way to decrease the incidence of cholera was to improve water‚ sanitation‚ and hygiene. There needs to be treated water that is accessible to the people. NGO’s and agencies gathered to make some change. The concern was the piped water supply for chlorination. Purifying water tablets were distributed to homes. The main challenge was distributing the purifying water tablets to homes that were in difficult to reach areas. Educating the public was key. Information about boiling drinking water and seeking

Pre-conditioning – Water rich in hardness salts is treated with soda-ash (sodium carbonate) to precipitate calcium carbonate out utilising the common-ion effect. 5. Pre-chlorination – In many plants the incoming water was chlorinated to minimise the growth of fouling organisms on the pipe-work and tanks. Because of the potential adverse quality effects (see chlorine below)‚ this has largely been discontinued.[citation needed]
