled at our manufacturing facility in Aesch, BL.
  • Step 4: Removal of the Old System & New Installation – Sanipartner Hauswirth Bursins SA installs the new bypass, and Frei AquaService delivers and commissions the Fawa® Top 250.

Solution

A compact temporary solution was installed on short notice to ensure uninterrupted operation and effectively protect the connected equipment from scale buildup. At the same time, the new, more powerful Fawa® Top 250 system was designed, manufactured, and prepared for installation.

Protection of the Entire Water Supply

The entire water supply (except for fire hydrants and garden irrigation) is protected against limescale buildup from day one—including limescale-sensitive appliances such as combi steamers and dishwashers.

Temporary Economic Solution

Not an expensive stopgap measure, but a well-thought-out two-step solution.

Sustainable improvement

Swiss water technology from our own manufacturing facility—designed for long-term operation.

Economic Efficiency and Sustainability

A water softener that is optimally adjusted offers multiple benefits—in terms of appliance lifespan, detergent usage, and energy efficiency.

Combination steamers and dishwashers without limescale buildup: up to 3–5 years longer service life.

The Fawa® Top 250's advanced control system reduces regeneration cycles and helps protect the environment.

Frequently Asked Questions About Water Softening in the Food Service Industry

This FAQ section addresses common questions from Sanipartners, building owners, and restaurant operators and helps improve the SEO visibility of the product detail page.

What level of water hardness is considered very hard?

In Switzerland, water is considered „fairly hard» at 32 °fH and „very hard» at 42 °fH. With a hardness level of about 45 °fH, the Bavois rest stop clearly falls into the upper category—a range in which water softening is no longer optional in commercial and food service settings.

Why do restaurants need a water softener?

Combination steamers, dishwashers, coffee makers, and water heaters are particularly susceptible to limescale buildup. Hard water shortens their service life, increases cleaning and maintenance costs, and raises energy consumption due to scale buildup on heating elements.

How quickly can a defective system be replaced?

We can usually install temporary solutions very quickly to ensure that operations continue. The permanent installation of a custom-designed system such as the Fawa® Top 250 is carried out in parallel and, depending on availability, can be completed within a few weeks.

Are Fawa® systems SVGW-certified?

Yes. Our water softeners in the Fawa® Soft line (2, 3, 4) are SVGW-certified (Certificate No. 2401-7280). This means they meet the requirements of the Swiss Drinking Water Ordinance.

„A heavily trafficked highway rest stop cannot afford any equipment failures. Our top priority was to protect critical infrastructure—such as combi steamers and dishwashers—without interrupting operations. The newly installed Fawa® Top 250 reliably treats the extremely hard water and guarantees Autogrill long-term operational reliability.»
