MACH Regulations for UV & Swimming Pools

Although many aspects of the design and construction of aquatic facilities are governed by regulation other aspects are based on custom and practice based on many years of experience. In order to address this situation in the USA the CDC (Centre for disease control) implemented the Model Aquatic Health Code (MAHC). The MAHC Code, through a Steering committee and a number of technical committees, has brought together a large group of experienced industry professionals in many diverse technologies. Wherever possible the language in the MAHC code has been based on peer reviewed science, data, and as a last resort custom and practice. The MAHC has been in development since 2005 and finally many of the various modules are available for public review. Although a standard developed for use in the USA the collation and use of the latest science is expected to create a document that many aquatic facility regulators around the world will utilise as a reference for their own local regulations. One of the areas of the MAHC code is the application of UV disinfection, particularly for the control of cryptosporidium. Ultraviolet Disinfection treatment Ultraviolet disinfection is now an established method of water treatment for municipal pools, and has become the preferred treatment choice for a number leading international leisure brands and new-build or renovated swimming pools.
