LUMINOR Light Commercial Application Education - Regulated
The regulated light commercial markets involve those applications that fall under some form of regulatory jurisdiction. These can include campgrounds, schools, health care facilities, senior's homes, restaurants, day care facilities, community centers, churches, government buildings, or a number of many other applications.
Regulations vary from area to area, however the underlying concern remains the same no matter where the installation may be. Protecting public health in public places is why these regulations exist regardless of their geographical location.
In the United States, the US Environmental Protection Agency (EPA) has adopted the Ground Water Rule (GRW) which addresses disinfection protocol for groundwater with the primary directive being that of protecting public health. The GWR applies to more than 147, 000 public water systems that use ground water (as of 2003). The rule also applies to any system that mixes surface and ground water if the ground water is added directly to the distribution system and provided to consumers without treatment equivalent to surface water treatment. In total, these systems provide drinking water to more than 100 million consumers.
In Canada, regulations vary from province to province, and all have been changed as a result of the Walkerton water tragedy of 2000. In Ontario, the Safe Drinking Water Act (SDWA) continues the messages started with both Reg. 459 and Reg. 505. Under these regulations, owners of non-municipal systems are required to follow strict protocols that include performance based criteria. Quebec has taken a much stricter approach addressing the sale of water treatment devices, including UV, requiring these devices to be certified by an ANSI accredited organization (NSF International and Underwriters Laboratories).
As it stand now, the regulated markets for light commercial applications all point to the multi-barrier approach to treatment as the best possible approach. Under this multi-barrier approach, filtration, coupled with UV disinfection and residual chlorination (5-10%) appear to be the most sound approach to a multi-barrier disinfection regime.
