Green Heat: How AquaNat’Our Uses On-Site Biogas to Warm Pools and Showers

Looking for a swim that feels great and does good? AquaNat’Our warms its pools and utility water with on-site biogas, turning local farm waste into green heat so you can enjoy your laps, family time, and wellness routines with a lighter environmental footprint. In this guide, you’ll learn what on-site biogas is, how it helps heat our pools and showers, and how it fits into a broader set of sustainability measures that make your visit both refreshing and responsible.

What is biogas—and why is it ideal for warm water?

Biogas is a renewable fuel produced when microorganisms break down organic matter (like agricultural residues) in oxygen-free conditions. The resulting gas can be burned to generate heat. For facilities with steady hot-water needs—such as swimming pools and showers—biogas provides a consistent, low-fossil alternative for maintaining comfortable temperatures throughout the day.

In practical terms, biogas aligns well with pool operations because:

• Warm water demand is continuous and predictable.
• Heat can be delivered on demand for pools and utility areas.
• Local organic material becomes useful energy rather than waste.

How AquaNat’Our turns local waste into warm water

AquaNat’Our heats its pool and utility water with biogas produced on-site at Parc Hosingen, using organic waste supplied by local farmers. This short, circular loop keeps energy generation close to where it’s used, reduces transport needs, and minimizes the reliance on fossil fuels for daily operations.

Here’s the high-level flow:

1. Local farmers provide organic waste.
2. The material is processed in an on-site biogas setup at Parc Hosingen.
3. The biogas is combusted to produce heat.
4. Heat is distributed to warm pool water and utility water (e.g., showers and facility needs).

The result: a reliable, renewable on-site biogas source that supports stable pool temperatures and comfortable showers—without defaulting to conventional fuels.

Where you’ll feel the difference: pools and temperatures

Guests often ask, “Which pools benefit from this green heat?” At AquaNat’Our, the warm water you enjoy is part of a smarter energy system:

• Swimming Pool – 28 °C (12.5 m × 25 m): Ideal for lap swimming, with an adjustable movable floor from 0.45 m to 1.80 m. Two lanes are typically reserved for undisturbed training, except during Saturday animations.
• Teaching Pool – 33 °C (8 m × 12.5 m, depth 1.35 m): Optimized for aqua fitness and swimming lessons for all ages.
• Warm Pool – 36 °C: Unwind with bubble loungers, massage jets, and neck showers that help ease tension and reduce stress.
• Cold Pool – 16 °C: A bracing cool-down to stimulate circulation and support recovery after training.
• Diving Area – 1 m springboard & 3 m platform: For visitors who love a jump or dive as part of their routine.

By pairing comfortable water temperatures with on-site biogas, we link guest experience to a local, renewable energy cycle.

Beyond green heat: smart water and energy management

On-site biogas is only one part of the picture. AquaNat’Our has implemented several measures that conserve resources and elevate hygiene and comfort:

• Efficient water treatment: A modern Bremag system enables AquaNat’Our to recycle up to 80% of pool water that would otherwise go to the sewer, significantly conserving this valuable resource.
• Chlorination with salt tablets: We have converted the chlorine system to salt tablets instead of chlorine granules, combined with eco-friendly cleaning agents and ecological paper at registers to reduce chemical and material impacts.
• Waste management: Microfiber towels replace paper towels in the fitness area. Waste is carefully separated, with disposal handled in cooperation with regional recycling companies.
• Energy-saving technologies: Water-saving shower heads from Illé, energy-efficient LED lighting, and motion detectors help reduce consumption without compromising comfort.

Together, these steps complement green heat by reducing overall demand, reclaiming water, and cutting unnecessary waste.

Quick answers: featured snippet–ready

• What is on-site biogas?
  A renewable gas made from organic waste processed locally and used to produce heat for pools and utility water.

• How does AquaNat’Our use biogas?
  The pool and utility water are heated with biogas produced on-site at Parc Hosingen from organic waste provided by local farmers.

• What other sustainability measures are in place?
  Up to 80% pool water recycling with a Bremag system, salt-tablet chlorination, eco-friendly products, microfiber cleaning in fitness, waste separation with regional recyclers, and energy-saving fixtures and lighting.

Why local sourcing matters

Using organic waste from nearby farms means energy and materials stay within the community. This supports a regional resource loop, reduces transport distances, and gives agricultural by-products a valuable second life as green heat for your swim and shower.

Safety, inclusion, and accessibility

AquaNat’Our emphasizes a clean, safe, and welcoming environment where accessibility matters. The facility carries the EureWelcome label, with barrier-free access that includes a pool lift, wheelchair-accessible showers and toilets, and accessible changing rooms. Everyone should be able to benefit from sustainable comfort.

Sustainability you can see (and feel)

What does all this mean for your visit?

• Consistent, comfortable water temperatures powered in part by on-site biogas.
• Cleaner-feeling swims supported by salt-tablet chlorination and modern filtration.
• Thoughtful resource use—from LEDs and motion detectors to Bremag water recycling—that aligns your wellness time with environmental care.

Practical takeaways: how you can help on your next visit

Small actions multiply the impact of our green heat and conservation efforts.

• Rinse thoroughly before entering the pools to keep water cleaner longer.
• Follow our posted pool and house rules for safe, efficient operations.
• Use the on-site towel and robe rental service when needed and return items for reuse.
