Domestic water disinfection involves the controlled dosing of disinfectants, such as sodium hypochlorite, to eliminate harmful microorganisms from domestic water systems. Chlorination is a proven method used to prevent the spread of waterborne diseases including cholera, dysentery and typhoid, and to maintain compliance with UK water hygiene legislation.
