At TRINITY Hotels, we make sure that our guests can enjoy the water attractions to the fullest - without fear. The cleanliness of the water in the indoor and outdoor pools, as well as in the water park, is crucial to us and we pay the utmost attention to it on a daily basis.
Expert analyses every month
In each of our hotels - Hotel Senec, Hotel Sitno, Hotel Atrium - as well as in Aquapark Senec, regular testing of water quality is carried out by an accredited laboratory. These analyses are carried out once a month in accordance with the legislation in force (Decree No. 308/2012 Coll. of the Ministry of Health of the Slovak Republic) and are focused on physico-chemical, microbiological and biological parameters of water.
Internal check several times a day
In addition to laboratory tests, our staff performs water purity checks several times a day. In particular, they monitor pH, chlorine, transparency and overall water purity. Any deviation is immediately addressed to ensure maximum safety and comfort for all visitors.
