The Regional Public Health Authority of Moravian-Silesian Region (RPHA) participates as a national health supervisor in the area of water-related hygiene and in its prevention as well. RPHA assesses projects for drinking water supply and treatment, water treatment technologies and products coming into contact with drinking water. Furthermore assesses projects for outdoor swimming pools, indoor pools and a rehab pools, including the approval of the operating rules of swimming pools, saunas and services epidemiologically significant. Inspects and supervises the quality of drinking water in public water supply systems and wells that serve as the public drinking water supply. An important aspect is the issue of the control of legionella bacteria in evaporative cooling systems. In recent years, increased attention is paid to monitoring and eventual elimination of mosquitoes.

There are 99,9% people supplied with drinking water from public water supply in the Moravian-Silesian Region. The most important production and distribution water supply system in the region is the Ostrava Regional Water Supply (OOV), which supplies more than one million inhabitants in the Moravian-Silesian Region, inhabitants in Olomouc Region and border areas in Poland. Drinking water for OOV is made from surface sources, water tanks Šance, Morávka (Beskydy mountains) and Kružberk (Jeseníky mountains). In Moravian-Silesian Region there is currently 21 large waterworks (they supplies more than 5 000 inhabitants) and 170 small waterworks (they supply less than 5 000 inhabitants). Inhabitants are predominantly supplied by drinking water made from the surface sources. There are about 300 wells used to supply drinking water to the public in Moravian-Silesian Region. From the area of the bathing water, there are 286 artificial (94 seasonal and 192 permanent), 11 natural swimming pools and 23 bathing water places in the Moravian-Silesian Region in 2017.
