We are well into level 5 water restrictions in Cape Town, prompting most people to get creative with their water usage – we’re drilling bore holes to access more water, reusing grey water from our showers and harvesting rain water to be stored for watering our gardens and filling our pools.

But do we know how safe the water is that we store on our properties? For example, bore hole water could contain chemicals from all types of industries, waste products, sewerage contamination, pesticides from road maintenance, households and farms or E.coli, and a wide range of bacteria, viruses and parasites. Similarly, rain water that stands for weeks on end in Jojo tanks could start getting contaminated with bacteria and we wouldn’t be the wiser.

A solution to this problem is a product called the Sani Submersible UV-C, a chemical free water sanitation solution for tanks and reservoirs, manufactured locally in South Africa, which is easy to install with low maintenance. Purchase these units at Plumstead, Okavango and Atlantic Electrical and Lighting Showrooms.

How does UV-C work?

Ultraviolet germicidal irradiation (UVGI) is a disinfection method that uses short-wavelengthultraviolet (UV-C) light to kill or inactivate microorganisms by destroying nucleic acids and disrupting their DNA, leaving them unable to perform vital cellular functions.

Unlike chemical approaches to water disinfection, UV light provides rapid, effective inactivation of microorganisms through a physical process. When bacteria, viruses and protozoa are exposed to the germicidal wavelengths of UV light, they are rendered incapable of reproducing and infecting.

UV system vs an Inline water sanitation system:

Placing a submersible light in a storage tank is more effective than an inline uv system because UV light takes 15 minutes to heat up and the submersible is on 24/7 which allows enough contact time with pathogens.

Most inline systems only switch on when water passes and unless the inline system is circulating the water it would not be effective.

How easy is the Sani UV-C to install?

The Sani Submersible UV-C is a complete unit that is easily mounted in a Jojo tank or reservoir on the opposite side of the water inlet. The globe only needs to be replaced every two years. Note that it is important to wear protective eye ware when installing or maintaining the unit.
