The scene is perfect. The Casablanca sun warms the loungers, and the pool glitters with an irresistible blue shimmer. The urge to dive in is immediate, especially after a long flight or before catching another from the nearby Mohammed V Airport. Yet, a small voice of doubt often remains. Is this water truly clean? For parents with young children, people with sensitive skin, or simply discerning travellers, this question isn't a minor detail—it's a prerequisite. Hygiene comes first. Faced with this legitimate concern, which is rarely addressed with full transparency, we decided to investigate. We went behind the scenes and into the technical rooms of the ONOMO Airport Casablanca to understand, in concrete terms, what guarantees the quality of your swim.
Clear, healthy pool water depends on a strict chemical and mechanical balance—an inseparable trio of neutral pH, an effective disinfectant level, and constant filtration. Contrary to popular belief, a strong "chlorine" smell is not a sign of cleanliness. In fact, it's a symptom of chloramines, compounds formed when chlorine reacts with organic matter like sweat and dead skin cells. These are the real culprits behind eye and skin irritation. A perfectly balanced pool, on the other hand, is virtually odourless.
The key is the pH level, ideally maintained between 7.2 and 7.4. If it's too low, the water becomes acidic and aggressive; too high, and the chlorine loses its disinfecting power. Finally, filtration, handled by powerful pumps and sand filters, continuously removes physical impurities. These principles are governed by health standards, but the best establishments go above and beyond.
ONOMO Airport Casablanca doesn't just meet the standards; it has implemented a monitoring protocol that exceeds minimum requirements to ensure impeccable water quality. Our investigation allowed us to verify several key points:
This commitment to excellence provides the peace of mind that makes the idea of enjoying this clean oasis so appealing. It transforms a simple dip into a truly relaxing experience, especially when you have a private retreat for a few hours to rest afterwards, like a Standard room at the hotel.
The commitment to impeccable hygiene isn't an isolated initiative in Casablanca. It's a quality policy applied across the ONOMO group, particularly in its hotels strategically located near airports. The ONOMO Hotel Abidjan Airport, serving Félix-Houphouët-Boigny Airport, applies the same rigorous protocols. For the business traveller in transit between these two economic capitals or the tourist exploring West Africa, this ensures a consistent standard of trust. Whether your layover is in Morocco or Côte d'Ivoire, the promise is the same: a haven of peace and cleanliness. It's the guarantee of being able to relax with complete serenity by booking an Onomo Standard room in Abidjan or treating yourself to the comfort of a more spacious Onomo Supérieure room before your next flight.
For what is often a small additional cost, booking a day-use room through Siestify offers incomparable added value compared to a simple pool access pass. Hygiene and comfort don't stop at the water's edge. The real luxury is having a completely private space. The choice between a crowded public beach and a private pool becomes much clearer when you consider the benefits of a personal base.
Here’s a breakdown of what you get with a day room:
This transforms a quick swim into a full day of restorative relaxation, a strategy that savvy travellers are increasingly adopting. For more insights on accessing hotel pools, our no-membership guide is a must-read.
Is the pool safe for young children?
Yes, the water quality is rigorously controlled to be safe for everyone, including the youngest swimmers. The pH and chlorine levels are carefully balanced to prevent skin and eye irritation, making it a reassuring choice for families.
Is there a strong chlorine smell around the pool?
No, and that's a sign of healthy water. A strong "chlorine" smell actually comes from chloramines, which form when chlorine reacts with impurities. Well-treated and balanced water, like that at ONOMO, has a very neutral scent.
Are the pool surroundings (sunbeds, floors) also cleaned?
Absolutely. ONOMO's hygiene protocols include daily cleaning and disinfection of the pool decks, sun loungers, showers, and footbaths to ensure a comprehensively clean environment.
Who checks the water quality and how often?
The water quality is checked multiple times a day by the hotel's technical teams. Manual tests are conducted in the morning, at midday, and in the evening, supplemented by automatic probes that adjust the levels in real-time. A sanitary logbook records all these readings.
Can I just come for the pool without booking a room?
While some hotels may offer a day pass, booking a room for a few hours is often a much better value. As detailed in our guide on whether you can just walk in for a swim, a day room guarantees access and provides a private shower, a secure place for your belongings, and a bed to rest, turning a simple swim into a true daycation.
